Gamers using monitors from brands like ASUS or LG often encounter issues that require fixes such as checking the physical integrity of the cord or updating the graphics drivers, which are frequently updated by companies like NVIDIA. Professionals in fields like graphic design also rely on a stable HDMI connection between their graphics card and monitor for accurate image display. When these connections falter, troubleshooting steps, often found in the monitor’s user manual, become essential to restore optimal performance.

Understanding HDMI: The Foundation of Visual Connection

HDMI, or High-Definition Multimedia Interface, is the backbone of modern digital displays.

It’s the unseen hero that brings your computer’s visuals to life on your monitor.

Before diving into troubleshooting those frustrating HDMI issues, it’s essential to understand the fundamentals of this technology and the key players involved.

This section provides that foundational knowledge.

What Exactly Is HDMI?

At its core, HDMI is a digital interface designed to transmit high-definition video and audio signals from a source device (like your computer’s graphics card) to a display device (your monitor).

Think of it as a digital pipeline carrying both the picture and the sound.

Unlike older technologies like VGA, which carried analog signals, HDMI uses a digital signal.

This eliminates the need for digital-to-analog conversion, resulting in a cleaner, sharper, and more accurate image.

Why has HDMI become the dominant standard?

Its advantages are numerous:

• High Bandwidth: HDMI can handle high resolutions and refresh rates, including 4K and even 8K.
• Digital Purity: The digital signal ensures minimal signal degradation, delivering a pristine image.
• Audio Integration: It carries both video and audio, simplifying connections.
• Content Protection: HDMI incorporates HDCP (High-bandwidth Digital Content Protection) to prevent unauthorized copying of digital content.

Key Components in the HDMI Chain

The journey of an HDMI signal from your computer to your monitor involves several crucial components, each playing a vital role.

Understanding these components helps pinpoint where potential problems might arise.

The Computer Monitor: The Destination

The monitor is the final destination of the HDMI signal.

It receives the digital data and translates it into the image you see on the screen.

Monitors vary in their supported resolutions, refresh rates, and HDMI versions.

It’s crucial to ensure that your monitor is compatible with the output of your graphics card to avoid issues.

Graphics Card (GPU): The Originator

The graphics card, or GPU, is responsible for generating the video signal that is sent through the HDMI port.

It processes the visual information from your computer and encodes it into a format that can be transmitted via HDMI.

A powerful GPU is essential for displaying high-resolution content and smooth frame rates, especially for gaming or video editing.

The GPU’s HDMI output capabilities also dictate the maximum resolution and refresh rate that can be achieved.

HDMI Cable Types: The Messenger

The HDMI cable acts as the messenger, carrying the video and audio signal from the GPU to the monitor.

However, not all HDMI cables are created equal. Different standards support different bandwidths and features.

Here’s a quick breakdown:

• Standard HDMI: Supports up to 1080i resolution.
• High-Speed HDMI: Supports 1080p, 4K (at 30Hz), and 3D video.
• Premium High-Speed HDMI: Supports 4K (at 60Hz) with HDR. Often necessary for modern displays.
• Ultra High-Speed HDMI: Supports 8K and 4K (at 120Hz) with HDR. The latest standard for future-proofing.

Choosing the right cable is essential to ensure that your monitor receives the full benefit of your GPU’s capabilities.

A low-quality or outdated cable can limit the resolution and refresh rate, leading to a subpar visual experience.

HDMI Connectors: The Interface

Finally, HDMI connectors are the physical interfaces that connect the cable to the devices.

While most devices use the standard Type A connector, other types exist:

• Type A (Standard): The most common type, found on most computers, monitors, and TVs.
• Type C (Mini HDMI): Smaller connector often used on camcorders and some laptops.
• Type D (Micro HDMI): Even smaller connector used on smartphones, tablets, and action cameras.

Adapters can be used to connect different connector types, but it’s generally best to use the appropriate cable whenever possible to minimize potential signal loss or compatibility issues.

Recognizing the Symptoms: Common HDMI Problems

HDMI, or High-Definition Multimedia Interface, is the backbone of modern digital displays. It’s the unseen hero that brings your computer’s visuals to life on your monitor. But what happens when this connection falters? To effectively troubleshoot HDMI issues, you first need to accurately identify the symptoms. Let’s break down some of the most common problems.

The Dreaded "No Signal" Error

That heart-sinking moment when your monitor displays "No Signal." What does it mean? Simply put, your monitor isn’t receiving a video signal from your computer.

This could stem from a variety of causes:

• A disconnected or loose HDMI cable.
• The wrong input source selected on your monitor.
• A faulty HDMI port on your computer or monitor.
• More rarely, a deeper hardware or software issue.

Immediate First Steps

Don’t panic! Start with the basics.

First, ensure the HDMI cable is securely plugged into both your computer and your monitor.

Next, check that your monitor is set to the correct HDMI input. Use the monitor’s menu buttons to cycle through the available inputs.

If that doesn’t work, try restarting both your computer and monitor.

Sometimes, a simple reset is all it takes.

Pixelation, Artifacts, and Distorted Images: A Visual Nightmare

These symptoms manifest in various unpleasant ways. Pixelation appears as blocky or grainy textures on the screen. Artifacts are visual anomalies, like strange lines, color distortions, or flickering patterns. Distorted images might appear stretched, squashed, or blurry.

What’s behind these visual gremlins?

• Faulty HDMI Cable: A damaged or low-quality cable can struggle to transmit the full signal, especially at higher resolutions.

• Bandwidth Limitations: Attempting to display a resolution or refresh rate that exceeds the cable’s or device’s capabilities.

• Driver Issues: Outdated or corrupted graphics drivers can wreak havoc on image rendering.

• GPU Problems: In more serious cases, it could point to a failing graphics card.

Visual Examples

Imagine watching a movie, and suddenly, faces become blocky and indistinct – that’s pixelation. Or, picture playing a game, and seeing random, shimmering lines across the screen – those are artifacts.

These visual imperfections indicate a problem with the signal transmission or processing.

Intermittent Signal Loss: The Frustrating Flicker

Imagine this: you’re working or gaming, and suddenly, your screen goes black for a second or two, then returns. This is intermittent signal loss.

This flickering can be incredibly disruptive and often points to a connectivity issue that’s on the edge.

Common culprits include:

• Loose Cable: A slightly loose HDMI connection can cause the signal to drop momentarily.

• Overheating GPU: When your graphics card gets too hot, it might struggle to maintain a stable output.

• Cable Strain: A cable that is bent sharply or stretched can also cause temporary signal loss.

Intermittent issues can be trickier to diagnose. Pay close attention to when the problem occurs – is it during graphically intensive tasks? Does it happen more frequently when the computer has been running for a long time?

Step 1: The Foundation – Basic Checks and Power Cycling

HDMI issues can be frustrating, but before diving into complex solutions, it’s crucial to start with the basics. Often, the simplest steps can resolve the problem. Think of it as a doctor triaging a patient: assess the obvious before ordering expensive tests.

This section focuses on the initial, easiest troubleshooting steps: ensuring secure connections, power cycling devices, and verifying input selection. These are the first lines of defense against common HDMI glitches.

Secure Cable Connections: The Obvious Culprit

It might seem too simple, but loose or poorly connected HDMI cables are a frequent cause of signal problems.

The HDMI cable is the physical bridge that delivers your video signal. A loose connection means incomplete data transfer.

Therefore, the first step is to ensure the HDMI cable is firmly plugged into both the computer and the monitor. Don’t just glance at it; give it a gentle push to ensure it’s fully seated in the port.

Feel for a click or a solid connection.

Also, inspect the connectors for any signs of damage. Bent pins, corrosion, or physical damage to the connector can prevent a solid connection. If you see any damage, replacing the cable is advisable.

Power Cycling: The Digital Reset Button

Think of power cycling as a digital reset. Electronic devices sometimes get "stuck" in a state that prevents proper HDMI communication.

Power cycling clears temporary glitches and forces a fresh handshake between devices.

To power cycle effectively, turn off both the computer and the monitor completely. Unplug them from the power outlet if possible.

Wait for about 30 seconds to a minute. This allows any residual electricity to dissipate, ensuring a complete reset.

Then, plug the devices back in and turn them on. Turning on the monitor first, then the computer, is often the most effective way to re-establish the connection. This allows the monitor to be ready to receive the signal when the computer boots up.

Verifying Input Selection: Are You on the Right Channel?

Monitors often have multiple input sources (HDMI 1, HDMI 2, DisplayPort, etc.). If the monitor is set to the wrong input source, it won’t display the signal from your computer, even if everything else is working correctly.

You may see a "No Signal" message if the input is wrong, or the screen might remain black.

Locate the monitor’s buttons or menu controls. These are usually found on the front, side, or back of the monitor. Navigate through the menu to find the "Input Source" or "Source Selection" option.

Ensure the correct HDMI input is selected. It might be labeled as HDMI 1, HDMI 2, or simply HDMI, depending on the monitor model.

Consult your monitor’s manual if you’re unsure how to access or navigate the OSD menu.

Step 2: Cable and Hardware Diagnostics

After exhausting the basic checks, it’s time to roll up your sleeves and dive into the hardware itself. The HDMI cable, any adapters involved, and the ports themselves are all potential culprits when chasing down a visual gremlin.

This section zeroes in on diagnosing these physical elements, helping you isolate whether the problem lies in the wires and connectors, or if it’s time to investigate deeper.

Testing the Integrity of Your HDMI Cable

The HDMI cable is the lifeline between your computer and monitor. A faulty cable is one of the most frequent causes of HDMI issues.

It might seem obvious, but the first step is to visually inspect the cable. Look for any obvious signs of damage: frayed ends, kinks, or exposed wiring.

Even if it looks fine on the outside, the internal wires could be damaged. Here’s how to rigorously test the cable:

• The Swap Test: The easiest and most effective method is to swap the existing HDMI cable with one you know is working correctly. Borrow one from another device (like your Blu-Ray player or gaming console) if necessary. If the problem disappears with the new cable, the old cable was the issue.

• Cross-Device Check: Connect the HDMI cable to a completely different setup. Plug your computer into a TV using the suspect cable, or vice versa. If the problem follows the cable to the new setup, then the cable is indeed the culprit.

If you’ve determined that the cable is the problem, don’t waste time trying to repair it. HDMI cables are relatively inexpensive to replace.

Bypassing the Adapter Jungle

Adapters and splitters are common in multi-display setups, but they can also be a significant source of HDMI headaches. While they offer added convenience, they can sometimes introduce compatibility issues or signal degradation.

These devices can sometimes struggle to pass the full bandwidth required for high resolutions or refresh rates, especially if they’re older or of questionable quality. When troubleshooting, simplification is key.

Temporarily remove any HDMI adapters, converters (like DisplayPort to HDMI), or splitters from the connection chain.

Connect your computer directly to the monitor using only the HDMI cable. Did the problem vanish when you removed the adapter? If so, the adapter was likely the issue.

Consider replacing it with a higher-quality alternative or simply doing without if possible. Remember, fewer components mean fewer potential points of failure.

Exploring Alternate HDMI Ports

Just like any other electronic component, HDMI ports can fail. A port on your graphics card or monitor might be damaged, loose, or simply not functioning correctly.

The solution is straightforward: try all available HDMI ports on both your computer (specifically the graphics card) and your monitor.

• Systematic Port Testing: Methodically try each port, one at a time. After plugging the cable into a new port, give your system a moment to recognize the connection.

• Look for Physical Damage: Before plugging into a port, visually inspect it. Look for bent pins or debris that might be obstructing the connection. Never force a cable into a port.

If one port works while another doesn’t, you’ve likely identified a faulty port. While you might continue using a working port, be aware that the faulty one may need professional repair if you require multiple displays.

Step 3: Software and Driver Scrutiny

After exhausting the basic checks, it’s time to move from hardware to software. Sometimes, the culprit isn’t a faulty cable, but rather an issue with your graphics drivers or display settings.

This section zeroes in on these software elements, helping you isolate and resolve problems that stem from outdated or misconfigured settings.

Graphics Driver Updates and Rollbacks

Your graphics driver is essentially the translator between your operating system and your graphics card. Outdated, corrupted, or incompatible drivers are a common source of HDMI problems. Let’s explore how to keep them in check.

Updating Drivers: Keeping Your Graphics Card Current

Keeping your graphics drivers up-to-date is crucial.

New drivers often include performance improvements, bug fixes, and compatibility updates for the latest games and applications.

Here’s how to update drivers for the major graphics card manufacturers:

• NVIDIA:

It’s generally best practice to perform a "clean installation" when updating drivers. This removes any previous driver files and settings, preventing potential conflicts. The NVIDIA and AMD installers usually offer this option.

Rolling Back Drivers: Reverting to a Stable State

Sometimes, a new driver update can introduce unexpected issues.

If you start experiencing HDMI problems immediately after a driver update, consider rolling back to a previous version.

Here’s how to roll back drivers in Windows:

1. Press Win + X and select "Device Manager."
2. Expand "Display adapters."
3. Right-click on your graphics card and select "Properties."
4. Go to the "Driver" tab.
5. If the "Roll Back Driver" button is available (not greyed out), click it and follow the prompts.

Before updating any drivers, it’s wise to create a system restore point.

This allows you to easily revert your system to a previous state if something goes wrong.

Display Settings Configuration

Even with the correct drivers installed, incorrect display settings can lead to HDMI-related issues. Let’s examine the key settings to configure.

Resolution: Matching Your Monitor’s Native Capabilities

Setting the correct screen resolution is vital for a sharp and clear image. Using an incorrect resolution can result in a blurry, stretched, or distorted display.

Here’s how to adjust the screen resolution in Windows:

1. Right-click on the desktop and select "Display settings."
2. In the "Display resolution" dropdown menu, choose the recommended resolution for your monitor.
3. If you’re unsure, consult your monitor’s documentation or specifications.

Refresh Rate: Achieving Smooth Visuals

The refresh rate determines how many times per second your monitor updates the image on the screen. A higher refresh rate results in a smoother and more responsive visual experience.

Here’s how to set the refresh rate in Windows:

1. Right-click on the desktop and select "Display settings."
2. Scroll down and click "Advanced display settings."
3. In the "Choose a refresh rate" dropdown menu, select the desired refresh rate.
4. Most monitors support 60Hz, but higher refresh rates (e.g., 120Hz, 144Hz) may be available depending on your monitor and graphics card.

Multiple Displays: Configuring a Multi-Monitor Setup

If you’re using multiple monitors, proper configuration is essential.

Here’s how to configure multiple displays in Windows:

1. Right-click on the desktop and select "Display settings."
2. Windows should automatically detect all connected monitors.
3. If a monitor isn’t detected, click the "Detect" button.
4. Use the "Identify" button to determine which monitor is which.
5. In the "Multiple displays" dropdown menu, choose how you want the monitors to behave (e.g., "Extend these displays," "Duplicate these displays").

Setting the primary display is important.

The primary display is where the taskbar and most applications will appear by default.

You can set the primary display by selecting a monitor and checking the "Make this my main display" box.

Step 3: Software and Driver Scrutiny
After exhausting the basic checks, it’s time to move from hardware to software. Sometimes, the culprit isn’t a faulty cable, but rather an issue with your graphics drivers or display settings.

This section zeroes in on these software elements, helping you isolate and resolve problems that stem from outdated or misconfigured drivers, or incorrect display settings.

Step 4: Advanced HDMI Troubleshooting Techniques

Sometimes, basic troubleshooting doesn’t cut it. Diving deeper requires understanding the arcane realms of display technology. We’re talking about EDID and HDCP – protocols that, while often invisible, can wreak havoc on your HDMI connection.

Demystifying EDID (Extended Display Identification Data)

EDID is essentially how your monitor introduces itself to your graphics card. Think of it as a digital handshake.

It’s a data structure that contains crucial information about your display, including its supported resolutions, refresh rates, and other capabilities.

This data allows your computer to output a compatible signal, ensuring a clear picture. When EDID goes wrong, you might encounter incorrect resolutions, a blank screen, or other display anomalies.

How EDID Issues Manifest

Common symptoms of EDID problems include:

• The monitor displays a resolution it shouldn’t (e.g., stretched or squashed image).
• The monitor isn’t recognized by the operating system.
• Inability to select the monitor’s native resolution.
• The monitor showing only a black or garbled screen.

Resolving EDID Problems

Troubleshooting EDID issues often involves a combination of approaches:

• Restart Everything: Yes, the classic "turn it off and on again" can sometimes force a re-negotiation of the EDID.
• Update Graphics Drivers: As always, ensure your graphics drivers are up to date. Outdated drivers can struggle with EDID interpretation.
• Check Monitor Firmware: Some monitors have firmware updates that address EDID-related bugs. Consult your monitor’s manual or the manufacturer’s website.
• Force EDID Override: This is a more advanced technique. Some graphics card drivers allow you to manually override the EDID data. Exercise caution when doing this, as incorrect settings can lead to display problems. Research specific instructions for your graphics card model.
• EDID Emulators/Repeaters: Hardware devices exist that can "learn" and relay EDID information, often used in complex setups with multiple displays.

Understanding HDCP (High-bandwidth Digital Content Protection)

HDCP is a copy-protection technology designed to prevent the unauthorized duplication of digital content. It ensures that only authorized devices can view protected material.

While well-intentioned, HDCP can be a major headache. It often causes compatibility issues between devices, leading to frustrating playback errors.

How HDCP Interference Occurs

HDCP problems commonly arise when:

• One or more devices in the HDMI chain don’t support HDCP.
• HDCP handshakes fail between devices.
• Using older devices (DVD players, older monitors) with newer content sources.

Common HDCP Symptoms

You might be facing HDCP issues if you encounter these problems:

• A blank screen when trying to play protected content (e.g., Blu-ray movies, streaming services).
• Error messages related to HDCP or content protection.
• Intermittent signal loss or flickering during playback.
• Downgraded video resolution due to HDCP restrictions.

Strategies to Mitigate HDCP Issues

Unfortunately, circumventing HDCP is generally not recommended due to legal implications and potential instability. However, you can try these approaches:

• Ensure HDCP Compatibility: Make sure all devices in your HDMI chain (source device, receiver, display) support the same HDCP version.
• Update Device Firmware: Update the firmware on your devices to the latest versions. This can sometimes resolve HDCP compatibility issues.
• Simplify the HDMI Chain: Remove any unnecessary devices or adapters from the HDMI chain to minimize potential points of failure.
• HDCP Strippers (Use with Caution): Devices exist that strip the HDCP signal. However, their use is often legally questionable and may violate copyright laws. Proceed with extreme caution and be aware of the potential consequences.
• Bypass HDCP (Not Recommended): Some older devices may allow you to disable HDCP, but this is not a recommended solution and may prevent you from playing protected content.

Understanding Bandwidth, Content Protection, and Signal Interference

After exhausting software and hardware solutions, it’s time to understand the often-overlooked factors that can significantly impact HDMI performance: bandwidth limitations, content protection (HDCP), and signal interference. These elements can be silent culprits, undermining even the best cables and devices. Understanding their influence is key to unlocking a stable and optimal viewing experience.

Bandwidth: The Data Pipeline

Think of bandwidth as the width of a pipe carrying data. The higher the resolution and refresh rate of your content, the more data needs to flow through that pipe. HDMI cables and devices have maximum bandwidth capacities. If the content’s data demand exceeds that capacity, you’ll likely experience issues like black screens, flickering, or reduced image quality.

Cable Types and Bandwidth

HDMI cables are categorized by their speed and bandwidth capabilities. Older "Standard" cables are insufficient for modern 4K content, while "High-Speed" cables are a better fit. For demanding 4K HDR or 8K content, you will need Premium High-Speed or Ultra High-Speed cables.

Using an outdated cable for high-resolution content is a very common mistake. So, always check that the cable meets the bandwidth requirements of the devices and content that you are trying to connect.

Device Capabilities

It’s not just the cable—the HDMI ports on your source device (e.g., PC graphics card) and display also have bandwidth limitations. Make sure both devices support the HDMI version and features required for your desired resolution and refresh rate.

If your monitor only supports HDMI 2.0, even an HDMI 2.1 cable won’t enable features beyond the HDMI 2.0 specification. The weakest link in the chain determines the overall performance.

Content Protection (HDCP) Revisited

HDCP (High-bandwidth Digital Content Protection) is designed to prevent the unauthorized copying of digital content. While well-intentioned, it can unfortunately lead to frustrating compatibility issues.

The HDCP Handshake

HDCP works by requiring a "handshake" between the source device (e.g., streaming device, Blu-ray player) and the display. If the handshake fails, the content might be displayed at a lower resolution or not at all.

Common HDCP Problems

HDCP issues are often related to outdated devices, faulty cables, or compatibility problems between devices. Sometimes, simply restarting the devices in the chain can resolve handshake failures.

If you’re using a splitter or adapter, it might not fully support HDCP. This can also cause problems, especially with DRM-protected content like streaming movies.

Signal Interference: Unwanted Noise

External factors can introduce interference into the HDMI signal, leading to visual anomalies.

Sources of Interference

Common sources include:

• Other electronic devices: Power cords, microwaves, and other appliances can generate electromagnetic interference (EMI).
• Long cable runs: The longer the HDMI cable, the more susceptible it is to signal degradation.
• Poorly shielded cables: Inexpensive cables might not have adequate shielding, making them prone to interference.

Mitigation Strategies

Fortunately, you can take steps to minimize signal interference:

• Use shielded HDMI cables: These cables have extra layers of protection to block out EMI.
• Keep cables away from power cords: Physically separate HDMI cables from power cords and other potential sources of interference.
• Shorten cable runs: If possible, use shorter HDMI cables to minimize signal degradation over long distances.

Understanding these factors allows for better diagnosis of HDMI issues, especially when standard troubleshooting steps don’t yield any solutions. By addressing bandwidth limitations, HDCP compatibility, and signal interference, you can significantly improve the reliability and quality of your HDMI connections.

Leveraging the Monitor’s On-Screen Display (OSD)

After exhausting software and hardware solutions, it’s time to explore the capabilities of your monitor itself. The On-Screen Display (OSD) is a menu system built into most monitors, offering a range of adjustments that can sometimes resolve HDMI-related issues or, at the very least, improve your viewing experience. Don’t underestimate this tool.

Accessing and Navigating the OSD

Finding the OSD is usually straightforward. Look for a set of physical buttons on the monitor’s bezel, typically along the bottom or side. The power button is usually separate, so don’t confuse it.

Common button labels include "Menu," "Enter," "Source," "Up," and "Down."

Pressing the "Menu" button should bring up the OSD. From there, use the directional buttons to navigate through the different settings categories. Press "Enter" to select an option and further directional buttons or "+/-" buttons to adjust settings.

Each monitor model varies, so consult your monitor’s manual if you are having trouble finding the physical buttons.

Relevant Settings to Tweak: Unlocking Visual Potential

The OSD offers a surprising level of control over your monitor’s behavior. While not every setting will directly fix an HDMI problem, understanding their impact can help optimize your picture and troubleshoot potential conflicts.

Brightness and Contrast: Mastering the Basics

Brightness controls the overall luminance of the screen, while contrast affects the difference between the darkest and brightest parts of the image.

Adjusting these can improve visibility in different lighting conditions and correct washed-out or overly dark images.

Experiment with these settings to achieve a comfortable and visually pleasing picture.

Color Temperature: Finding Your Perfect Hue

Color temperature determines the overall warmth or coolness of the display. Lower temperatures (e.g., "Warm") produce a reddish tint, while higher temperatures (e.g., "Cool") produce a bluish tint.

"Normal" or "Standard" is usually the default, but experiment with different settings to see what you prefer.

Sometimes, an incorrect color temperature can make an image look unnatural, so adjusting it can enhance the viewing experience.

Input Source: Ensuring Proper Connection

This setting is crucial. The OSD’s input source setting specifies which input the monitor is actively displaying, such as HDMI1, HDMI2, DisplayPort, or VGA.

If you’re getting a "No Signal" error despite the HDMI cable being connected, double-check that the monitor is set to the correct HDMI input. Accidentally having the monitor set to VGA when you’re using HDMI is a common mistake.

Cycle through the available inputs until you find the one connected to your computer.

Response Time/Overdrive: Reducing Motion Blur

Some monitors offer response time or overdrive settings, which aim to reduce motion blur in fast-paced content, like games.

These settings work by speeding up the pixel transition time. However, setting it too high can cause "overshoot," which creates visible artifacts or ghosting.

Experiment with these settings to find a balance between reducing blur and avoiding unwanted artifacts.

Sharpness: Balancing Clarity and Artifacts

The sharpness setting adjusts the clarity of edges and details in the image.

Increasing sharpness can make the picture look more defined, but setting it too high can introduce unwanted artifacts and make the image look artificial.

Lowering it can soften the image. Find the sweet spot for balanced visual fidelity.

Eco Mode/Dynamic Contrast: Adapting to Content

Many modern monitors have "Eco" modes that automatically adjust brightness to save energy.

Similarly, dynamic contrast modes automatically adjust the contrast ratio based on the content displayed. While these modes can be useful, they can sometimes interfere with the image quality.

Try disabling these modes to see if it resolves any issues.

By carefully exploring and adjusting the settings within your monitor’s OSD, you can fine-tune your display for optimal performance and potentially resolve HDMI-related visual glitches. Remember, patience and experimentation are key to unlocking the full potential of your monitor.
