How to Fix Color Banding and Washed-Out Colors on a Monitor 2026 Guide

Nothing kills the vibe of a new monitor faster than looking at a sunset wallpaper and seeing ugly staircase stripes where the sky should blend smoothly. If your screen shows visible bands in gradients or your colors look like someone draped a gray sheet over them, you are dealing with two of the most common display problems out there. The good news is that most cases are fixable without buying new hardware.

Our team has spent years troubleshooting monitor color problems across gaming rigs, photo editing workstations, and budget office setups. In this guide, I will walk you through exactly how to fix color banding and washed-out colors on a monitor, covering every cause from wrong RGB range settings to outdated graphics drivers. Whether you are on Windows or macOS, using NVIDIA, AMD, or Intel graphics, the solutions below will help you get your display showing colors the way they were meant to look.

What Is Color Banding?

Color banding is a display issue where smooth color gradients appear as visible, stepped bands instead of seamless transitions. Picture a sunset where the orange should blend gradually into purple. Instead of a smooth fade, you see distinct stripes or blocks of color stacked on top of each other. That banding effect is what we are talking about.

The root cause almost always comes down to color depth, also called bit depth. An 8-bit panel can display about 16.7 million colors, while a 10-bit panel handles over 1 billion. When a monitor or graphics card cannot produce enough intermediate shades between two colors, it rounds them off, and those rounded gaps become visible bands. Budget monitors sometimes use 6-bit panels with FRC (frame rate control) dithering to simulate 8-bit output, which can make banding even more noticeable in certain content.

Color banding is different from dead pixels, backlight bleeding, or screen burn-in. It specifically affects gradient smoothness and does not show up as spots or patches. Instead, it shows up as hard lines or steps where a gradient should flow.

What Causes Color Banding on a Monitor

Understanding the cause is half the battle. Color banding can come from hardware limitations, software misconfigurations, or connection issues. Here are the main culprits I see over and over again.

Low Bit Depth or Panel Limitations

If your monitor has a 6-bit or 6-bit+FRC panel, it physically cannot display as many colors as an 8-bit or 10-bit panel. No amount of software tweaking will add colors the hardware cannot produce. You can reduce the visibility of banding, but some level may always be present on budget panels.

Incorrect RGB Range Settings

This is the number one cause I see on forums like Reddit and Tom’s Hardware. Monitors and GPUs use two RGB ranges: Full RGB (0 to 255) and Limited RGB (16 to 235). If your GPU outputs Full RGB but your monitor expects Limited RGB, or vice versa, you get crushed blacks at the bottom and washed-out or banded gradients at the top. This mismatch is incredibly common when connecting via HDMI.

Outdated or Corrupted Graphics Drivers

Many users on r/Monitors and r/buildapc report that color banding appears after a driver update or a Windows update. Corrupted or mismatched graphics drivers can force your GPU into the wrong color depth or output format. If banding suddenly appears after an update, drivers are the first thing to check.

Wrong Color Depth in GPU Control Panel

Your GPU control panel lets you set the output color depth. If it is set to 8 bpc (bits per component) when your monitor and cable support 10 or 12 bpc, you lose gradient smoothness. This setting is often left at default and forgotten, even on capable displays.

Cable or Connection Bandwidth Issues

HDMI, DisplayPort, and USB-C all have different bandwidth limits. Running a high-resolution, high-refresh-rate display over a cable that cannot handle the bandwidth can force the GPU to drop color depth to compensate. I have seen users fix banding simply by switching from an old HDMI cable to a certified DisplayPort cable.

HDR and SDR Mismatch

If Windows HDR mode is turned on but your monitor is an SDR display, or if HDR is enabled but content is SDR, colors can look banded and washed out. HDR requires a 10-bit pipeline end to end. A single weak link in the chain introduces banding.

OLED-Specific Banding

OLED displays are not immune. Some OLED panels show near-black banding due to how they handle ultra-low brightness levels. This is sometimes called near-black crush and can look like banding in dark game scenes or movie letterbox bars.

What Causes Washed-Out Colors on a Monitor

Washed-out colors describe a display that looks faded, hazy, or lacking in saturation and contrast. Instead of deep blacks and vibrant colors, everything looks like it has a gray fog over it. The causes overlap with banding but have some unique triggers.

The most common cause is the same RGB range mismatch I mentioned above. When your GPU sends Limited RGB (16 to 235) to a monitor expecting Full RGB (0 to 255), everything below 16 becomes the same shade of dark gray and everything above 235 clips to white. The result is a flat, washed-out image with no true blacks.

Other causes include incorrect color space settings (forcing sRGB content into a wide gamut or vice versa), wrong gamma settings, a missing or corrupted ICC color profile, and brightness or contrast set too high on the monitor’s OSD (on-screen display). USB-C connections are notorious for causing washed-out colors on external monitors, often because the connection defaults to Limited RGB.

How to Fix Color Banding and Washed-Out Colors on a Monitor

Now for the part you came here for. Follow these steps in order. I have arranged them from easiest and most common fixes to more advanced troubleshooting. Most users will find their solution in the first three steps.

Step 1: Set the Correct RGB Range

This single fix resolves the majority of both banding and washed-out color issues. You need to make sure your GPU and monitor are both using the same RGB range, and for PC monitors, that range should almost always be Full RGB (0 to 255).

For NVIDIA users, right-click your desktop and open the NVIDIA Control Panel. Go to Display, then Change resolution. Under the color settings section, set Output dynamic range to Full. Set the output color depth to the highest available (10 bpc or 12 bpc if supported). Set the color output format to RGB.

For AMD users, open AMD Adrenalin and go to Gaming then Display. Set Pixel Format to RGB 4:4:4 Pixel Format PC Standard (Full RGB). For Intel users, open the Intel Graphics Command Panel and set the color range to Full.

After applying, check if banding is reduced and blacks look deeper. This one setting is the fix that forum users on r/pcmasterrace confirm over and over.

Step 2: Update or Reinstall Your Graphics Drivers

If banding appeared suddenly, especially after a Windows or driver update, a clean driver reinstall is your next move. Download the latest driver directly from NVIDIA, AMD, or Intel. Use DDU (Display Driver Uninstaller) in safe mode to completely remove the old driver, then install the fresh download.

This matters because old driver remnants can conflict with new installations and force wrong color depth settings. A clean install wipes those conflicts away. Many Tom’s Hardware forum members report that banding disappears entirely after a clean driver reinstall.

Step 3: Set the Correct Output Color Depth

Even with the right RGB range, your GPU might be outputting at 8 bpc when it could push 10 or 12 bpc. In the NVIDIA Control Panel, under Change resolution, look for Output color depth. If your monitor and cable support it, set this to 10 bpc or 12 bpc.

If the option is grayed out, it usually means your cable or monitor does not support higher color depths at your current resolution and refresh rate. Try lowering the refresh rate temporarily to see if higher color depth becomes available. If it does, your cable is the bottleneck.

Step 4: Check and Replace Your Cable

Cable quality matters more than most people think. A cheap or old HDMI cable might not carry enough bandwidth for high color depth at high resolutions. Try switching to a certified DisplayPort cable or an Ultra High Speed HDMI cable rated for your resolution.

I have seen cases where a user replaced a five-year-old HDMI cable with a new DisplayPort cable and eliminated banding instantly. The old cable was silently limiting color depth to maintain resolution and refresh rate.

Step 5: Disable or Properly Configure HDR

If your monitor is not HDR-certified, turn off Windows HDR. Go to Settings, System, Display, and toggle off Use HDR. Running HDR on a non-HDR display forces the GPU to compress a wide color gamut into a narrow SDR space, which creates banding.

If your monitor is HDR-certified, make sure HDR is enabled in both Windows and your monitor’s OSD. Also confirm that your content and the application you are using support HDR. Mismatched HDR settings are a frequent source of banding even on high-end displays.

Step 6: Adjust Monitor OSD Settings

Your monitor’s built-in menu has color settings that can cause or fix banding. Open the OSD using the buttons on your monitor and check the following. Set the color temperature to a neutral or custom setting around 6500K. Set the color gamut mode to match your usage, sRGB for general work or wide gamut for HDR content. Reset the gamma to default or 2.2.

Avoid cranking sharpness too high, as artificial sharpening can accentuate visible banding steps. Set brightness to a comfortable level, typically 120 to 200 nits for office work or higher for bright rooms.

Step 7: Calibrate Your Monitor

For the most accurate fix, use Windows Display Color Calibration. Search for “calibrate display color” in the Windows start menu and follow the wizard to adjust gamma, brightness, contrast, and color balance. This also generates or applies an ICC profile.

For professional work like photo or video editing, consider a hardware colorimeter like a Datacolor Spyder or X-Rite calibrator. These devices measure your screen’s actual output and create a precise ICC profile that corrects color and gradient issues at a level software calibration cannot match.

Step 8: Use the Safe Mode Diagnostic Test

This is a powerful diagnostic trick from the forums that most guides miss. Boot your PC into safe mode and look at a gradient test image. If banding disappears in safe mode but returns in normal mode, the problem is software related, likely a driver, GPU setting, or background application. If banding persists even in safe mode, the issue is either your cable, your monitor hardware, or the monitor’s internal processing.

This single test saves hours of guessing. It cleanly separates software causes from hardware causes and tells you exactly where to focus your effort.

How to Fix Washed-Out Colors Specifically

If your main problem is faded, gray-looking colors rather than banding steps, here are the targeted fixes that work best.

Fix 1: Force Full RGB on USB-C and HDMI Connections

USB-C and HDMI connections frequently default to Limited RGB, which is the leading cause of washed-out external monitors. Go into your GPU control panel and force Full RGB output as described in Step 1 above. This is especially important for laptop users connecting to external displays via USB-C docks.

Fix 2: Restore Your ICC Color Profile

Sometimes Windows loses or overwrites your monitor’s ICC profile, leaving you with a generic, flat color setup. Go to Color Management in the Windows Control Panel. Check the box to use your own settings for the device. Click Add and select your monitor’s profile if available, or apply a downloaded ICC profile for your specific monitor model.

Fix 3: Check the Monitor’s Color Space Setting

Some monitors have an OSD setting that forces a specific color space. If your monitor is locked into a wide gamut mode but you are viewing sRGB content, colors can look oversaturated on one end and washed out on the other. Set the monitor to sRGB mode for standard content, or auto mode if available.

Fix 4: Adjust Brightness and Contrast Properly

Contrast set too high crushes detail and makes colors look artificial. Contrast set too low makes everything look flat and washed. Start with contrast at 70 to 75 percent and brightness at a level comfortable for your room. Then fine-tune using a grayscale test image.

NVIDIA and AMD GPU Color Settings

Since GPU settings are the most common fix, here is a focused breakdown for both major GPU brands.

NVIDIA Control Panel Settings

Open NVIDIA Control Panel and navigate to Display then Change resolution. Scroll to the bottom section. Set Output color format to RGB. Set Output dynamic range to Full. Set Output color depth to 10 bpc or 12 bpc if available. Set Output color space to the matching setting for your monitor.

Then go to Adjust desktop color settings. Set the color adjustment method to NVIDIA settings. Set the color enhancement to Full, and set the gamma slider to 1.0 or leave at default unless you have a specific reason to change it.

AMD Adrenalin Settings

Open AMD Software Adrenalin Edition. Click the gear icon for Settings, then go to Display. Set Pixel Format to RGB 4:4:4 Pixel Format PC Standard for Full RGB. Enable Custom Color Temperature if needed and set it to 6500K. Adjust the color depth slider to the maximum supported by your setup.

For both NVIDIA and AMD, restart your PC after applying changes. Some color pipeline changes only take full effect after a clean reboot.

How to Test for Color Banding

Before and after applying fixes, you need a way to measure whether things improved. Here is how to test for color banding.

Use a free gradient test tool. The simplest option is to search for “color banding test gradient” and view a full-screen gradient image. Look for visible steps or stripes in what should be a smooth fade. If you see hard lines between color steps, you have banding.

For a more thorough test, use the free online gradient tool at pixeltest.net or the built-in test patterns in the Lagom LCD monitor test pages. These tools display precise gradient bars that make even subtle banding visible.

Compare your results before and after each fix. Take a photo of your screen with your phone at each stage so you can compare side by side. This makes it easy to see which fix actually moved the needle.

Expert Tips for Better Monitor Colors

On macOS, the color management system works differently than Windows. macOS applies color profiles automatically through ColorSync. If colors look off on a Mac, go to System Settings, Displays, and check that the correct profile is selected for your monitor. Also try disconnecting and reconnecting the display to force macOS to re-detect the correct color space.

For OLED monitor owners, near-black banding can be reduced by slightly raising the black floor. Set the OLED brightness one or two notches higher, or enable any black-stabilization feature in the OSD. This trades a small amount of true-black depth for smoother dark gradients.

Finally, give your eyes a break. Sometimes what looks like banding or washed-out colors is actually eye fatigue from staring at an overly bright screen for too long. Step away for ten minutes, then reassess with fresh eyes.

FAQ’s

Conclusion

Color banding and washed-out colors are frustrating, but they are rarely a reason to replace your monitor. In the vast majority of cases, the fix comes down to matching your RGB range between your GPU and display, updating drivers, using the right cable, and setting the correct color depth. The safe mode diagnostic test is your secret weapon for telling software issues apart from hardware problems.

If you have worked through every step in this guide on how to fix color banding and washed-out colors on a monitor and still see issues, the problem may be a cable failing or a panel with a low bit depth that no software tweak can fully overcome. At that point, upgrading to a monitor with a true 8-bit or 10-bit panel and a certified high-bandwidth cable is your next step toward color accuracy.
