Hello, i see banding in all apps that have gradient, i had 8bit+frc display and though it was the issue, but now i have 10bit display and there's no difference, 10bit turned on in nvidia settings and windows display settings shows it like 10bit, but it doesn't look like it, tried different cables too, i don't see banding on other pc's, don't know what's wrong with this one.
Could you help me find what causing this?

    Hi @Andrew, 

    Welcome to Microsoft Q&A forum. 

    I understand that you are experiencing unexpected color banding in applications with gradients, despite having a 10-bit capable display and the correct settings enabled in both Windows 11 and your NVIDIA Control Panel. 

    It appears that while the hardware is reporting a 10-bit signal, the software-level color processing may not be aligning perfectly with the display's output capabilities. This behavior is often related to how Windows manages color profiles or how the GPU prioritizes high-bandwidth signals.  

    To address this, please follow the troubleshooting steps outlined below: 

    1. Adjust Auto Color Management (ACM) 

    Windows 11 introduced a feature called "Auto Color Management" to help apps provide accurate colors. In some configurations, this can impact how gradients are rendered. 

    • Go to Settings > System > Display > Advanced display. 
    • Select your 10-bit monitor. 
    • Locate the option Automatically manage color for apps and toggle it Off. If it is already off, try toggling it On to see if the rendering pipeline refreshes. 

    2. Verify NVIDIA Dynamic Range 

    The GPU might be defaulting to a "Limited" output range, which reduces the number of available color steps. 

    • Open the NVIDIA Control Panel. 
    • Navigate to Display > Change resolution. 
    • Under "Apply the following settings," ensure Output dynamic range is set to Full. 
    • Verify that Output color depth is strictly set to 10 bpc and Output color format is RGB. 

    3. Clear Existing ICC Profiles 

    If an older or incompatible color profile is active, it may be forcing an 8-bit color curve onto your 10-bit output. 

    • Search for Color Management in the Start menu and open it. 
    • Select your display from the dropdown. 
    • Check Use my settings for this device. 
    • If any profiles are listed, please Remove them to allow Windows to use the hardware default. 

    For a deeper look into how Windows 11 handles advanced color and the requirements for high-bit-depth displays, please refer to this official documentation: Change display brightness and color in Windows

    Please try these adjustments and let me know the outcome. If the banding persists, I would be happy to investigate further.

    It sounds like you're experiencing issues with color depth and banding despite having a 10-bit display. Here are a few potential causes and solutions to consider:

    1. Check Color Management Settings: Ensure that your system's color management settings are configured correctly. Windows has automatic system color management that can help ensure accurate color reproduction across devices. Make sure that this feature is enabled.
    2. Graphics Driver: Ensure that your graphics drivers are up to date. Sometimes, outdated drivers can lead to issues with color depth and display settings.
    3. Display Settings: Double-check your display settings in Windows to confirm that the bit depth is set to 10-bit. You can do this by right-clicking on the desktop, selecting Display settings, and then checking the Advanced display settings.
    4. Cable Quality: While you've mentioned trying different cables, ensure that you are using high-quality cables that support 10-bit color depth. For HDMI, ensure you are using a high-speed HDMI cable, and for DisplayPort, ensure it is a version that supports 10-bit color.
    5. Monitor Settings: Some monitors have settings that can affect color depth and display quality. Check your monitor's settings menu to see if there are any options related to color depth or color profiles that might need adjustment.
    6. Test Different Resolutions: Sometimes, the resolution can affect how gradients are displayed. Try adjusting the resolution to see if it makes a difference in the appearance of gradients.

    If the problem persists after trying these steps, there may be an underlying issue with the display hardware or compatibility with the graphics card.
