Hey @Ioannis_Pantelakis,

Thanks for writing in! Here are a few additional troubleshooting steps for you to try:

Adjust Display Scaling on Windows:

  • Right-click on the desktop and select Display settings
  • Scroll down to Scale and layout
  • If scaling is set above 100%, try lowering it to 100%
  • Restart Roon and see if the issue persists

Manually Set the Display Resolution

  • Go to Display settings
  • Ensure the resolution is set to 3840x2160 (4K) or a lower 16:9 resolution
  • If it’s set to a custom resolution, try switching to a standard resolution

Update GPU Drivers

  • Check for any pending Windows Updates
  • Manually update NVIDIA/AMD/Intel graphics drivers via their respective websites

Disable High DPI Scaling for Roon

  • Right-click on the Roon shortcut
  • Select Properties > Compatibility
  • Click Change high DPI settings
  • Under High DPI scaling override, check Override high DPI scaling behavior and set it to System (Enhanced)
  • Click OK and apply changes

Try a Different Connection Method

  • If using HDMI, try a different HDMI port or cable
  • Test if connecting the PC directly to the TV (instead of through an AV receiver) changes the behavior

Reset Roon’s Display Settings

  • If none of the above work, try resetting Roon’s UI settings by renaming the “gfx” folder in Roon’s database:
    1. Close Roon
    2. Navigate to:
    • Windows: C:\Users\[Your Username]\AppData\Local\Roon\Database\Registry\Client
    1. Rename the “gfx” folder to “gfx_old”
    2. Restart Roon

Let me know if any of the above help! :raised_hands:
