Fixing overscan issues

Overscan is a common issue with HDTVs, but there are some steps you can take to disable overscan:

  • Check the TV's settings and see if there is an option to disable overscan.
  • Use CRU to edit the affected detailed resolution and choose "CVT-RB standard" timing. This will use a different timing standard that some TVs will not overscan.
  • If you don't need HDMI audio, use CRU to delete the extension block, or edit the extension block and delete HDMI support. This will cause the GPU to send a DVI signal, which most TVs will not overscan. This will not work with 4K TVs.
  • Use the graphics driver's control panel to scale the image down. This will affect image quality.
