What is HDMI Scaling? Connecting an HDMI display to AMD Graphics does not let the picture scale correctly to fit the display’s whole screen area. As a result, you can find the picture over-scanned or under-scanned. Hence, you should know that a picture is called under-scanned when it has a smaller size than the screen’s physical area. It creates a black border around the image.
On the other hand, a picture is called over-scanned when it expands beyond the screen’s physical area. You can’t see the picture portions which extend beyond the screen edge. People can use the HDMI Scaling option within Radeon Settings to troubleshoot the problem of overscan or underscan.
