I have a Dell S2716DG 1440p Monitor with G-Sync and a 1080 ti. It is running the latest Windows 10 Creators Update.
I noticed earlier today that the screen is not totally being used. There are about 20-40 pixels on the top, left, right, and about 10px on the bottom that are not used.
It looks like this (stackoverflow will not load the properly rotated photo):
The resolution is set to native in Nvidia Experience, (2560x1440) but when I change the resolution, rather than making everything bigger but keeping the scale of the monitor, it actually uses less of the monitor itself.
Here's what that looks like:
I have restored the monitor to factory settings and this did not resolve the issue.
I have reinstalled the Nvidia driver (v381.65). This did not work.
I have enabled "Resize the desktop" in the Nvidia Control Panel and the tool would not let me expand the screen beyond the bounds.
I have changed the Aspect Ratio in Nvidia Control Panel from Aspect Ratio (default) to Fullscreen, and then no scaling. These did not resolve the issue.
How do I fix this?
