So i recently got given an all in one PC but im only using the HDMI for the 1080p. The actual PC im not using it, just the display. The only problem is that its not entirely covering the whole screen. There's like 1 inch of a black edge on all 4 sides and on this HDMI monitor the icons and desktop looks bit blurry as if they had a lower resolution, yet they are at 1080p 60 hertz. Any possible fixes?? Im also using AMD gpu.
