Windows 10: Screen resolution acting up, quadruple duplicate overlapping display

https://i.imgur.com/fWb5UYf.jpegImage failed to upload here, so I had to upload it elsewhere When I started up my PC I was greeted by this screen artifact. Briefly upon starting up a box shows up saying "The screen is not currently set to the recommended resolution. Configure the PC resolution to 2560x1440. The 2560x1440 resolution may not be supported on some PCs. Current resolution: 2560x960." This box shows up correctly, by the way. The display is an LG 27GL83A-B UltraGear.While difficult to navigate, I did manage to open Settings to try some things, none of which work:-Changing the disp

Problem with resolutions on a duplicated display

Thanks Graeme but it sound like you're just stating the obvious: if the 2 displays run at the same resolution, then you can duplicate them with no changes of resolution.

My question is what is going on when the 2 displays are running at different resolutions? In my case, display 1 (PC) is running at a higher resolution (4K) than display 2 (DTV)'s FHD, but I can still duplicate display 1 on display 2. While I don't expect
display 2 to be running at 4K, why is it running at only HD? Seems like something is converting the 4K signal to HD and not to FHD.

Display 2 looks exactly like Display 1 except that everything, like text, looks fuzzier due to the HD resolution.

Under "Advanced display settings" for Display 2: DTV, it shows "Desktop resolution" at 3840x2160 but "Active signal resolution" at only 1280x720.

Is there some way to change the conversion ratio?
