Display Refresh Rate and Sizing Issues

Papa P · February 16, 2021

Hi All,

Within the last 2 weeks I've been plagued with a problem where on boot my monitor will display in 1280x720 at 100hz but the image is not stretched across my monitor it's displaying that image in the center of the monitor and only using those pixels (see picture). On some restarts it will display 1920x1080 (like it's supposed to) but it then only runs at 100hz and wont go any higher. I've been able to temporarily fix it by only running 1 monitor and unplugging and then plugging the monitor in coupled with restarting my computer. This issue is now permanent when I run this 1920x1080 monitor with my 4k monitor. This morning I also started having the issue where when running 2 monitors my 1920 monitor would display a black screen then come back on and then repeat whenever I moved a window on either monitor.

System:
CPU: AMD 5800x

GPU: RTX 2080 with a minor overclock

Monitors: BenQ XL2420Z (1920x1080 1ms 144hz)

LG 27GN950-B (4k 1ms* 144hz)

DDU the drivers and then re-install the latest and see if that fixes it.

It's working for now. If it breaks again I'll be back.

It was working fine while under continued use. I went and ate dinner and came back to the screen turned off like it would be if I had the "Turn Screen Off after X time" function running (which I dont). When I hit a key on the mouse the display turned back on but once I stated opening windows the display cut to black, came back on it kept cutting to black if anything moved on the screen. I restarted my computer and was greeted by the 1280x720 small screen (same as the picture from the first post).

I have determined that my graphics card is probably starting to go bad since I switched it out with a 660 I had laying around and the problem hasn't come back.
