I am running Fedora 35 Workstation with Gnome. Interestingly since upgrading to Fedora 35 the screen does not move all the way to the edges. There are black bands around the edges.
CPU: Intel i5 3570K
GPU: AMD RX 570
Monitor : LG 32QN600-B 31.5 inch model (QHD)
Sorry if this has already been solved, I couldnt find anything in the previous topics.

I have same experience in the past but with different brand. Maybe you could go to “Gnome Settings” and then on the display settings, try to toggle the “Adjust for TV” on or off.
You also may be able to adjust the settings on the monitor itself.
What is the output of xrandr? Does it show the proper resolution & scan rate for that monitor?
The monitor is specified at 2560x1440 @ 75 Hz refresh and for full screen display probably should show the same in xrandr.
thanks so much, it was switched “on” so I switched it “off” and then clicked “apply settings” and its now fixed !
However strangely it stayed switched on but is still fixed. So it did the trick, really grateful thanks a lot
Thats a good idea too, the “adjust for tv” switch seemed to work but I will keep that mind if it returns,
the output is below. my refresh rate is a bit high. it says correct resolution 2560 x 1440 which is the monitor resolution. I verified this with the monitor on screen display also and they match.
[solomon@fedora ~]$ xrandr

Actually that xrandr output shows the monitor in its preferred state. the monitor is designed for 2560x1440 @ 75. The * indicates the current refresh rate in use.
great thanks for explaining that, so how do we know if its the preferred state ? I guess check the specs of the monitor manufacturer right. does that command show the designed max resolution or the current setting?
In the xrandr output the line with the * shows the current setting.
If the marked value matches the device specs then everything is good.
