Question Samsung monitor aspect ratio broken

[Aaronstrong]

My samsung monitor’s aspect ratio is broken and I don’t know how to fix it. I didn’t change any settings or anything.
Here’s some photos of my problem and information about my monitor:

set the resolution to 2560x1440 via windows display settings or the GPU driver

set the resolution to 2560x1440 via windows display settings or the GPU driver

Windows settings and GeForce settings said that the resolution was 2560x1440 but now it works if my monitor is limited to only 144 hz. If I change it to 240 hz it breaks again

might be because of the 2nd monitor, reduce the resolution on the other monitor

Nvidia control panel says that my monitor doesn’t support it and doesn’t allow me to change to it. It also didn’t work when I unplugged my second monitor from the pc

which gpu is ?
reinstall the driver from Nvidia.com
eventually use ddu uninstaller if a fresh install doesn't work
try different DP port of your gpu, try the other dp port of your monitor
try a different DP cable
be sure the cable is firmly plugged in

I have 2070 super and I had no luck with those fixes. Maybe my GPU has come end of it’s life, because this hasn’t happened until yesterday. Everything else works just fine apart from the 240 hz refresh rate

maybe the monitor has a problem
