Manjaro KDE resolution stretching

I have a question regarding changing resolutions in manjaro, so I want to play CSGO in 800x600 stretched without blackbars but I dont know a way to make 800x600 stretched on my manjaro KDE if anyone has any idea please help me

Hello :slightly_smiling_face: !
Basically, you’ll just need to set your screen resolution to 800x600 in Manjaro. Whether this resolution is stretched or not will most likely be configurable in your Monitor’s OSD/Settings, the Operating System has very little influence on stretiching as far as I’m concerned.
Could you post the output of

xrandr

and

inxi -Fxza

when you run these commands in a Terminal?
