Resolution bugs after alt tab

[🔥✪OniCs🔥]

I have 1440x1080 4:3 custom streched resolution on cs2.
I play on a laptop connected to a monitor with hdmi.
After i alt tab, the 1440x1080 isn't stretched anymore, i have black bars. Doesn anyone know why?
Monitor: Samsung Odysey G4 LS25BG400EEXXS

Basicly if i want to alt tab i have to exit and reenter the game everytime.

Yes, happened sometimes. Not every time, when I'm alt-tabing, but like 1 in 5. It's common problem, nothing to do with your laptop or monitor.

I just noticed something, if i alt tab back using alt+tab, it's streched, but if i get back on cs by clicking the game on the taskbar i have black bars, really weird.

I didnt have this issue on my old monitor, just switched it yesterday.
