My monitor is fine when the resolution is low but if I try to increase it, the whole screen starts to shake. I don't have any mobiles or other devices around the desktop.

Also the software has been updated recently.

Can you help please?

Hmm... do you mean a physical shaking, or just the visuals on the screen?

If you know, could you please give us system info? (ie monitor brand, name, model computer brand, name, model)

It's a Lenovo Think Centre M57 Desktop PC.

Also it's the whole screen.
