External monitor issue

I’m using the Endevour OS on my laptop today was the day when i conected widescreen monitor with hdmi. Interestingly it doesn’t run at full resolution but only at 1080 and it stutters and delays a lot. I have not encountered this before, can someone help me to solve the problem? Thank you very much !
