# Ubuntu – Ubuntu 18.04 external full HD monitor flicker

I had an issue with my external HD monitor which started flickering and the rows of pixels were unaligned with each other a bit so the picture was kind of blurry. I tried everything from changing some settings to a different kernel and nothing worked.

• Finally a simple change of resolution from 1920 x 1080i to 1920 x 1080 (at Settings - Devices - Displays - [choose the problematic display] Resolution) worked.
