LCD Flicker

Looks like the lower portion of my LCD is trying to readjust its height.

This doesn't show up if I record the screen. It seems to only appear when displaying certain kinds of graphics... like the dark UIs of Blender and Adobe Illustrator. It also shows up if I play back a video of these troublesome GUIs in fullscreen!

What could be causing this?

EDIT: Fixed by moving the image up when the problem occurs. Moved image on screen to Vertical 49 instead of 50

It looks like your monitor is adjusting the screen to fit what it is being shown. It is probably a configuration problem. You should set it to "just scan" or whichever is the equivalent on your monitor.

  • Oh I've tried hitting Auto-adjust, and changing every other setting in the monitor's OSD, but it doesn't affect this problem. It's not global anyway, just the bottom 10% of the screen I'd say. – SouPress Jun 29 '15 at 16:42

    The problem is exactly the opposite. Your monitor is adjusting too much, this is why it gets confused with black screens. You should hit auto adjust on a full white screen and then set it off. What is happening is that your monitor is self adjusting to compensate slight error in over and underscanning. This is in fact a common issue. Changing the cable from HDMI or RGB to DVI might fix it. There are also some tinkering possible with your videocard driver (try to find the overscan/underscan settings) – user27221 Jun 29 '15 at 17:10
