Fullscreen video on my new 1080p monitor is choppy when it comes from my laptop. The same video plays when not full screen. This goes for all video(Flash/MKV, etc), regardless of video resolution.

I have an ATI Mobility Radeon HD 4200 Series card in my Thinkpad Edge, Turion X2 2GHz. The computer plays 1080p fine.

Things I've tried:

  • Updating Drivers
  • Switching cables
  • Turning Hardware Acceleration
  • Changing video players process priority
  • Rebooting
  • Turning of laptop screen
  • Turning off unused processes

Nothing Works. What is the likelyhood that my laptop cannot power a 1920x1280 display?

I have read that a similar issue like this for fullscreen video in VLC can be resolved by right clicking VLC.exe and then goto properties and look under the compatibility tab and check the box labeled: "Disable display scaling on high DPI settings"
