Screen tearing on LG 3D HDTV when PC with Radeon HD 5870 is connected

So...I recently bought this TV: http://www.bestbuy.com/site/lg-47-34-class-46-9-10-34-diag--led-1080p-120hz-smart-3d-hdtv/7524079.p?id=1218849840540&skuid=7524079&sellerId=

Display looks great. I am running all my gaming systems including my PC on it. Only I've noticed that there is some screen tearing going on when my PC is connected to the TV. I am running my PC with a Radeon HD 5870. Can anybody give me some tips on how to get rid of the screen tearing? Its most noticeable when watching fast moving pictures (IE videos on netflix)

  1. did u install the latest drivers for your 5870?
  2. Um, I always keep my drivers up to date lol.
  3. vsync and tripe buffering
  4. How do I force that on Windows 7?
  5. I suppose you are getting screen tearing when playing games. Just enable vsync in the game's video/graphic settings.

    No, its not just when playing games.
  7. What cable are you using to connect it to the PC?

    The Problem with tearing on dualmonitor-setups is the issue with the timing clocks on radeon cards.

    You can use the 12.3 Catalyst driver , which hasnt got any Idle-Clocks.


    The advantage is, tearing is gone. The disadvantage is that your card will be running at a steady 775/1000-mode even when your PC is idling -> more power consumption + higher temperature.
