7870 tearing issues

This is an area I have little experience in so any help or guidance would be greatly appreciated.

I am trying to resolve tearing issues in video playback. I have not had a chance to try any games to see if it is an issue there as well.

I have a HD 7870with dual monitors. One is a new 23" Asus VH236H connect via HDMI. Other monitor is an old 19" Acer X192W. I have little understanding how to resolve the tearing issue and am not really even certain what the correct questions to ask are. Any help is appreciated.

  1. Very odd have you tried to isolate the problem maybe trying 1 monitor at a time and seeing if the playback tearing persists that is quite odd. Also, what do you use for playback. I use powerdvd myself best blu ray support I feel :)
  2. In process of further diagnosing. The 19 inch monitor never experienced this problem before so I am assuming this is a matter of video card tweaking. I did just try a 1080 rip of an action scene and it played smoothly so I am thinking its a matter of adjusting for odd sized video. I generally use VLC and WMP for playback and the issue seems to be independent of the playback software.
  3. Gotcha yea it was good that you narrowed it down to a screen yea I had a feeling since you had different screens that would of been my first guess.
  4. I think it was an issue with GPU scaling being improperly set and greyed out in ATI controls. Found a workaround and it is much, much better.
  5. Are you running Windows XP?

    If you are NOT, then:
    1. Test with only ONE monitor hooked up.
    2. Test with HDMI and also DVI.
