ok so i spent about 5 hours now reading 10000 posts about this problem but nothing worked for me.i am not trying that thing with card bios change, for reasons.

setup:
1. amd hd6850, ccc 12.8. stock clocks
2. syncmaster 20" 1680*1050 @ 60hz - DVI - primary
3. syncmaster 24" 1080p @ 60hz - HDMI - extended desktop - 7m cable (22ft)
4. win7
5. vlc player
everything is up to date.
i checked monitor hertz in windows, in ccc and in menu on monitors and its the same 60hz
movies run in 24fps.

i have had these dual monitors on my desk in dvi+dvi configuration and everything was ok.
i moved the 24" on a smaller table so i can watch movies in better comfort from my sofa and use my new speakers which i connected on the spot to the monitor.so hdmi was obvious choice.
but i still have this tearing in movies and dont know what to do :(

hope there is some new stuff to help.

ps: most of guys had same problem using dvi+hdmi so this may be the issue.
 
Try changing the video output to DirectX or OpenGL?
 
nope didnot help, opengl is the same, directx make it even worse (funny)

[Catalyst Control Center][preferences advanced view] select-My Digital Flat-Panels / select - Pixel Format [Select a pixel format for this display] select - RGB 4:4:4 Pixel Format PC Standard (Full RGB) and Apply

Are you sure that it is your hardware that is doing it? Could you be watching interlaced video with poor deinterlacing which could give you a jittery screen. Personally, I use Media Player Classic with these settings and it works pretty well. I'm also using dual monitors, one HDMI (DVI to HDMI adapter since I'm low on HDMI cables, the HDMI cable just gives me audio, I don't notice anything else with it) and one DVI. I don't think I've ever noticed tearing on a video before.

Hi

In regard to vlc player, I am uncertain what settings are causing the issue. I am with Aquinus +1; on this, I use Media Player Classic [MPC] however am unable to test this app with dual monitors at this time. It may be worth your while using MPC to *test; see if you are able to reproduce this issue and or it cures it.

http://mpc-hc.sourceforge.net/

Note: you may be able to set v-sync at driver level in catalyst control center and set a preset for the VLC app

nb: thanks for the screens

Edit:- Windows Extended displays; Double check that both monitors are set at the same refresh rate
Select: Screen resolution [from desktop] Select: Display 1 /Advanced settings/Monitor/Screen refresh rate; set to 60Herts
Select: Screen resolution [from desktop] Select: Display 2 /Advanced settings/Monitor/Screen refresh rate; set to 60Herts

Glad to hear it, if you're all set you reserve the right to close threads that you start.

Cheers! :toast:
