Full screen Video

Dell Laptop M60 with Quadro FX Go700 with lastest nvidia driver 81.84 Beta driver: When running full screen video in VMR mode. The screen will show a diagonal break up in the video frame. This is espacially happens at the high-rapid moving scenes.

This reuins the beauty of watching full screen videos.

Any resolution for that?

Thanks
 
You mean tearing? Try forcing Vertical Sync ("Wait for Vertical Refresh") on and enabling Triple Buffering for Direct3D.
 
Yeah... something like that... you may call it tearing! It is like a diagonal scisor cut of the frame.

I will try that.
 
If I use overlay and not VMR. all video will not show up in any player... Why so? ... I have no clue. why the overlay functions are not working?
 
For that you can try enabling "theater mode" (somewhere in the same place as vertical sync options. (graphics card control panel)).
Are you using dual monitors or anything other than just one monitor like TV out?
 
No now, but at work I do dual head mode. Now, I do not. Also, with lastest driver I lost the ability to swap primary to secondary monitors in dual mode, but this is another issue.
 
What media player are you using? Do all Overlay players fail like this, and similarly all VMR mode players have this tearing?
 
That is correct for both statements. I used real player, media player, VideoLAN, and Media Player classic.

Click to expand...

 
In MPC options, try Playback-->Output with the following options:

VMR9 (windowed)
Use regular offscreen plain surfaces
(enable) Lock back-buffer before presenting.

You are forcing VSync and not just "application preference", right?
 
First if all, with those settings, MPC is fxed... How about other players?
Yes, I am using force VSync.

Thanks a lot of your help.
 
Hmm...you'll have to do process of elimination here. My guess is the backbuffer lock. It's unlikely all applications would introduce some kind of artifacts in renderless mode (where they have full control of the display). Unfortunately, I don't think any of the other players you listed have that option. 🙁 That must be different than VSync. Either that or the force VSync is not working for some reason (not your fault).

When the problem happens, the video looks shifted (virtual divider line) or there is literally some line going through the video?

Worst case scenario MPC can be a decent substitute for Real Player and Quicktime Alternative (or anything that WMP or VideoLAN can play).
 
No not a vertical line. It is a diagnoal line, as if the one portion of the frame is displayed a slpit second berfore the second half.

Note: MPC has a problem with low volume for AC3 Audio Tracks rendered for a stero 2-channel output. This renders the MPC player usesless when playing video with AC3 track rendered for a stereo output.

 
For the AC3 problem, try MPC options->Filters. You will see two list boxes at the right. Uncheck DTS/AC3 on the left and AC3 on the right. Also try messing with AC3 decoder settings in Audio Decoders (but this only applies when the built-in AC3 filter is enabled, so if you did what I just said above ths sentence, this wouldn't apply).
 
Any ideas why, Overlay mode does not work? I tried videoLAN when VMR is disabled in the control panel and no video output.
 
Man... MPC with standalone AC3 filter is the best so far... why VideoLAN does not have such tweaking features?!! Only the MPC is working fine. Wy the AC3 filter is not linked in VideoLAN?
