Title: Tearing artifact when video scenes change
Post by: Z0001 on April 02, 2012, 06:45:06 am

Hi

I have been noticing a strange tearing effect at the bottom of the screen when watching Contagion, it only happens when the scene changes and appears as a lag in the scene change which has the effect of a slight flash. Also noticed that from time to time the bottom sixth of the picture in the same location was slightly offset from the rest, akin to a tear. Blu ray disc iso, RO HQ, i7 pc, hdmi to HDTV, most recent stable MC, 24p playback.

Any pointers?
Cheers
Z

Exact same problem here. So frustrating !
Altough this happens with any media player (VLC, WMP, etc.), so I think MC is not the issue in my case.

Tried different solutions to fix the problem without any succes yet.

Set up: .mkv file --­­­ i7 PC with Radeon HD 6670 -- 3 HDMI cables + interconnects -- SAMSUNG UND556300 HDTV.

I connected my PC monitor at the end of the HDMI cables and the video playback was flawless. Weird. Maybe my HDTV is the issue.

If any of you have logmein installed, one of the graphics drivers it installs shows as a video card. Disabling this device often fixes tearing problems, but doesn't interfere with the running of logmein.
Also, the first and obvious answer is to make sure your graphics drivers - Ati, Intel, nVidia - are up to date.

There is no LogMeIn on my PC.

My ATI drivers are up to date. Not sure about the Intel ones, though. Will definitely check this out.

Thanks for the suggestion !

No logmein, but I do have Splashtop and RealVNC, could there be problems there? AMD HD6870 drivers up to date a end 2011, so will look at those, no on-board graphics.

TMT5 works perfectly without this tearing.

Which Operating System do you use? Win 7 or Win XP?

In another forum I read that a change from Win XP to Win 7 solved the tearing problem through the AERO function of Win 7.

I've found a workaround to my problem.

In my case, it seems that the issue is caused by the use of two monitors:
PC Samsung SyncMaster (DVI) and Samsung HDTV (HDMI).

In the Catalyst Control Center (or whatever name AMD is using now), I simply selected  ''Make prefered'' for my HDTV which completely eliminated the tearing artifacts on the HDTV. Video playback is now super smooth in MC !

On the other hand, these artifacts are now showing up on my desktop monitor. It doesn't bother me too much since I watch most of my videos on HDTV. I can still switch for ''Make prefered -- PC monitor'' if I want a clean display on PC monitor.

Not an elegant solution but it works for now !

Fine, it works as workaround.

There I will come from Win XP for my first steps with JRiver I am interested in the question whether Win XP is suitable for JRiver according to ROHQ.
