GTX 680 Stuttery HD Playback

[chr6]

Just wondering if anyone else is experiencing this issue, first, let me tell you a bit about my desk:

GTX 680
3 Displays:
-Asus VS248H-P (Connected via DVI)
-Asus VS248H-P (Connected via DVI to DVI->DisplayPort Adapter)
-Samsung UN40D5500 (Connected via HDMI to DVI cable)

I typically game on the center display (Samsung) in windowed, full screen mode, while watching movies and such on either of the secondary (Asus) monitors. The issue I am experiencing is some sort of lag/choppiness when watching HD (1080p) content on either of the Asus displays. Some strange findings:

-I was able to resolve the issue by unplugging on of the displays (choppiness seems to go away when I run on only two monitors versus three).

-I have tried using different media players (VLC 1.1, 2.0, WMP), the issue exists across multiple players.

-I am using the latest Nvidia drivers (Windows 7, 64-bit).

-By moving the cables around, I can reproduce the issue on each individual monitor (note that this issue only happens on 1 monitor at a time; ie if its happening on one, it does not happen on the others).

My thoughts:

This may be caused to the type of cables I am using. I am thinking to just use straight DVI cables from the Asus displays to the GTX 680, and a straight HDMI cable from the Samsung to the GTX 680.

I did not experience this issue on my previous card (XFX 6970). Before I return the GTX 680, are there any other troubleshooting steps you can think of? Is there a setting within the Nvidia control panel that I have overlooked? I appreciate any input. Thank you.

I am guessing you didn't get the old AMD drivers out and that can be a PITA to work with...

I did use driver cleaner, and I've also re-installed the driver. At the moment it is working better within Media Player Classic by enabling GPU acceleration in the player settings. Thanks for the reply.

My experience is that 99% of the time its just better to bite the bullet and re-install windows. I've had weird issues going between amd/nvidia and vice versa, you can try driver sweeper though to remove any legacy files lingering around.

Did you install media codec pack?
Did you enable/disable GPU acceleration in VLC to see it it helps?

Pay attention to the refresh rates. The samsung might not have the same timings as the Asus and sometimes this causes pull down issues. You said it only happens when 3/3 monitors are plugged in, does it happen if you have just 1 Asus and the Samsung plugged in? Also what is the FPS of the video?

I installed CCC using Media Player Classic.
I have tried both enabling and disabling GPU acceleration in VLC, and I am seeing the same issue.

Understood, before I left for work this morning, I had messed around setting the two Asus monitors setting them to 1080p @ 59hz to see if it would make a difference, I didn't get to test, but that's my next step.

The issue does NOT happen when having just 1 Asus and the Samsung plugged in. Also, very interesting: if I set the Asus as the Primary monitor, then the problem goes away, (normally the Samsung is set as Primary), but If I set either of the Asus as Primary, the problem goes away.

Appreciate the ideas and troubleshooting steps.

This is my concern. Plug both of the ASUS monitors using only DVI->DVI cables and the Samsung using a straight HDMI to HDMI with no conversions going on.

It may only take 1 bad cable / conversion to cause some trouble. What make / brand of GTX 680 did you get?

Thanks nenforcer, really appreciate the feedback. I am trying to solve the issue without replacing cables first; I have the Asus GTX 680.

I'm still testing, but tonight it's looking really solid, and the fix was within VLC media player itself. I have turned on "always on top" by default, and all the 1080p content I've been watching is smooth and not jittery. I have no idea why or how this option fixes my problem, but it seemed to help alot. If the problem re-occurs I will probably use the straight cables as you suggested.

try K-Lite Codec Pack 8.6.4 and media player that comes with it.
