Ideas?

[frosty]

I'm finding that if I play a video in windows media player, it plays just fine. But Vegas, Resolume, and Video Projection Tool all stutter and tear if you are displaying them on the second monitor. Also, the tearing only occurs if I output HDMI.

I'm downloading the very first driver that launched with the card to compare the two.

Having it narrowed down like that is good. Contact AMD with that information (along with everything else) and they'll be able to better analyze what about the driver is causing the problems and issue a custom driver for you if needed.

In the past, ATI was very much concerned with this kind of stuff, and as can be seen with most comparisons, their video decoding and quality is by far better than what NVidia offers.

So, if it works in WMP but not in others, it's either a hotfix by AMD, or WMP uses a different API for displaying video, compared to Vegas and whatnot. I tend to believe it's the latter.

What you could do to try this hypothesis is use VLC and try all the video output plugins there are. YUV, GDI, SDL, OGL, DX, D3D... ...

I'll do that, thanks for the suggestion. The driver downgrade didn't work, btw.

Which method of contact would you recommend? I can't seem to find any way to directly contact them on their support page.

WMP will tear on the second screen with certain videos as well. It's just not as prone to it. This really is ruining everything I bought this card to do. I'm putting the geforce back in until AMD gets their shit together.

So... it's a codec issue then...

So... it's a codec issue then...

Tried rendering the video to every codec in the book. It doesn't care which one, or even which resolution, they all stutter and eventually start tearing.

[Segitz]

Well... if WMP tears with just some videos, my assumption was that some videos use different codecs and thus tear. A computer is, usually, deterministic... meaning for each use case, it handles the situation the same. In videos, you could asssume, that the content (i.e. picture and audio) doesn't matter, only the way it is encoded.

The problem with your problem for me is, that I cannot replicate it. I don't have these issues at all. I use dual screen setups all the time from both my desktop at home and my laptop and uni. Both use an AMD card (the laptop is an Evergreen, the desktop is Northern Islands, same as yours). It seems to me, there's something within your DirectVideo or whatever in your system that interferes somehow. Currently, I can even state that screentearing in videos is even gone in Linux. And I had that issue for years on every card I owned previously, even Nvidia.

There's still some things left you could test. Get AMD Fusion software and set up a gaming profile, which disables all unused services, incl Aero, and disables lower clocks of your system.

He shouldn't have to change how he works to get the second monitor working.

[Segitz]

I am not asking him to change anything he does. In fact I couldn't even ask that, because I don't know how his work is done.

[frosty]

Still no reply from AMD. I'll try your recommendation segitz.

Direct3d issue maybe (even though it stutters and tears in opengl also), but it isn't a codec issue because I've tried every codec in the book and they all tear.

After reading around, a LOT of people have had this issue when running the card in OC mode. I'm not overclocking though. I just tried editing a video in Vegas and outputting the screen to my second monitor. It tore so badly it was unusable. 2 horizontal tears that sit about a third from the top and bottom of the screen. If I use Resolume or VPT6.0 to play back video, the video will stutter in frame rate and eventually a horizontal tear works it's way from the bottom of the screen upwards slowly.

This has completely ruined everything I bought this card to do. Video editing, video mapping... all worthless. I'm sticking to Nvidia from here on out. The last ATI card I bought I got rid of due to driver issues that they refused to solve. I decide to give them another chance and here we go again. I should have known better.

The AMD fusion thing made no difference at all.[COLOR="Black"]

[frosty]

OK, it's not the card. My old Geforce GT 450 is tearing on screen 2 as well. Recommendations?

And I solved the issue... Turns out it was just the... fucking theme???

[Viper]

PSU? PCI-e slot? HDMI cable? Monitor?

May want to check with the software vendors now and see if they have any suggestions.

WTF....the theme? Seriously?

[Segitz]

Remember me saying "try AMD fusion and disable AERO"?

[Viper]

Segitz, the problem was corrected when enabled Aero. Not disabled it.

[Segitz]

Whatevs^ As I said, I never had these problems in Windows... and without replicating it here... you know.

In any case, Windows is just as buggy as Linux is, although it has "better" drivers.

[Viper]

Can you turn off your Aero theme and see if you can replicate the problem?

[Coded-Dude]

are you getting any tearing with DVI?
