5870 cant handle dual screen?

[ilogik]

I started this thread http://forums.anandtech.com/showthread.php?t=2049637

I run dual monitors and I tried to play WoW and watch bluray on second screen and my system froze.

So I reformated and tried again, well it froze again. If I dont run WoW on one screen and watch a movie everything is fine but as soon as I try to run WoW my system freezes randomly. The interesting thing is that it will freeze at any point into many movies I have tried, all disk are perfectly clean and have not had any problems before.

Any thoughts?

The drivers can't handle it, that's for sure.

I think 1 screen has to be windowed . I never tried that before. My kids are watching TV, so I cant test it.

try maximized fullscreen and then do your vid

I re-installed again and this time I did not select their audio driver. It did not fix my cursor freezing every few seconds and the movies still stutters. Frankly I dont want to re-install again. I tried playing to movies in different programs with the same result. Anything else I can try?

I am running I7 940 on windows 7 64 bit legit.

Actually the blu ray just freezes randomly now, I cant even watch a movie. I tried different discs which I had no problem before, is this unique to 2 display setups? Its a fresh windows7 install....

Are you overclocking your card at all? I've had my system lock using ATI and dual screens, but it is related to my clocks on my card. Default is fine, o/c'd no go.

I could be wrong, but it sounds like your blueray player/drive could be at fault here. Do you have another one you could test out?

hm depends on if his graphics card is doing any acceleration. OP should get MPC HC and turn off EDR or VRM or whatever and just do basic CPU rendering and see if system locks up.

or try ripping the bluray first and playing the file. That way you can at least eliminate the drive as the potential problem.

1) are you correctly powering you video card?

if you are im gonna go with it being the drive and not the drivers, the card has more then enough power to do it. I tested this on my comp, i run a E8400 @ 4GHz with a GTX 285 and can run wow & play a BR movie at full screen running dual 1920*1200

I've just verified a similar issue myself. I played a 1080p movie (.m2ts, avg. 33 Mbps) using MPC-HC, and started playing Crysis in windowed mode @1920x1200. Nothing happened for 10 mins or so. Then I fired up Street Fighter 4 (again, windowed @1920x1200) and watched some replays.. then voila! My first encounter w/ GSOD. System froze for a few secs before it recovered. HD 5870 on an HP LP3065.

Maybe this is related to ATI's 2d acceleration problem with their new 5xxx cards. Just saw this on Toms Hardware that the new cards have problems accelerating 2d content when aero is active in Windows 7. Thus maybe playing a more 2d game like SF 4 causes problems while playing a movie compared to Crysis which is 3d.

I'll add that I play games while watching video on the 2nd monitor all the time. SF4 is not a 2d game btw. Once you are rendering poly's, you're rendering poly's.. doesn't matter that it 'feels' 2d.

I agree with the earlier poster who suggested trying Windows Media Player Classic and disabling the EVR GPU accelerated rendering output (off by default I think)..

I generally watch my videos with GPU acceleration off anyway because it seems to make sense to use the extra CPU core's cycles instead of stealing GPU cycles from my game.. so maybe I've unwittingly avoided this issue, though I'm pretty sure I've done it both on and off without probs. I'll try it with GPU acceleration on tonight to make sure and see how it goes.

one might-could test this by changing the setting in MPC-HC to 3D, or changing it around in general.

I am not overclocking anything in my system, later today I will try to run a single monitor and see if the movies still freeze.
