Video out put flickers

[newtothegrounds]

Hi to everyone, I'm having issues with my MSI 5850 OC. When ever I hook up a second display to it threw any of its video output ports on the second display device it flickers really bad along the bottom of the screen. I currently have it displayin to my 50" LG wich is 1920x1080. If i set my computer monitor to second display it will ficker an tear on that as well. If there is no second display I do not have problems, but soon as there is a second display device it tears and flickers along the bottom. I also have a BFG 9800GTX+OC if I hook both my display units up to it I dont run into any issues with tearing and flickering so I'm thinking its the ATi card. Any help would be great I'll post my system specs below. everything is running at stock speeds.


Case: Cooler Master HAF, Mobo: Evga 790i Ultra, CPU: Q6660, CPU Fan: Thermalright 120 ultra, PSU:1000watt Silverstone Strider, Vid:ATi MSI HD 5850 OC, BFG 9800GTX+OC, RAM: 6gigs-Corsair DDR3, HDD 4x1TB WD Green, 1xOCz SSD.

hmmm wait im confused are u running from 2 different cards?

[newtothegrounds]

Yes I usually use my 9800 for displaying to my TV, but recently switched to just running both my main display and TV both of my 5850. When ever theres a second device plugged into it that device gets really bad tearing and flickering along the bottom.

...i may be way of the mark here and living back in the stone age...but wont that be because the clocks on those 2 devices are so different?...

[117425]

and some 3d apps cant support to devices running 2 displays very well...at least back in the day?

[newtothegrounds]

It doesnt matter what app I'm running even at desktop it does it, both my TV and computer display are 1920x1080 60hz, and my second video card is in but no device is plugged into it. If I flip the cards around and use my 9800 to run both displays I dont run into any problems just when my ATi is doing it

[117425]

i have a sugestion to help id the problem...use watever ocing program u have to make the clocks as even as possable and leave all vertical sync.refresh features off...see wat happens

[newtothegrounds]

I'm currently at work but when I get home I will try it out and let you know

[117425]

ok cool...so basically make the clocks level...or as close to it as possable on both cards...the 9800gtx u have...thats not a duel gpu is it?

[newtothegrounds]

nope, but would my system even be using my 9800 for desktop drawing if its not even hooked up?

[117425]

so as in ur ati card and ur 9800gtx are plugged into ur mobo but only ati hooked up to a monitor...in that case no...is that wat u mean

[newtothegrounds]

bang on, my tv and monitor are hooked up to my ATi, and my nvidia is plugged in but not in use.

Try and lower the resolution on your 23" monitor to see if the problem persists. If it does, you may have a faulty card, and an RMA might fix the issue. If the problem goes away, it is simply the way that the 5850 handles surpassing the max resolution. How are you handling the conflicting drivers? Have you swept the nvidia drivers from your system?

[newtothegrounds]

the 5850 supports my resolution natively so I'm not surpasing its max resolution and I've had no driver issues or conflicks with the two cards aside from this one issue with dual display but it is card specific.

[nzaneb]

RMA the 5850

[newtothegrounds]

You think it really needs to be RMA'd? I run MW2 maxed out and mass effect 2 hrs on end and dont have any problems, even combbuster on burnin.

[sandyduff]

When you hook up the second display, do you always use the same port? If you swap the displays round, is it still always the second display that flickers?

[dgb303]

Try disabling the ATI Overdrive feature, and make sure drivers are up to date.

[nzaneb]

It could be the DVI port. Does it do it if you use the HDMI output as the second display?

[newtothegrounds]

Ive tried it on both DVI ports and the HDMI port with same results I'll try disabeling overdrive tonight, drivers are the newest one on ATi's website of three days ago.

I would try older drivers first (9.12s I believe are best for 5800 series from what I read)

Otherwise, RMA time. There is no reason for any problem with dual monitors, ATI has always been good at handling dual monitor setups.. back since my radeon 7000 at least.

I've seen this problem with early windows 7 builds, what os are you running?
I think it is most likely a driver issue. Either your system is having problems from having two different video drivers, or you need to use a different ati driver, try 9.12 if you haven't already. If all else fails RMA.

[newtothegrounds]

windows 7 ultimate 64bit oem (none beta actual release)

[Younglin]

windows 7 ultimate 64bit oem (none beta actual release)

Yeah like I said I've only seen the problem with the early releases of windows 7. ( usually the beta) What drivers have you tried?

[newtothegrounds]

Thanks for all the help guys I tried the older drivers 9.12 and it seems to have cleaned up the issue.
