Monitor refreshing on sapphire 4870x2

[Kenjiwing]

Ive been a long reader of this forums and recently have been having some problems with my gfx card.

My setup is
Intel 80gbSSD
12gb corsair dom memory
i7 920
asus p6t deluxe
800 wat psu
sapphire 4870x2

since i purchased the 4870x2 i have been having a problem with it once i open up world of warcraft (I have not tested other games as this is the only real game I play).


I play WoW @ 1920x1200 with everything @ max settings. The refresh rate comes up @ blank but the options are 60 and 75.. my monitor is a DELL 2407FWP (http://accessories.us.dell.com/sna/products/Monitors/productdetail.aspx?c=us&l=en&cs=19&sku=320-6272).

The problem I am having is while wow is loading (i can be tabbed in or tabbed out to the desktop) my screen will constantly (the time is very random it can go minutes at a time without happening and then it can happen 3 times in a minute) flash black like the monitor lost its video signal it will then reset and come back.. this can last a couple of seconds but always comes back.. the problem is this has become rather annoying.

Does anyone have any type of suggestion to fix this problem?

There is an interesting thread here which might be related to your problem.

There is also this from the ATi forum.

The two threads make me think the problem is two-fold: for whatever reason, the video card is trying to switch to 1080i, and your monitor does not have a de-interlacer so it can't display 1080i. The solution is going to be to prevent attempts to switch to 1080i. I'm not clear on the best solution for that but there are hints in the threads I link to.

another thing is this did not happen when I had 2 4870s.. it only started happening once i replaced it with the x2.
