Crossfire setup losing signal

post #1 of 7
Thread Starter 
Hey! First timer here, just built my first computer smile.gifsmile.gif

With my Sapphire 6950 Toxic GPU, I was able to play a video game on my 23" HP monitor (Using the DVI port) while sending the same exact feed to my 40" Sony mounted on the wall (Using HDMI).

In CCC, I had enabled my Sony TV as a duplicate display. On occasion I would extend to the HDTV instead by switching it up.

I like this setup because my friends love to watch DotA and Starcraft. Also it's easy to manage everything from a desktop, then turn and watch on my television.

THE ISSUE:

Everything was dandy until I got a second 6950 Toxic and enabled crossfire in CCC.

With crossfire enabled, I start the game I want to play and immediately my television loses its signal. If I turn off crossfire, everything works. What is going on here?

For starters, The DVI cable and the HDMI cable are plugged into the master card.

It only happens in games. To name a few, borderlands and warcraft 3. When I exit the game, the television receives signal again. The only fix I've really come across is buying a splitter - but that seems relatively silly for such a trivial task. I mean come on.

Thanks so much for your time smile.gif

EDIT: Sorry for generic headliner, I forgot to update it before posting my final post.

maybe an eyefinity setting that got turned on after crossfiring. Then the second signal stops because the games don't support eyefinity. you might be able to tell CCC to mirror displays.

Yes the bridge is on.

My HP monitor is my primary display. My TV is just a mirrored screen for HTPC usage and watching DotA matches.


It's like when I'm playing something that requires 3D games or anything, the mirrored port (HDMI) is completely shut off from sending signal. My home theater system doesn't even play sound like it normally does.

Okay I did do that and it allow the television to display the game instead of the monitor which is definitely a step forward...

But it still disabled my monitor and would not allow 2 instances of the game to be up.

Use ALT + TAB to bring the second monitor back. This happens when the games are not using the native monitor resolution of the primary display and has different aspect ratio, refresh rate and resolution from the second monitor.
