[quote]Sorry, I guess I wasn't clear. I didn't say "reference", I said "referenced". Specifically, I have this HD7970-DC2-3GD5 card.
Excuse me, I didn't catch that. Well, if you have tearing, then it must be either;
1. Plugged in the monitors wrong;
2. Somehow drivers are wrong;
3. A defect card (probably the clock generator).
If it's the first case it's easy; with this card you need to hook up all three monitors on the Displayports. You can't mix the DVI outputs with the Displayports (not even with adapters) because that causes tearing.
If it's the second case; you need to make sure you have the correct drivers. AMD has released
special drivers for the 7900 series, you need to download those. If the problem still occurs, clear the harddrive and do a clean install to make sure any previous drivers aren't screwing up.
If it's the third case; good luck. I have no idea how to prove that your card's hardware is actually broken, so I suggest you send it back to the shop and let it get tested there.

PS: Could you tell me what monitors you use? There are users here that have native DVI monitors mixed up with native DP monitors, connected to their cards without adapters, and experience no tearing.
I have a Dell U2410 as my center monitor (the one experiencing tearing), and two Dell U2412M monitors on the sides. All three monitors are connected by displayport, no adapters or converters. Just ordinary displayport cables right from the card to the monitors.
I don't have the driver you listed installed, when I installed the card I simply got the latest driver from AMD (cat 12.4) and installed that. When I get home I'll try those drivers, and maybe try switching the monitors around to see if its' a particular port on the card that's giving me issues.
