| Post subject: | Tearing |
I know, it's common problem for 6XXX series. On my 6970 I have the following connections for 3x1 eyefinity: DVI-DVI DVI-DVI DP-VGA So, what we have - 2 monitors should have no any tearing at all except third screen since it's using DP-VGA. But I'm getting tearing on the second screen with DVI-DVI connection too. Why do I get it? P.S. Is there any chance if 6970 Sapphire with their FLEX technology will avoid this problem? Thanks |

Tearing isn't only a problem for the 6xxx series, but for all video cards that don't have three identical outputs. So buying a card such as a FLEX from Sapphire should resolve you problem. But you are right, you shouldn’t have tearing on two monitors with your current setup. Please make sure that you set a monitor (usually the center one) that is connected via DVI->DVI to be your primary monitor in CCC. |

I have no idea why but i never had tearing on my 6970! Might be because i used DVI/DVI/DP nativ. |

I think it's when not all 3 are the same that you can experience tearing on some. I don't think there are any hard and fast rules about which will tear, though I could be wrong. But on my system, my 2 DVI->DVI screens tear, but my DP->MiniDP->DVI screen does not. So I put the non-tearing monitor in the center of my system so it annoys me the least. |

I believe it has to do with different digital signals and that current gpu's can only send one particular kind of signal true all the ports at one time. I have done screen tearing testing on both my 6950 and 7950, both cards respond in the same manner. Whichever screen signal is set to primary (via CCC or Win) doesn't tear including the monitors that are connected via the same kind of port. So on my 6950 I had DVI/DVI/native DP and I had to set one of the DVI monitors as my primary monitor to eliminate tearing on the other monitor that was connected via DVI. On my native DP monitor I had tearing. With my 7950 it is the other way around. It is connected via miniDP/miniDP/DVI and I only have tearing on the monitor that is connected via DVI. |
