| Post subject: | New to Eyefinity, some questions on tearing and what video card to get... |
Hey all First time poster long time reader :) I recently bought myself a Samsung MD230X3 and got a MSI R6970 Lightning to power it. After setting it up and playing games for a bit i noticed the horizontal scrolling line on my display port monitor, after researching i found this is a known issue. It this true? can i fix it? or should i go to nvidia surround to get rid of it? or is there a card i can get to stop this tearing? Thanks in advance for any reply's. |

Sadly, this isn't a resolved issue. Currently running 2x 6970s. Perhaps someone else has solved this, but I haven't heard of a resolution yet. |

Hey all What I have been told is that the tearing is a result of using non-identical video signals. That is, if you want to eliminate tearing you have to provide the exact same connection to all of the displays. Since AMD video cards can only support up to 2 monitors natively, in order to accomplish for 3 screens you would have to provide DP connections to all three screens. This likely would be accomplished using a DP Hub that provides connections to multiple monitors. In order to minimize the tearing during gaming I make sure the DP-connected monitor is one of the side screens and not the center one. |

What about the cards with 4 display port connections? would that fix the issue? ` |

What about the cards with 4 display port connections? would that fix the issue? The only information I have is that all of the monitors have to be using the same kind of connection. So, if you can get all of them connected via DisplayPort, I can only assume it would solve the problem. But, I'm not able to test it out due to lack of hardware of that configuration. |

Using the Asus DCII 6950/6970 (triple slot card with 4 x DP and 2 x DVI) will sort the issue if you hook up DP monitors to the DP ports only. Likewise hooking up 3 DP monitors to the DP ports on the 6990 will sort the issue too. I have 5 DP monitors hooked up to my 6990. I have no tearing on the 4 monitors hooked up to the DP ports. I do have that line on the DVI monitor. Not an issue for me tho as it's the one on the left so hardly noticed. |

I had to create an account just so I could help. I first bought a Sapphire 2gb 6950 Dirt 3 Edition and had this issue with tearing. It was extremely annoying. So to resolve this, and also since I wanted a bit better of performance, I bought the ASUS 2gb 6950 DCII Edition and ran all three of my monitors via DisplayPort (Dell U2311h monitors), using the Dirt 3 card as my second crossfire card. Works FANTASTIC. http://www.newegg.com/Product/Product.aspx?Item=N82E16814121431&Tpk=asus%206950 Also, both of them unlocked to 6970 shaders. :) |

I had to create an account just so I could help. As I stated above, all monitors need to be using the same type of connection in order to avoid tearing on any "odd" connected display. This is a known issue to AMD and they state there is no method to correct this due to how the signals are sent to the displays. |

Is this as simple as using VGA connection to all three monitors? Display port can be adapted to VGA, as can the other ports. Do you mean that all monitor's ports need to be the same native type? |
