| Post subject: | SLI works, but surround won't. |
So I recently bought another GTX 275 1792mb As well as my third 1920x1080 monitor. My monitor setup is currently 22", 24" 22" in that order, all running at 1920x1080 SLI is recognized and initially with the latest drivers 280 installed, surround **DID work. but it limited my monitors to a lower resolution than their native. And while it worked, it looked terrible and didnt have the quality that it contained when SLI wasn't truly enabled. So I read somewhere that using driversweeper and falling back to the 275 drivers would help my situation. I did that and messed with ALOT of restarts. Then after I did this, all three monitors were shown as a multi interface, but when I try to enable surround, then flash and the sound of "device disconnect" "Device reconnect" happens once or twice aaaaaand my side monitors are black and my center monitor will be grey. Only way to fix it is to manually restart. Should I clean out my drivers and start again or what?! Advice would be amazing. The two 22" side monitors are connected via DVI and my main 24" is connected via HDMI I'm thinking my drivers are all screwed up as well as maybe one of my monitors is being janky... Frustrating part is that they all have the same Resolution and refresh rate! |

From memory you need 3 monitors with identical sync polarity for surround to work. Which you dont have with two different sized monitors. Sorry, but it aint working for a reason. your solution is to get one more 22, 2 x more 24's (with identical sync polarity) or go to change to eyefinity. |

Hmmm well you say that, but I currently tweaked some things are am running surround at 5040x1050, while it is lower than my native resolutions. It's quite livable comparison and i'm okay with it. I also used this: http://widescreengamingforum.com/node/14976 To make my computer believe that there are 3 24" screens, however it didn't fool nvidia :-/ And so I believe because of the polarity difference im stuck at a lower resolution. But Surround works flawlessly otherwise. Just played some Cod:BO, Deus Ex and Portal 2 on it |

Hmmm well you say that Its amazing that you got a surround resolution to work, but he is right. "All displays must have a common resolution, refresh rate, and sync polarity" http://www.nvidia.co.uk/object/3d-vision-surround-requirements-uk.html |

Maybe if they still have matching resolutions refresh and such it can be made to work I guess. |

Although technically doesn't say that they need to be indentical monitors... I've got Surround working on non-identical monitors (two Dell 2405FPWs and one U2410) so I know it works, but I got lucky - they're all the same sync polarity. |

| Post subject: | the sync polarity is what |
the sync polarity is what counts, They dont have to be the same size or resolution, but they need to be able to share a common resolution, ie 2x 1920x1080 and 1 1024x768, so all 3 would run at 1024x768 so 3072x768. but obviously it may not look right if the monitors are different sizes |
