3 Monitors with 1920x1080 Native Resolution won't do 5760x1080
Hey Everyone, After struggling on my own to get a resolution of 5760x1080 in Surround with my 3 displays, I've had no luck and I'm hoping these forums will be of some help. I have 2 LG Flatron W2442PAs, as well as a Samsung SyncMaster S24B30BL. I wish I had 3 of the LGs, but by the time I built my new rig and wanted to set up surround, they had been discontinued. :( The LGs are full 24" displays, and the Samsung is 23.6", however all 3 support a native resolution of 1920x1080. I'm using 2 680s in SLI, with all displays connected via DVI, 2 in one card, and one in the other (I've tried switching which ports they are plugged into in every combination possible). When all displays are set to active, they run at 1920x1080, but as soon as I turn on Surround, the max res I can get is 5040x1050. It's so dissatisfying not to have it running at 5760x1080 like I had hoped Surround would on these displays. I've tried with the Generic PnP drivers and with the LG/Samsung drivers applied to the appropriate displays and it still maxes at 5040x1050. I've also tried applying the same digitally signed .inf file intended for the LGs for the correct profile type (digital) to all 3 displays, as well as .infs I created myself that aren't digitally signed in an attempt to override the EDID info and had no luck with either methods. After a clean install of the Nvidia drivers and trying the last 2 methods, when I go to apply Surround, the Nvidia drivers think for a second and then leave SLI turned off and Surround never enables. Any ideas? This is driving me nuts. Please help! Cheers, Jake

As far as I know, Nvidia requires that each display has exact matching EDIDs. So provided that the 2 LGs match up, you need to override the Samsung with an Inf from your LG. http://support.acer.com/acerpanam/monitor/0000/Acer/AC501/AC501faq10.shtml http://www.geforce.com/hardware/technology/3dvision-surround/faq You might try SoftTH, I've never used it. But there's lots of reviews on youtube, it might not be EDID dependent like Nvidia surround. With AMD eyefinity, it doesn't matter if the EDID or resolution match. Unfortunately, Nvidia is picky.
