3 Monitors, 1 graphics card
My work PC has (as you can guess from the title) a single Geforce 9600GT card. According to the spec page for this card, both DVI ports are Dual-Link DVI. Both are currently in use on Dell 19" 1280x1024 screens. I'm running Windows 7, with Aero enabled, for what that's worth.
What I'm wondering is if I can use a standard DVI splitter cable to drive a third screen from one of the ports -- specifically a Samsung 22" 1680x1050. I'm really outgrowing the two-screen setup, and am strongly considering bringing in my home monitor (which is almost never used) to bolster my usable space. If I can't, then my alternative is to replace one of these Dells with that Samsung, to give me at least a "little" more space.
(Before you ask, there's probably no chance I can get my company to spring for a second video card and third monitor. Even if I could, it would not be politically expedient, as a number of my other coworkers are already pretty jealous at my setup.)
This is the closest. I ended up dropping my old nVidia 8400GS in the machine and using it to drive one of the 19" Dells. (I forgot that I had that sitting around!) So far it works like a champ, but I'd like to replace the VGA cable from that old card with a DVI. (Both the card & the monitor support DVI; I just didn't have the extra cable.) – John Rudy – 2010-04-23T18:12:09.957
