Hardware for running three HD Displays

Hello,

I need to run three LCD/LED menu boards for a restaurant in HD 1080p. What hardware will I need to get the job done. I am assuming a moderately fast computer with three GPUs capable of HDMI output. Any suggestions will be appreciated.

    Hi, essentially anymodern video card from nvidia or AMD will drive three displays. The trick will be finding a card with three HDMI/DVI outputs (rather than two HDMI/DVI and one display port).

    Here is one possibility. 4 DVI output (2 discreet displays split to 4). http://www.newegg.com/Product/Product.aspx?Item=N82E16814162083

    Use DVI to HDMI cables. (DVI is the same as HDMI except DVI does nto carry sound. The cables just put the connectors on each end. I use a DVI to HDMI cable to connect a PC to a 50" plasma. Works well.) http://www.newegg.com/Product/Product.aspx?Item=N82E16812270113

    I'd drive the video card from whatever small server is lurking in your basement that has a PCIe x16 full size slot. The card above take essentially no power, so pwoer supply size is not an issue. If you need to buy a new PC a minimal one like this one shoudl work (make sure it can take a full size PCIe card): http://www.newegg.com/Product/Product.aspx?Item=N82E16883108704

    If you have a motherboard capable of three way SLI, grab 3 GTS 450's off of Ebay for 80$ each.

    If you can only do 2 way SLI, grab 2 GTX 550TI's and run 2 monitors off of a splitter from the second one.

    He's running a sign. One low power 4-DVI card is $89.99. Two of any two DVI output would work also, but the MB cost goes up to get SLI or crossfire. Not sure why'd you'd spend $250 to $300 for three GTS450s to run a sign plus the money for a MB with three PCIe long slots, but you could.

  5. For AMD, you need an active dual link DVI to DisplayPort adapter to run one of the three screens.
