im a graphic designer, my client a fast food lunch bar wants to do menu board lcd monitors and link all these together, for graphics I'm thinking I'll just do something in basic powerpoint slides, but whats needed to link all the monitors to one SD card or a computer to serve them all?
for 6 monitors you will need:
3 graphics cards, HD 4550 or 4350, 2 montior per card, cheaper but requires 3 pcie slots.
2 of the newer HD 5750, 3 monitors per card, more expensive and only requires 2 pcie slots.
The 5xxx cards require 1 of the displays to be a displayport lcd. I would suggest looking on Matrox's site for a workstation solution. They are know for multiple display cards. It wouldn't be cheap though.
DJRWlf, that's a USB connector, and it does not add 6 displays, it adds 1 per, which is limited to 6 without driver support under windows basic multi-monitor support, and likely you can do more with the increased # in Vista and Win7, but I'd need to double check to be sure.
However that's still alot of money per output.
REX, if all you're doing is showing the same thing on all 6+ screens, then buy a single cheap card or intergrated solution (heck an old intel Extreme would likely be fine), and then add the Splitter that Jebie recommended above. If you're not trying to display a bunch of things on many monitors, that's a pretty easy way to do it without worrying about multple cards, etc.
Heck even a single cheap dual output card and 2 of those gives you 2 distinct options multiplied by the splitter options for probably what it would cost you for any multi-card solution.
I'd say the VGA splitter (and preferably a built-in filter & amp to aid signal strength) would be the best way to do it for something as simply as just multi-screening the same menu.
