willp Posted January 27, 2013 Posted January 27, 2013 A lot of multi-out video cards are display port/DVI/HDMI. Our (pretty basic) projectors are VGA devices and these cards often don't have the analogue stuff in them to support VGA. We're looking at putting together a video server (running Screen Monkey or similar). Suitable for running 4 projectors and a control screen (so 5 outs). Has anyone done something along these lines, any advice? Thanks, Will
pritch Posted January 27, 2013 Posted January 27, 2013 Displayport does seem to be the prevalent connector on multi-output display cards these days. That said, I've had considerable success with relatively cheap (£20-ish) DisplayPort-VGA adaptors, so assuming that your PC already has one VGA output, one quad Displayport card with four adaptors should sort you out nicely.
smalljoshua Posted January 27, 2013 Posted January 27, 2013 I use ATI Eyefinity cards in my servers. 6 outputs on Mini Display port. The 5xxx series ones can be found on eBay from time to time for a bargain price. Josh
lite_lad Posted January 27, 2013 Posted January 27, 2013 Personally id say you were best off looking at a Datapath X4 as this will mean you only need to use a single graphics card (possibly using a dual or triplehead2GO on the other output) and then converting to VGA as these run on DVI. These basically make the computer think it has a big display on it (say you wanted 4 1024x768 outputs it would be 2048x1536) and then you can set it to crop each output to look at a quarter of the image. http://www.datapath.co.uk/products/multi-display-products/datapath-x4
AHYoung Posted January 28, 2013 Posted January 28, 2013 Remember that allthough the inputs to the X4 or Digital only, the outputs are DVI-I so it outputs VGA natively without needing conversion on the DVI -I connectors. its also worth being aware that for higher resolutions and refresh rates you will require a Dual Link DVI graphics card. However my laptop will run 2560 / 1440 into an x4 @ 25p over hdmi no problem. id have suggested the X4 as we use them all the time, but didnt as it doesnt meet the "cheapest" part of the brief.
