3 displays (2 touch 1 non-touch)

Ok, I got 2 15" touch screens (different brands) and one samsung 22" display. now when I run two at a time im good, but I want to set it up some how so i can run all three at a time

I have dual ATI 5770HD (two of them) card running in crosfire mode (i think, they have the connector connecting them together) with three displays

touch screens are VGA screens (two)
samsung is DVI/VGA capable (would prefer to use DVI)

I currently have them hooked up the following way

Touch screen #1 DVI -> VGA cable
Samsung HDMI -> DVI cable
Touch screen #2 HDMI -> VGA adapter -> VGA cable


what I really want to do is get it so i can use all 3 and have my flight simulator main window on the samsung with the other windows that are used to control the plane (panles with switches, ect) residing on the two touch displays, but at this time when I try to use the touch screens (either one) they mess with my main display (mouse remains on the samsung and its really difficult to control any thing). so anyone who has experience with something like this I really could use the help!!

I may be waisting time as im planning on reformatting my machine once i get my hands on a SSD (revo X2 drive I think) but that wont be for a while so im not concerned anyways, just want to get this working so I can do what I want to do till that time!!



Thanks for the help!

well my machine will only have two switched on at a time

either 2 touch or one touch and the samsung, i haven't been able to get all three to work together. as for the game im not entirely concerned about that im more wanting to get all 3 displays going so i can have all three running side by side (i know its possible but can't seem to figure this one out and i do attempt to install the drivers that came with my cards and it seems i get the lovely BSOD, so i may just wind up reinstalling the OS to resolve this whole mess, but im just hoping there is a work around possible in short of a reinstall that i can use until I am able to get my hands on the SSD I want to grab


and this is Flight simulator X if that helps.

ok I can just skip that as I have just tried that lol, and still no go (thats where I get the lovely BSOD when installing the drivers).

i could be way way off but isn't the 3 monitor setup part of the eyefinity mode on those cards, so assuming you've not setup eyefinity correctly you won't get all 3 screens working.

also my experiences with 3+ monitors is somewhat limited but if they aren't attached to the right ports then you won't get all 3 either, they usually require the 3rd display to be on display port and not any other port available.

if it doesn't help sorry i was just rumaging round my brain for idea's :)

edit: you can run all 3 monitors from a single card using eyefinity as well which is maybe where your getting something wrong and using a port on your second card.

sadly i tried all three on one card, with all 3 on one card with both cards hooked up, and putting two on one card and one on the other and any other possible combination possible

what ports are you putting them onto if you use one card?

from what i understand of single card eyefinity setups the 2 dvi ports should work and a display port/with adapter, the other ports won't work for a third display.

it points out though that a third display must come from the display port as the card can only drive 2 monitors from dvi/hdmi combo's.

i can only assume crossfire is the same untill i do some more checking

and to answer my own query on crossfire 3 monitor setups.

all monitors must be connected to the same card 2 to dvi/hdmi 1 must go to display port.
