acer pd100 projector

got this projector and i wanna play some giant GW lols, i'm using xp with dual 8500gts currently in sli mode, the acer is connected to the vga out on one of the cards but i get no signal although nvidia control panel sees the projector

sounds like its the projector
where did u get it?
was it workin before?
does it turn on at all?

if the projector itself is in good condition and u've used it with other sources
then...
r u using a resolution supported by the projector?
r u connecting it as the primary display? or a secondary display with ur current monitor still connected?

even if the device is recognized
make sure to properly set up the multiple displays

lastly make sure u use the acer drivers specifically for that projector
instead of generic ones

other than that...i cant really think of anything else

u can try runnin it as the -only- display device from boot-up and see if u get any signal
(simply unplug ur other monitor and reboot up the pc)

This would be my first question, except I would say resolution and refresh rate.
