Hi:
I've gotten a hold of a 7 inch screen that I would like to add to my setup. My questions are: can I output to 4 monitors with 2 7800 cards (not running sli)?; is there any way to convert a vga or dvi output to the 1 video componant cable (which fits this particular screen)?: this screen only runs off of a car battery. it takes 12 volts and 600 amps according to the Radio Shack guy. I tried splicing on the approriate wall outlet power source. It ran fine, but after a few minutes the power source started to melt

. any way to power this thing from a wall?
Many thanks
