hi, ive got a dell inspiron xps and i would like to know if its possible to use the monitor on the dell as my primary monitor for my desktop computer? im going to college and instead of carting a crt monitor over there i would like to bring my dell since i cant come up with an lcd monitor right now. is there a program that i could use or a way to let me run a line from the s-video output on the other video card into the dell or is it impossible? any info is sweet, thanks.
