Re: [seul-edu] Need advice with LCD projector



I hooked up a monitor and set up xwindows for 640x480 generic VGA. The
projector and monitor both display fine in text mode. When I switch to x the
projector goes blank but the monitor works fine. What was the model of your
Sharp projector? And I wonder if it makes a difference if you run it off a
laptop vs. a desktop?
