any VT525 terminal users? with LCD?

I saved a couple DEC VT525 terminals a year ago or so from a barn and after cleaning them up, they seem to work mostly with the exception that the video they produce on a number of different VGA LCD panels is quite dim. Both terminals exhibit the same issue each on a number of different LCD panels-- so I'm a little hesitant to blame something wrong with the terminals and rather wonder about the VGA-ness of the signal they produce. I gather from the specs that it should be producing a 800x480 @ 73 Hz signal. My monitors claim to do that and don't complain in any way... other than that the video is pretty dim and washed out. Is there an existance proof of one of these working with a modern (3 or 4 yr old) VGA LCD panel or were they only successful with pre-LCD CRT monitors for some reason? Chris -- Chris Elmquist
