If you bring that LCD back to life, there's undoubtedly an A/B source switch to choose between the VGA HD-15 feed and the BNC Feed, so you can have one LCD do double duty from the same CPU via the two connectors.

Persnally, I have a 22" CRT to the left, the 20" Dell UltraScan doing 1600x1200 in front of me and another 19" version of same running 1024x1280 in Portrait Mode . . .

. . . actually, haven't had time to hook everything up as yet, I just moved into the bedroom my last roommate trashed. Gotta find another so I'll have money for toys again.

I'm not sure I even have a PCI Card that'll output 2048x1536 to max out the CRT. :-/
