Yeah, forgot to include the fact that I tried new cables as well as a
new power supply (runs off 12VDC so that was simple enough). Totally
lost on it.

Check pins 13 and 14 to see if they are grounded.

This problem is very strange. Maybe before you give up on it you can
flash the firmware on the monitor.

If you switch monitors on a PC that has already POSTed and booted,
does the machine crash? If so, I'd suspect that something is wrong
with the DDC pins.

See http://pinouts.ru/Video/VGAVesaDdc_pinout.shtml

Maybe pin 9 (VGA +5V output) is shorted within the monitor ???

You probably know this, but just in case:

Are you sure it's not posting? I had a similar problem with the DVI
input on my Samsung monitor. The system was posting normally, the
monitor just wouldn't show anything on the screen (not even BIOS). I'd
try a couple reboots, and eventually the monitor would light up.

Never did sort out exactly why. Samsung at one point suggested turning
off legacy USB - that did keep the frequency of "black boots" down but
didn't eliminate them entirely. Not sure why, since the monitor doesn't
have USB ports or a hub... I rebuilt the PC with a new mobo and the
problem doesn't exist on the new machine.
