I recently got a nice analog moniter at an auction, it has 5 inputs red green blue h sync / comp v sync now hooked these lines to a friends VGA card; red to red, green to green, blue to blue, h to h, and v to v. After turning the computer on, text could be read but the screen scrolled vertically as if the vertical sync was not working, in fact there was no change if the vertical sync wire was removed completely. What is wrong, can it be fixed, can I use this moniter with VGA? The moniter is 19" and says 'VMI' on the front, and 'Mitsubishi Color Display Monitor C-6921P' on the inside.

The specs I have on the Mits C6921 say that it's for 28-35 kHz horizontal and 40-70 Hz vertical, so it *should* work at the VGA timing (although it may need some centering, etc. tweaks). If the horizontal is locked in, then I'd look for a control on the inside labelled "V FREQ" or something similar. Also, check for a switch or jumper which might be used to configure the monitor for "sync-on-green," which you're undoubtedly not supplying. The "VMI" probably stands for "Vermont Microsystems," a small company which manufactures PC-compatible graphics cards (not just VGA timing, though). Bob Myers KC0EW HP Graphics Tech.
