if you go to the Optoma site and look at the service manual pdf, the standard VGA connection is shown. all the specs are there including screen resolution and sync freqs.
Optoma used two different lcd's in the monitor: an IBM like zmoz has and a Toshiba.
if the display is blurry as zmoz says, the vga-to-lcd controller probably can be used with a different lcd. the vga-to-lcd controller is almost worth the $100. check out the prices at earthlcd.
Fusion Microsystems still has some unsold. i ordered one today.
i will try to put a i-opener mb inside the Optoma case or something similar and drive the tft with the i-o vga out. since the lcd is 12.1", it cannot go into the i-o case. that is what i think can be a cheep and easy way to go to tft on and i-opener.
the p233 computer should do as a cheep test mule for other projects.
Best Buy has a 14" tft lcd monitor, brand name 'MAG' at $200 after rebate (at least they did last saturday), but that would take the fun out of reutalizing hardware.
have fun, cheeply,
