Cannot get CPU to recognize Tatung LCD Mon...

My desktop computer crashed and I had to reinstall all software. Since then the Tatung Monitor L17AMTN will only display in extremely low resolution (480x600) stating the montior is not being recognized. Sounds like it needs a driver right?

I went out to Tatung's website, downloaded the *.icm and *icf files, and saved where they stated. But this did not work. I believe the files are for Windows 95/98 and I have XP.

I emailed Tatung asking for the XP driver and they stated this monitor is a Plug and Play, not requiring a driver. I've tried disconnecting and reconnecting the monitor, but it doesn't pick up that there's new hardware.

Help! I'm so frustrated because it used to work fine.
