Resolution questions about Xenarc/Powerstripe

Just got my Xenarc a few hours ago! Boy is it beautiful! I have milkdrop fullscreened on it as I type - gorgeous....

Anyway, I've tried configuring powerstripe to give me 800x480, but am having little luck. It's at that res right now, but the Display control panel says 800x600 - the screen simply cut off the bottom 120 rows of pixels.

I have it running on the secondary port of my X800 right now, but will be moving it to a Millenium II on my car box soon. Anyone have any thoughts about this?

Oh - thanks for the speedy service ZipLock!

well, you dont say what type of video card you are using... and your link in your signature is broken, so we can't help with your exact video card... but here's my guess...

you are probably using a non-supported video card for PowerStripe... try a different video card...

Oh boy... Sorry to waste everyone's time. It looks like I forgot to :search: before adding this thread.
But if anyone's interested, it's a Radeon X800 (Powercolor) vid card. I have been able to get Xenarc's timings entered into Powerstrip, but the OSD reads 640x480. Pressing the <-> button jumps the display up to 852x480/60. I've tweaked every setting and no luck...
