SIS 315 TVOUT won't work past 800x600

I want a board with decent 3D performance and a TV OUT that will work when my desktop is set to 1280 x 1024 resolution. The board I bought uses
the SIS 315 and 305 chips and is made by H.I.S. I bought it because it has dual monitor support, TV out (the box said RCA and SVideo, but it lied, it was
only SVideo, so I bought a $3 adaptor) and the box specifically said that each monitor or the TV and monitor could be set to independent resolutions
and refresh rates.

Well, it AIN'T TRUE!

When I enable the TV output, it changes the resolution on Display 1 to 800x600. Yuck.
I've found that NVidia cards with TV out are even worse, even the ones with dual monitor support like this one. They force you to go to 640x480 or
live with TV output that only outputs part of the screen.

Is this a driver problem with Win 2K drivers?

I'm upset because the box promised me better.

IIRC, WinNT/Win2K don't play nice with TV-out, and here's why:

When those OS's have more than 1 display (of any type), they try to extend the desktop in such a way that they don't allow you to have different refresh rates/resolutions. Apparently you don't have that issue in Win9x/Me. I don't know about XP.

I'm sure about Win2K--- I have the Radeon 8500, and when I want to watch a DVD piped out to my tv, I have to adjust the video settings. Not difficult, but it kinda sux.

EDIT: Also, if you have a normal TV, you're limited to 800x600 or lower (1024x768 if you're lucky), at 60Hz refresh, when using the tv. Man that bites on the 19" pc monitor.

I use XP and a GF2 MX400 with TV-Out, and 800 x 600 is the max resolution. Most TV-Outs are like that. 😉
