3Dmark Vantage Resolution not supported

:hello:

I want to run 3Dmark Vantage, but when I click start it says something like "Minimum resolution not supported" The min res. being 1280 x 1024.

I'm using a 32" HDTV Toshiba Regza (720P) which can do 1920 x 1080, so why can't it run at 1280 x 1024?

1280 x 1024 isn't a supported resolution according to CCC, and for some reason I can't add it. (closest res. I can add is 1440 x 1024)

I can however set my desktop to 1280 x 1024 and also run games perfectly fine at 1280 x 1024, so its not like my monitor can't do that res.

Any help is much appreciated.
