Nvidia 7600GT Question: How to up the resolution when hooked up to my TV?

[RbSX]

I have no idea why but I can only up the resolution on my 46" Sony Bravia LCD TV, and my secondary output (DVI) can only be increased to 1024x768.

Any idea how I can change this?

1080p

Have you tried putting it in your primary DVI port? Also try a different cable. If neither work it might be a driver issue. Also check out if the Bravia supports up to 1080p over DVI, some TV's are quirky.
