NVIDIA's drivers won't output interlaced for 1080i via the HDMI output. You'll 
need to use a converter or the HDTV component output supported cards. 1080p 
is 1920x1080 which should be possible by any of the 6xxx or 7xxx series 
chipsets. Some TV's will accept certain progressive outputs for 1080i though.
