I have a Sony DVP-NS75H that has the capability to display 1080i resolution. It is input to my Hitachi PJ-TX300 projector via HDMI/DVI (HDMI cable with DVI attachment for input). The PJ-TX100 also has the capability to display 1080i. Whenever I play a DVD it will max out on 780p. When I play on my XBOX 360 it will display 1080i. Any changes to the video format that I have to do? Any other ideas?
