Xbox Screen Resolution

I use a pc, but I have an ancient xbox without hdmi. I tried playing ffxi on the xbox, but the screen resolution is very low, compared to PC. For example, on the pc I use 1600x1200, the xbox was 720i or 720p, and graphics looked very rough compared to the pc.

I've heard that xbox that isn't ancient supports 1080i/p. Have you used both xbox at 1080 and pc at 1600x1200 or higher? Is xbox graphics still rough compared to pc?

Still rough, pretty blocky, and you don't get the config resolution option in the menu.
