I played NBA 2K3 on my XBOX last night. It is one of the two XBOX games that has a 720p signal. I tried it both with 720p "yes" and 720p "no" selected on the XBOX inquiries of what my TV accepts natively. When 720p was selected, the image was MUCH better. It is the best looking game on my XBOX. The jaggies around the players and letters almost completely disappeared. The animations were silky smooth. The TV also locked into full mode (this has never happened to my set before). The signal had some quirks though. The starting lineups took up about 1/3 the space on the screen they normally do and the ESPN ticker in the lower right hand corner was also about 1/3 its 480p size. Also, at the team select screen, the team logos took about five seconds before they would appear (no delay in 480p). Overall, I'd say the picture with 720p selected is about 20% better than when 720p is not selected. Oh, I tried holding the buttons down at start-up but never got a prompt asking me about resolution. I also started-up without holding the buttons and noticed the same picture quality. The problem is, my Sony KP51HW40 TV is supposed to downconvert 720p to 480p, so I don't really get what's going on. I would have thought the signal would get worse as a result of the downconversion when compared to a natively displayed 480p. I don't have an HD tuner, so it is tough for me to tell if I'm viewing a 1080i, 720p, or 480p signal due to my lack of experience. Does anyone know what's going on or what might be causing this might be causing this? Any help would be greatly appreciated. Also, thanks to Dave F for pointing out a similar situation on another thread (he used a similar Sony HW model and Tony hawk 4) and prompting me to try it.
