Hi, I need some guidance in (hopefully) fixing this minor problem. When setting up my PlayStation 3's display settings, I notice my TV (which does support up to 1080i) kind of has that refreshing/flickering effect you see on old CRT monitors... but this only happens when in 1080i mode. When I switch back to 720p everything is sharp again. I know for a fact that my TV can display 1080i fine because that's how I have my Xbox 360 setup and everything works perfectly fine... although I do notice a light purple wave travel across the screen, but it's only noticeable in dark scenes (what is that, by the way?). I have my 360 going through Component and my PS3 through HDMI -> DVI (my TV doesn't have HDMI support). I have Sony's official Component HD cables on the way so I'm hoping this eliminates the problem. So I guess to make a long post somewhat short... how can I get my PS3 to output in 1080i clearly like my 360 currently does? Also I guess while I am here... is there really that much of a difference between 720p and 1080i? I Googled it, but I can't seem to find a straight answer. I play Call of Duty 3 in 720p and everything looks excellent, so can it really look that much better? If this post is unclear, please tell me and I'll try to clear it up. Thanks!
