I've spent the last few days trying to get the best picture out of my Xbox 360 with my TV. I've read loads of stuff and fiddled with various settings etc and now my head is ready to explode with confusion.
My TV is a Sony Bravia KDL-40W4500, which is a 1080p set. I'm connecting to it via HDMI and no matter what settings i have the reference levels/HDMI color space on i either get crushed blacks or a totally washed out look. I did find a solution where i could switch the reference levels to standard and put it on RGB and that was ok but somehow i thought the picture didn't look as rich. The TV has no black level setting i could find just something called colour space which was either standard or wide. The only difference it made as far as i could tell when i switched it to wide was to saturate the colours more.
Then i decided to disable display discovery and suddenly i had the option of selecting various PC resolutions. The highest one i could set it to was 1360x768. I switched the reference levels to expanded and left it on RGB and now i don't have the problems with crushed blacks or looking washed out. I'm wondering though, given that the TV is 1080p am i losing any significant picture quality by running my Xbox 360 at 1360x768 resolution instead of at 1080p? Would the other 2 resolutions available be any better/worse? They are 1024x768 and 1280x1024.
