TV Trouble!

I have a Samsung LE32C530 televison and I am having some trouble getting the best settings for my XBOX 360 and was just wondering if anyone could give me their advice, I understant the odds of someone looking at this post and having this TV are very slim but worth a try eh. Cheers people.

The highest resolution for that TV is 1080p. Does your Xbox 360 have an HDMI port on the back? If so, are you using it? If not, you should be to enable the highest settings available and the best picture quality.
