Is this the process to switch the 360 from a standard TV to a HDTV

First off this is the TV I am using.

First thing I did was switch the switch on the cable that goes in the back of the 360 to the HDTV option. Next I plug the component cables into the back of the TV and then powered both the TV and the 360 on. And then I went into the dashboard on the 360 and changed the settings from 480p to 1080i. I did all this and the picture seems a little better but not much better then when I had it hooked up to my Sony with just the standard A/V cable(yellow,red, and white). I am just worried because I read on the XBOX.com forums that there are alot of bad Component HD AV Cables out there(the HDTV to TV switch seems not to work). Is there a way I can tell if my cable is ok before I call Microsoft?

Any input would be a great help since I am new to this HDTV stuff and cant seem to get a handle on it yet.

Thanks,

The picture shouldn't necessarily look better... but the image will be sharper and more vibrant.

Check out the difference between 480p and 720p to see what kind of a difference you should be seeing though not as dramatic since 1080i is not as good as 720p. It's very, very close though.

I'll assume you're using the provided HD cables with the 360 and they're good quality cables and I don't think there are any others on the market at the moment. And it sounds like you did everything right...
