HDTV problems.

Okay, so my TV has the Component ports for my HD AV cables that connect to the Xbox 360 for High Definition use. When I plug them in, set my cord to HDTV, and then turn on my 360 on the Video2-Component channel, it comes up with dual-screens that're squashed together, along with the color being somewhat **** However, if I switch my cord back to TV, it works fine, but doesn't seem quite like HD.

Now, I don't even really know if my TV is High Definition or not, but it does support the Component cables. My question is, am I just doing something wrong, or is it just that my TV just can't reach actual High Definition?

Any and all responses will be greatly appreciated, thanks.

Okay, that actually helped. I google'd the model number and found some info on it. The description says that it has Component cables, but it's still only a standard definition television. Poo. :[

Oh well. Thanks for you help, man! I really appreciate it.
