Honestly theres no difference between the "offical" and anyother HDMI you buy. The "offical" one is there only so M$ can make some more cash. Most likely, you won't be able to notic the difference between 1080i & 1080p

The official Xbox 360 HDMI cable is just manufactured by Microsoft instead of some 3rd party company.

Yes, there is a difference between 1080p and 1080i. The pixels on your television will be smaller with a 1080p resolution. Therefore, you get a better picture. That is why the newer LCD and LED televisions that are 1080p are more expensive and at higher demand because the picture resolution is better. HDMI Cables support up to 1080p. So, if your tv also supports 1080p you're going to get the best picture resolution by setting it at 1080p.

I hope this answers your question.

There is no difference just one is making money for bill

and 1080i and 1080p are about the same you wont be able to see the dif if you arnt recording your tv with a recoder
