I thought Ultra HD was 3840x2160 too, but I keep mixing it up with 4K and 8K resolutions.

I'm a bit confused on this one. I know there are different HD resolutions, but I can't recall which one is specifically called Ultra HD. I'll have to make an educated guess here.

Okay, let me see... Ultra HD is 4K, right? So the resolution has to be one of the 4K options. I'm going to go with C, 3840x2160.
