What I don't understand is the marketing. Back when high definition was coming out, it was marketed as HD. Then when those 720P and 1080i tvs were in homes, they decided to lie to people by telling them they didn't have "full" hd, which was 1080P. After everyone went out and got themselves "full" hdtvs, then they decided to sell 2160P sets as "ultra"... even though they already told them 1080P was "full".
Here is the definition of full.
1.
containing or holding as much or as many as possible; having no empty space.
2.
not lacking or omitting anything; complete.
If full means holding as much as possible, then 1080P is the highest resolution mankind will ever produce and therefore, 2160P is pointless.
