We rarely see from Movies or TV shows a person in a striped shirt with very tight spacing on the stripes. When I have seen such things shot in HD it has a weird wavy effect. I wonder if going to 4k would solve such a problem. Also, I am sure there are other such issues, that many of us laymen are not aware of either.

Of course, I am not saying we need to replace our 2k sets with 4k just to handle these small issues. But, it is likely when we go to buy a projector or tv in about 2 or 3 years, 4k is going to be the only choice. I am excited at the possibility of getting better performance for not really much of an increased price since I do plan to hopefully buy a projector in 2-4 years.
