Do "roundie" color sets make a better picture than later sets?

To expand on the resolution vs. seating distance. For 1080P, the general rule of thumb is to sit 1.6 times the diagonal measurement of your screen, away from the screen. This is all up to interpretation by various recommended standards.

For a 70 inch HD set, this would be about 110 inches or 9.2 feet.

It has been said that the recommended minimum size of a UHD 4K set should be 75 inches or more to realize, in a practical living room environment, the benefits of UHD. UHD requires that one sit much closer to benifit from the resolution increase.

When comparing a 21 inch roundie, a flat panel, be it HD or UHD will give the viewer a much more emersive movie like viewing experience. This assumes the flat panel is properly set up in the viewing room. Your eyes will track the moving images on the larger screen, left and right, similar to a movie theater. Instead of being focused on a fixed point, you will be much more engaged with a larger screen and you may not fall asleep. :-)
