Why your next TV must be a 4K

[NewVista]

By way of illustration, remember those awful SD plasmas that would kind of match pixel for pixel 480p? Clearly not the best way to display legacy TV programs. Upscaling to overpixeled 720 format was way better. Now extend that analogy to 1080p. What do we need? 2160p: smoother, less visually fatiguing, especially @ >70", which is what you should be looking at.
