Eventually we must ask ourselves:  What is the difference between 4k and 1080p?

The short answer is this:

4k TVs have double the resolution of 1080p TVs

4k content has double the resolution of 1080p content

Another way of putting it:

With more pixels, we have more to look at.  Just like the difference between 720p and 1080p – higher resolution.

Critics of 4k say that 1080p is High-Def enough that our eyes can’t see the individual pixels.  But when you put a 4k TV next to a 1080p TV, the difference is clear.
