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.
