Sorry I meant the various 4k videos all over the net, Not the game obviously. Most notably this one: https://www.youtube.com/watch?v=SAUkzgPNjbE, switch up to 2160p on a big monitor and take a look at the difference.
This goes for all movies too. Bluray 4k rips look way better than HD 1080 rips on equivalent monitors.
Doesn't that warrant 4k monitors already being worth it to buy if we can definitely see the difference on many different multimedia? Or am I missing something big here?
