I do know mate but that's not how he meant it...
I have 1080p, 1440p and 4k monitors and not only understand their differences but can physically view their differences with my own eyes...
By his recogning... All this time running 2x 1080p side by side with another 2 more on top and then spanning the picture across them all gave you a better picture quality than a single native 2160p monitor???
That's how his comment reads to me and that's crazy!
What he is saying is, it is down to the PPI. In the example he gave he said 4 x 1080p screens stitched together making up a 40" screen is the same PPI as 1 x 2160p 40" screen. The point being, if you are looking for an improvement of image quality, you need to increase your PPI.
That is what I understand from what he said
