Well, I recently bought a 28" 4K Samsung monitor and it looks absolutely marvelous - it's sitting right next to my old 28" 1080p monitor and the difference is staggering! When I got the 58" 4K Panasonic, the pixels on it were pretty much the same size as on the 28" 1080p monitor, so the image quality difference wasn't that amazing compared to what I was used to but with this new monitor, which is close to retina resolution, the difference is amazing - I now understand why some people say that 4K is just a stepping stone to 8K. I don't think we'll ever need 8K content but heed my words, 8K screens are coming, because as we get used to retina displays on our phones and tablets, we become more sensitive to seeing the pixels on our TVs.
