I thought even console gamers would understand resolution by now thanks to high res phones and tablets, but no, they still claim there's no difference.
4k on a 28" is ~160ppi, still fairly low. Using it at computer monitor distance it will be noticeably better than 1080p.
I have a Nexus 10 (I think it's still the highest res tablet out there) at 2560x1600 (300ppi) and a nexus 5 at 1080p (~450ppi) and I can see a difference clearly.
160ppi on a monitor is not overkill.
Sorry that is not how it works. PPI is a worthless statistic without viewing distance also being taken into account. Truthfully it's PPD (Pixels Per Degree) that makes a screen amazing. And to qualify as an Apple "Retina" display" you need at leas 57 PPI with 20/20 vision, and much higher like 79 ppi with 20/10 vision.
160ppi viewed at 24 inches, times Pi, diivided by 180 viewing degree = PPD
160 x 24 x 3.13 % 180 = 67 PPD
So there you have it, 160PPI viewed at 24" gives you 67 PPD, which is about half way between the PPD of an iPhone 4S (57 PPD) and a 13" Macbook Pro Retina Display (79 PPD)
And the reason the iPhone has a higher PPI (326) yet a lower PPD (67) is because the iPhone is meant to be viewed from around a distance of 10-12 inches, not around 24" like a computer monitor or a laptop display..
