[quotemsg=14688102,0,133701]Anything past 1440p or 1600p on a 27" display is pure retardation. People gobbling up the 27" 4k displays are pretty much the lowest common denominator. 4k on big 50" displays makes sense, especially if you're sitting very close to them, but to justify anything past 1440p on a 27" display you need to have the monitor 6 inches from your eyes.
1080p on 27" display isn't that bad, especially if it's going to be a first gen glasses-less 3d display. Maybe a 2nd gen model could bump up to a 1440p.[/quotemsg]
You actually have this backwards - see this article - it proves that 4K and higher res monitors make sense while a 50" TV is silly.
From the conclusion:
"On computer displays there is definitely something to say for 4K. You can display a lot of information simultaneously and you usually only have to focus on a small area at the time, which means the higher detail really has added value. Furthermore the short viewing distance allows a wide field of view without the need for extremely large displays. 8K might have its uses with very specific applications, but in general it would be excessive.
With televisions it’s a different story. Many people probably aren’t even making full use of their FHD TV yet. To really profit from 4K you’d need an extremely large screen, or sit extremely close. And 8K is just plain ridiculous. For a 250 cm viewing distance you’d need a 595 x 335 cm screen. There aren’t that many people with a wall that big in their house and even if you had, you’d need a pretty impressive beamer and a very large projection screen (they obviously don’t make TV’s that big).
One of the reasons that 4K televisions sell relatively well might be that in the store people tend to look at it from a very short distance, at which they could easily see that 4K is sharper than FHD. If they would look at it from the same distance as the actual distance they would view it from at home, many would not be able to tell the difference (if all other aspects of the image reproduction were identical for both displays). Manufacturers know this, so from a marketing perspective 4K is very clever."
