let the down votes rain in on me for what i am about to say.
this is stupid.
that resolution, at that size, anyone who works in 3d programs or video editing would need to re size the ui, making the jump in dpi next to pointless.
"but everyhting is sharper and looks nicer"
im on a 24 inch 1920x1200 monitor, my head is less than 3 feet away, and with black and white text, even zoomed in what is it... 175% for this specific site to make reading at a distance easier, i don't notice jaggies in the text, THE MOST PREVALENT PLACE FOR IT. please go on, tell me why a 4 k monitor at 32 inches is better... tell me, i want to know. because as far as i know, 90-120dpi is a sweet spot for pc monitors, the standard ui is large enough, and allows most programs to run perfectly without scaling the ui.
you want a 4k monitor, than it needs to be about 48 inches to give you the same dpi that my current 24 inch has, and i know this for a fact, just making the dpi larger IS NOT what a professional environment needs or wants, what they want is more screen real estate, thats why its common to see 2 or 3 monitors at a workstation, with a scaled ui they would STILL NEED more than one monitor.
sure, ill give one area where this would be good for.
looking at the final product
lets say you just have this monitor for the preview in photoshop, or to see a full resolution video you are working on, but this will not be the monitor you do most if not all your work on because it would be stupid to use it for that.
