No, LG do too, and of course until Apple introduced their own it was the LG UltraFine Display that Apple themselves sold to fill the gap.

Let’s not even talk about that steamer. Horribly unreliable and poorly made bit of kit with serious quality control issues.
The main point is that the PC market is constrained mostly to 4k because, well it’s cheap and the PC market is people buying to a price not a specification.

not everybody buying a PC which by the way is what macs also are are buying to a price. I always look at specification first, then find a decent compromise but I will pay more for better kit that will last before an upgrade rather than sell myself short.

4k native -> everything too small
4k 2x scaling -> everything too big
4x 1.5x scaling -> everything right size but too blurry
5k 2x scaling -> just right
I wouldn't say it's 3x what your eyes can pick out. It's very very obvious the difference if you sit in front of a 5k display versus a 4k display for all of the above cases.
Chuck in decent dynamic range, colour calibration and there's a winning combination. Apple are the only supplier shipping 5k 27" which is super super popular with anyone doing graphical work (and programming now) because it's the sweet spot.

Okay, I think I know what you are going on about.
As far as I know, Mac and Windows uses different compromises for non-integer scaling. I only use Windows and text is sharp down to the individual pixel on my 4k display using 1.25x scaling. The problem is that some older programs render incorrectly. They either do not scale at all leaving the text too small to see or they use an ugly uneven-looking non-integer scaling of bitmap images.
From what I've read on the Mac, people are reporting very different results with 4k displays. Some people have sharp text while others have unacceptably blurry text. It might even depend on the particular display and how Apple interprets the EDID.
As far as I know, the ideal behaviour on a Mac for 1.5x scaling to 27 inch 4k is to render at 3x 2560x1440 and then scale 0.5x with anti-aliasing to 4k. There should be no rendering defects, but it seems to me that the text would be blurrier than on Windows.
Simon:
You could always try netbeans on a 4k display if you want to know what blurry text actually looks like, I'm buggered if I can figure out how they could get it that wrong.

That's probably windows vs JVM more than anything. The whole of windows high DPI is crazy fucked up. I've got a Dell here which is a 3840x2400 on a 15" screen and everything renders fine apart from SQL server management studio. The task bar icon for it is 1:1 pixel ratio so about 3mm across :palm: :palm: :palm: :palm:. If you open it, it opens at 1:1 pixel ratio as well. No attempt at DPI scaling.
