A 32-inch 4K mini LED screen from Asus, while waiting for Apple's? | MacGeneration

Basically, a high resolution panel displays any screen surface: 1920x1080 (the workspace of a 22") or 2560x1440 (the workspace of a 27") or many others, everything is possible, as long as we are below the resolution of the panel (3840x2160. pixels)

We have more pixels than we display, so we do some smoothing

After ... if we want to do a minimum qualitative smoothing, the ideal is to take the pixels we had so far in our monitors ... and divide them by two in width and height

This cutting in two of an original pixel of our old screen, Apple calls it the "retina"

A classic 22" screen, displaying 1920x1080 pixels, if we cut the pixels in 2 in width and in height, we then need 2x more "mini pixels" in width, i.e. 2x1920 = 3840, and 2x more "mini pixels" in height, i.e. 1080x2 = 2160

3840x2160 = 4K

What is the resolution of the 24" iMac? 3480x2160

If we follow this logic precisely, then for a 27" screen you need more mini pixels. A front 27" screen is 2560x1440 pixels. So if we cut the pixels in 2 ... we need a 5120x2880 panel

5120x2880=5K

What is the resolution of the 27" iMac? 5120x2880

So

But we can also decide that we are doing things "wrong". After all, a pixel cut in 2 in width and in height (therefore cut in 4), it's a very small pixel, so good... why bother doing things right when you're a PC builder, and that 'we are more than an aberration (remember, 27 "screens in 1920x1080 ... for example) so we offer a 4K panel in a 27" monitor. It's very small, people won't be careful

And once we've done that...well, it's no limit, so we offer even bigger screens, but still with our 4K panel. 31", then 32", then 34", and even 40"

In the end, the basic idea is completely screwed up: to offer pixels so small that they can no longer be seen with the naked eye, this allowing a smoothing worthy of a paper rendering.

And it's true, it works ... when you buy Apple products (iPhone, iPad, iMac, ultrathin LG screen).

Otherwise it's not true, it's mini pixels more very mini, it's disgusting smoothing, it's gear for users not demanding on anything. It is enough to see the truly hideous design of the majority of laptop or desktop PCs to make a judgment
