Don't pc monitors usually have higher standards? And some 4k tvs can be bad. For instance, a few tv manufacturers are making rgbw 4k tvs, which are tvs where 25% of the pixels are white and don't produce color. And also I think that a 4k monitor is more of a premium item. I think the assumption is that if you are buying a 4k monitor you can usually afford to spend money than someone buying a 4k tv.

An RGBW panel has R,G,B and W subpixels. The white is there to increase overall brightness. You can't count your subpixels and call it 4k (although oddly you can count three-thousand...something and call that 4k.). Or are you criticizing the decreased color fidelity that accompanies those higher brightness levels?

  Alright, I wasn't quite accurate on the specifics. But I'm criticizing the decreased color fidelity. I don't know how much a RGBW subpixel panel increases brightness, but I really don't think it's worth 25% of the panel losing the ability to display color.

    I still think you're making a false equivalency between pixels and sub-pixels. If you look at a microscopic view of an LCD, it is not a seamless field of sub-pixels--substantial surface area is non-emitting black borders between them, but the eye merges the sub-pixels (and pixels, if sufficiently high density) into a unified light source. Adding white emitters does not inherently mean you are getting "less color" -- many factors influence the blending that you perceive. It does, presumably, mean that colors at the highest brightness levels are less saturated, but that may mean you are getting additional, less-accurate color space, without sacrificing the accuracy of the color space you already had. I have no idea if RGBW displays on the market actually have these characteristics, but your dismissal is based on a misunderstanding of the optical properties at play.
