4K TVs Continue To Rise Despite TV Shipments Dropping

For HDR purposes LCD's have a lot of trouble hitting the contrast level they need to because of their inability to produce anything truly close to black. Due to this, they need to push rather insane brightness based on what we are used to. The white subpixel allows them, in essence, to double(or more) their brightness and achieve the level of nits they need to offset their very poor blacks.

They actually have created two different HDR standards, one for OLEDs(for point of reference, plasma TVs would use this if they were still around) and one for LCDs. The contrast actually still favors OLEDs(which have infinite contrast available to them by nature) but it at least allows LCDs to get to non embarrassing contrast levels, albeit at the expense of a torch level brightness the likes of which most people have never seen before Smile

This white subpixel that supposedly doubles the brightness does so at a cost, putting colors and gamma all out of whack.  I'd avoid this brightness boost like the plague, if I don't want mucked-up colors.

We’re confused by the purpose of an RGBW LED LCD TV. Yes, it can resolve 3840 pixels horizontally and 2160 pixels vertically (though not both at the same time), but that’s beside the point. The diluting effect of the additional white subpixel damages colour fidelity irreparably: by trying to shoehorn RGB video signals into an RGBW matrix, colour information is lost, and users will never be able to enjoy movies in the manner intended by the director.


Fuck the white light boost that fucks it up all for marketing purposes!
