This image is very misleading because the layers are arranged in the opposite order from the viewers perspective . The quantum dots on this product are used for the enhancement film ( QDEF ) , they are placed right after the backlight layer in order to enhance the blue light of the backlight as seen here :
It's a shame to see monitors being this far behind in terms of technology because this is essentialy old quantum dot technology used on commercial TVs from 2013 . Nowadays (from 2019 and on ) TVs have the quantum dot layer also applied infront of the LC layer much closer to the eye of the viewer , this is called QD color filter ( QDCF ) as seen here :
( In this example QD are not used to enhance the backlight )
Yet in PC monitor market we get to enjoy 2013 technology in 2021 .... Can't wait for OLED to shake up this lethargic PC monitor market !
Are they able to make QD color filters at the types of pixel densities monitors require, at sufficient brightness? That's the main question here. I would guess there are technical reasons for this not happening - if not, they could just make the same panels on the same production processes in the same factories, just denser and cut into smaller final sizes.
Also, as mentioned above, OLED has severe issues for large parts of PC usage, with burn-in/image retention still not being solved. It's partially manageable, but it's highly usage dependent (OLED is essentially fine for movie and varied gaming use, but if you play one game
a lot or use the desktop a lot, you're going to get retention of various parts of the UI after a while, and no mechanisms for lessening it can fully fix the issue. QD-OLED might alleviate this further by using a single color optimally tuned for longevity for the actual OLED layer, but you still can't get past the fact that organic LEDs degrade over time, while non-organic LEDs essentially do not (yes, they also dim, but at a
vastly lower rate). If all you do is game (many different games) and/or watch movies/videos, OLEDs today are great (if large). If you spend a lot of time on the desktop or in the same game, LCDs are still going to be better for years to come.
Edit: The HWUB review is in. In summary: As expected, this is very close to the Asus PG32UQ - though not identical. The panel is likely the same though, as response time performance is
very similar - just tuned slightly differently (trading slightly more overshoot for slightly faster response times). No single overdrive mode is really suited for the full range of refresh rates though. The stand-out is color gamut and accuracy when calibrated, which is
staggeringly good. So, if what you're after is a do-it-all monitor with a strong emphasis on content creation/photo+video editing but also
good (but not
great) gaming performance, this looks like the best 32" 2160p144 monitor out there. But it still doesn't come close to the panel performance (response times, overshoot) of the ~27" class panels still. Seems we have to wait for the next generation of 32" panels for that to happen (at which time the 27" class has no doubt moved on once again).
