HDR Color And Luminance
New to our monitor workflow, we've utilized some of CalMAN's recent HDR Analysis workflow additions, again in the SpectraCal suite. As I don't have an HDR test pattern generator currently, we've utilized madTPG for the HDR pattern generator. To note, in SDR mode the monitor reports a "SDR-BT1886" EOTF (gamma) instead of "SDR-sRGB" when in YCbCr mode, but in HDR mode the EOTF is "HDR-ST2084".
Checking back on HDR brightness, we see that the peak brightness is around 1236 nits, reached when a 10% area of the screen was white. So there's definitely room to spare with respect to the 1000 nit minimum requirement.
The HDR gamut coverage matches what we saw with the SDR 'wide gamut' mode, confirming that it covers around 76% BT.2020 and 92% DCI-P3.
Originally in delta ICtCp format, which reportedly describes HDR more accurately, the metrics are in delta E for ease of comparison. The HDR10 media profile targets the BT.2020 space, so it's important to see how well devices designed for the more limited P3 gamut do inside this subset. In that respect the PG27UQ is able to do quite well, with dE's below 3 on color saturation sweeps.
As for chroma subsampling, the 4:2:2 mode kicks into effect when in HDR mode at 120Hz or above. The lack of full horizontal color data can be noticed in certain cases, such as colored text on colored backgrounds where font can become blurry.

3840x1600 is the dell i mean.Impulses - Tuesday, October 2, 2018 - link
The Acer Predator 32" has a similar panel as that BenQ and adds G-Sync tho still at a max 60Hz, not as well calibrated out of the box (and with a worse stand and controls) but it has dropped in price a couple times to the same as the BenQ... I've been cross shopping them for a while because 2 grand for a display whose features I may or may not be able to leverage in the next 3 years seems dubious.I wanted to go 32" too because the 27" 1440p doesn't seem like enough of a jump from my 24" 1920x1200 (being 16:10 it's nearly as tall as the 16:9 27"erd), and I had three of those which we occasionally used in Eyefinity mode (making a ~40" display). I've looked at 40-43" displays but they're all lacking compared to the smaller stuff (newer ones are all VA too, mostly Phillips and one Dell).
I use my PC for photo editing as much as PC gaming but I'm not a pro so a decent IPS screen that I can calibrate reasonably well would satisfy my photo needs.

It is "almost" perfect. It is missing one of the most important things, HDMI 2.1, which has the bandwidth to actually feed the panel with what it is capable of doing (i.e. 4k HDR 4:4:4 120Hz). But we don't have that because this monitor was actually designed 3 years ago and only now finally coming to market, 6 months after HDMI 2.1 was released.lilkwarrior - Monday, October 8, 2018 - link
HDMI 2.1 certification is still not done; it would not have been able to call itself a HDMI 2.1 till probably late this year or next year.imaheadcase - Tuesday, October 2, 2018 - link
The 35 inch one has been canceled fyi. Asus rep told me when inquired about it just a week ago, unless in a week something has changed. Reason being panel is not perfect yet to mass produce.That said, its not a big loss, even if disappointing. Because HDR is silly tech so you can skip this generation

I bought one of these, just as they came out. Amazing display performance, but the in-built fan to cool the G-Sync HDR-module killed it for me.It's one of those noisy 40mm fans, which were otherwise banned from PC setups over a decade ago. It made more noise than the entirety of the rest of my 1080 Ti-SLI system combined. Like a wasp was loose in my room all the time. Completely unbearable to listen to.
I tried to return the monitor as RMA, as I thought that couldn't be right. But it could, said the retailer. At which point I chose to simply return the unit.
In my case, these things will have to wait, till nVidia makes a new G-Sync HDR module, which doesn't require active cooling. Plain and simple. I'm sort of guessing that'll fall in line with the availability of micro-LED displays. Which will hopefully also be much cheaper, than the ridiculously expensive FALD-panels in these monitors.

Can't you just replace the fan yourself? I read around the time of release someone simply removed fan and put own silent version on it.EAlbaek - Tuesday, October 2, 2018 - link
No idea - I shouldn't have to void the warranty on my $2000 monitor, to replace a 40mm fan.madwolfa - Tuesday, October 2, 2018 - link
Is that G-Sync HDR that requires active cooling or FALD array?EAlbaek - Tuesday, October 2, 2018 - link
It's the G-Sync HDR chip, apparantly.
