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.

That's really bad as there is no any product which support DP 2.0 so we stucked with DP 1.4 with fake 144Hz So all monitors and TVs are obsolete... Only laptops which has 144 or 240 or 300Hz has real refresh rate as there is no any HDMi or DP but nobody talking about eDP (embeded display port) which is in laptops and which is in reality supported up to 120Hz so how on earth they making laptops with 144Hz or 240 or even 300Hz ???
