And back on topic:
I brought $500USD ($800 aupesos inc tax) worth of QHD monitor compromise just for the RGB on the backside eBay auction: #143355491458 Got it with evilbay discount for what I consider a good price, also in the mix was the soon to be released LG 27GL850-B which is a toss up between them for performance.
I think that's a good price for the mix of features: IPS, QHD, HDR, DCI-P3 color space, high refresh rate.
This week I also bought a new monitor, a Philips 326M6FJSB.
It is also QHD (2K) but 32" so it maintains the same-ish DPI as my previous FHD monitor. I paid less (~$300 USD) but everything other than size is lower spec that yours. No HDR, but color gamut is wide, just shy of DCI-P3. Refresh rate of 75 Hz isn't gamer-spec but works for me. My somewhat older RX480 video card can still push all those pixels at 55 to 75 FPS (SW Battlefront 2) and with Freesync, it looks smooth as butter to me. It has "Ambiglow" which is a row of RGB LEDs under the monitor to provide ambient light matching the dominant colors on-screen. Gimicky, but I have not turned it off yet. I had chosen this monitor for the wide gamut, IPS panel, but I really like the Freesync feature that I didn't know I needed until I saw the huge difference it makes. I had also tried an LG 32" 4K monitor with a VA panel (also DCI-P3 color), but found the colors became too washed-out off-center and couldn't get over that so I returned it.
