For PC monitors the CHG70 is already miles ahead of most "gaming" monitors.
Many of those don't even run true 8-bit instead runs 6-bit + FRC rubbish.
Another issue with HDR on PC is problems with color mapping, if not done properly HDR mode will look WORST than SDR.
It also doesn't help that in order to watch HDR on youtube you need to turn on some flags in M$ Edge that is off by default.
Few games actually runs Freesync 2 HDR, and the color mapping on nVidia GPUs for HDR is IMO crap.
Especially seeing the rip-off 4k 144hs "HDR1000" G-Sync monitor from Asus in person, the HDR with that on BF5 (which is an RTX game) is absolute garbage.
Oh and don't get me started with the HDR on Anthem, it often bugs out and the Gamma goes through the roof instead of 2.2~2.4.
Miles ahead of most gaming monitors in HDR maybe - It's still bad HDR tho - Everything else about it is mediocre if you ask me. Not much of a gaming monitor IMO. I have tested tons of VA, IPS and TN gaming monitors over the past 8-10 years. VA have never impressed me in faster paced games. The slow pixel response time continues to be a problem for this tech.
The blur on CHG70, even at fastest mode with low input lag enabled, is way too much compared to even IPS/AHVA high refresh rate panels.
Pixel response is simply too high, especially in dark scenes. Too much smearing. Playing fast paced games is still a problem.
I was playing Apex Legends side-by-side with PG279Q and the difference in smoothness and responsiveness were simply huge.
Oh, I still have the CHG70 standing on the floor here. I will test it some more over the next days, vs Dell's new S2719DGF and Asus PG278QR, two 8 bit TN 1440p monitors.
So far tho, CHG70 does not have the nice black levels good VA monitors usually have. I remember testing Eizo FG2421, it had much better blacks and colors in general (also 1:5000 contrast). Failed in other aspects tho (pixel response time especially... once again and small size/res)
I like VA panels for TV's, if you don't need good viewing angles, but for PC gaming I would not recommend them, unless you are playing slower paced games or can accept some blur/smearing. It's good enough for RPG's, MMO's etc. It has some issues with text sharpness tho (because of how subpixels are generated), this is true for all Samsung and AUO VA panels.
In the end there's no perfect monitor. This is why I like to keep testing new monitors.
6 bit + FRC is typically low-end TN. There's many true 8 bit TN (mostly 1440p), there's also alot of true 8 bit high refresh rate IPS/AHVA panels and also some 8 bit + FRC.
These 8 bit 1440p TN panels have way better image quality than those cheap 6 bit + FRC 1080p TN panels.
