A 43"/144Hz/HDR option which is likely to be a lot cheaper than these 32" Gsync ones:
VA panel is a let down though.
The ASUS XG438Q already was awful: BGR subpixels for blurrier text, bad overshoot and black smearing issues. The Acer CG7 uses the same panel as the Asus PG43UQ and doesn't seem to be much better. The HDR1000 is a joke when it has very limited local dimming capabilities. Best case scenario is that AUO has improved the panel or Asus has managed to improve control of it for no overshoot and good enough dark transition times.
On paper this is a really sweet monitor but if you consider the LG 48" OLED is better in pretty much every metric (if they don't fuck it up and make it 60 Hz only or some bullshit) and not absurdly larger this might turn out to be yet another disappointing monitor.
It does have a picture by picture mode which I like, it's really unfortunate that no TVs offer that when they have the size and resolution that would be perfect for splitting the screen 2 or even 4 ways.
