My C2 42" arrived yesterday from Mr Lewis, very happy so far!
Not run specific uniformity tests yet, bit hesitant to do them as so far not noticed any uniformity issues at all since using it. Will do soon to make sure as it's the sensible thing to do in case at some point I do notice something in general use, but for now ignorance is certainly very blissful!
Just 2 issues so far:
When waking my PC or booting it up (3070) I'll almost always get the 'No Signal' screen when using 120hz HDR and 'HDMI Deep Colour' setting on the TV. Have to switch 'HDMI Deep Colour' back and forth a good few times until eventually it decides to work.
Pretty annoying, tried a couple things like a suggestion of disabling 'Fast Boot', turned PC sleeping to Never, but doesn't seem like there's any workaround currently
Seems to be a common one going back to the CX series from googling.
The VRR flicker on grey backgrounds is certainly noticeable and painful when you see it happening. Only noticeable when the framerate is fluctuating heavily, which in games is rare but certain loading screens and game menu screens make it go wild.
Colours are gorgeous though, and already starting to love the size (came from a 27") having a few nice big windows open around the screen. Only really notice the brightness dimming when I fullscreen a small bright window, which hopefully I wont be doing too often.
Definitely need a bigger desk for this thing mind, bit too close with my current one.
