Received today and up and running.
First impressions are very good. Size, resolution and aspect ratio are absolutely perfect for me, as I knew they would be.
Image quality is excellent and the curvature is pretty much perfect for my viewing distance.
Note that, despite an advertised curvature of 1000R, this screen is not a section of a circle but instead has a tighter curvature in the centre and less at the sides. It works well though.
The panel looks pretty good to me. I was concerned/interested with the move to VA as I've typically chosen IPS but the colour reproduction looks as good as my old IPS Alienware.
One area VA suffers in a bit compared to IPS is off-axis backlight leakage and you can see this with such a large panel when you move your head around but, in everyday use, it's not that noticeable.
HDR is pretty meh at only HDR600 but frankly I don't really care.
Yes I know it's never going to get anywhere near an OLED for contrast and colour reproduction but then an OLED won't compete on text clarity or image retention so it all depends on your use-case.
All in all it's pretty much perfect for me. If and when a similar size/res/aspect IPS Black panel monitor arrives then I may well consider switching but, until then, it'll more than suffice and it's a bargain at £700!
