I got this AW3423DW for around 1625 Euros (early morning order).
You should cancel your orders asap. It's absolutely trash. I had an 1000 Euro 2nd order open, i canceled it too after testing.
Negative aspects:
-colors are broken (looking wrong like va colors) and washed out compared with LG nano ips
-the screen has an very annoying silver/white glow
-the fan/s are very loud
-near black flickering
-vrr flickering
-green/magenta artefacts (bad pixelrendering)
-bad sharpness/fuzzy text/picture, looks like crappy bgr pixelrendering, compared with nano ips with same ppi absolute trash
-glossy surface, any enviroment light is causing massive distraction and defocusing
-mine has two subpixel failures, magenta on white background and green on black background
-hdr 1000 peak mode much worse than hdr 400 true black mode, abl is much more aggressive
-motion not as smooth and sharp as nano ips (LG 34GP950G), oled juttering + 5 ms btg transitions (no joke a tester measured it), lg wrgb oled is much better
-some models with scratches on ar coating due no film protection
-every 4 hours pixel refresh for multiple minutes
Positive aspects:
-hdr looks fairly good in hdr 400 true black mode
-contrast is very good
-no blb
-no halos
