Update:
Well, it's arrived and I have to say, 4K @ 40" seems bl@@dy perfect, hopefully no more eyestrain and I can sell on the itsy bitsy 28" 4k TN Sammy (thanks for the correction PCM2)
Blacks look brilliantly black, whites look brilliantly white compared to the TN and the angles are way more forgiving.
Having had 2 curved 34" the past couple of weeks while I was deciding if I could live with IPS Glow and/or BLB (I couldn't), the vast screen of the Philips almost looks convex!
It's huge!
Much better motion than the Sammy in ArmA3 too and Elite D... well I knew space was big, but now it's even bigger
Going to try a few driving sims later on, but my guess is it won't beat my current 84" wrap-around screen in any way bar resolution, but I'll stick my TrackIR on and see anyway
Corners are a bit dimmer than the rest of the screen, no dead or bright pixels out of the box.
The stand is awful and the screen tilts back by a few degrees, so I've propped it up at the rear.
I need to get it closer to the desk though, that's for sure... so any stand recommendations?... just types/models, I'll source it myself to save breaking the forum etiquette.
Initial thoughts are very good, once I sort the stand I'll be happy (until they bring a curved version out OFC).
