There are a few reviews out/publish online.  All positives.

H-IPS, fast pixel response, Minimal lag (arount 10 to 20ms), excellent colour reproduction, each panel calibrated before leaving factory (with documentation).  Wide colour gamut without saturating colours. Potentially a panel which is more than 8bit of shades per sub-pixel (A 10-bit panel, with 1.07 Billions of colours, instead 16.7 mil.)

Nice touch sensitive buttons.
Switching inputs require more effort than single button push of previous 24" ultras.
There is a slight delay in powering up after switching on (about 5 sec)
About 2 sec delay from waking up from display power safe mode.
Mine has no dead/stuck pixels.
