    I have an LG 4K Ultrafine on order, and just found it on the LG website:

    Once you dig through the marketing jargon and get down to the tech specs:

    - Screen Size 21.5" Flat
    - Panel Type IPS
    - Color Gamut (CIE 1931) DCI-P3 99%
    - Color Depth (Number of Colors) 8bits, 16.7M
    - Pixel Pitch (mm) 0.11622 mm × 0.11622 mm
    - Response Time 12ms / 14ms GTG
    - Refresh Rate H-Frequency: 88~143kHz V-Frequency: 48~60Hz
    - Aspect Ratio 16:9
    - Resolution 4096 x 2304
    - Brightness 500 nits
    - Contrast Ratio 1200:1
    - Viewing Angle 178 / 178
    - Surface Treatment Anti-glare, 2H

    Now this is mostly just what Apple quoted during their presentation. However, one thing caught my eye.

    12ms / 14ms GTG response time!

    All other high end IPS monitors i've seen have been in the region of 4-6ms.
    An example: LG 27UD88-W 5ms. http://www.lg.com/us/monitors/lg-27UD88-W-4k-uhd-led-monitor

    Won't that make the whole thing a blurry mess when there's lots of movement on screen (like when scrolling)? Anyone care to share their experience with it and comment on whether it's a problem or not?

    Haven't noticed any issues like that at all with mine. Note these panels are almost identical to those that have been shipping in the iMac for over a year (I think the UltraFine ones are brighter) and no-one complained about them.
