MMD/Philips has announced three new gaming monitors that are also interesting for working with video: the huge 55 inch (142 cm) Philips Momentum 558M1RY, the 31.5 inch (80 cm) Philips Momentum 328M1R and the 27 inch (68.6 cm) Philips Momentum 278M1R.
The top model is the huge "55 Momentum" the size of a television with a 4K UltraHD resolution (3,840 x 2,160), FreeSync support, a frame rate of 120 Hz (when displayed in QuadHD) and real HDR according to www.slashcam.en/article/guidance/guidance-want-a-monitor-can-display-represent real-HDR--cautions-at-the-DisplayHDR-Standards.html (DisplayHDR 1000) VESA-specifications, i.e. it offers 10-bit color depth, a brightness of 1.000 nits (and is thus more than 3x brighter than normal monitors), local dimming as well as a color range of at least 99% of the BT.709-Color space and 90% of the DCI-P3 color space. 
Here our basic article for understanding color spaces.
Philips Momentum 558M1RY
The value of the highest brightness, however, always refers to small areas of the screen, not the entire surface - the specifications differentiate not only between the peak brightness of small areas and the entire screen surface, but also between short-term total brightness and the highest brightness that can be maintained over longer periods of time without overheating the display - this is 600 nits for DisplayHDR-1000, for example. The integrated sound system of the Philips Momentum 558M1RY was developed in the form of a sound bar in collaboration with audio specialist Bowers & Wilkins. The monitor has three HDMI-2.0 and one DisplayPort as well as a USB 3.2 Hub with four ports and adjusts the Ambiglow its closer environment in color to the respective content shown.

The Philips Momentum 278M1R 4K monitor is 27 inches in size with a refresh rate of 60 Hz and an HDMI 2.0 input - more is unfortunately not known.
