At CES 2020, Acer introduced the Predator CG552K, a 55" OLED monitor with UltraHD resolution, specially designed for gaming - but its technical specifications also make it interesting for some video editing applications. It covers the professional DCI-P3 color space to 98.5%, has a color accuracy of Delta E < 1 and complies with the DisplayHDR400 standard, i.e. it can display up to 400 nits bright for short periods of time. It supports variable refresh rates (VRR) via Adaptive Sync and NVIDIA G-SYNC with up to 120 Hz. Unfortunately, its DisplayHDR400 support 
probably not is sufficient to display real HDR.

An integrated light sensor measures the ambient brightness and dynamically adjusts the screen brightness accordingly. The CG552K uses a proximity sensor to detect if someone is sitting in front of it and switches itself on or off accordingly to save energy. Its interfaces include three HDMI 2.0 ports, two DisplayPorts 1.4, one USB-C port, two USB 2.0 and two USB 3.0 interfaces. Potential buyers will have to be patient, though: the Predator CG552K is not expected to be launched on the German market until the third quarter of 2020 at a price of around 2,700 euro.
