As the culmination of its CES 2020 gaming announcements, Acer has introduced its first big-format OLED display aimed at gamers. The Predator CG552K brings to the table everything that the OLED technology generally has to offer, and adds a 120 Hz maximum refresh rate along with variable refresh rate technologies supported by modern GPUs from AMD and NVIDIA.

Acer’s 55-inch Predator CG552K features a 3840x2160 resolution, 400 nits maximum brightness, and can display 98.5% of the DCI-P3 color gamut all with a calibration accuracy of Delta E<1. Since Acer uses an advanced OLED panel, they are able to offer not only a very high contrast ratio, but also extremely deep blacks, a 0.5 ms response time, as well as a 120 Hz refresh rate, one of the most important features for demanding PC gamers.

To take advantage of the high refresh rate, the Predator CG552K supports three (ish) variable refresh rate technologies, including HDMI 2.1 VRR (currently supported by Xbox One), VESA’s Adaptive-Sync (which means that the display will probably get AMD’s FreeSync certification), and NVIDIA G-Sync compatibility (which is likely piggybacking on HDMI-VRR).

Unfortunately, Acer says nothing about HDR10 or DolbyVision support for the Predator CG552K, so it appears that the display does not support any kind of HDRt, a clear disadvantage when compared to popular OLED TVs such as LG's G-Sync-compatible 2019 OLED UHDTVs.

In a bid to prevent burn-ins and prolong lifespan of the OLED monitor, Acer equipped it with sensors that automatically adjust brightness according to room’s light level and turn it off when nobody is around. Connectivity wise, the Acer Predator CG552K has two DisplayPort 1.4 connectors, three HDMI 2.0 ports, a USB Type-C input, and a couple of USB 2.0/3.0 ports. In addition, the display has two 10 W speakers.

    DOA without Dolby Vision HDR & HLG HDR. Especially vs. a LG C9 or C10 OLED HDMI 2.1 TV. WTF is Acer and any PC monitor manufacturer thinking omitting proper HDR formats on gaming monitors?!!!
  • lilkwarrior - Monday, January 6, 2020 - link

    It's pointless to have speakers on this when it can't even consume premium 4K home content correctly without Dolby Vision HDR, HLG HDR, & HDR10. Hopefully they give an update or their product research team are frankly morons.

    Do these kind of OLED displays suffer from the same ghosting issues at low brightness with black content as mobile OLED displays do?
  • lilkwarrior - Monday, January 6, 2020 - link

    No. mobile OLED processes are different than what LG & others do far large OLED panels (necessary as they MUST account for longer longevity w/ large OLED panels vs mobile OLED panels)

    2020 and still using HDMI 2.0... When are HDMI 2.1 displays going to be a thing? I am ready to upgrade from my Sony XBR43X800D 43" 4K that I use as my primary monitor to something newer, but I have been waiting for 120hz HDMI 2.1 displays to hit the market. It is shocking to me how long this has taken.

    TV makers are probably waiting for PS5 and XboxX so they can promote HDMI 2.1 as a big selling point to get people to upgrade.

    At this price, there is practically no reason not to just buy the equivalent LG OLED TV. The latter gives you HDMI 2.1, and can also be used as a TV.

    $3000 for a 55" OLED. GTFO, Acer.

    $1400 for the same damn thing.
