Update: The Acer Predator XB273K can run 4K, 144Hz, and HDR simultaneously without any compression. This is achieved by connecting the monitor via two DisplayPort 1.4 cables/ports.
However, this way, the G-SYNC range is limited to 30-120Hz at 4K due to the limitations of the bandwidth provided by a single DisplayPort 1.4. You can still use G-SYNC with a 48-144Hz range at 1440p.
Acer has announced a more budget-friendly 4K 144Hz gaming monitor dubbed as the Acer Predator XB273K.
The full-array local dimming of the X27 4K 144Hz monitor consists of 384 individual zones which help control the backlight for the best image quality. Moreover, it has a peak luminance of over 1,000-nits, a superior static contrast of 20,000:1, and a wide color gamut for HDR content. All of that accumulated to its exceptional high price.
The Acer XB273K, on the other hand, will feature only a few dimming zones and a peak brightness of 400-nits. So, the image quality won’t be nearly as vibrant and impressive, but you will still have 4K 144Hz, a limited HDR support, NVIDIA G-SYNC, and a wide color gamut of 100% sRGB and 90% DCI-P3.
Just like the X27, the Acer Predator XB273K will require at least a GTX 10xx series GPU with a DisplayPort 1.4 connector for native 4K at 120Hz.
For 4K and 144Hz, the display will have to use two DisplayPort 1.4 connectors.
The Predator series monitors include nifty gaming features such as customizable crosshairs, pre-calibrated gaming picture presets, and the ‘Dark Boost’ feature for better visibility in dark parts of games.
Furthermore, the Acer Predator XB273K 4K 144Hz gaming monitor supports NVIDIA G-SYNC technology which allows you to synchronize the monitor’s refresh rate with a compatible graphics card’s frame rates.
As a result, screen tearing and stuttering is completely eliminated within the dynamic refresh rate range which amounts to 30Hz-120Hz at 4K and 30Hz-144Hz at 1440p.
Design & Connectivity
The Acer Predator XB273K boasts the Acer ErgoStand with full ergonomic support including tilt, height, swivel, and pivot adjustments as well as VESA mount compatibility.
Connectivity includes two DisplayPort 1.4, a quad-USB 3.0 hub, and most likely an HDMI port. The monitor also includes a shielding hood for minimal distractions while gaming.
Price & Similar Monitors
The Acer Predator XB273K price is $1,299 MSRP which is significantly lower than the $1,999 Acer Predator X27.
Keep in mind that a similar 4K 144Hz DisplayHDR 400 monitor will be available with FreeSync instead of G-SYNC which is the Acer Nitro XV273K priced at $899 MSRP.
Finally, the Acer XB273K release date is set for Q4 2018/Q1 2019.
