Further information on supporting our work.OLED monitors offer strong colour reproduction, contrast and response time characteristics. This makes them very attractive for uses such as gaming, something the Acer Predator X27 X (for when one ‘X’ isn’t enough) is designed for. The monitor offers familiar Predator styling, including a ‘penguin foot’ coated metal stand base and extensive use of dark matte plastics elsewhere. The top and side bezels are dual-stage, with slim panel border flush with the rest of the screen plus thin hard plastic outer part. An ‘active area’ (overprovisioning of pixels) between the image and panel border is used for one of the image retention mitigation measures. The OSD (On Screen Display) is controlled by a central joystick beneath the bottom bezel.
A 26.5″ Samsung Display QD-OLED (Quantum Dot OLED) panel is adopted with 3840 x 2160 (‘4K’ UHD) resolution and 240Hz refresh rate. VRR support is also offered, including Adaptive-Sync and presumably HDMI 2.1 VRR. This allows VRR technologies such as Nvidia ‘G-SYNC Compatible’ and AMD FreeSync Premium Pro to be used, with 48 – 240Hz VRR range plus LFC assumed. A 120Hz ‘4K’ UHD signal can also be used on modern consoles such as the PS5 and Xbox Series X. The usual glossy anti-reflective QD-OLED screen surface is used, whilst the monitor has a specified 1.5m:1 static contrast ratio, 178°/178° viewing angles and 10-bit colour support. The screen is ‘flicker-free’ with 99% DCI-P3 colour gamut and 300 cd/m² typical maximum luminance (1000 cd/m² HDR peak at 3% APL).
VESA DisplayHDR True Black 400 certification is included in addition to higher brightness HDR settings, providing a lively HDR experience. The monitor can puts its per-pixel dimming, high brightness peaks, 10-bit colour support and extensive colour gamut to good use for HDR10 content. The monitor is factory calibrated with a DeltaE <2 and has a specified 0.03ms grey to grey response time - OLED technology is known to be particularly strong in this area. The stand attaches centrally via quick-release mechanism and can be removed to reveal provision for 75 x 75mm VESA mounting. The included stand offers full adjustability, including height (150mm or 5.91 inches) adjustment and pivot into portrait. The ports face backwards beneath the stand attachment point and include; DC power input (external 'power brick'), 2 HDMI 2.1 ports, 2 DP 1.4 ports (with DSC) and a 3.5mm headphone jack. 2 x 2W speakers are also included for basic sound output.
The monitor is due for release Q3 2025 for ~$1100 USD (€1100, £1000).
