Further information on supporting our work.OLED technology is compelling for a gaming monitor due to the combination of strong responsiveness and image quality. The Acer X27U of the Predator series provides this experience, with OLED technology driven at a 240Hz refresh rate and QHD resolution. The monitor provides very slim bezels at all sides; but the press image below is misleading in this respect as it seems to have the image super-imposed to hide part of the panel border (for reference, the LG 27GR95QE shares the same panel). This border is flush with the rest of the screen and forms part of the dual-stage bezel design – there’s also a slim hard plastic outer component. The stand includes brushed metal with a slightly rounded variation of the company’s ‘Dragon Claw’ design. From what we can see in the image, the OSD (On Screen Display) is controlled by a joystick beneath the central region of the bottom bezel.
A 26.5″ 2560 x 1440 (QHD or 1440p) LG Display RWBG OLED panel is used with matte anti-glare screen surface, 10-bit colour, 178°/178° viewing angles and support for a 240Hz refresh rate. Adaptive-Sync also features, including AMD FreeSync Premium with assumed 48 – 240Hz VRR range plus LFC. The monitor is flicker-free with Eyesafe certification owing to the peak of blue light being shifted to less energetic wavelengths to aid viewing comfort. The monitor has a specified typical maximum luminance of 150 cd/m² – this will depend on the APL (Average Picture Level) or how much of the screen is showing bright vs. dim content. A 98.5% DCI-P3 colour gamut is specified, whilst the monitor can put this to good use for HDR10 content alongside its per-pixel illumination, 10-bit colour support and 1000 cd/m² peak luminance (3% white).
A grey to grey response time of ‘up to 0.01ms’ is specified; as usual pay little attention to such figures, though OLED technology is known to be strong in this respect. The stand is expected to offer tilt, swivel and height adjustment at a minimum with provision for 100 x 100mm VESA mounting. The ports include; DC power input (external ‘power brick’), DP 1.4, 2 HDMI 2.0 ports, USB-C (90W PD, DP Alt Mode, upstream data), 2 USB 3.2 Gen1 ports (plus 2 Type-B upstream) and 3.5mm audio output. 2 x 5W speakers are included, with the monitor supporting KVM for easy display input switching and USB peripheral sharing with multiple systems. Further details in this press release. The monitor is expected from Q2 2023 in the EU and US for ~$1100 USD (~€1100).
