The Acer X45 aims to provide an immersive and responsive gaming experience, with its large 240Hz OLED panel. This member of the Predator series offers familiar ‘aggressive’ styling shared with others in the series, with a subtle curve added to the coated metal stand. The top and side bezels are dual-stage with slim panel border flush with the rest of the screen plus slim hard plastic outer component. The press image below includes an image superimposed over the monitor which hides the panel border, the LG 45GR95QE shares the panel and shows the panel border which the Acer also includes. From this image it appears the OSD (On Screen Display) is controlled by a joystick beneath the central region of the bottom bezel.
A 44.5″ 3440 x 1440 (21:9 ultrawide) LG Display WRGB OLED panel is adopted, providing a similar pixel density to a 27″ FHD model, ~84 PPI in this case. The monitor has an aggressive 800R curve, drawing you into the experience and arguably making the screen more practical for use at the desk given its considerable width. A matte anti-glare screen surface with low ‘glare rating’ (UGR <22) is included, whilst 178°/178° viewing angles and 10-bit colour support is specified. The monitor supports a 240Hz refresh rate alongside AMD FreeSync Premium, with assumed 48 - 240Hz VRR range plus LFC. The screen is flicker-free and is Eyesafe certified due to the peak of blue light being shifted to less energetic wavelengths, potentially aiding viewing comfort. A 98.5% DCI-P3 colour gamut is specified alongside a 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. The monitor can respond dynamically to HDR10 content, with 10-bit colour support and the gamut put to good use. And importantly, with per-pixel illumination and a peak HDR luminance of 1000 cd/m² (3% white) providing a good contrast experience.
A grey to grey response time of ‘up to 0.01ms’ is specified, which as usual should be taken with a pinch of salt. OLED technology is known to be strong when it comes to pixel responsiveness, however. The stand is expected to include tilt, height and swivel (possibly pivot) adjustment. It can be removed to reveal provision for VESA mounting with 200 x 100mm VESA holes. 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 for potentially reasonably rich sound output. The monitor also supported KVM for easy display input switching and USB peripheral sharing between multiple systems. Further details in this press release. The monitor is expected from Q2 2023 in the EU and US for ~$1700 USD (~€1800).
