Further information on supporting our work.The 21:9 aspect ratio provides a rewarding and immersive experience on a 34-35″ screen. With its 38″ 21:9 UltraWide panel, the Acer X38 S (X38 Sbmiiphzx) takes this even further. As a member of the Predator series, the screen has an aggressive sharp-lined appearance. The stand base includes two prominent feet, powder-coated metal which also runs around the edge of the stand neck. The top and side bezels are dual-stage, with a slim panel border flush with the rest of the screen. And a slender hard plastic outer component. The OSD (On Screen Display) is controlled by buttons and a joystick at the rear of the screen, running down the right side as viewed from the front. A light sensor which we believe is located at the top of the monitor provides ‘LightSense’ and ‘ColorSense’ functionality. This allowing the screen to adjust its brightness and colour temperature, respectively, based on ambient lighting.
A 37.5″ LG Display Nano IPS UltraWide panel is adopted, with 3840 x 1600 (21:9) resolution and 2300R curve. Designed to draw you in a bit, without feeling unnatural. A 175Hz refresh rate is supported (144Hz + factory overclock), whilst a G-SYNC module provides the full G-SYNC Ultimate experience. This includes seamless operation over the full VRR range and support for variable overdrive – tuning of the pixel responses over a broad range of refresh rates. To minimise overshoot. Other aspects of note include a 1000:1 static contrast ratio, light matte anti-glare screen surface with relatively smooth finish, 178°/178° viewing angles and 10-bit colour support (8-bit + FRC). A flicker-free WLED backlight offers a 98% DCI-P3 colour gamut and typical maximum luminance of 450 cd/m². The monitor supports VESA DisplayHDR 600, including a peak luminance boost to 750 cd/m² and a degree of local dimming (edge-lit rather than FALD). The colour gamut and 10-bit colour output can be used appropriately here, too. A factory-calibrated sRGB emulation setting with a claimed DeltaE <1 is included.
A 1ms or ‘up to 0.3ms’ grey to grey response time is specified, to be approach with caution. A ‘G-SYNC Esports mode’ is included, aimed at competitive gaming with a focus on minimal latency and high visibility – ‘Variable Backlight’ local dimming is disabled and gamma enhancement is used to lighten up dark shades, revealing extra detail. Nvidia’s Reflex Latency Analyzer is also supported, allowing users with compatible hardware to get an accurate idea of overall system latency. The stand attaches centrally with a quick-release mechanism. 100 x 100mm VESA is supported, whilst the included stand offers; tilt, height (130mm or 5.12 inches)and swivel adjustment. The ports mainly face downwards and include; DC power input (external ‘power brick’), 2 HDMI 2.0 ports, DP 1.4, 3.5mm audio output and 4 USB ports (1 x 2.0, 3 x 3.0) plus upstream. 2 of the USB ports are found at the left side as viewed from the front. 2 x 7W speakers are included for potentially quite rich and powerful sound output.
Further details can be found on the this press release. The monitor is listed for ~$2000 USD (~€2200).
