The 21:9 experience can be very appealing in terms of immersion and enhanced Field of View during gaming. The Acer Predator X34 X5 provides this, with an OLED screen offering strong image quality and responsiveness. The monitor adopts sharp-lined styling, with dark grey coated metal tripod-style stand base and mixed grey and black elements along the neck. 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 the ‘screen move’ feature, one of the ‘OLED screen protection’ mechanisms. The OSD (On Screen Display) is controlled by a central joystick at the rear of the screen, behind the bottom bezel.

A 34″ 3440 x 1440 (21:9 ultrawide) Samsung Display QD-OLED panel is used with 240Hz refresh rate and VRR, including Adaptive-Sync (and presumably HDMI 2.1) supporting technologies such as Nvidia ‘G-SYNC Compatible’ and AMD FreeSync Premium Pro. A 48 – 240Hz VRR range plus LFC is assumed. The usual glossy QD-OLED screen surface is expected, with additional points of note including a 1.5m:1 static contrast ratio, 178°/178° viewing angles and 10-bit colour. A 1800R (moderate) curve is included to draw you into the experience a bit without feeling unnatural. The screen is flicker-free with 99% DCI-P3 (plus strong Adobe RGB coverage – no value specified) colour gamut and 250 cd/m² typical maximum luminance (1000 cd/m² HDR peak, 3% window). A factory calibration is included with specified DeltaE <1.

The monitor provides HDR10 support with the usual dynamic QD-OLED experience expected – including per-pixel illumination, 10-bit colour and the generous colour gamut being put to good use. Some good brightness bursts can be outputted under HDR as well. A 0.03ms grey to grey response time is specified – pay little attention to the exact figure, though OLED technology is known for its exceptional pixel responsiveness. The stand attaches centrally via a quick-release mechanism and offers tilt, swivel and a generous 150mm (5.91 inches) height adjustment. Provision for 100 x 100mm VESA mounting is also included. The ports face downwards and include; AC power input (internal power converter), 2 HDMI 2.1 ports, DP 1.4 (with DSC), USB-C (90W PD, DP Alt Mode, upstream data), a 3.5mm audio output and 2 USB 3.2 Gen 1 ports plus Type-B upstream. KVM is supported for easy sharing of connected USB peripherals and display input switching between 2 systems. 2 x 5W speakers are included for potentially fairly rich sound output.
