Further information on supporting our work.The ultrawide experience can be very enjoyable – and so can viewing on OLED screens. The Acer Predator X34 F3 marries the two, featuring a refined QD-OLED panel and various improvements over older generations – such as a higher refresh rate, enhanced brightness and renewed subpixel arrangement. The monitor offers the usual aggressive styling associated with the Predator series, including a firmly-planted ‘penguin foot’ coated metal stand base. As usual dual-stage bezels are used at the top and sides, with black panel border plus hard outer component. A sensor unit integrated into the bottom bezel may allow functionality such as presence detection and adjustment of the image according to ambient light, although the exact functionality isn’t currently known.
A 34″ Samsung Display QD-OLED panel is adopted with 3440 x 1440 (21:9 ultrawide) resolution, a fairly gentle (1800R) curve and support for a 360Hz refresh rate. The monitor includes a vertical RGB stripe arrangement for subpixels, which panel manufacturer Samsung refers to as ‘V-Stripe’. This is designed to massively reduce or eliminate fringing issues caused by the traditional QD-OLED triangle RGB layout. The screen surface is glossy with anti-reflective treatment and according to panel manufacturer Samsung, this panel provides “40% deeper blacks” (i.e. less brightening up in ambient lighting) and “2.5x more scratch-resistance” compared to earlier generations. VRR is supported via Adaptive-Sync and HDMI 2.1 VRR, allowing technologies such as Nvidia ‘G-SYNC Compatible’ and AMD FreeSync Premium Pro to be used, with assumed 48 – 360Hz VRR range plus LFC. 178°/178° viewing angles, 10-bit colour and a 0.03ms grey to grey response time are specified. The monitor is ‘flicker-free’, with 300 cd/m² (1300 cd/m² HDR peak specified for panel) typical maximum luminance and 99% DCI-P3 colour gamut.
The monitor can provide a lively HDR10 experience and put its generous colour gamut, 10-bit colour and per-pixel illumination to good use. This model is VESA DisplayHDR True Black 500 certified – requiring higher brightness levels, including full screen white brightness, than the more common True Black 400 certification. Alternative higher brightness HDR modes allow stronger brightness peaks to be leveraged as well. The included stand offers tilt, swivel and a generous amount of height adjustment (150mm or 5.91 inches). Provision for 100 x 100mm VESA mounting is also included. The ports include DP 1.4, 2 HDMI 2.1 ports and an AC power input (internal power converter) – with 2 x 2W speakers included for basic sound output. Further details can be found in this press release, with the monitor due Q2 2026 for ~$1200 USD (Q3 2026 for ~€1200).
