Acer Predator X34 F1 — 34″ Curved QD-OLED Ultrawide Gaming Monitor

360 Hz QD-OLED3440 × 1440 UWQHD0.03 ms GTG2× HDMI 2.1 + USB-C

The Acer Predator X34 F1 (part number UM.CXXEE.105) is a 34-inch 1800R curved QD-OLED ultrawide gaming monitor with a 3440 × 1440 resolution, built for PC gamers who want OLED contrast and a very high refresh rate on one wide screen. Each pixel produces its own light, so blacks are truly black and Acer rates the native contrast at 1,500,000:1, while the quantum-dot layer covers 99% of the DCI-P3 cinema colour space. Response time is 0.03 ms grey-to-grey, which is why motion looks crisp even in fast shooters. The same monitor doubles as a desk hub: USB-C input, two USB Type-B upstream ports for the built-in KVM switch and 10 W speakers mean a laptop and a gaming PC can share one keyboard, mouse and screen.

Compatibility — check before buying:
Graphics card first: 3440 × 1440 at 360 Hz is a heavy load — to actually see high frame rates in modern games you need a strong current graphics card. Inputs: 2× HDMI 2.1, 2× DisplayPort 1.4 and 1× USB-C. Acer does not publish a per-input refresh table for this part, so if you plan to connect a console or a laptop over USB-C, tell us the model and we check what it will run. USB-C charging: Acer’s X34 QD-OLED product page states 65 W power delivery — laptops that draw more than 65 W will charge slowly or not at all over this cable. Stand: height, tilt and swivel only — no pivot. OLED care: like every OLED, avoid leaving static bright images on screen for many hours.

Best For

✓ Competitive and single-player PC gaming on an ultrawide screen
✓ Racing and flight simulators that benefit from 21:9 field of view
✓ HDR films and series on true OLED blacks
✓ A two-computer desk with the built-in KVM switch

Key Features

 
QD-OLED at 360 Hz
Self-emissive pixels give per-pixel contrast and a 0.03 ms GTG response, and Acer’s X34 QD-OLED page lists 360 Hz — smooth motion with no backlight blooming around bright objects.
 
1800R ultrawide curve
3440 × 1440 on 34 inches (0.231 mm pixel pitch) with a gentle 1800R curve that keeps the edges of the 21:9 image at a comfortable viewing angle.
 
Desk hub with KVM
USB-C input plus two USB Type-B upstream ports and USB 3.2 downstream let the monitor switch one keyboard and mouse between two computers.
 
Colour and sound built in
99% DCI-P3 and Acer’s DisplayHDR 500 True Black rating for the X34 QD-OLED line, plus 10 W speakers, headphone and line-out jacks.

Frequently Asked Questions

Will my graphics card reach 360 Hz at 3440 × 1440?
Only a powerful current graphics card will push modern games close to 360 frames per second at this resolution; mid-range cards will run lower frame rates, which the monitor still displays smoothly thanks to FreeSync Premium Pro and G-SYNC Compatible. Tell us your graphics card and the games you play and we tell you what to expect.
Can I charge my laptop through the USB-C cable?
Yes, within limits. Acer’s X34 QD-OLED page lists 65 W USB-C power delivery, which suits most ultrabooks. Gaming laptops that need 100 W or more will not charge properly this way — keep their own charger connected.
Is burn-in a concern with QD-OLED?
Every OLED can retain an image if the same bright static content stays on screen for very long periods. Using a dark taskbar, a screen saver and not leaving static HUDs on for hours keeps the risk low. Acer does not publish burn-in coverage on this model’s EU page.
What is in the box?
The monitor with its stand, an EU power cord, one DisplayPort cable, one HDMI cable, one USB Type-C cable and one USB 3.0 cable. A wall mount is not included; the monitor accepts any 100 × 100 mm VESA arm. If you are not sure which cable your graphics card or laptop needs, send us its model and we check it before you order.
Singular Expert Insight
The X34 F1 sits at the top of the ultrawide gaming screens we list: QD-OLED contrast plus 360 Hz on a 21:9 canvas is a combination IPS and VA panels cannot match. If you play mostly competitive shooters on a flat 27-inch field of view, the Predator XB273U F5 gives you 360 Hz for far less money; if you want OLED for films and single-player games, this is the one. Browse all our PC monitors, or pair it with a stronger card from our graphics cards range to make full use of the refresh rate.

Buyer’s Guide

Buy it if

You play on PC with a strong graphics card, want OLED blacks, 360 Hz and a 34-inch 21:9 curve, and like the idea of one screen with KVM for work and play.

Skip it if

You mostly leave static content (spreadsheets, trading terminals) on screen all day, or your laptop needs more than 65 W over USB-C. A flat 27-inch screen also takes far less desk depth than this 34-inch curve.

Also consider

Acer Predator XB273U F5 — 27″ IPS, 360 Hz and NVIDIA G-SYNC Pulsar for esports at a much lower cost.
