The Acer Predator X27U X1, part number X1bmiiphx (UM.GXXEE.101), is a 27-inch (26.5-inch viewable) QD-OLED gaming monitor with WQHD 2560×1440 resolution, a 240Hz refresh rate and a 0.03ms GtG response time. Its Quantum-Dot OLED panel covers 99% of DCI-P3 with Delta-E <2 accuracy and true 10-bit colour, reaching a 1000-nit HDR peak with VESA DisplayHDR True Black 400. AMD FreeSync Premium Pro keeps fast-paced gaming tear-free, and two built-in 5W speakers cover everyday audio. It is one of the most aggressively priced 27-inch QD-OLED panels available. Typically in stock with fast delivery across Cyprus.
Good to know
To hit its competitive price, the X27U X1 has no USB ports / USB hub. Adaptive sync is officially certified as AMD FreeSync Premium Pro; variable refresh over DisplayPort/HDMI generally also works with NVIDIA GPUs, but G-SYNC Compatible is not officially listed by Acer.

Frequently Asked Questions
Does the X27U X1 work with PS5 and Xbox Series X?
Yes. Its two HDMI 2.1 ports support modern consoles, so the PlayStation 5 and Xbox Series X run smoothly. On a PC, both HDMI 2.1 and DisplayPort 1.4 drive the panel at the full 2560×1440 / 240Hz.
Does it have USB ports or built-in speakers?
It has no USB ports or USB hub - one of the trade-offs that keeps its price low. It does include two built-in 5W speakers for everyday audio, plus two HDMI 2.1 and one DisplayPort 1.4 input.
Does it work with NVIDIA graphics cards?
Yes. Acer officially certifies AMD FreeSync Premium Pro, and variable refresh over DisplayPort/HDMI generally also works with NVIDIA GPUs - though Acer does not officially list G-SYNC Compatible for this model.
What should I know before buying the X27U X1?
It is a glossy-style QD-OLED with no USB hub, AMD FreeSync Premium Pro certification, DisplayHDR True Black 400 (1000-nit peak), built-in speakers and an Ergostand with tilt/swivel/height (no pivot). OLED eye-care and flicker-free features are included.
Singular Expert Insight
The X27U X1 is one of the best-value ways into a 27-inch QD-OLED: you get the vivid colour, deep blacks and 240Hz speed of a premium panel, while Acer trims the price by leaving out a USB hub. If you don't rely on built-in USB ports, it is hard to beat for the money - just budget for a separate hub if you connect lots of peripherals.
Buyer's Guide
Buy it if
You want vibrant QD-OLED colour and 240Hz gaming at the lowest possible price, and don't need a USB hub.
Skip it if
You need built-in USB ports, a USB-C / KVM hub, officially certified G-SYNC, or a stand with pivot.
Also consider
Acer Predator X32 X2 for a 4K 240Hz QD-OLED, or a model with a USB hub if connectivity matters.
