BenQ EX271UZ 27" 4K 240Hz MOBIUZ QD-OLED Gaming Monitor
PRODUCT DESCRIPTION
BenQ EX271UZ 27" 4K 240Hz MOBIUZ QD-OLED Gaming Monitor (EX271UZ) - 3 Year Local Warranty
4K Across 26.5 Inches — 166 PPI of QD-OLED Detail
The EX271UZ packs 3840 x 2160 into a 26.5-inch QD-OLED panel, which works out to 166 pixels per inch. That density is high enough that text edges and in-game texture detail stay clean at normal desk distance, and it is the reason this model suits a desk where the screen sits close rather than across a living room. BenQ rates the panel at 99% DCI-P3 with 1.07 billion display colours, 1,500,000:1 native contrast and VESA DisplayHDR True Black 400, with peak HDR brightness of 1000 nits against 250 nits typical in SDR.
240Hz at 0.03ms — Motion Clarity Without Overdrive Artefacts
Self-emissive pixels switch in 0.03ms grey-to-grey, so the trailing smear and inverse-ghosting halos that come with LCD overdrive tuning simply do not appear. Paired with a 240Hz refresh ceiling and FreeSync Premium Pro, frame delivery stays synchronised and tear-free even when frame times move around. Motion Blur Reduction is available for players who want a further step in clarity, while Colour Vibrance and Light Tuner adjust saturation and shadow lift per title from the on-screen menu or the supplied remote.
HDMI 2.1 with eARC, 90W USB-C and a Built-In KVM
Two HDMI 2.1 inputs are fitted, one carrying Enhanced Audio Return Channel so console and PC audio can pass back out to a soundbar or receiver. DisplayPort 1.4 handles a desktop GPU, and the USB-C input combines DisplayPort Alt Mode with 90W Power Delivery so a laptop runs video, data and charging down one cable. The built-in KVM switch moves a single keyboard and mouse between the connected machines — the feature that lets one 27-inch screen genuinely serve both a work laptop and a gaming PC.
Built to Last as an OLED, Not Just to Look Good on Day One
BenQ supplies the EX271UZ with a factory calibration report and layers its OLED protection suite underneath: Pixel Refresh to balance luminance, Pixel Shift to prevent uneven wear, and Idle Dimmer and Logo Dimming to reduce static-image stress. Firmware updates run from the monitor over USB. For a Singapore home office or studio where the same screen handles spreadsheets by day and games at night, those background protections are what make an OLED a sensible everyday panel rather than a weekend one.

Compatibility & Installation
Mounting
The stand tilts -5° to 15°, swivels 15° each way and gives 100 mm of height adjustment. The rear carries a 100 x 100 mm VESA pattern, and the panel is 5.14 kg without the base — light enough for any standard single-monitor arm, and easy to place over a dense desk.
What it connects to
Two HDMI 2.1 ports (one with eARC), one DisplayPort 1.4, and one USB-C carrying DisplayPort Alt Mode with 90W Power Delivery. A PS5 or Xbox Series X runs 4K at high refresh over HDMI 2.1, a desktop GPU is best on DisplayPort, and a USB-C laptop charges while driving the display. Downstream there are two USB Type-A ports, one USB Type-C port and a headphone jack.
KVM and multi-machine desks
The built-in KVM switch lets a single keyboard and mouse plugged into the monitor control whichever attached machine is on screen. Use the USB-C input for one computer and the USB Type-C upstream port for the other.
Console audio
The eARC-capable HDMI 2.1 port passes audio out to a soundbar or receiver, and a remote control is supplied in the box. BenQ's console feature set on MOBIUZ covers Auto Low Latency Mode, Variable Refresh Rate and Consumer Electronics Control.
Software
Colour Shuttle supplies game-specific colour profiles and Display QuicKit brings monitor settings onto the desktop. Firmware updates are applied over USB.

Frequently Asked Questions — BenQ EX271UZ
What do I actually gain moving from the EX271U to the EX271UZ?
The Z suffix marks the QD-OLED panel. The EX271U is an IPS LCD with an LED backlight: 1200:1 native contrast, 1ms GtG, 165Hz. The EX271UZ is self-emissive: 1,500,000:1 native contrast, 0.03ms GtG and 240Hz. In practice that means true blacks with no backlight glow in dark scenes, near-instant pixel response with none of the overdrive smearing an LCD carries, and a wider 99% DCI-P3 gamut against the EX271U's 95%.
What are the trade-offs of choosing the OLED?
Three worth knowing. The EX271UZ uses a glare (glossy) coating rather than the EX271U's matte finish, so a window or lamp behind you reflects more visibly. Typical SDR brightness is 250 nits against the EX271U's 400 nits, so a very bright room favours the LCD. And an OLED needs its static-image protections — Pixel Refresh, Pixel Shift, Idle Dimmer and Logo Dimming are all built in and should be left enabled. If your desk faces strong daylight all day, the LCD is the easier room fit.
Is 26.5 inches at 4K too small to see the detail?
At 166 PPI this is a dense panel. Windows and macOS scaling will typically be used rather than running at 100%, and the benefit shows as smoother text and finer texture detail rather than more desktop space. If you want the extra desktop area at 4K, the 31.5-inch EX321UZ gives the same resolution at 140 PPI.
Does it have built-in speakers?
BenQ does not list built-in speakers for the EX271UZ. There is a headphone jack, and the HDMI 2.1 eARC port passes audio out to a soundbar or AV receiver.
How does it compare with the EX271QZ?
The EX271QZ uses the same 26.5-inch QD-OLED chassis at 2560 x 1440 and 500Hz. Pick the EX271UZ for resolution and detail at 240Hz; pick the EX271QZ for maximum refresh in competitive titles. The EX271UZ also adds the KVM switch and 90W USB-C, which the EX271QZ does not carry.
Will it drive a PS5 or Xbox Series X at full rate?
Yes. Both HDMI ports are HDMI 2.1 and the MOBIUZ console set covers Auto Low Latency Mode, Variable Refresh Rate, Consumer Electronics Control and eARC. A remote control is included.
Can one keyboard and mouse control two computers on it?
Yes, through the built-in KVM switch. Plug the peripherals into the monitor's downstream USB ports, connect one machine over USB-C and the other over the USB Type-C upstream port, then switch inputs.
Does it come with a Singapore warranty and a GST invoice?
Yes. BenQ Singapore carries a 3 year local warranty on this monitor, and every unit sold by SourceIT is supplied with a GST invoice.
