27-inch 4K OLEDs like the EX271UZ are rare,, so I included three 32-inch models in the comparison group. They include Asus’ XG32UCWMG, Dough’s Spectrum Black, and HP’s Omen 32 OLED. At 27 inches are the BenQ, Asus’ PG27UCDM, and Alienware’s AW2725Q. All of them run at 240 Hz.
Pixel Response and Input Lag
Panel response and smoothness are identical for all six monitors. 240 Hz here means 4ms to draw a full white field, and motion patterns run with no visible blur. The EX271UZ includes black frame insertion, which exacts a 40% brightness penalty but eliminates blur at lower frame rates. If you can’t reach 180 fps, it is a good choice.
In the lag test, the EX271UZ comes close to the Asus, scoring 18ms, matching three others. These are all fast monitors, and unless you are a Palpatine or Skywalker, you won’t perceive a difference between them. The BenQ holds its own with the quickest OLEDs available.
Test Takeaway: The EX271UZ showed exemplary video processing and smooth motion in all tests and games. It’s super quick, with instant control response and no hint of motion blur at frame rates over 180 fps. Lower speeds can be smoothed out with the available blur reduction, something not all OLEDs have. Though this is BenQ’s first OLED gaming monitor, it’s on par with the best displays I’ve reviewed.
Viewing Angles
The EX271UZ has nearly perfect off-axis imagery, but you can just see a hint of green in the 45-degree view. That’s an artifact common to Quantum Dot screens since they polarize light more aggressively than non-QD panels. There is no change in brightness or gamma. The top view is solidly bright, with a slight red tint and a minor gamma reduction.
Screen Uniformity

The EX271UZ is on par with other OLEDs in my uniformity test, where it scores 6.90%, well below the visible threshold. You won’t see any glow or hotspots in the 10% field pattern I measured. This is typical OLED performance, which is to say excellent.
