Predator X27U 27" QD-OLED

The Acer Predator X27U is a 27-inch QD-OLED gaming monitor built for competitive players who need speed and colour accuracy.

280Hz refresh with 0.03ms response

A 280Hz refresh rate shortens frame intervals for smoother motion in fast-paced titles. The 0.03ms pixel response time keeps transitions clean and reduces ghosting. Brightness reaches 250 nits typically and peaks at 1000 nits in small HDR highlights, while the 100,000,000:1 contrast ratio delivers deep blacks.

VESA DisplayHDR True Black 400 certification

The display meets VESA DisplayHDR True Black 400 requirements, confirming its ability to render true black levels and controlled highlight performance. This certification is the single specification that determines whether the monitor satisfies HDR quality expectations for gaming and content creation.

Questions about this item

Will the 27-inch 2560 x 1440 QD-OLED panel fit a standard 100 mm VESA arm?

The monitor uses a 100 x 100 mm VESA pattern, so any mount or arm with that spacing will attach directly.

Does the 280 Hz refresh rate and 0.03 ms response time require a specific cable or GPU output?

Use a DisplayPort 1.4 or HDMI 2.1 connection; both carry the full 280 Hz at 1440p with the panel's native 0.03 ms pixel response.

How bright does the screen get in HDR and what does the True Black 400 rating mean?

Typical brightness is 250 nits, peaking at 1000 nits on a 3 % window; VESA DisplayHDR True Black 400 certifies deep black levels and 99 % DCI-P3 colour.
