27-inch OLED gaming monitor

The Acer Predator X27U F5bmiippruzx is a 27-inch OLED display built for competitive gaming. It delivers a 2560 x 1440 resolution at a 500Hz refresh rate with a 0.03 ms response time. The panel covers 99% of the DCI-P3 colour space and reaches 1000 cd/m2 brightness with a 1,500,000:1 contrast ratio.

FreeSync Premium Pro and ergonomic stand

AMD FreeSync Premium Pro provides variable refresh rate support for tear-free gameplay across the full 500Hz range. The included stand offers height adjustment up to 120mm, swivel of +/- 20°, pivot of +/- 90°, and tilt from -5° to 20°. Connectivity includes two DisplayPort 1.4 ports, two HDMI 2.1 ports, and one USB Type-C port with DisplayPort Alternate Mode.

High-speed 1440p performance envelope

This monitor comfortably handles high-frame-rate 1440p gaming where graphics cards can sustain hundreds of frames per second. The 0.03 ms pixel response keeps motion clear at the 500Hz ceiling. It runs out of headroom for users who need 4K resolution, wider colour volume beyond DCI-P3 99%, or HDR performance beyond the 1000 cd/m2 peak.

Questions about this item

Will the OLED panel on the X27U F5bmiippruzx need replacement because of burn-in?

The 0.03 ms response time and 1000 cd/m2 peak brightness reduce static-image retention, but OLED technology can still show permanent burn-in after many thousands of hours with fixed UI elements.

What limit appears first during a long 500 Hz session on the 2560 x 1440 panel?

Sustained 500 Hz output at 1440p is capped by the DisplayPort 1.4 and HDMI 2.1 bandwidth, so the interface limit is reached before the panel itself throttles.

How loud and hot does the X27U F5bmiippruzx get when it runs all day at 500 Hz?

The monitor has no active cooling fans, so it stays silent; surface temperature rises modestly due to the OLED panel and 1000 cd/m2 brightness but stays within normal operating range.
