Overview
A 165 Hz refresh rate at 4K gives the BenQ EX271U its purpose: it is a 27-inch IPS gaming monitor combining 3840 x 2160 resolution, 163 PPI and FreeSync Premium. The sheet lists 1 ms GtG, 95% DCI-P3 and 10-bit colour, covering detail, motion and colour. USB-C provides 65 W power with DisplayPort Alt Mode, and the stand includes 100 mm height adjustment plus ±15° swivel. HDR is far less convincing. Typical and peak brightness are both 400 cd/m², leaving zero stated headroom behind DisplayHDR 400, while 1200:1 contrast remains ordinary for IPS. No speakers are included, pivot is effectively absent at ±0°, and the port line is truncated before all video inputs can be read. Buy it if 4K sharpness, 165 Hz gaming and USB-C need to coexist; skip it if meaningful HDR, built-in audio or fully documented connectivity is more important.

HDR & Brightness Reality
The EX271U carries DisplayHDR 400, but the published brightness figures give the badge no room to work. Typical brightness is 400 cd/m² and peak brightness is also 400 cd/m², so there is zero stated reserve for highlights. The 1200:1 IPS contrast is slightly above a basic 1000:1 claim but does not provide OLED-like blacks. HDR10 input is supported; the specification describes compatibility, not a convincing high-dynamic-range display.

Frequently Asked Questions
01 What level of graphics hardware makes sense for the EX271U? +
A high-end GPU is advisable for native 3840 x 2160 at frame rates approaching 165 Hz. Lower settings or resolution scaling may be needed in demanding games.
02 Why does identical 400 cd/m² typical and peak brightness matter? +
It means the sheet shows no extra output for HDR highlights. DisplayHDR 400 therefore confirms a tier, but not visible brightness expansion beyond normal operation.
03 How useful is 163 PPI outside gaming? +
It gives very sharp text, detailed images and a dense desktop workspace. Some users will prefer operating-system scaling for comfortable interface size.
04 What is missing from the EX271U stand? +
It has 100 mm height adjustment, ±15° swivel and -5° to +15° tilt, but the published ±0° pivot means no portrait rotation.
05 Why can’t the full input selection be listed confidently? +
The supplied Ports line cuts off after USB entries. HDMI and DisplayPort quantities are therefore not readable and should not be inferred.
