Overview
A 4K panel, 10 W audio and 65 W USB-C make the BenQ EW2790U a 27-inch IPS monitor for mixed home use rather than high-refresh gaming. Its 3840 x 2160 resolution produces 163 PPI, while 99% sRGB, 95% DCI-P3 and 10-bit colour give it broad coverage. The stand offers 110 mm height adjustment and ±20° swivel, and USB-C combines DisplayPort Alt Mode, 5 Gbps data and laptop power. Motion is limited to 60 Hz with a 5 ms GtG response. HDR10 and DisplayHDR 400 are listed, but 350 cd/m² typical rises to only 400 cd/m² peak, leaving little highlight headroom. The port line is truncated before HDMI and DisplayPort details can be confirmed. Buy it if sharp 4K desktop use, strong built-in audio and one-cable laptop connectivity matter; skip it if fast gaming, precise HDR or a fully documented input list is required.

HDR & Brightness Reality
DisplayHDR 400 is a weak part of the EW2790U specification. Typical brightness is 350 cd/m² and peak brightness is 400 cd/m², so highlights gain only 50 cd/m² over normal output. The 1000:1 IPS contrast also limits dark-scene depth, and no local-dimming information is published. HDR10 content can be accepted, but the hardware figures point to basic compatibility rather than a wide luminance range. The monitor’s stronger case is 4K clarity and colour coverage.

Frequently Asked Questions
01 How sharp is 4K on the 27-inch EW2790U? +
The panel reaches 163 PPI, so text and fine image detail are much denser than on 27-inch QHD or Full HD screens. Interface scaling may be useful for comfortable text size.
02 What can the EW2790U’s 65 W USB-C replace on a desk? +
It can carry display data, USB traffic and up to 65 W power through one cable. Laptops that require more than 65 W may still discharge under heavy load.
03 Why are the built-in speakers more relevant than usual here? +
The sheet lists two 5 W speakers for 10 W total output, which is higher than many monitor speaker systems. Sound quality and bass extension are not published.
04 What prevents DisplayHDR 400 from adding much impact? +
The 400 cd/m² peak is only 50 cd/m² above the 350 cd/m² typical level. There is also no local-dimming specification to improve local contrast.
05 Which connectors remain uncertain from the supplied EW2790U sheet? +
The USB-C and part of the hub are visible, but the Ports line cuts off before complete HDMI and DisplayPort information. Those quantities should not be guessed.
