BenQ EW2790U 27-Inch 4K IPS USB-C Monitor

BenQ EW2790U 27-inch 4K IPS Monitor

The BenQ EW2790U is a 27-inch entertainment monitor built around a 4K UHD IPS panel, integrated treVolo speakers and single-cable USB-C connectivity. It is designed for a desk that has to handle work documents, streamed films, console gaming and light content creation on the same screen,. The panel resolves 3840 x 2160 pixels at a 163 ppi pixel density, so text stays sharp at normal viewing distances and photos and video show fine detail that a Full HD screen cannot reproduce.

Picture quality for work and viewing

The IPS panel holds its colour and contrast across wide 178-degree viewing angles, which matters when the screen is shared or viewed slightly off centre. Native contrast is rated at 1000:1, typical brightness is 350 nits, and response time is 5ms GtG, a balance aimed at mixed use rather than competitive gaming. Colour modes include Rec.709, sRGB, HDR, M-Book, Game and Cinema settings, and the anti-glare coating keeps reflections manageable in a normally lit room.

HDRi and everyday image processing

BenQ HDRi processing works with HDR10 content and the DisplayHDR 400 brightness range to map tone more intelligently than a simple brightness lift. Cinema HDRi and Game HDRi presets adapt that processing to films and games respectively. Brightness Intelligence Gen2 uses an ambient light sensor to adjust brightness and colour temperature as room lighting changes through the day, so the picture stays consistent from morning work to evening viewing without repeated manual adjustment.

Sound without extra speakers

Two built-in 5W treVolo speakers handle dialogue, music and casual gaming audio directly from the monitor. Six audio modes, covering User, Dialogue or Vocal, Live or Pop, Cinema, Game and Studio Monitor, let the tuning follow the content, and a headphone jack is provided for private listening. For many desks this removes the need for separate desktop speakers altogether, keeping the setup compact while still giving films and video calls clear, present sound.

Connections, ergonomics and eye care

A single USB-C cable can carry the picture, data and up to 65W of charging power to a compatible laptop. Three HDMI 2.0 ports cover additional sources such as a console or media player, and the hub adds three USB-A and one USB-C downstream ports for peripherals. The stand provides 110mm of height adjustment along with tilt, swivel and pivot. Low Blue Light Plus, flicker-free operation and the Brightness Intelligence sensor form the BenQ Eye-Care suite for longer sessions, and the cabinet is made with 85% post-consumer recycled plastic.

Taken together, the EW2790U suits a home office or living-space desk where one 4K screen must serve documents, streaming, console play and occasional colour work, with sound and laptop charging handled by the monitor itself.
