23.8-inch 144 Hz IPS monitor for daily work

The BenQ GW2490C is a flat-panel display built around a 23.8-inch IPS screen running at 1920 x 1080 resolution and a 144 Hz refresh rate. It covers 99 percent of the sRGB gamut and delivers 250 cd/m2 brightness with a 1,500:1 contrast ratio. The 5 ms grey-to-grey response time and 178-degree viewing angles suit general office tasks, video playback and casual gaming alike.

Single DisplayPort 1.2 and HDMI 1.4 plus USB-C

Video enters through one DisplayPort 1.2 and one HDMI 1.4 connection, while a USB Type-C port handles data and peripheral links. The built-in 90 to 264 V AC supply removes the need for an external brick, and the stand provides -5 to 20 degrees of tilt adjustment. VESA 100 x 100 mm mounting points allow wall or arm installation when desk space is tight.

1080p at high refresh with basic colour needs met

At 1920 x 1080 the panel drives smoothly at 144 Hz from most modern integrated or discrete graphics without demanding heavy GPU resources. The 99 percent sRGB coverage handles everyday content creation and media consumption, while the 250 cd/m2 peak brightness is adequate for normal indoor lighting. Users requiring wider gamuts, higher resolution or HDR brightness will need a different class of display.

Questions about this item

How long before the 5 ms grey-to-grey response time shows motion blur in fast scenes?

The panel is rated at 5 ms GtG so blur only becomes noticeable when pixel transitions exceed that speed, which typical 144 Hz gaming does not reach.

What are the noise heat and power figures when the monitor runs all day at 144 Hz?

Built-in 2 W speakers are the only moving parts so acoustic noise is near zero; power draw is 20 W in on mode and below 0.5 W in power saving.

Which cable must I already own to get 144 Hz at 1920 x 1080?

A DisplayPort 1.2 cable is required; the HDMI 1.4 port cannot deliver 144 Hz at this resolution.
