28.2″ 3:2 coding monitor

The BenQ RD280UA is a 28.2-inch IPS display with a 3840 x 2560 resolution and a 3:2 aspect ratio. Its Fine-Coated anti-glare panel and dedicated coding modes are built for developers who spend long hours reading and writing code. A 60 Hz refresh rate and 5 ms response time suit typical desktop work.

Sustained load with 90 W USB-C power

The monitor delivers up to 90 W of USB-C Power Delivery while simultaneously handling video and data, so a connected laptop stays charged during full-day sessions. Typical power draw is 34 W and peaks at 205 W when the USB hub and HDR backlight are both under heavy use. Brightness Intelligence Gen2 and Night Hours Protection automatically adjust luminance to reduce eye strain over extended periods.

Check host port and desk mounting before ordering

Your computer must provide a USB-C port with DisplayPort Alt Mode and Power Delivery to use the single-cable dock, 90 W charging and MST daisy-chain features. The included Ergo Arm stand offers tilt from -5° to 30°, swivel and height adjustment, and the cabinet also supports 100 x 100 mm VESA mounting if you prefer a monitor arm. Verify cable reach for the HDMI 2.0 and DisplayPort 1.4 inputs if you plan to connect multiple sources.

Questions about this item

How much power does the monitor draw when it runs all day at typical brightness?

Typical power consumption is listed at 34 W, rising to a maximum of 205 W when the 90 W USB-C port is fully loaded, and dropping below 0.5 W in sleep mode.

Which video cable must I already have to get 3840×2560 at 60 Hz?

You need either an HDMI 2.0 cable, a DisplayPort 1.4 cable, or a USB-C cable that supports DisplayPort Alt Mode; all three ports can drive the native resolution at 60 Hz.

Will my older laptop with only an HDMI 1.4 port drive the 3840×2560 panel at 60 Hz?

HDMI 1.4 is limited to 4K at 30 Hz, so the monitor would run at a lower refresh rate; use the DisplayPort 1.4 or USB-C input instead for full 60 Hz operation.
