Calling a 23.8-inch monitor portable stretches the word, but this one ships with a carrying handle, a C-clamp arm and a hook for cubicle partitions, which tells you who it is for: hot-deskers and contractors who need a full-size second screen wherever they land that week. The panel is plain 1080p office glass at 250 nits. Everything interesting is in the mounting hardware and the 60 W USB-C connection.

Features

23.8-inch 1080p panel with a carrying handle built into the stand
C-clamp arm and partition hook included in the box
USB-C with 60 W power delivery back to the laptop
Full height, swivel and pivot adjustment
Two 1 W speakers and a headphone jack

What it does well

Full-size screen area with a single USB-C cable doing video, data and 60 W of charging
The clamp arm and partition hook mean it attaches to desks and cubicle walls that have no room for a base
Height, swivel and pivot adjustment, which almost no other travel-oriented screen offers
Adaptive-Sync at 75 Hz smooths scrolling and video playback
Standard 100 mm VESA pattern for any arm you already own

What it gives up

1080p across 23.8 inches is 93 pixels per inch — visibly coarse next to any modern laptop panel
250 nits is dim for a screen this size in a bright room
At 10.7 pounds with the mounting hardware it is luggage rather than a bag accessory
HDMI is 1.4, which ASUS's own signal table runs to the panel's full 75 Hz and no further — there is no headroom above this panel at all
The mounting hardware is what the price buys; the panel itself is the same class as desk monitors costing half as much
