Two and a half pounds, 2560×1600, 120 Hz and 500 rated nits — and the brightness is the part that matters, because most portables stop near 300 and wash out anywhere near a window.
Best for: A second screen in a bag that is good enough to be the only screen
- HDMI 2.0· full speed
- USB-C (DP Alt Mode)· full speed

ASUS ZenScreen MB249C

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.
Best for: A full-size second screen for a desk you do not keep

ASUS ZenScreen MB16QHG: what it gives up
- It draws power from the host rather than supplying any, and ASUS tells HDMI users to attach the in-box adapter rather than run it off the laptop
- No speakers, only a headphone jack, so sound stays with the laptop
- No VESA mount — a quarter-inch tripod socket is the only fixing point, and the kickstand only tilts
- DisplayHDR 400 over a 1200:1 IPS panel with no dimming zones is an HDR badge rather than HDR
ASUS ZenScreen MB249C: 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
