Best thing: OLED contrast at a mid-range level
Honest catch: 300 nits typical — dimmer than many laptop screens
If you want the deep blacks and rich colour of OLED without paying for 4K, this is the sweet spot: light, well equipped and accurate, with a P3 preset for Macs. The compromises are a modest 300-nit rating, a glossy screen, a 1920 × 1200 resolution that is less crisp than 4K on a Mac, and no speakers.
OLED gives true blacks and very high contrast, so films and dark-mode apps look far better than on a typical IPS portable.
95% DCI-P3 with Delta E < 2 means colour that is both rich and accurate — good for checking photos and designs on the go.
The 16:10 shape shows more lines of text than a 16:9 screen of the same width, matching most modern laptops.
A built-in kickstand plus a tripod socket — no folding case to balance on a hotel desk.
On a Mac, ASUS’s “M Model” P3 colour preset aligns the colours with macOS (after installing the ASUS ICC profile).
Plug the monitor into power and it can pass up to 65 W on to your laptop through the same USB-C cable.

Yes, if the laptop’s USB-C port supports DisplayPort Alt Mode (Thunderbolt and USB4 ports do) — ASUS asks you to check this first. If it does not, use the mini HDMI port for video and power the monitor through USB-C with the included adapter.
For colour, yes: ASUS offers an “M Model” P3 preset for Macs once you install its ICC profile, and the 16:10 shape matches MacBook screens. For sharpness, 1920 × 1200 on 16 inches looks softer on macOS than a 4K portable.
Yes, with the monitor plugged into a USB-C power bank or adapter it passes power on to the laptop, up to 65 W. ASUS notes the adapter must supply up to 90 W to reach that maximum.
