Key strengths
USB-C with DisplayPort Alt Mode accepts video at up to 180 Hz from a source whose USB-C port supports DP Alt Mode, alongside DisplayPort 1.4 and HDMI 2.0.
ELMB Sync is listed, so blur reduction can run with variable refresh; FreeSync, G-SYNC Compatible and VESA AdaptiveSync Display 180Hz are also listed.
The stand provides 120 mm height travel, ±45° swivel and ±90° pivot, with a 100 × 100 mm VESA pattern and a tripod socket.
Before you buy
USB-C power delivery is listed at 7.5 W; ASUS’s product page describes using it to charge a phone held on the stand.
HDMI is limited to 144 Hz and there are no built-in speakers.
ASUS’s tables and user guide list no downstream USB ports, although the product page says the USB-C port can serve as a USB hub. On-mode power appears as “<23.1W*” in the ASUS tables and as 23.1 W in the user guide, with no measurement basis stated.
Every specification. With its source.
