Overview

It offers UWQHD resolution, 109 ppi pixel density, 350 nits typical brightness, 2000:1 static contrast and 100% sRGB and 98% DCI-P3 coverage. The panel refreshes at 56–76 Hz and quotes 5 ms response. Inputs include 2× HDMI 2.1, 1× DisplayPort 1.4, USB-C 90 W and 5× USB-A. The stand offers 150 mm of height adjustment and swivel. 2 × 5 W speakers are built in, and it weighs 11.44 kg with the stand.
