34″ BenQ PD3420Q – Specs & Features
The BenQ PD3420Q is a 34-inch IPS monitor built around single-cable laptop setups, with 65 W of USB-C power delivery.
Overview
The BenQ PD3420Q is a 34-inch IPS monitor built around single-cable laptop setups, with 65 W of USB-C power delivery. It offers UWQHD resolution, 109 ppi pixel density, 350 nits typical brightness (400 nits peak), 1000:1 static contrast and 100% sRGB and 98% DCI-P3 coverage. The panel refreshes at 60 Hz and quotes 5 ms GtG response. Inputs include 2× HDMI 2.0, 1× DisplayPort 1.4 and USB-C 65 W. The stand offers 150 mm of height adjustment and swivel. 2 × 2.5 W speakers are built in, and it weighs 9.3 kg with the stand. It suits laptop users who want one-cable docking at the desk. The main trade-off: capped at 60 Hz, so fast games will not feel as smooth.
