ASUS ROG Strix XG34WCDMTG 34" 240Hz OLED gaming monitor

34" UWQHD QD-OLED for gamers and streamers

The ASUS ROG Strix XG34WCDMTG combines a 34-inch curved QD-OLED panel with a 3440 x 1440 resolution and a 240Hz refresh rate. It targets players who want ultra-responsive motion and creators who value the 21:9 aspect ratio for timeline work. Built-in Android 14 Google TV and WiFi 6 add standalone streaming and cloud gaming without a PC connected.

Upgrade from standard 144Hz ultrawides

Moving to this monitor is worth it when you need the 0.03 ms response time and 1,500,000:1 contrast that only OLED delivers. The jump pays off in fast-paced titles where motion clarity matters and in dark scenes where true blacks reveal detail. FreeSync Premium Pro and G-Sync Compatible support keep variable refresh smooth across both GPU brands.

99% DCI-P3 and 1000 cd/m² peak brightness for HDR

The panel covers 99% of the DCI-P3 gamut with 1.073 billion colours, making it comfortable for colour-grading and HDR content at the VESA DisplayHDR 400 True Black level. Typical brightness sits at 250 cd/m², so sustained full-screen white in SDR workflows stays modest. The 90W USB-C power delivery runs a thin-and-light laptop, but heavier workstations will need their own charger.
