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.

Questions about this item
Does the 1800R curved stand allow VESA wall mounting if I remove it?
Yes, the stand detaches and the monitor has a standard VESA mount pattern for wall or arm installation.
What is the correct order to connect a laptop with the single USB-C cable for 90W charging and video?
Plug the USB-C cable into the monitor first, then into the laptop; this ensures the DP Alt Mode handshake and 90W power delivery activate together.
How do I clean the QD-OLED panel without damaging the anti-reflective coating?
Use a dry microfibre cloth only; avoid liquids, sprays, or pressure on the 0.03 ms response-time surface.
