Product Note
The XG34WCDMTG is a 3440 × 1440 ultrawide QD-OLED monitor, not a 4K UHD display. Achieving 240Hz depends on the connection, graphics hardware, resolution, and display settings. USB-C power delivery is rated at up to 90W; confirm laptop compatibility and power requirements before relying on single-cable operation. Smart-TV features and wireless services may vary by region, network, and software availability. OLED care practices are recommended to reduce the risk of image retention over time. Verify regional warranty coverage, included accessories, and local service availability with the seller.
