Product Note
The maximum 380Hz refresh rate is an overclocked specification. Actual operation depends on the graphics hardware, connection, supported display mode, and configuration. USB-C provides DisplayPort Alt Mode and 7.5W power delivery; it should not be treated as a high-power laptop charging solution. The monitor does not include built-in speakers. Verify regional model specifications, bundled accessories, warranty, and availability before purchase.
