Product Note
The 270Hz refresh rate is an overclocked maximum; the available refresh rate depends on the connected hardware, interface, and display settings. USB-C supports DisplayPort Alt Mode and up to 15W power delivery, which is insufficient to replace a high-wattage laptop charger. The monitor has no built-in speakers. Confirm the regional SKU, included accessories, warranty, and local availability with the seller before ordering.
