For devices that support USB Type-C downstream, connect the USB Type-C port to enable peripheral access through the built-in USB hub. Connect speakers or headphones to the 3.5 mm audio output if required. Adjust brightness, contrast and color settings through the on-screen display menu to match ambient lighting and task requirements.

Recommendations

For comfortable viewing, position the top of the screen at or slightly below eye level and maintain an arm's length distance. Use medium to high brightness in well-lit rooms and lower brightness in dim environments to reduce eye strain. When color-critical work is required, perform calibration with suitable tools and allow the monitor to warm up for accurate color rendering.
