Use the on-screen display controls to set brightness, color temperature, and input selection according to your environment and source device. For best image quality, allow the monitor to warm up for a short period after powering on and use native resolution settings on your operating system.

Recommendations

For color-sensitive work, calibrate the display with a hardware colorimeter and select a color profile matching your workflow. Keep the firmware and graphics drivers up to date, position the screen to avoid direct sunlight on the panel, and use the built-in speakers for basic audio but consider external speakers or headphones for higher fidelity.
