Recommendations

For best results, calibrate colour settings when performing colour-critical work and set the monitor to its native resolution (3440 x 1440) to ensure optimal sharpness. Maintain a viewing distance appropriate for a 34" UltraWide display so that the curved panel remains within your comfortable field of view. Ensure adequate ventilation around the monitor and route cables to avoid strain on ports.
