How to use

Ensure the DisplayPort output on your computer supports passive adapter connections to HDMI. Connect the DisplayPort male end to the computer or docking station and plug the HDMI-A male end into the display device. Select the appropriate input on the monitor or TV and configure display settings on your computer if needed (resolution, scaling, or audio output). For best results power on source and display devices before establishing the connection.

Recommendations

Use the cable within recommended bend radius and avoid crushing or tight kinks. If you experience no signal, check source device compatibility with DisplayPort-to-HDMI passive adapters and verify the display input selection. For long-term installations near other power cords, maintain separation to minimise potential interference.
