1

Unbox and inspect the cable

Remove the 9-Pin Null Modem Cross 1.8M from its packaging. Check both connectors for any bent pins or damage before use.

2

Identify your ports

Locate the matching ports on both your source device (laptop, PC, console, player) and your display (monitor, TV, projector).

3

Connect the cable

Plug one end of the 9-Pin Null Modem Cross 1.8M into the source device and the other end into your display. Connectors are keyed — do not force them.

4

Power on your devices

Turn on your source device first, then your display. Most devices auto-detect the connection.

5

Select the correct input

On your display or TV, use the remote or on-screen menu to select the correct input source (HDMI 1, HDMI 2, DP, VGA, etc.).

6

Adjust resolution settings if needed

On Windows: right-click desktop → Display Settings → set to recommended resolution. On Mac: System Preferences → Displays → set resolution.
