4.2. 180-Degree Rotation Function

The 180-degree rotation function is particularly useful for minimizing noticeable gaps between displays in a 2x2 configuration, especially when using TVs with thicker bottom bezels. This feature allows for a more seamless and complete image.

Operation Steps:

1. Physical Setup: For a 2x2 setup, physically install the top two TVs upside down.
2. Remote Control Sequence:
   • Press the "180°" key on the IR remote controller.
   • After a 1-second interval, press the numeric key "1".
   • After another 1-second interval, press the "OK" button to confirm.

Important Notes:

• All output ports support 180-degree rotation, which also aids in flexible cable management.
• The device itself does not support 90-degree rotation. For portrait modes, you may need to configure your PC's display settings to rotate the image by 90 degrees.
