• Video Wall Modes: 2x2, 1x2, 2x1, 1x3, 3x1, 1x4, 4x1. These modes combine multiple screens to form a single large display.
• Splitter Mode: 1x4. This mode duplicates the input signal across all four outputs.
• Portrait Modes: 1x2, 1x3, 1x4. These modes are available when the PC source is configured for portrait display, allowing for vertical video wall arrangements.

5.2. 180° Rotation Function

In 2x2 Video Wall Mode, each screen's image can be rotated by 180 degrees. This feature is useful for adjusting the border orientation, allowing you to use the thinnest bezels of your displays to minimize the splicing gap. Use the '180° Rotate' button on the IR remote.

5.3. Edge Masking Function

The Edge Masking function prevents image distortion and an unnatural appearance at the seams of your video wall. It works by adding or cutting the output picture edge by 8 pixels. This helps to create a more seamless visual experience across multiple displays. Use the 'EDGE MASK' button on the device or the IR remote.

5.4. Audio Extraction

The controller supports audio extraction from the HDMI input. You can extract 5.1 channel audio via the Toslink output or 2.0 channel audio via the 3.5mm stereo output. Use the '2.1/5.1CH' button on the device or remote to switch between audio modes.
