6.3 Image Rotation (180°)
To adjust the orientation of individual screens and minimize bezel gaps, each screen's image can be rotated by 180°. Use the 180° DREHEN button on the IR remote to apply this function.
6.4 Bezel Adjustment (Edge Masking)
The bezel adjustment feature allows you to compensate for the physical bezels of your displays, making the image appear continuous across screens. Press the H-BEZEL or V-BEZEL buttons on the IR remote to add or cut output picture edges in 8-pixel increments. This prevents image deformation and stretching.
