Dual 4K outputs with distinct operating modes
The VDWall A63 handles mixed UHD, HD and SD sources and outputs through two HDMI 2.0 ports. Its operating modes support different combinations of image composition, live switching and screen splicing; choose the mode that matches the installation.
- Multi-window: up to four windows and six images, using two 4K windows and two 2K windows with PIP/POP.
- Switching: one program output and one preview output, with three windows available for program and preview composition.
- Mosaic: the two outputs can form an 8K × 2K layout. Each output supports dual-image display, for four independent images in this mode.
Image cropping, scaling, positioning and layer order support irregular layouts. The outputs can also show the same image for redundancy. Genlock supports synchronized multi-unit splicing.
