VDWALL A63 4K Multi-Window Processor
The VDWALL A63 handles mixed SD, HD and UHD sources for small-pitch LED displays. It provides separate operating modes for layered picture composition, previewing the next scene and combining outputs across a wider screen.
Choose the Display Mode for Your Installation
- Multi-window display: up to four windows and six pictures, comprising two 4K windows and two 2K windows. The 2K windows support PIP/POP. Adjust cropping, size, position, overlap and picture borders.
- Switching mode: use one HDMI output for program and the other for preview. Three program windows and three preview windows support simultaneous seamless or fade transitions.
- Mosaic mode: combine the two outputs for an 8K × 2K image using two 4K controllers. Each output supports two pictures, for four independent pictures across the pair.
- Monitoring or backup: the outputs can carry the same image for synchronized monitoring or output-image backup.
Source Handling and Control
The listed inputs include five HDMI 2.0, three DP 1.2, two DVI-compatible, two SDI and two CVBS connections. Image processing includes Faroudja de-interlacing and enhancement, independent RGB adjustment with 256 levels, and nine saved multi-window display modes. Control is available from the front panel or a computer through RS232, USB or LAN.
Genlock supports synchronized cascading. The listed four-unit configuration extends input to 8K4K at 60 Hz and output to 16K4K at 60 Hz; these are multi-device capabilities, not single-unit output specifications.
Technical Specifications
DisplayPort clarification: The input inventory lists DP 1.2, while the original format table also contains a DP 1.4 / 7680 × 2160 entry. The values are retained below for reference, but DP 1.4 capability for the supplied A63 must be confirmed before planning an 8K input.

Frequently Asked Questions
How many video inputs does the A63 have?
The product specification lists 14 inputs: five HDMI 2.0, three DisplayPort, two DVI-compatible, two SDI and two CVBS connections.
How many windows can the A63 show?
Multi-window mode supports four windows and six pictures. Switching mode uses three program windows and three preview windows; mosaic mode provides two pictures per HDMI output.
Can I preview a scene before sending it to the LED wall?
Yes. In switching mode, the two HDMI outputs operate as program and preview, with seamless or fade transitions.
Can one A63 drive an 8K-wide mosaic?
The listed mosaic arrangement combines its two HDMI 2.0 outputs with two 4K controllers for an 8K × 2K image. This is distinct from the resolution of one HDMI output.
Does the A63 support synchronized cascading?
Yes. Genlock provides synchronization between units. Match the number of processors, source arrangement and screen geometry to the documented cascading configuration.
