4K source selection and LED screen splicing
The VDWall A65 combines five UHD inputs with three additional HD/SD inputs for LED screen projects. Four synchronized DVI outputs support a 3840 × 2160 screen layout. Input cropping and adjustable output image size and position support irregular screens.
Automatic splicing calculations use the dimensions and position of each screen section. The processor supports seamless and fade transitions, 13 preset display modes, and individual RGB saturation, gray-level and brightness adjustment. A DVI output can provide synchronized monitoring on a 1080p LCD.

Frequently asked questions
How many 4K inputs does the A65 have?
It has five UHD inputs: three HDMI 2.0 and two DP 1.2. The input table lists up to 4096 × 2160 at 60Hz.
Can multiple A65 units be synchronized?
Yes. Genlock cascading is listed. Four A65 units are described for 8K4K at 60Hz or 16K2K at 60Hz pixel-to-pixel applications; review the Genlock guide for configuration.
Does every DVI output carry a complete 4K image?
The four outputs form a synchronized splicing layout. Each output has its own supported timing and custom width/height limits; a full 4K input is distributed across the screen layout.
Can the A65 be used with an irregular screen shape?
Yes. Input cropping and adjustable output size and position are supported. Configure each section according to the actual LED screen dimensions.
