UD100 Series: 4K Processor for Projector Edge Blending on Flat, Curved, and 360° Screens

What it addresses

  • This 4K processor handles seamless multi-projector alignment, curved and 360° warping, overlap edge blending, color matching, and flexible multi-window layouts. By using a hardware-based 4K processor, installers can avoid PC complexity while maintaining stable performance and fine image control.

Quick Answers to Common Questions

  • How do I blend 2–4 projectors in 4K?  Use the UD102 (2 projectors), UD103 (3 projectors), or UD104 (4 projectors). Each model is a scalable 4K processor built for projector edge blending.
  • Can it handle curved or corner walls?  Yes. The 4K processor supports advanced warp, Linearity Grid Line Adjustment, and Corner Wall mapping for 90° corners and curved screens.
  • What about color and black level?  Each 4K processor provides independent R/G/B gamma control in blend regions, per-output color correction, and 9-region black level uplift to compensate for light leakage.
  • Can I display multiple inputs at the same time?  Yes. This 4K processor supports PIP/POP and 3- or 4-way split views per channel. The UD104 4K processor can show up to 16 independent windows.
  • Do I need a PC to run this 4K processor?  No. The 4K processor is controlled via front keypad, IR, USB, WebGUI, or Ethernet, with HDMI loop-through for daisy-chaining.

Real-World Use Cases

  • Flight or driving simulation: Projector edge blending combines three laser projectors into a seamless, low-latency 4K field of view with frame lock and precise geometry control.
  • Planetarium and dome: Projector edge blending supports curved screens using grid alignment and W-shape corner adjustment for accurate starfield projection.
  • 360° immersive events: Projector edge blending with UD104 drives four projectors and up to 16 sources across a continuous 360° display.
  • Museum/video wall: Projector edge blending enables content cropping, rotation, and masking per projector for clean, aligned visuals.
  • Budget projector upgrades: Projector edge blending adds warp and blending to projectors without lens shift or built-in blending.
