30,000 lumens, 4K UHD, 3-chip DLP laser phosphor large venue projector


30,000 lumens, 4K UHD, 3-chip DLP laser phosphor large venue projector

  • Stunning experiences thanks to high-brightness images 
  • Savings on installation and shipping time 
  • Laser phosphor light source for reduced costs 
  • 24/7 operation

The UDX range delivers stunning experiences and savings on installation and shipping time, reducing costs significantly. The most compact, high-brightness laser projectors with integrated cooling on the market bring reliable and razor-sharp 4K images to every type of event and venue.

The UDX-4K28 features 4K UHD and 30,000 lumens light output to ensure flawless shows with accurate colors. The Constant Light Output (CLO) also provides constant brightness and color over time. Users enjoy the widest color spectrum in the industry that matches the renowned Xenon quality and outperforms the Rec. 709 color space - without compromising on brightness.

Cut costs with laser projection

The laser phosphor light source reduces lamp-related costs, maintenance as well as image flicker. The result is a long lifetime and high reliability for minimal downtime, while compact and rugged design reduces shipping and labor costs. The modular components limit servicing time. You can also reuse your TLD+ lenses.

Faster processing for sharper images

The Barco Pulse 4K electronics offer an intuitive interface and flexible, user-friendly, embedded control software. Its Single Step Processing (SSP) allows for sharper images and less latency.
