In October 2024, VMX Visual marked a significant milestone in sports venue digitization with the completion of the premium ice hockey stadium project at the iconic KV Arena in Karlovy Vary, Czech Republic. Utilizing our high-definition ZU-251 (P2.5mm) series seamlessly integrated with the proprietary VMX Visual Scoring System, this 126-square-meter display solution delivers an electrified, world-class game day experience for fans and athletes alike.
KV Arena is renowned for hosting elite European ice hockey matches. To meet the rigorous broadcasting standards of modern sports, the venue required a massive visual upgrade capable of displaying real-time live video, instant replays, and dynamic scoring data. VMX Visual installed a state-of-the-art configuration comprising 4 massive LED screens, each measuring 6 meters in width by 2.5 meters in height. Combined into a stunning 126 square meter multi-sided center-hung scoreboard system, the indoor fixed installation ensures a wide 160° horizontal viewing angle, making every seat in the stadium the best seat in the house.
The ZU-251 series stands out for its ultra-slim profile and robust die-cast aluminum frame, making it the perfect choice for high-precision stadium installations:

Implementing a high-end visual matrix inside an active ice hockey stadium requires sophisticated hardware and software synchronization:
- ▸Native VMX Visual Scoring System: This project goes beyond basic video playback. The screens run on the native VMX Visual Scoring software, synchronizing game timers, penalty metrics, shot counts, and multi-player stats with real-time accuracy, allowing the arena referees and operators to manage game-flow effortlessly.
- ▸6,000:1 Exceptional Contrast for Ice Rinks: Due to the stark, reflective nature of white ice surfaces, indoor hockey scoreboards often suffer from washed-out colors. The ZU-251 solves this with a custom matte mask design yielding a 6000:1 high contrast ratio, ensuring text remains needle-sharp and team logos look vivid against any background.
- ▸Ultra-Thin 40mm Space Optimization: Hanging four large screens above the center ice rink demands structural efficiency. The ZU-251's class-leading 40mm thickness and lightweight 11kg die-cast aluminum profile minimize load stress on the roof trusses while maximizing structural safety.
"The integration of VMX Visual’s ZU-251 hardware and their specialized scoring software has elevated KV Arena to a premium entertainment stadium. The fast-paced hockey puck is completely blur-free on the screens thanks to the 3840Hz refresh rate. It's a game-changer for fans and sponsors." — Stadium Technology Manager, Karlovy Vary.

Q: How does the ZU-251 series integrate with the VMX Visual Scoring System for live hockey games?
The ZU-251 is engineered for native hardware compatibility with the VMX Visual Scoring System and NovaStar A5S Plus controllers. This software-hardware integration allows for real-time sports data synchronization with millisecond-level latency. Player stats, penalty timers, and live match scores are rendered instantly, while ultra-fast control protocols ensure seamless switching between live game broadcasts and instant replay loops without frame drops or display glitches.
Q: Why is a 3,840Hz refresh rate necessary for ice hockey arena displays?
Ice hockey is one of the fastest sports in the world, with the puck traveling at speeds over 150 km/h. Professional broadcast cameras and stadium fans filming with smartphones require a high refresh rate to prevent motion blur, flickering, and rolling shutter artifacts. The ZU-251’s 3,840Hz professional refresh rate eliminates all scan lines and ghosting, capturing the high-speed action perfectly for crisp slow-motion replays and live TV broadcasting.
Q: Is 600 nits brightness sufficient for an indoor stadium like KV Arena?
Yes. For indoor sports arenas with professional ice-surface reflection and controlled ambient lighting, 600 nits is the optimal industry sweet spot. Combined with an extraordinary 6,000:1 high contrast ratio and 14-bit grayscale, the display easily cuts through the intense glare of stadium floodlights to deliver deep black levels and vibrant team colors without causing eye strain to the spectators or athletes on the ice.
