Case Study: Delivering Flawless 5K@240Hz Performance with ConnectPRO KVM and Fiber Extension Technology

Case Study: Delivering Flawless 5K@240Hz Performance with ConnectPRO KVM and Fiber Extension Technology

The Challenge: Ultra-High Refresh Rate, Multi-System Control—Without Compromise

Modern professional environments demand extreme performance. In this project, a client needed to integrate a setup capable of delivering ultra-high refresh rate video, seamless Mac and Windows system switching, and long-distance signal transmission over fiber—all without sacrificing video or USB performance.

The system had to support:

  • 5K resolution up to 240Hz

  • Dual monitors operation

  • MacBook Pro M1 and Windows 11 PC

  • Fiber-based DisplayPort extension

  • USB 3.0 support for peripheral devices

  • Broadcast-grade audio equipment

Any instability—blank screens, flicker, or signal degradation—would be unacceptable in a mission-critical environment.


The Solution: ConnectPRO UDP2-12AP with Certified Fiber Extension

At the core of the system was the ConnectPRO UDP2-12AP DisplayPort KVM switch, selected for its ability to handle high bandwidth requirements and advanced USB routing. The system architecture included:

  • KVM Switch: ConnectPRO UDP2-12AP

  • Docking Station: CalDigit TS4 Thunderbolt 4

  • Fiber Extension: 2 × DVIGear DVI-7380 DisplayPort Extenders

  • Systems:

    • MacBook Pro M1

    • Windows 11 PC

  • Displays:

    • LG 49GR850C-B (5120×1440 @ 240Hz, DP1.4 DSC)

    • Dell 4K (3840×2160 @ 60Hz)

  • Cabling:

    • VESA Certified DP2.1 D-40 cables

    • CAC-1557 USB-C to DP cables

    • USB 3.0 and USB-C uplink cables

  • Professional Audio: USB DAC, Shure SM7B microphone, and IEMS system

This configuration was designed to ensure fully transparent switching, zero latency perception, and uncompromised image fidelity—even at high refresh rates.


The Results: 100% Stability at 5K 240Hz

Using ConnectPRO-certified signal path, the system achieved perfect performance across all tests:

  • ✅ Smooth, stable 5K at 240Hz output

  • ✅ Reliable 4K at 60Hz secondary display

  • ✅ Flawless USB 3.0 device performance

  • ✅ Broadcast-grade audio integration with zero interference

  • ✅ Seamless switching between Mac and Windows systems

Final Test Conclusion:
All tests with the default certified hardware profile passed without any issues.

This real-world validation confirms that the ConnectPRO UDP2-12AP is fully capable of supporting ultra-high refresh rate, dual-platform, fiber-extended workflows—a requirement typically seen in production studios, high-end gaming setups, esports, and advanced control rooms.


The Proof Point: When Cabling Becomes the Bottleneck

To demonstrate real-world sensitivity, the team introduced a secondary configuration using:

  • A 25-ft passive DisplayPort cable

  • A third-party Ugreen USB-C to DP adapter

This configuration immediately resulted in:

  • ❌ Blank screens

  • ❌ Poor video quality

  • ❌ Intermittent instability

The test clearly confirmed that non-certified cabling—not the KVM or fiber extenders—was the true source of failure. Once the system reverted to ConnectPRO-recommended cabling, full performance was restored.


Business Impact

This successful deployment delivers powerful value for integrators, IT managers, and enterprise buyers:

  • Proven 5K@240Hz KVM performance in the real world

  • Validated long-distance fiber extension

  • Full Mac + Windows interoperability

  • Guaranteed USB 3.0 and audio reliability

  • Reduced risk through certified cabling profiles

  • Elimination of signal instability in mission-critical environments


Conclusion: Built for Extreme Performance

This project confirms that ConnectPRO’s UDP2-12AP KVM switch, when paired with certified DP2.1 cabling and professional-grade fiber extenders, delivers rock-solid performance at the highest refresh rates available today.

For environments that demand:

  • Ultra-high refresh rates

  • Zero signal compromise

  • Long-distance transmission

  • Multi-system control

ConnectPRO delivers with absolute confidence.
