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.
