Model UHDX Highlights
Designed, packaged and tested in Orlando Florida, USA
Powered by 18G Go! Active Technology
Active electronics do not require external power supplies
Certified to 18Gbbs to support UHD HDMI 4K/60 HDR signals
Earned 18G certification from two independent test labs: ISF & DPL Labs
Power Grip connectors are tight fitting without the death grip of lockingconnectors
Flexible UL CL2 rated cable appropriate for in-wall use
The Tributaries UHDX 18G X-TEND Ultra High Definition HDMI cables were expertly engineered to support 18Gbps for long distance runs. The UHDX is powered by Tributaries' innovative 18G Go! Active Technology. 18G Go! Active Technology compensates for signal attenuation inherent in copper wires. Each data line is received as an attenuated differential pair. Signal conditioning is performed on the positive and negative inputs and the result is equalized using a built-in test feature in the active electronics. In production each cable is tested and equalization values applied specifically for that cable's unique attenuation value resulting in consistently reliable 18Gbps UHD HDMI signal transmission. These cables are directional in nature due to active electronics built into the display-end connector. The X-Tend uses a patented power-harvesting technology that only draws 5mA off the HDMI 5V line which allows the Go! Active Technology to be supported without external power supplies and will not draw down the line voltage to ensure signal integrity. That's why Tributaries guarantees UHDX will provide 18Gbps 4K/60/Deep Color/HDR UHD HDMI signal transmission.
DPL Labs Seal of Approval
Tributaries UHDX models have received DPL Labs 4K Cable Certification. The certification has 2 levels: 10.2Gbps and the coveted 18Gbps level. Tributaries is one of the first cable companies to receive this prestigious 18Gbps certification.
UHD HDMI Cable Design
Tributaries offers the most advanced line of UHD HDMI cables available today. These cables have been custom designed to provide optimal operational 18Gbps performance. Every conductor in each cable length was electronically analyzed for its data rate capability with the result balanced against its gauge and flexibility. To guarantee optimal performance, VEGA, TITAN, X-TEND, PRO and SLIM models have undergone rigorous testing by DPL Labs and have earned the coveted 18Gbps Seal of Approval. DPL labs test every conductor to ensure 4K compatibility with bandwidth certified to 18Gbps enabling HDR. All UHD cables are 18Gbps certified by ISF for Interoperability.
Focus on DDC
When a source and sink are connected the Display Data Channel (DDC) line communicates the EDID information and a HDCP handshake takes place. This handshake is required at start-up and is repeated continuously; if there is an error, the system will stop operation. The EDID data is transmitted via signal pulses. Due to the effect of capacitance, these pulses will degrade when they pass through a cable. The longer the cable, the greater the degradation. A cable with excessive capacitance will slow down the voltage Rise Time for each pulse, effectively degrading the data to the point of error and signal failure. All Tributaries UHD HDMI cables are designed with low capacitance on the DDC line to ensure error-free performance.
Power Grip:
The UHDX HDMI cable has the patented Power-GripTM connector. Multi-locational raised elements provide proper tension top-to-bottom and side-to-side. Tributaries guarantee their connector will not shift in the electronics causing signal drop outs.
