Zeskit's Zinc Alloy HDMI Coupler is for connecting two HDMI cables to give you freedom in having best length of connection for different scenarios.
To ensure high quality signal transmission, we use fully zinc alloy housing, gold plated connectors and PCB for wiring. All these make this Zeskit HDMI adapter stands out among other cheaply made adapters. This simple, little kit is great helper for you who needs cable management and who pursuits high image quality.
Important Usage Instruction
Though the signal loss is low, there's still some due to two connection nodes on this adapter.
General connection quality also depends on the quality of the connected HDMI cables.
With two high quality HDMI cables (e.g Zeskit Cinema Plus series), the total length should not longer than 20ft for 4K video and no longer than 30ft for 1080P video.
Connecting 2 long HDMI cables (e.g 15ft each) will cause significant signal loss (in other words, resolution will downgrade much) because a long HDMI cable is usually designed to achieve certain capability with its own length only. Doubling the designed length will weaken its capability much.
