Maximum Cable Lengths for Achieving 4K60 4:2:0 with KRT-H
KRT-3-H is a high-speed HDMITM with Ethernet cable retractor that can pass signals
up to 4K@60Hz (4:2:0) resolution when used with Kramer high-quality cables. To
ensure 4K@60Hz (4:2:0) resolution when using KRT-3-H, we tested a selection of
Kramer HDMI cables to discover the maximum length for each cable model. Please
see the recommended list below.

The cables presented below were tested with the Kramer 860 signal generator & cable tester. Results
from your installation may vary according to the video source signal intensity and display
specifications.

We recommend using Kramer PT-3H2 HDMI extender to extend the 4K HDMI signal, in case you
require a longer distance than the recommended cables or in case you find that the video image is
unstable.

achieving 4K@60Hz (4:2:0) resolution.

As noted in the table below, the CA-HM cable at 82ft needs an external power source (via micro-USB)
to achieve the maximum resolution. All shorter lengths in this cable model achieve the maximum
resolution without using a power source.
