The KabelDirekt 4K HDMI Cable is an option for a 30 ft / 9.1 m HDMI cable to link up your 4K or HD TV's or displays, as well as computers or other devices that use the HDMI connector. Germany based KabelDirekt offers 4K@60p HDMI signal frame rates with HDR, 18 Gb/s, 1080p Full HD, 3D, ARC, and Ethernet support for its cable that also comes with full metal shielding.
Using the GRL DI20 cable tester to test the insertion loss (IL) through the KabelDirekt 4K HDMI Cable, we can see the cable has much lower overall signal integrity performance when compared to the Monoprice Certified Premium HDMI Cable (30 ft) even though they are the same length. The KabelDirekt 4K HDMI Cable also has higher loss under 10 GHz compared to the Monoprice Certified Premium HDMI Cable (30 ft).
