inakustik offers its own 2m High Speed HDMI Cable if you want to link up your 4K TV with a 2 m or 6.6 ft HDMI cable. The inakustik 2m High Speed HDMI Cable uses HDMI 2.0 to support 4K HD, 3D video, 2160p (4K@60Hz), Audio Return Channel (ARC), multi-bit deep color, additional color spaces and Ethernet along with CEC, HDCP and EDID compliance as shown on its packaging.
In case you need a longer 3 m or 9.8 ft HDMI cable, you can opt for the inakustik 3m High Speed HDMI Cable that also shares similar specs as the 2 m cable.
Using the GRL DI20 cable tester to test the insertion loss through the inakustik 2m High Speed HDMI Cable, we can see the cable has about the same overall signal integrity performance when compared to the StarTech 4K HDMI Cable (2 m) where they are both the same length. The inakustik 2m High Speed HDMI Cable despite being the more expensive cable however has higher loss under 10 GHz compared to the cheaper StarTech 4K HDMI Cable (2 m) (see review here).
Here's a quick look of the inakustik 2m High Speed HDMI Cable that we purchased from a MediaMarkt retail store in Germany.
