Poorly shielded, no CEC.

A detailed description, including experience report:
We have our apartment remodeled. All inclusive, ie with its own wall pipe for flat-wiring. I had two good HDMI cables lying around, but they were unfortunately too short. So I thought to myself as a technician: HDMI is digital, what can go wrong. And 1.3 is also the cable, the skin-friendly way.

Chapter 1: Kollateralspaß
The cable connects my home theater system with the TV. Everything connected to television, fits. I switch the home theater system - away> TV picture. ?????? Home theater from image back.
Since I had to laugh briefly, because I with the best intentions could not explain how something is possible.
After often practiced one-after-the-other-unplugging procedure I come on it that it is the HDMI cable. The fact scatters yet so strong in the (also laid in the wall) antenna cord, that the reception for Digital TV on television falls below the level decodable.
I've got it fixed, as I have the HDMI cable 2 times through the ferrite core supplied from the home theater system. The would be meant for the Ethernet cable, but also fulfills its purpose here. Nevertheless, the disturbances are still so strong that sometimes signals to HD arise artifacts.

Chapter 2: CEC
I specially a Samsung home theater system for my Samsung TV bought, so the TV is not so lonely and has with its neighbor to talk what. Technically, the CEC calls (Consumer Electronics Control) and is meant that you have to operate separately not just for the volume control both units and for example, only has to turn one and the other goes along the same. This usually goes on HDMI 1.3 and is made via pin 13. Again, I have a configuration problem thought, because the specification is indeed adhere well.
Nope. After just a few minutes playing around on TV and HK system an external AmazonBasics tried it worked right away. Now my TV is also sad because he thinks he is alone again until.

Chapter 3: The plug
Somehow the plug is not the truth. The gold from the gold plating may come from the stopping of a company employee. The contact quality, it does not contribute in any case. This manifests itself by the fact that sometimes the image briefly breaks, my television confused, looking left-right and brings perhaps after 1-2 seconds a picture because he takes it that it is not yet closing time.

And the worst: My wife laughs at me because she finds it very funny, if I as a meticulous man get no reasonable picture on the TV. Who will replace me, please? This disgrace!

Konlusio: Purchases. There. Not.
Mir remains (down TV, cable re-feed) nothing else than an operation on an open wall to carry out and to banish the problem with a gscheiten cable out of my life. With two children it has nothing else to do.
