Review on WARRKY 4K DisplayPort to HDMI Cable Adapter: High-Speed, Aluminum Shell and Nylon Braided Cord for Dell, HP, Samsung, and More - 6FT by Ka Sem ᠌

I had to return it because the adapter only works in one direction: DP on the HDMI video card on the monitor. In my case, the opposite was necessary: ​​connect the HDMI in the laptop to the DP in the monitor. The description does not say anything about these restrictions. As, in fact, not a single word at all. Just not a word of description. Therefore, faced with such a problem, I had to study the issue on the Internet. It turned out that the problem is widespread, and as far as I understand, it is about some kind of licensing restrictions. I don't remember exactly which side. As a solution, there are Chinese USB-powered shoelaces that work exactly in the opposite direction (but also only in one direction).
