I purchased this as my video card only has 1 HDMI output, but I wanted to hook up two 4k TV's. I have a 43" which is used as the monitor then a 65" in the den. I have a 25 foot HDMI to reach the TV in the den, this adapter however did not work on that cable. It could be that the cable is too long. The screen would constantly flicker with bright greens and the sound wouldn't come through. However attaching it to the 6 foot cable to my monitor it works flawlessly at 4k x 60hz.

Excellent adaptateur pour brancher sur un écran un télé 4K. J'avais pas nécessairement besoin de 60Hz 4K, mais j'ai pris celui-là quand même si jamais je l'utilise sur une télé 4K, pour être sûr d'avoir du 60fps.

Works as intended.

good quality but need to unplug each time so the computer recognize it when I switch it from the computer to my Sony tv.

Seems to work alright, it's at 4k on my PC.

Works as advertised.
