Excellent cable and very high quality, the only reason I give it 4 stars is that its max rate is 3840 x 2160 @ 30 Hz while I wanted it at 60 Hz

When connected to a PC with a 4k monitor at 60hz, it initially has instant disconnections (black screen and then comes back several times). If the monitor is set to 50hz, it works correctly. Do not buy it.

Very poor quality of viewing. In the first half hour, it makes 'snow', which then disappears on its own. It was tested on several devices and it does the same everywhere.
