I bought at the signal via the above-mentioned 3m cable and then a normal 1.2m cable to extend this adapter. Unfortunately, this has had the consequence that there was "Pixel error".
Now I have the signal on 3x1,5m cable run with 2 adapters and it works just fine.
This is only for information because I do not know why these "errors" occur. But this still wanted the people who might buy this combination give to the path.
Since I do not know what it is, and the adapter does his job, I still give it 5 stars.
