Now the repeaters added to the end of the 15m cable and go from there again 5m to the projector, cast. So 20m. The signal transmission is fine, the 720p / 120HZ be transmitted without errors and also the display information with looped through.
As already mentioned, the device also has a power connector, but I do not know what is supposed to be good, because it wonderfully without work and also I could not find any information on how this should be to join, since volts and watts information is missing.
Incidentally, this device is no bigger than a matchbox and has apparently gold-plated contacts (whether this is real gold, I do not know). It was produced in China, the workmanship is not premium (if I rattles shake something inside) seems otherwise but to be fine.
However, my copy was contrary to the description not of Logilink but of goobay and was probably imported from China by this.
Moreover, it came without packaging and only in a padded envelope.
For these small things there are in total a deduction of points.
Otherwise, this part does exactly what it should and has my absolute buy recommendation.
NOTE: It is important that the repeater always possible added to the end of the line. As I have the cable tentatively reversed, the repeater so after 5m cable and then the 15m cable've put to the projector, went back only 1080p / 60Hz. This is certainly also depends on the cable, but the distance between the output device and the repeater should not be too long if you want to transmit with 120Hz. In addition, as already mentioned by previous speakers pay attention to input / output!
