The cable is quite bold isolated, but this somewhat rigid.
However, it has already seen a number of turns, because I had to try first, as I laid there.
Ultimately, it is located in a cable duct and at least once by 90 degrees "bent" - no problem.
Isolation - ie the cable from the outside - is a dark blue plastic coat.
The contact surfaces are gold plated - although I still could not explain why this should be good.
(Not even professional XLR audio cable for studio use are gold plated)
The cable including plug makes a stable impression and it works smoothly. I use it now for about 6 months.
I use the HDMI cable, to send an image from the Sony multi-channel AV Receiver STR-DN1000 to the projector Epson EH-TW 3500.
Here, the receiver signals from a PC or Blu-Ray player passes in Full HD (1920x1080) without audio signals (image only). The Blu-ray player in full HD come more than 24 frames / sec.
The PC indicates that it outputs a frequency of 59 Hz in 1920x1080. And so it looks. Beautifully liquid so as you know it from your computer monitor forth (there are no photos swallowed). There is no jerkiness or irregularities let alone any errors.
An HP notebook Pavilion dv9000 series could also send us an interference-free picture to my beamer through this cable.
About contrast or image quality I do not need to philosophize here, because that is out of place in a digital transmission. This option copies the zeros and ones with an HDMI cable, that is, either it works or it is equal to total failures. A change in the image quality can not take place.
Compared with other HDMI cables, for example, G & BL or a "cheap cable" has this HDMI cable from Grundig a slightly slimmer connector, which is nevertheless robust.
Picture & Sound as a HDMI signal by simultaneously send I did not try, because I do not need it in such a configuration.
And more I can not remember this one also. Cable goes - all good.
