To The Product:
The image was transferred immediately to a Samsung TV from a Thinkpad T420. The sound quality is very good (from the perspective of a non-skilled person) and is not for a direct HDMI connection from the desktop PC.
The workmanship is good, nothing rattles or creaks, the cable is very thick and will hopefully not bend too quickly or having a loose connection.
Attention, so nothing is broken: If you remove the adapter from the DisplayPort, a small terminal must be pressed down, enter the two small metal teeth, which are intended to prevent a simple drop of the adapter during operation. Do not pull with force, but only press adequately, then he can pull up easily.
