The HDMI switch looked to me very well and would probably also worked well with power cables. I do not know if the cable has been forgotten or whether it is generally not present in any case, the connection is interrupted briefly during my first film every minute, because the power of the HDMI cable apparently was not enough. I still give 3 stars because I do not know whether the power cable is generally not present and because I have just received a Rücksendettiket and hopefully get my money right back.
