I have 3 sources (receiver, XBox and Chromecast dongle) But my LG TV has only 2 HDMI inputs. Therefore, in order not constantly re stuck here I needed a HDMI switch to switch. I have now connected the XBox and the Chromecast to the switch, and switch to using the button between the sources, which works flawlessly. What does not work (at least I did not have an external power supply connected) is to operate the receiver to the switch. Here the image flickers only. But as he met my needs as a result, I will keep it.
