I recently bought the Telefunken XF49G511. Now wanted to connect via HDMI my Xbox, but no matter what I do, the TV does not recognize them. Have all HDMI connections tested, there's always no signal there. The HDMI cable is also not damaged. All HDMI channels are also activated. Does anyone know? /
What is it exactly for an Xbox?
If it is the Xbox One X or One S then the TV must support HDCP 2.2, if it is factory set to 4K resolution then it will not be recognized on the TV.
Xbox360
Check if your TV has the latest software on it, if not then make an update on the TV
