HDMI connection to TV?

I have a Samsung TV with 3 HDMI connections, which are all occupied (Sky receiver, Horizon receiver and laptop. Now I could very well use a 4th connection for a Fire TV stick (4K). Is there one for this suitable option.

You can do this with an HDMI switch, for example.
These have several HDMI inputs and one HDMI output. So you could then connect multiple devices to one HDMI input on the TV. Depending on the model, these switch automatically between the input signals or you have to do this manually.
