Do I need a cable for a Fire TV Stick or Roku stick?
No. A streaming stick plugs straight into an HDMI socket on the TV. You only need its power cable plugged in, and a short HDMI extender if the socket is too tight for the stick.

How to connect it
- Plug the stick into an HDMI socket on the TV, using an extender if it doesn't fit.
- Plug the USB power cable into the mains adapter, not the TV's USB socket: TV sockets often don't give enough power.
- Switch the TV to that HDMI input.
Worth knowing
- If the Wi-Fi is weak behind the TV, Amazon sells an Ethernet adapter for Fire TV sticks, or a box with a network socket is the better choice.
