So If you have an old TV or monitor without an HDMI port then there are two possibilities. Your TV should have an AV port or a VGA port. So there is an easy solution to fix this issue. You have to get adapters with the HDMI female port which will work as an intermediate between two devices.

For a TV with a VGA port, you will be needing HDMI to VGA converter and for a TV with av port(CRT TV), you will need HDMI to av converter. Mi TV Stick in CRT TV
