I  only have one HDMI port on my old 50" plasma which is already in use. I could do with a couple more and wondering how well these things work? https://www.lazada.co.th/hdmi-3-port-switch-hdmi-switch-3-1-hdmi-9924413.html?spm=a2o4m.search.0.0.558c6137IqbK3n&ff=1

I have 3 of them, bought at different times and (probably) from different sellers on Lazada. All work very nicely and automatically switch to whatever you turn on - but don't have more than one accessory switched on at a time, as the switch will just connect to ONE of them.  Mine are connected to TVs, where there is also connected a sat-box and Android box.

 

I paid a lot less for this switch - look around on Lazada, there are usually a lot of sellers selling the same product at different prices.

 

Remember - you'll also need an extra hdmi cable to set the switch up.

 

Cheers

 

I bought this switch at Fortune on Ratchada, but after a week or so I disconnected it.

 

The signal kept stopping and I kept getting a black screen

This works great for me.
