I have a Lenovo laptop which I often take out to do presentations. I want to hook up my bluetooth speaker and a 40 inch smart TV as an external monitor in able to have a big screen so that people in a large area can see the screen image and hear the sound.
I have successfully connected my large bluetooth "party" speaker. However as soon as I plug the hdmi cable in, connecting my big screen, the bluetooth connection goes away and the sound comes out of the TV's built in speakers.
Surely there must be a simple solution to this problem.
Change your audio device back to the bluetooth speaker.
If you are trying to avoid doing this each time then you can pair it with the TV instead of the laptop or use a wired connection from the TV to the speaker if it has an input you can use.
