I tried to connect my Macbook Air M1 with an external monitor with HDMI. I can find the external monitor in Display preference on Mac. However, there was no signal on the external monitor. What can I do the next ?

If you still get no signal with your LG TV and Samsung TV, connect with the manufacturers of those devices to troubleshoot further.
Cheers!
