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 ?
MacBook Air (2020 or later)

Hello pokai256! We're glad to hear that you're able to get your ViewSonic monitor to connect. This article may be useful: If your external display isn't detected or appears blurry on your Mac
If you still get no signal with your LG TV and Samsung TV, connect with the manufacturers of those devices to troubleshoot further.
Cheers!
