connecting MacBook Air to Samsung TV with HDMI cable
When I connect my brand new (!) MacBook Air to my Samsung TV using the Apple adapter and an HDMI cord, it works fine as a second screen. When I do the same set up to connect to my mother's Samsung (newer than mine) TV, I can see what is on my MBA screen, but it jumps constantly. What requirements are there on the television for this to work? Any ideas to fix this problem?
MacBook Air 13″, macOS 11.0
