external monitor goes black
I have a MacBook Pro running Ventura 13.0 and connected an external monitor. The monitor is recognized and visible in "Displays" but goes black every other minute or so. It is not the monitor as I returned the first Dell monitor thinking it was defective after I switched out the cables and Apple adaptors. I bought a new more expensive monitor thinking it was the quality or manufacturer and no - immediately the same thing. I was told to select "variable" on the refresh rate and there is no such option with Ventura. Apple support (4th person) scheduled me for a Genius Bar appt. but knowing they only have Apple products - I canceled it. I should be able to connect an external monitor regardless of the manufacturer.
Anyone out there experiencing the same?
MacBook Pro 13″, macOS 11.6
