How to connect a Samsung C27F390FH monitor to my Mac mini’s USB-C port?
I am trying to figure out how to connect a hand-me-down Samsung C27F390FH monitor to my Mac Mini’s USB-C port. What I have right now is a VGA cable attached via an adapter to a USB-C port on the Mac. I have plugged the VGA cable into the back of this Samsung monitor. But I am not getting any response from the Samsung monitor. All I get is a floating dialog box that says check signal cable. Can I connect this particular Samsung monitor via VGA to a USB-C port on a Mac?
The Samsung monitor has both D-sub and HDMI ports. As recently as two days ago the monitor worked in HDMI for someone else. For the moment, though, I want to use VGA. One reason is that I have an adapter for USB-C to VGA. I do not have an adapter for USB-C to HDMI. The other reason is that I am not yet sure where the problem lies. I am replacing another monitor that is only VGA. It started failing last week. I have read at least four threads in MacRumors that the Mac can have problems with external monitors plugged into an USB-C port. I have to consider the possibility that the problem might not be in one monitor or the other. I wonder if the USB-C to VGA adapter has gone bad. Or is something off in the Mac OS?
This is why I ask about the Samsung C27F390FH. I need to see if I can rule it out.
