Monitor won’t connect
I have a brand new Mac mini and I am trying to connect an old Dell monitor using VGA cable to HDMI and it says there’s no cable connected
Question marked as
What model is the Dell monitor and what other inputs does it have?
(most likely the old monitor has VGA & DVI inputs)

For VGA out to the monitor, you need a USB-C to VGA adapter and VGA cable.
For DVI out to the monitor, you need a USB-C to DVI adapter or an HDMI to DVI adapter and DVI cable.
You can setup the Mac mini by connecting it to most any HDMI TV using an HDMI cable.
