I assume your display is DVI, so as @Amethyst1 suggests above.Wouldn't I need a MiniDisplayPort-to-HDMI adapter?
Right.I'm currently using this port(circled in red) on my 2009 Mac Mini. I believe it's a mini DVI port.
My monitor is currently connected to a 2009 Mac Mini but I'd like to connect it to a 2014 Mac Mini.
Yes I have a 20" ADC monitor. I have the ADC to DVI adapter which enables it to work with my 2009 Mini. I want to connect the 20" ADC monitor to a 2014 Mac Mini. Does the 2014 Mac Mini have the mini DVI port?Isn't that a 20" ADC monitor pictured? It will work but you will need the ADC to DVI adapter, and whatever else from DVI to whatever your computer takes. I've used a 22" ACD with ADC on newer Macs and on PCs. It can be finicky at times and doesn't seem to like some OSs with some adapters. I've literally used it with the same adapters on MacOS, Windows and Linux and had varying degrees of success depending on how it was connected.
No. It has MiniDisplayPort (Thunderbolt 2) and HDMI. So, a MiniDisplayPort-to-DVI or HDMI-to-DVI adapter is necessary.Does the 2014 Mac Mini have the mini DVI port?
