And HDMI itself isn’t a great choice if you’re hoping to let people use old monitors.

I have an old one with DVI and VGA, so I have a DVI-HDMI dongle and HDMI-HDMI mini cable and my first dongle didn’t work because the form factor of the monitor case didn’t allow it to fit. Quite a pain.

Of course DVI would rule out old TVs, so I don’t know what the “best” choice is, if there is one.
