The other question, is what's the physical connection - are you using different cables or adapters to connect a display to a Thunderbolt 3 equipped mac, vs the Thunderbolt 1 or 2 of the 2012?

There should not be any need to use Thunderbolt (as opposed to MiniDisplayPort, HDMI, or USB-C) on the Mac side. Likewise, use of the VGA port on the monitor side should be a last resort.

Yeah, but his machine only has TB3/USB-C ports, so it's going to need a different adapter from however it was plugged in to the older Macbook Pro, so there's the variables that need to be addressed - macOS display settings for the monitor, display cable, display cable adapters.

I see a number of USB-C to DVI-D adapter cables on Amazon, but the listings are a bit confusing.  Some of them claim 4K support, but then when you drill down, you find that there is a 1920x1080 or 1920x1200 limitation that is the hallmark of single-link DVI.
