Last week at $DAYJOB, we wanted to connect a Raspberry Pi 4 to a monitor. Raspberry Pi 4 has a Micro-HDMI port. The monitor has DisplayPort and DVI.
So, we went to IT support to see, if they have anything to make that work. Well, only thing they have with Micro-HDMI is an adapter that brings it onto VGA, because that's apparently an adapter someone needed.
Now you'd think they might have VGA-to-DVI, but nope, we had to route through normal HDMI in between. So, the chain of adapters we now use is:
Micro-HDMI → VGA → HDMI → DVI
Oh, and for good measure, the HDMI-to-DVI adapter also has a USB-plug dangling off the side, which definitely won't get routed through VGA.
