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.
Maybe. By including VGA, the signal will be converted from a digital signal to analog, then back to digital. This might affect visual quality and color reproduction, and limit max resolution to about 1080p.
Oh yeah, it probably kills the quality, but we only need it to look at the terminal output of the Raspi while it’s booting, so quality really doesn’t matter…
Surprisingly, it does, yeah. Beforehand, we had independently tried hooking up a Raspberry Pi 3, which has a normal HDMI port, and we had tried two different HDMI-to-DisplayPort adapters, which wouldn’t work for whatever reason. So then seeing this chain of three adapters work without problem was kind of amazing.

Digital to Analog to Digital. Just order microhdmi to dport?
But it works, yes?
