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.

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

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.

Why do you have to call out my Factorio playthrough
-
no, it's meant to look like that

Remove the ground pin and it'll work fine. Just make sure your insurance covers electric fires.
-
Either way, really, the cord isn't grounded

This would be a decorator pattern. Not sure if this is the right use case tho
-
It works for now, we can refactor it later.

Narrator: But they never did.
-
I remember doing this and then refactoring my code twice.
At least I did it before handing it over.

Where do they have power sockets with two round European-style pins and two flat North American-style pins, and what voltage comes out of them?
-
I’m pretty sure it’s a “shaver only” socket so it would be 110V, 200mA, but at 50Hz.

I kind of expected it to spark and smoke a bit when plugged in. To be accurate.
