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.

But it works, yes?

[–] Ephera@lemmy.ml 1 points 38 minutes ago

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.

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.

[–] Ephera@lemmy.ml 2 points 36 minutes ago

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...

Why do you have to call out my Factorio playthrough

Remove the ground pin and it'll work fine. Just make sure your insurance covers electric fires.

[–] Trex202@lemmy.world 2 points 8 hours ago

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.

[–] ulterno@programming.dev 7 points 20 hours ago

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?

[–] JimVanDeventer@lemmy.world 1 points 1 hour ago

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.
