What did dude think was coming out of the VGA port? Tiny photographs? It’s all electricity through wires, of course it’ll send some electricity into a phone

It’s sending out the pixels, silly! A stream of little pixels in neat little rows.
TimeNaan@lemmy.world 14 hours ago
Yeah but is the voltage correct? It should be 5V to charge a phone over USB, is that part of the VGA spec?
Anivia@feddit.org 8 hours ago
Doesn’t matter. The VGA to HDMI adapter is active, not passive, so it matters if HDMI has a 5v rail, not VGA
9point6@lemmy.world 11 hours ago
Yeah I don’t think there’s a 5V pin for VGA.
I think if we had the scenario where we had a higher voltage than needed, we could have a toasty voltage regulator making something happen, but going the other way would need boost circuit unlikely to exist in these parts, in my understanding

I don’t know shit about cables but it’s plugged into a monitor. My intuition is that a monitor shouldn’t be pushing power out through a video input port.
pivot_root@lemmy.world 13 hours ago
DisplayPort has a +3.3V 500mA pin specifically for pushing power. In theory, great for powering an active adapter. In practice, has killed motherboards because Dell can’t design a computer for shit.
VindictiveJudge@lemmy.world 13 hours ago
The monitor has to send some data to the computer to tell it what screen resolutions it accepts. VGA, HDMI, and DisplayPort will all do that for sure. Less certain about component, composite, and S-Video.

Of course electricity comes out of a VGA port, but it's only a signal, I wouldn't assume that it's anywhere near enough to charge a phone.

Pin #9 of the VGA spec is 5v, though it seems unusual that a monitor would provide power on that pin
outhouseperilous@lemmy.dbzer0.com 13 hours ago
The VGA port on a monitor is an input.
RememberTheApollo_@lemmy.world 6 hours ago
The micro is probably charge only, no data. So no signal.

Even with a data-capable cable I don’t think most microUSB ports have video output capabilities. You’d have to find a cable/adapter specifically designed for video out, and a device with the explicit capability (usually cameras and phones).

Yup. VGA - HDMI and HDMI - USB should be working as intended. I have a HDMI - USB-c for my tablet’s second monitor that works just fine.

yeah? well I have a
wall outlet › USB-A › Micro USB › USB-C › THC
adapter, how about that? (it just ends in my rechargeable cart)Viking_Hippie@lemmy.dbzer0.com 14 hours ago

You convert electricity into tetrahydrocannabinol, the principal psychoactive constituent of cannabis?
Neat!
ChaoticNeutralCzech@lemmy.ml 7 hours ago
MicroUSB does it with MHL, which is the less addictive one

You get high from a wall outlet? Cool!
ivanafterall@lemmy.world 6 hours ago
You can convert USB-A directly into THC!? Since when!? I’m about to get so fucking high, I’ve got a drawer full of those old cables.
einlander@lemmy.world 15 hours ago
If you had an old HTC windows ce 6.0 it might work.
spazzman6156@sh.itjust.works 15 hours ago
Pretty sure those were mini USB.
halcyoncmdr@lemmy.world 12 hours ago
Just need another adapter.
einlander@lemmy.world 15 hours ago
Might be, I misplaced mine and I’ve been looking for it.

Am I in the minority of people who never used VGA?

The only time I’ve encountered VGA was my first year as an intern when my office had given me a flat screen monitor that frequently gave me migraines. Thing had to be older than me. That was 7 years ago.
If I encountered it before that, I wasn’t aware of it because I was a child and wasn’t responsible for plugging in the monitors I was using.

What did you use then? I remember cheap monitors in the early 00s ONLY having VGA. By the time I’d moved on, HDMI was so ubiquitous, I skipped DVI instead.

Very legitimate possiblity OP was born in the early 00’s

Cheap monitors at Walmart still typically have VGA available. Guess someone who’s buying a monitor at Walmart is a bit of a special case though.
LastYearsIrritant@sopuli.xyz 9 hours ago
If you were rich enough, could have only used displays with RGB-BNC.
Or maybe they’re kinda crazy and used Component video with a TV screen. (Or composite…)
Or maybe they’re just not that old.

I remember when CGA and EGA were normal and then this fancy new VGA came out but only on fancy high end computers and monitors.
Samskara@sh.itjust.works 4 hours ago
VGA was still very common around 20 years ago.
NotSteve_@piefed.ca 3 hours ago
It used to be that a monitor was fancy if it had DVI and really fancy if it had HDMI
uniquethrowagay@feddit.org 10 hours ago
I used VGA up until maybe 2012, 2013. Even longer at my job.
teslasaur@lemmy.world 8 hours ago
Thats cute. There are so, so many machines that have vga still in my field.
Basically every hmi panel in existence use vga still. And password-less vnc.

My old tower pc used to give wicked electric shocks off the hdmi ports. Pretty sure I could have run space heaters off those fuckers

IF the phone can output enough power with it’s OTG port AND has the correct drivers for that cheap-ass looking USB framebuffer graphics thing AND that’s an active HDMI to VGA adapter rather than some shitty vendor-specific implementation based on some unholy bastardisation AND the phone supports external displays… then I still don’t think it’d work, tbh (but it won’t (it might though (it won’t))).

Society if VGA over MicroUSB was standardized
