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
Yeah but is the voltage correct? It should be 5V to charge a phone over USB, is that part of the VGA spec?
Doesn’t matter. The VGA to HDMI adapter is active, not passive, so it matters if HDMI has a 5v rail, not VGA
If, hypothetically, VGA didn’t have a 5v rail then how would power get from the monitor to the HDMI adapter. It would absolutely have to be a part of the spec.
It doesn’t need to be 5v. An active adapter can have a buck converter.
In reality active HDMI adapters get powered by the HDMI device though, not the VGA monitor, so it’s a moot point anyways
If the vga/hdmi adapter is active then this abomination could actually pass display information provided you had a micro-usb device that supported display out over usb (idk if there is such a thing and if so it probably doesn’t work all that well but still)
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 circuitry unlikely to exist in these parts, in my understanding
There is! It’s pin #9
Ah my memory failed me then! Thanks for the correction, I guess this is technically possible then!
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.
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.
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.
The VGA port on a monitor is an input.
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))).
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)wall outlet › USB-A › Micro USB › USB-C › THC
You convert electricity into tetrahydrocannabinol, the principal psychoactive constituent of cannabis?
Neat!
MicroUSB does it with MHL, which is the less addictive one
You get high from a wall outlet? Cool!
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.
If you had an old HTC windows ce 6.0 it might work. Like the HTC tilt 2.
Pretty sure those were mini USB.
Just need another adapter.
Might be, I misplaced mine and I’ve been looking for it.
The micro is probably charge only, no data. So no signal.
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.
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
This pissed me off so much that I accidentally backed out and up voted a post I didn’t even look at. Fuck you, sir.
Mission accomplished
Am I in the minority of people who never used VGA?
Emphasis on Minor I guess
The only time I’ve encountered VGA was my first year as an intern, my office had given me a 4:3 flat screen monitor which 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.
I used VGA up until maybe 2012, 2013. Even longer at my job.
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.
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.
VGA was still very common around 20 years ago.
