That’s VGA, it’s gonna be fine. Most wires are either ground or not used for actual image data. R, G and B are analog so noise on those just makes the output noisy, no big deal. That leaves us with HSync and VSync. They are digital signals with 3.3V between on and off and only a single pulse per line / frame so they’re also pretty robust against noise.
So unless you’re going for an extremely high resolution on a really cheap monitor over a long distance, the worst that will happen is that your image will look grainy like TV static. It would take quite a bit of interference before the sync signals degrade enough to not get any image at all.
Now I wonder if I can route VGA through unusual items. Cutlery, the railing on a staircase, swords, something like that. As long as I can find six pieces of metal of roughly equal length, it should work.
Q: So do you have any hobbies?
A: Well lately I’ve really gotten interested in routing VGA through unusual items!
Q: Ooooh, that’s so hot right now
Through your body with nippleclamps?
I’d need a couple more volunteers to make sure all signals have the same delay.
Ugh… Fine… Let’s get started.
This died with high-freq serial ports.
Honestly, couldn’t we just transfer only the changes? Instead of sending the same pic 60, 120, … times the second over. And how fast it can do the updating is the display frequency.
It could be done, the issue is there’s not really any reason to. This isn’t getting streamed over a network, this is one cable going from one device to another, there’s no reason to try and save bandwidth. If you start compressing the image to be able to run at a higher frame rate or such, more complex scenes will literally display worse, due to not being incompressible in that way, which seems… undesirable
