@MadScientist sorry for so many questions. But won’t I need to solder them in a “T”? Or get a T splice?

My point is that all the power supply’s under 80W only have one set of output wires.

@MadScientist
Will both the LCD and the step down wire to the same wire? Will this lower the 12 volts from the lcd?

@MadScientist with the pi and all?

@MadScientist wouldn’t that be the LTN170WX-L08 that i had to look up to find it? And thanks for the info on universal boards. Though I think I want the auto wake feature.

@MadScientist will this be on the back of the screen it’s self?

@MadScientist I think this one should be good. I’m currently at work so I can’t just look at it.

@MadScientist it is the recommended power for the controller board https://rover.ebay.com/rover/0/e11400.m1842.l5919/7?euid=5138ba89bae64ecd98354e79c15592eb&bu=44095069551&loc=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fvod%3Ftransid%3D1755030964001%26itemid%3D112175476566%26qu%3D2&sojTags=bu=bu
It’s an old laptop screen.

@MadScientist probably an ignorant question. But will that still work if split between the step down to a 5v, as well as the 12v controller board?

@MadScientist ok so you example is exactly the specs for my display. And from what I’ve seen RasPi3’s won’t reach 4 watts. So any psu over 40 should work, correct?
