Output, not input.If you read later on the datasheet, it says it is compatible with YCbCr output
And it could be less than 5 dollars a screen if you make an offer they accept.

Sweet deal! I bought a second one for $10 and he shipped 2 (again). So I’m at 4 screens for $20!Just got my order of 2 screens, and there were 3 inside! Cool, that’s $4 a piece.
Easiest way is to look at the driver board and find the chip with 8 large legs. That's normally the regulator that steps the input voltage down to 5v. You can use a multimeter to check the voltage of each pin. Once you find one outputting around 5v, you can just wire your 5v supply to that pin, forgo higher voltage and it'll run. Just be REALLY careful when checking the pins. I've killed boards by accidentally bridging 12v to 5v with a slip of the multimeter tip.How would I go about figuring out if this display can run properly off less that 7.5v? I’ve got some of the boards I want to start using, but it would be way easier if I could get it to run from 5v or 3.3v.
Slick, thank you!Easiest way is to look at the driver board and find the chip with 8 large legs. That's normally the regulator that steps the input voltage down to 5v.

Check the voltage coming out of that 3 legged component you have marked, that could be the 3.3v reg.Slick, thank you!
For anyone else wondering the same, I did some testing and found you could use either of these two points (in red) as a 5v input to make the display function. They are both continuous on the same line so it shouldn’t matter which one, but the larger of the two might be easier to solder too.

When I got mine I made an offer as well that got accepted, so you may be able to make an offer of less than $50 and get a better deal!For anyone still thinking of getting one of these, it looks like the seller stopped selling them individually. However, you can get a lot of 10 for $50. At $5/screen, how can you go wrong? I’m thinking of doing that and being set for life.
I tried what stitches suggested, but it didn’t seem to work. I’ve only been able to get 5V out of it. If anyone has any other ideas I’m happy to try though!So did anybody ever figure out if this screen can be run off 3.3v? And did anybody find out how many watts this runs at? Because if it could run off 3.3v, that would be very convenient, and more efficient because it doesnt have to go through another voltage regulator.
