Been looking for a 5v 5"-ish display to hook up to the composite output from my GoPro and power from a USB line.
I managed to find this, (picture hopefully attached) which looks like a converted 12v car display... which I believe someone has altered. Although how, I can't see. Anyway, it failed with an out of sync display. The seller sent me a replacement, but that doesn't work either.
Back to this display... I used a Chinese DC transformer to up the line to about 7v... and then it worked. All fine and dandy... but the transformer screams like a mini-banshee.
I've got no clue how to take this forward. Any advice would be gratefully appreciated.
Incidentally, I attached my jpeg image, and then the system said I couldn't post. Only jpg allowed. So I returned to the post, renamed the image, and then did a post to be told that I had already posted less than 30 seconds ago. So they I waited the required 30 seconds and submitted again... and was then told that I'd already posted this topic... but I can't see it. Please... somebody save me!) - (I had to create a new post and cut-paste everything over. *sigh*)
