Can you post some more photos of the working screen so that it is easier to compare. Also How do you find out the pin configuration of the ribbon cable side. I can see that the PCB is actually quite minimal with practically no components other than the ribbon holder.

Does this configuration work for all similar screens with 60 pins?

For this particular lcd all the pins and settings you need for the DPI are on the data sheet.

For reference:
https://www.raspberrypi.org/documentati ... rrypi/dpi/

The adapter is a 60 pin ribbon adapter i trimmed coz i cannot find any 54 pin adapter.

Will try to post some pictures when i get home.

Update: I have soldered the wires from the fpc adapter to the stripped Pi3.

Now it's time to test the screen via DPI mode. I'm using a dc-dc boost converter for the LCD's backlight.
It works!Show

To get your dpi working, you have to
1) connect the fpc to the correct pins on the board
2) change dpi overlay settings in config
3) supply proper voltage

Is that correct ? On the config side, it's just the single line of code(the overlay)?

Thank you ! Been thinking about working with this screen and I've been researching a lot and all the info I seem to come across has a lot more on the configuration side. Maybe I was just over thinking it haha

TinkerBoy I took a lot of inspiration from your work and I'm going to make my second build with a raspi3 and a dpi screen. Waiting for the parts.
Good job and waiting for updates!!

I mean where did you get the PCBs from. (pcb manufacturer ?)
