Hi all.

This is my first post, I’m new in town. English is not my mother language and my device is on its way… from Japan. First of all I want to thank you all guys: I decided to get my Clockwork because of this community and also because I found answers to most of my questions just reading stuff you wrote.

Now, about the screen. I’m pretty much puzzled. I’ve [read](https://forum.clockworkpi.com/t/compatible-displays/4137) that

> [@Compatible displays](https://forum.clockworkpi.com/t/compatible-displays/4137/2):
>
> any display using the KD027-LCD pinout would be compatible (which is a LOT of them actually)

Then I found no info about that “KD027-LCD pinout”. By what I’ve seen here it seems the original screen uses a 40 pin connector and @hob286 is using that flex cable and an intermediate PCB to connect a 54 pin screen. I might have misunderstood, what I understood was this mod was 40 pin (motherboard) \> 45 pin (PCB) \> 54 pin (new screen). If so, why aren’t we using existing 40 pin screens? For example, would any of [these](https://es.aliexpress.com/item/32837085500.html) work without the need of the extra PCB?

I guess there must be a reason, because those are way cheaper (not to mention shipping fees). Please, help me understand this stuff. I want to learn and I could really use bigger screens… preferrably with aligned pixels. By that I mean:

I’d love a 480x320 screen, I could use a 640x480, but then I’d have to be able to switch back to the original screen mostly to test my games work and look as intended. I can 3D print faceplates and keep screens attached to them, but I’m in if it’s a **reversible** mod. I wouldn’t really _love_ purchasing extra screen modules just to strip them and mod them. Would that be the only way? It’s not, right? Right?

Thanks in advance!
