just a couple of things to clear up...

the one your recommending is slightly different to the one you purchased on ebay (based on your ebay link)

the pin layout is the same, but the board is slightly different....

was your screen a ILI9340 or ILI9341, as the ebay screen is showing to be ILI9341
Nice catch! Looking closer at my boards (as I've had a few delivered from different sellers), I actually have *both* and they both work fine with the same configuration. I'll update my post.

As I said it's been hard to find any concrete info on the difference between 91 and 90 (much less which one is which in images) - you're saying the one in the image with yellow header-pins is the 91? Do you have a source? Even sellers seem to be confused - the ebay seller actually lists it as both the 90 and 91: https://www.dropbox.com/s/mk70egmak5ynj ... 8.png?dl=0

also, i've been searching for this screen for about 2 days now, and i have a niggly feeling the screen may now be obsolete (hopefully wrong)

as i've contacted dozens of suppliers/sellers over several portals/websites

Alibaba... the wholesale suppliers that have come back to me (still waiting on some) have all said its an old screen and no idea of restocking
That really sucks if that's the case. :( I'm still waiting on my 2.4, but in the meantime I guess I can 3d-print one based on the schematics people have posted. Not sure what to do at this point: wait and see with the 2.2? Make the 2.4 work, whether it's out of the box or a custom board it attaches to? Regardless, I'll have to have both 2.2 and 2.4 models ready, I guess, as I'm sure lots of folks have purchased the 2.2 in preparation. Really frustrating - that screen was easily found all over the place not long ago.

dont really have a source, only going by the listings (i agree, i dont think these sellers know)

the ebay link you provided http://www.ebay.com/itm/252135075697
has the screen listed as ILI9341

funnily enough, the screens i've ordered (still waiting to confirm if its genuine and theyve got them to ship) have images of the second board you recommended (Black pin headers) and theyve listed that as ILI9341

now that being said, i've seen a listing from the same seller for the other board (yellow pin header) stating thats ILI9341 :?

i've messaged them about the ones that i've ordered and the others i came across, but as there in china (time difference) getting a reply back means waiting several hours (depending on what time i messaged them.... )


i'm kinda hoping the 2.4 fits in now...

eBay Germany has them as well for 5,5€...

Coming from China so takes a while but the price is really good considering its exactally the same screen wermy uses ;)

Right, read the whole listing (or the top and bottom of the screenshot I posted), that seller actually says it's both a 9340 and 9341. Confusing to say the least. :?

2.4" would be nice. I'll have a much better idea tonight of whether or not it will fit out-of-the-box or if we'll need a standalone screen with custom board.

Can you post a link to the one you bought? There's a good chance it's the much-lower resolution screen that you likely won't be happy with. :\

Edit: Found it. The picture they posted doesn't match the pin configuration they list int he description. I think they have the wrong picture, and I bet it's actually the lower-res one. Or there's the chance that the picture is correct and the description is wrong.

These ebay sellers are a mess!

That's certainly an option. Hopefully the 2.4" ones on the board squeeze in there - I'll find out tonight. :)

the only problem i found when i was looking for my 2.2" bare screens, the prices they were quoting on alibaba listings were nothing like the actual prices they gave you when you asked them for quotes!!
