Hi,
I had exacrly the same problem. Support for the 4.0 Frame is only available in the pre-release version of the Pimoroni pico code (1.19.11) not the release version (1.19.10). You’re trying to run the board with the code that’s supporting the 5.7" frame.
You’ll need to download the latest code from here: Release Version 1.19.11 · pimoroni/pimoroni-pico · GitHub
Also, in the source you’ll need to set:
from picographics import PicoGraphics, DISPLAY_INKY_FRAME_4 as DISPLAY
(rather than DISPLAY_INKY_FRAME)
This is highly frustrating - They sent out a mailshot about the 4.0 board last week which meant that lots of relatively inexperienced people (myself included) will have purchased one only to find that it doesn’t work properly when running the getting started tutorials. I still can’t make the networking function and I suspect it’s something stupid that I’ve done but am yet to find out what.
Good luck!
