I recently purchased the Adafruit 2.2 inches (no touch) hat and added it on top of my Pi 4.
I was able to follow and complete all instructions from their page without any issues.
However, the screen is always in bland white.
I tried all 3 options in their setup script (to set the screen up as a console, HDMI mirror, or none). Nothing works.
At one time, when it was in the HDMI mirror mode, it shows something like this:

I’ve tried a few times with different screens and ended up with a white screen as well. Tried reaching out for help but no one responded. In the end I gave up on getting a 2.2 inch screen working with my raspberry pi. I honestly think it’s a driver issue or configuration issue but it’s hard to tell since no one wants to support it.
The follow-up is missing from the forums, but Peter got in touch with us via email we went down a warranty pathway.
For Adafruit products like this one, Adafruit support forums are a great first port of call, as you can get in touch directly with the engineers who designed the product!
