I’m using the gorgeous Pimoroni Hyperpixel 4.0 on a Raspberry Pi 4 for a small project. The display is crazy beautiful, and comes in a touch and non-touch version.
For posterity, I followed the directions above (running Pimoroni’s install script, choosing option 2 for Rectangular with Experimental Pi 4 Touch Fix, then edited
/boot/config.txt as follows. Modified lines commented as such.

Very pleased with this, though I’ve heard it won’t work with low-level access (ie. RetroPie setups). YMMV.
