The screen is a portrait display. The `dpi_timings` values relate to how the pixels are transferred over the DPI bus and don't have any effect on rotation etc. Either `display_rotate`...

For me with `display_rotate=1` I get the "Welcome to the Raspberry Pi Desktop" splash stuck permenantly on the display, and while I can hit "ctrl+alt+f1,2,3" etc to switch terminals they...

This may have something to do with the fact that there's one "pixel fountain" (pixel pipeline? pixel bus?) reserved for rotation on the Pi 4, and since the HDMI is...

Has anyone tried `display_rotate` this without `dtoverlay=vc4-fkms-v3d` in `/boot/config.txt`? It's clear this issue isn't confined to HyperPixel - https://www.raspberrypi.org/forums/viewtopic.php?t=246146 and: https://raspberrypi.stackexchange.com/questions/102182/display-rotate-3-only-filling-half-screen-raspberry-pi-4 Both suggesting that `vc4-fkms-v3d` seems to break this setting.

`dtoverlay=vc4-fkms-v3d` *must* be enabled for any of the new fancy HyperPixel 4 stuff to work. All the new Pi 4 multi-display support and X desktop rotation relies upon it. I...

Due to time constaints we generally only support Raspbian- there are too many unknowns with alternate distributions. The installer should probably check `/etc/os-release` and fail deliberately on anything else. It...

Might help that I have some outstanding PRs to add save-to-Xorg.conf functionality to the rotate utility. This should- in theory- work where there's no screen configuration (arandr) utility - https://github.com/pimoroni/hyperpixel4/pull/145/files

Does it work reliably when it *does* init? Looks like it could be a connectivity issue, but this isn't something I've seen before.

@R0B3RDV would these latest findings conclude that it's less related to heat and more related to some other issue with the display? I run my tests on a Pi which...

I've been running some tests of my own to see if I can replicate. If you have another failure condition, can you tell me what you see if you run:...
