Ok, to start I have a bit of experience with Debian on Pi 3b's and Zero/Zero 2w's with dsi and spi displays so I thought this would be just as easy, but apparently I'm missing something.
I'm working with an Eleclab 11.26 inch 440x1920 lcd with HDMI input, a 4b 8gb, a Logitech G502 Proteus Core, and a homebrew keyboard using a Teensy. Power is coming from a 4 amp wall wart and since I was having issues, I chose to not power the display with the Pi so the display has it's own 2 amp power supply. SD card is a legit Sandisk 128 gb if that matters, since it was pulled from a working handheld computer with a different display.
The current output from it is rotated and shifted to the far right edge of the screen. What is displayed is blurry, like it's displaying it twice but just one pixel off. On top of that, what is displayed has what I guess would be interference or something. There are green, static-like lines running the full width of the display through what seems to be smearing and fading of some sort.
I've tried Ubuntu, Debian, Raspberry Pi OS, and Fedora (what I'd prefer). I've edited my config.txt with hdmi_force_hotplug=1, hdmi_ignore_edid=0xa5000080, hdmi_group=2, hdmi_mode=87, hdmi_cvt 440 1920 60 6 0 0 0, hdmi_drive=2, and display_rotate=2 with a few ways I've found or knew to attempt to rotate the screen. The display works just fine with any other input through HDMI. Both my laptop and video capture rig read the resolution correct and have the correct rotation, so I'm lost on what might be causing the display to mess up with the 4b and a Zero 2w. I can't let the install run completely through and try to access settings for the display so I'm not sure what to do from here.
I recorded a short video of what it does to show, I'm just not sure how to link it here since I've not been on a forum in years.
