Adafruit 5" 800x480 display mount

Mount for the Adafruit Industries HDMI 5" 800x480 Display Backpack - With Touchscreen.

I got mine at Microcenter: https://www.microcenter.com/product/613550/adafruit-industries-hdmi-5-800x480-display-backpack-with-touchscreen

SKU was 006676, part number is 2260.

I use it for Klipperscreen.

BOM: 

4x M3x6mm (maybe 8mm would be easier) bolts

1x M3x10mm bolt

5x M3 nuts

4x construction screws

To get this display working on my pi4 was a major pain. The guides online didn't work. The resolution was constantly completely wrong.

I installed KlipperScreen using kiauh, then:

I added these to /boot/config.txt:

hdmi_group=2
hdmi_mode=87
hdmi_cvt=800 480 60 6 0 0 0
hdmi_drive=1

max_usb_current=1
 

In /boot/config.txt, I changed this:

dtoverlay=vc4-kms-v3d

to this:

dtoverlay=vc4-fkms-v3d

I created the file /usr/share/X11/xorg.conf.d/90-monitor.conf which contained the following:

Section "Monitor"
   Identifier "HDMI-1"
   Modeline "800x480_60.00"   29.50  800 824 896 992  480 483 493 500 -hsync +vsync
   # This identifier would be the same as the name of the connector printed by xrandr.
   # it can be "HDMI-0" "DisplayPort-0", "DSI-0", "DVI-0", "DPI-0" etc

   Option "Rotate" "normal"
   # Valid rotation options are normal,inverted,left,right

   Option "PreferredMode" "800x480_60.00"
   # May be necesary if you are not getting your prefered resolution.
EndSection
 

After that, I rebooted, and it worked.
