Tested LCD Screens

Tested_LCD_Screens.md

These are the LCD Screens I have tested or have been tested by a reliable source. Testing has been completed using OctoPi image, and raspbian. All should work with OctoPrint.

I have personally tested OctoDash, OctoScreen, OctoBTT, and TouchUI with these original 4 screens.

Commands tested

Testing dimming

DISPLAY=:0 xset dpms force standby
DISPLAY=:0 xset dpms force on

Testing brightness control

Check current brightness level

cat /sys/devices/platform/rpi_backlight/backlight/rpi_backlight/brightness

Set 50% brightness level

echo 128 | sudo tee /sys/devices/platform/rpi_backlight/backlight/rpi_backlight/brightness

Set 100% brightness level

echo 255 | sudo tee /sys/devices/platform/rpi_backlight/backlight/rpi_backlight/brightness

3. OSOYOO DSI 7" Screen

   3.1 DSI cable is 180 flipped (I.E. both pin sides are on the same side of the cable.) This will make it hard to use a standard DSI cable w/o purchasing an adapter like the one I used.

   3.2 There is also DSI to HDMI kit that might work the same.

@borderline667 DSI just works, no drivers needed. As long as the cable is connected correctly. Double check that.

I have the DSI waveshare 4.3. Is it the same than yours?
