I bought a Picade 8" version at 2018 and bought a “Picade 10-inch Display Upgrade Kit” at 2020. It works well with my Raspberry Pi 3B. Last week I bought a Raspberry Pi 4 (8GB) with a USB-C version Picade X Hat from Pimoroni for upgrade. When I begin to config the keys for 1-2 minutes, the screen going brighter and brighter. Finally it turn into pure white, and 4 corner become black (as photos shown), even if I plug it back to my old Pi 3.
I connect the screen to Pi 4 HDMI port 0 with a HDMI to micro HDMI converter. The power of screen is connected to the USB 3.0 port of Pi 4. I have tested the Pi4 work well with other HDMI monitors.
I found that the screen upgrade kit is now called “HDMI 10” LCD Screen Kit (1024x768)" in Pimoroni. I want to know is the screen and controller card the same as I bought in 2020? Is my 10" screen is crashed? Is the 2020 version suitable for Pi 4 (Voltage changed or something)? If the 2020 version is not the same as now selling in Pimoroni, is current one work with Pi4, or I should provide another power source to the screen to prevent it crash?
