HDMI 5" Display Backpack - Without Touch (ID: 2232) and PI 4

Hi,

I'm testing a batch of 'HDMI 5" Display Backpack - Without Touch' we received earlier this year.
We did noticed that lastest OS on Raspberry Pi 4 does not allow to display any image on the TFT (absolutely nothing, backlight doesn't seems activated).
We also used an external power supply for the TFT to be sure that the TFT was powered @ Pi 4 boot time... still nothing.
The config.txt has been modified modified accordingly to the tutorial (including audio output and hdmi_drive=2)... still nothing.

The TFT are however running on older Pi version (older version of the OS on Pi 2 (I have under the hand).

So I'm figuring a configuration issue regarding the new video driver of the Pi 4.

I have the same issue with 7x 5" 2232 displays but with Windows 10. I have an older batch 2260 displays and they work fine on Windows 10.
When I connect the 2232 to a laptop, no display is found. When I connect the 2260 to the same laptop with the same cables, it recognize the display, set the resolution automatically and is working!
Who can help getting these 2232 displays up and running?
