Hi,  
I have issues with the external monitor. I am connecting the tablet using:  
1- Micro hdmi to VGA

result - Nothing.

The adapter is working fine (tried with a raspberryPi 4)

2- If I use Micro hdmi to hdmi

I can see the extended desktop but the colors are not right. EG I can see blue lines where the screen should be Black

Any ideas?
