Hello Gouwa and thanks for your quick reply
So here are the specs I gathered.
As for the monitors, we so have two models :
- the 1st one has a native resolution of 1280*1024 at 75Hz vertical refresh rate and 80Hz horizontal (these are Hyundai IQ17 monitors)
- the other one has a native resolution of 1440*900 at 75Hz vertical refresh rate and 80Hz horizontal (these are Asus VW192S monitors)
The two HDMI to VGA adapters I tried are specified to output up to 1920*1080 at 60Hz max. One is branded Ugreen and the other Raukie.
Lastly, I only tried with Vim Ubuntu 16.04 V170102 as I don't dual boot ; connected directly to a HDMI monitor, it works perfectly well.
Thanks again for your help, much appreciated
EDIT : that working install of Ubuntu was flashed on the EMMC, replacing the original Android version
