Display on extended Monitor did not work

Hi,
First, thanks for to forum, this is very helpful to understand some topics.

I would like also to highlight that I am more electrical engineers, I know little bit SW but not an expert.

Here you find my problem and I hope I will get some help and technical details.

my hardware configuration is:
1- Desktop PC with Intel 9th generation configuration (Apollo lake , intel Graphics 505)
2- Monitor#1 connected DP to VGA ( VGA length cable 2m)
3- Monitor #2 connected DP to VGA ( VGA length cable 10m)

My Software configuration:
1- Windows 10 (ver 1607) and Intel Graphics driver version 23.20.16.4982.

recently I move to a new windows version Windows 10(ver 1809) and Graphics driver 30.0.101.1069

And from this update the problem started with:
- Monitor#2 is always not recognized, always as Non- PnP, in the previous version I was able to get the signature name of the monitor, not now.

- 1 boot out 4, I get my Monitor#2 in extended mode where previously I configure on duplicate mode, not a good resolution, or black screen.

- I also face issue where I cannot find my good resolution 1980x1080, not available at all.

I start checking in Forums and find some literature about EDID and INF file, drivers.

I have the feeling that I am in the good forum with some top experts, I am not looking for only solution but some technical explanation also.

I really appreciate your help.
