7.7 installation results in black screens

[lincoln12]

I had the same problem with a Suirface 3 Pro i5

I have attached my log from when I had 7.7 installed.
7.7 Blank screen, 7.6m2 screen worked

Also, when I uninstalled 7.7 and installed 7.6m2, my wifi stopped working properly. It would connect to the router but not connect to the internet.
I uninstalled 7.6m2 and now the internet connection worked.

So at this point I can not use my external monitor.
I have both the Diamond DS3900 and MDS3900 And it was the same with both.

I really need this to work again....

Thank you guys
