Sorry about the doublepost! But I'm doing that to share some news!
I just reinstalled Windows 10 from zero, even deleted personal files as I transferred them to an external disk drive.
After reinstall windows, I rejected to connect it to Wifi and went to:
- Control Panel
- System
- Advanced system configuration -> Hardware -> Device install configuration -> NO (to disable automatic driver updates).
Then I connected the laptop to Wifi, and what a surprise! Windows 10 COMPLETELY IGNORED my wish to Not Install drivers automatically!
However, it installed both Microsofts Intel + Nvidia drivers (outdated versions ya know) plus the sound driver, and surprisingly
now I can use MZ on Both screens!!
So hey Killuki, what's the isue then?
Here's the answer...
¯\_(ツ)_/¯
Sorry, but don't know.
But my guesses is that,
any newer graphic controller driver could make MZ from stop answering.
Also, I just thought that I don't have VMWare Player installed, which I use in my work to keep separated my personal computer from my working environment (so my chief can't monitorize what I do outside that virtual space (smart guy here heheh).... neither I updated DX, or installed any windows update yet.
But I remembered a thing, Valorant was anti-vmware for some reason, just due that program the videogame couldn't launch, maybe it's a driver of vmware which causes the issue? I Hope not!!
I will edit this post once I installed VMWare and any other additional program to see if I hunt that criminal which makes our hybrid-card laptops look like trash (specially when we're trying to develope our games in MZ/MV), so MZ programmers can provide a fix to kill this five-years-beast.
EDIT: No issues caused by VMWare either, I'll keep you all updated if I catch what causes MZ to stop breathing in a new reply if 72 hours have passed! (I think that was the minimal time to doublepost, respect the rules!

).
