Hello!

I was about to test Lucidlogix Virtu MVP on windows 8.1. After installing Virtu MVP windows didn't want to boot up anymore so i had to go into Safe Mode to uninstall Virtu MVP, after that windows booted up successfully. So i gave it another try, same thing happened but after fixing it then second screen stayed black and at display settings it didn't detect second monitor at all. So i did some registry checking and saw there were some ActiveX/COM igfxsrvc.exe issues at system32 folder, checked into that, that program did not even exists. So i did little research and turns out it's caused by intel drivers. Uninstalled intel drivers and error disappeared, re-installed them and error came back, re-installed again after registry fix, error was gone but second screen still won't be detected.

So i went into BIOS disabled d-gfx and ran as only i-gfx and second monitor worked fine and used Intel's drivers automatically as well instead of AMD ones as i have on-board vga for second screen and dvi for d-gfx(AMD card), it used to work fine like that but not anymore. What is going on :S?

I always had from BIOS init display = AUTO and Internal GFX = enabled. Always worked before! Now i tried something, set init display = igfx and suddenly it detects both monitors! Only that amd one is marked as 2 and on board one is marked as 1 from display settings of windows, had to set display that's connected to the amd card to main one.

But still i want to know now, how the hell did this happen?! It did not work like that before and now with init display = AUTO doesn't work anymore because second display stays undetected and suddenly with igfx it works fine and i can use d-gfx as well with main monitor. So weird to me as init display = igfx means it will be set to use ONLY onboard gfx as you can use there PCI aswell for just d-gfx...
