I've just upgraded my personal machine from HP 8560w (FullHD TN Panel) to Zbook 15 G2 UHD+ (3200 x 1800 IPS). The 8560w has been upgraded with GTX 965m MXM Type A graphic card for 1 year now and all running fine. Since I upgraded my machine I wanted to move the GTX 965m to the Zbook, since it is much better than the k2100m for the use I need (dont do any CAD or OpenGL intensive stuff). So I moved the GTX 965m to my new machine. However the laptop display would never light up. The laptop boots successfully, I can hear the Windows 10 loading sound, but screen is black. Putting bright light against it to see if its just the backlight not working due to missing drivers doesnt show any picture at all (like it did on the 8560w.
However when I connect the laptop to a docking station, then the external monitor lights up successfully and I can login, install the Nvidia modified drivers for this laptop and the GTX 965m is recognized successfully in Windows 10 Pro. As soon as I undock the laptop, its display still does not work, although correct drivers installed now. Already watched this video () and I thoroughly checked BIOS, but my model/variation Zbook does not appear to have Hybrid graphics option in it (I later found info on various forums that Nvidia Optimus does not work on HP DreamColor displays). Although my display is not DreamColor, I assume it is the UHD+ resolution that is most likely the reason for Optimus not being supported. Anyway, although Optimus would have been nice for battery saving, I dont care for it, I just want to get the laptop display working with the GTX 965m graphics card.
I also installed the k2100m on the 8560w laptop and the result is even worse - no output neither on laptop display, nor on external monitor through docking station. So with all of that said, I would assume it is eDP/LVDS issue. Question is, can I make the GTX 965m card output eDP signal to the laptop display? Flashing a vbios maybe? If I understand correctly info I came upon, all graphic cards prior Pascal support both eDP and LVDS, but its not both simultaneously, only one is enabled and working.
I would appreciate any help I could get on this, as I was going to primary use this machine as laptop and only occasionally dock it.
P.S. If you're going to suggest I get 1050Ti or P1000 graphic cards, please provide links where I can buy them. I would prefer to stick to the 965m for now, if above issue can be fixed!
Thanks in advance for any help!
