I have a Windows 10 x64 machine with 2 x 4K monitors and an NVIDIA Titan X GPU.
The problem started when I booted up the machine today and noticed that the resolution on monitor 2 was wrong (everything was too large).
I went into Settings and it indicated that the maximum resolution of monitor 2 was 1920 x 780 instead of the proper 3140 x 2160 of the other monitor.
I decided it might be a graphics driver issue so I went into the Control Panel and uninstalled the NVIDIA driver and rebooted. At this point, both monitors displayed at the correct resolution using the default Windows driver.
I then tried to reinstall the NVIDIA driver but it seemed to take a very long time and eventually I did a “hard boot”.
Now, when I boot the machine, the usual process of the Windows logo and the spinning dots appears on the right monitor but then when it would normally switch over to the left monitor and allow me to log in, the left monitor remains black and the booting animation on the right monitor freezes (whereas normally this monitor would go black until I had logged in).
It seems that the OS is working as I can hear a couple of normal notifications that happen as the OS boots but I am unable to log in or do anything as the left monitor remains black.
That’s where things are now. It looks like the graphics driver did not install correctly and that’s causing the problem.
I’ve tried various recovery options like booting from my original Windows DVD but I can only get to the option of keeping my files but losing all applications and settings (which is not acceptable).
Reinstalling Windows and all apps would take at lest one week and I simply don’t have that much time.
Given that it seems to be just a problem with the graphics driver, can anyone suggest a way to fix things with the least impact and downtime?
