Laptop monitor disappeared after graphics software update

[Lerey]

I just installed Ge Force Game Ready Driver. Release date 5/23/16. Version 368.22. I have a Lenovo Y510P laptop with dual graphics cards.

Since installing my laptop monitor is not recognized as a device or a display option. Other monitors work fine when I plug in to VGA, etc. but I can't dual monitor anymore. Any ideas what would have caused this and how to fix it?

Best,
Lerey

Laptop displays are difficult to diagnose.
Since you only encountered the problem after updating the drivers, try clean installing and revert back to an older driver version. You can find all your older version under C:\NVIDIA. http/www.tomshardware.com/faq/id-2767677/clean-graphics-driver-install-windows.html
If that doesn't work, we'll move on to other steps.

Thank you! I will try this as soon as I get home from work today! Will repost with results.

Thank you! That solved it perfectly!

Huh. It broke again... It was working for about a day, but now the laptop monitor disappeared again. Any other ideas?

That worked and fixed it for about a day, but then it broke again. Any other ideas? Or way to implement it better?

Do you see the BIOS post on your internal display?

I see the "Lenovo" on it during startup as the first thing. But after that it goes dark.

Have you tried repositioning the screen to see if it shows at a different angle? It could be a loose cable.
Another thing to try is uninstalling the drivers completely, remove the old driver installers, then letting windows update automatically install the driver or choosing"update driver" from device manager. This isn't ideal, but useful for troubleshooting at minimum.

Thank you! That worked! It is showing a driver from July 2015 now but it works fine.

(uninstalling the drivers is what worked)

Glad to hear it's working, but this is a problem that may come back with a vengeance later. I had a laptop that did this same thing, until it just quit booting windows altogether, but for some reason Linux still works...
