Windows 10 - Your PC can't project to another screen

[Michael-Kunz]

Operating System: Windows 10 64bit

I upgraded from Windows 8.1

My second monitor connected via HDMI worked fine with Windows 8.1

Now I get a message -  Your PC can't project to another screen

I have downloaded and installed the Windows 10 driver for the Nvidia GeForce GT 740M but it has made no difference.

Please I need some help

Thank you

Michael

Make sure everything is plugged in right and restart both computers and make sure the usb cables are recognized in the computers

After much frustration yesterday and last night, this morning it just worked. I am not sure why.

Simply bring up your device manager: You can connect to the device manager by typing it on the search bar. On the device manager select the Display Adapters and Update the HD graphics family. NB: You need internet connection to fix this. Enjoy

When I try to update the driver for my HP HD 4000 Graphics card I get a message that says "the best driver software for your device is already installed."

And yet.................it won't open/provide the ability to add a second screen.

Adeola:  I've tried your solution with no luck.  The initial message I get says "Windows has stopped this device because it has reported problems. (Code 43)".  Then when I update it tell me everything is okay, but nothing has changed.  Second monitor displays "No Signal".

The frustrating thing is that I was using two monitors for months with no problems, then all of a sudden this happens.
