Got VGA no signal (HDMI no signal) error after last Windows 10 Insider Preview update

As what SergeiMerchenko mentioned, though your hardware is not outdated, you may be facing compatibility issues on your monitor and computer. The graphics card that you have in your computer may no longer be compatible with your
Windows 10 Operating System. We suggest that you consult with the computer manufacturer and see what options you have in getting the graphics card with your new
Windows 10 OS.

Regards.

Hi,





Since you are having challenges with your computer displaying No Signal after installing the latest update for
build: 14955, let us go ahead and try to boot your computer to
Safe Mode with Networking.

This way, only the basic files and drivers necessary to run Windows are started and we can access the Internet to troubleshoot any issues existing on your graphics card driver. Click on the link below to know how you can perform this step:

Let us know how it goes.

 

Hi there MariusPetran.

I would probably start by checking if you have the latest graphics card driver by searching your model number on your PC's manufactures website (e.g Toshiba, Acer etc...). Then go to support, driver download. Select OS as Windows 10 Pro, with either 32-bit or 64-bit (whichever one you have).

How about initally using your VGA connection to boot and login to Windows, then switch to HDMI (making sure VGA cable is fully unplugged and HDMI cable is plugged in at both ends).

Could you also provide the manufacture and model number of your PC and new Monitor? It could be just a case of configuring the PC or monitor in a certain way to establish a connection.

 

Thanks for response,i've tried to uninstall the drivers and reinstall them,but didn't work,so today i did a clean install with only HDMI cable plugged in,and it worked *Smile.
I still didn't know what was the problem,why windows refused to give HDMI signal to my monitor ? it was like the windows knows only VGA Mode,i think was a bug,maybe i will report it to Microsoft/Nvidia.
In any case,to people who will have the same problem,a clean install with HDMI cable connected during the instalation,will resolve the issue.

 

Nice work! *Smile

Yes that is very strange. It could just be the way windows installed the monitor via HDMI incorrectly but a clean install sounds like the way to go. For those who do indeed have the same problem, do try to fix the issue before doing a clean install. Make sure to backup everything and refer to the clean install tutorial.
