The purpose of this post is to report and issue and describe a partial/sort-of work-around, in part in the hope that it can help others who see similar symptoms, also in the hope that a Microsoft Engineer might see this and be motivated to dig a little deeper.

Windows 10 does not recognise second monitor

Hi Raffaele,

For us to sort out this problem with your dual monitors, we'd like to gather more information about what happened so we can address the issue appropriately. Below are a few questions we'd like to ask:

• Does the monitor on the laptop work if you disconnect the other monitor?
• Is the second monitor connected to the laptop using a DVI, HDMI, or DisplayPort cable?

While waiting for your feedback, we suggest that you disconnect the second monitor from the laptop and check if its own monitor is working. If not, restart the laptop and check again.

Update us with the result.

Regards.

 

Grpahics card and monitor not recognised by Windows 10

My ACER G277Hl and my Graphics card GE Force 210 are not recognised by Windows 10.

I have tried to use the manufacturer disk to add the Graphics card driver but get the message that it cannot be installed because the card is not recognised

I have tried downloading the manufacturer driver for the monitor with the same result.

In device manager there is no graphics device listed under others when I use view to see hidden files.

Do I need to reinstall windows 10 and loose all my applications?

Even if I take this drastic step will it fix the problem?

I am inclined to reinstall Windows 7
