Cannot Duplicate Display / Screen

I am a Surgeon. During years I have been using 2 displays duplicating the screens to show details of the operations to my patients. Recently, after a Windows 10 update I cannot any longer duplicate the Displays / Screens.

I have searched online for the solutions and everywhere it says about drivers. I have update all drivers, I have used the intel updating driver tool, I have followed all the steps suggested by Microsoft, and I cannot duplicate the displays / screens yet.

I will appreciate a Step by Step guided solution. 2 displays / screens are essential for my job as a Surgeon.

Thanks.

Display Default- How do I change my display default to Duplicate these displays?

Hi Gina,

Making sure that the projector and monitor are properly connected is the first step that we need to do in resolving the issue. Once verified that they are properly connected, we recommend
updating your device drivers by going to the manufacturer's website to download the its latest driver, and finally, let's follow this steps to duplicate the display:

• Press and hold Windows key +
  P.
• Choose the option whether to use the PC screen only,
  Duplicate, Extend, second screen
  only.

Let us know if you need further help.
