I have a refurbished T420 running Windows 10 Pro 64-Bit. When connecting a projector via the "Display Port" using an HDMI adapter, I cannot duplicate the display. It allows to extend the display but I like to have the image on my PC too and it doesn't do that. Also, when extended it doesn't allow me to run operations on the projection screen.
I have read aa few tips on reseting the video portion of the BIOS and I have checked, it is set on the NVDIA driver, the computer also has the Intel video driver. I am using MS PowerPoint 2010.
This is very frustrating any help appreciated.
