Display port to HDMI does not produce any audio when connected to TV

2018-01-16, 20:10 PM


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.
