Hi, I want to add a 3rd screen to my set-up, I have a thinkpad laptop and a screen plugged in to the HDMI poirt, but I want to add another screen, what cable do I need to do this please?
I think I once had a cable that attached two screens and then that was attached to my laptop so I want to do that again. That was all set up by IT at work for me though and now I work at home so have to do it myself.
Thank you!
