How to change screen displays when there is no screen display?
My refurbished and problem free (except for new SSD) Lenovo V750 is on but showing only a black screen. I have 2 screen settings - 1 for a Dell Monitor and the other short wide one (that I hate!) for the Notebook display. How the heck do I change the screens when I can't see a screen at all? I'd like to figure this out to determine if my display card is shot or if #2 grandson just f*cked with the wrong keys! Can anyone advise? Thanks in advance.
