I have an old laptop (4 year old) on Windows 10. It works fine but does not detect a second screen. Windows is up to date and I am sure the second screen/cables etc work as it works with a different laptop. I even uninstalled and reinstalled the graphic device but have no luck. The second screen is about 3 years old. The connection should be plug and play but whatever I tried, there was no input to the second screen. I have other laptops which are also a few years old, they do not connect to/detect the second screen either. I have tried all solutions suggested in Google search. The cables I used were type c/ type c, usb/type c and hdmi/type c. Please help.
