So my friend has had this problem getting his dual screens working.
So far I've tried to help him, but I'm quite bad at figuring out hardware problems.
Here's the things that I've tried to get him to do:
Restart in safe mode and change the resolution (obvious)
Make sure it's all properly plugged in (again pretty obvious)
Turning on low-resolution mode.

All I want is some advice. Thank you in advance.
