Trying to use Imac (2013) as a second screen.
I'm using a Dell Laptop for work and I wanted to use my Imac (2013) as a second monitor but even after plugging in the mini display adapter, nothing is happening. My Imac display preferences don't even include the "arrangement" tab.
Is it not possible to use my imac as a second screen?
