So my friend has a Dell Latitude e6400 Celeron 2, he go a display port to HDMI, but the issue is actually on windows choosing to connect to it, when I try fn + f8, nothing happens same with windows key + p nothing happens so I'm lost
 
From what I see about that model, there is no Display Port on it. What are you using to connect, what cables/adapters and do what? Need some background on the issue, has it worked before? Have you checked to make sure the drivers for the video card are installed from the Dell support site?
