Solved! HP Probook 450 G2 Not Detecting HDMI Output Port

[beeforoni]

Like the title says, my laptop will not detect any HDMI activity. I was trying to setup my new HDTV with it but it won't pick it up. Tried with other HDMI-compatible screens and doesnt pick anything up.

I am running Windows 7 64-bit and have done a clean install of Windows and have had no problems with graphics or anything, all my drivers are up to date and functioning correctly except for this. I only have a single display adapter in my device manager "Intel (R) HD Graphics Family". The cable I am using I have been using for years with no issue and it works on other devices. I have reversed the ends and that has not solved the problem. Is there anything else I can do?

Ninja Edit: My Fn keys are also non-functional (but I don't know which driver would fix that) so I do not have access to any of those functions via the keyboard.

Do you know if the VGA port works?

I managed to fix it right before bed last night. I swapped to a different hdmi cable despite that one working with other devices and it worked. These things are fickle as they come. Thanks for your help.

I think your Ninja Edit contains the issue. Seems your laptop is only outputting to the internal display. Not the external one. You need to toggle that setting to use an external display.

Try installing HP Hotkey Support to see if the function keys "wake up":

I have installed it but as it turns out the Fn key for display management is just a glorified Win+P hotkey, so that's a dead-end. Any other suggestions?
