There's no button to switch on the internal button display. Again, whenever selecting another dispay using FN+8/windows key+P I get a black screen.

I'm so sorry, I just realized I started 3 threads for the same issue. I disabled the driver for the display, currently the only image I have is from my tv connected through HDMI. My computer display no longer appears as a display.

i would go to hp and reload all the driver they will suggest for that model and the os you use, i seen they also got a diagnostic app
