We have an HP Pavillion DV7-4080 US Entertainment Notebook, Windows 7 OS. We have previously used an external monitor with the laptop to have 2 screens to work from.
Now, the laptop is not displaying a picture on the external monitor. The external monitor is detected as if it has a signal, just no picture.
We have done the following:
Tested the external monitor on another computer, the monitor is alright.
Tested 3 different external monitors that are known to be working.
Worked in the Display Settings to choose "Extended Display".
Updated video drivers.
Tried both VGA and HDMI ports.
Any ideas on what we can try next?
