    Windows 10 not detecting 2nd monitor but it did before.


    I have a new Lenovo AIO that came with Windows 10. From the start, it successfully detected a second monitor connected by HDMI. Yesterday I disconnected the second monitor in order to move to a new location. Now Windows is not detecting the second monitor. I've disconnected and re-connected the cable and re-booted but to no avail. In device manager it shows that I have the latest update for the display driver. Any ideas?

    Win key + P will bring up the projector (second monitor) options. Can you extend or duplicate displays there?

    Have you tried rebooting the computer with the second monitor disconnected. After the computer boots up with only the primary monitor connected, then connect the second monitor?

    Also, judging from this photo, it looks like you might have both HDMI out and HDMI in jacks. Are you connecting the monitor to the out jack? In the photo that would be next to the LAN connection.

    Awesome :-). I worked for a cable TV company before joining the Navy in 1988. Got a trouble call that stated "Cable out since vacuumed floor". Walking in, pulled the power knob on the TV. Nothing. Reached behind the TV and plugged the power cable back into the wall. :-). It happens.
