Resolve Windows 10 related issues for your HP computers or printers by HP Windows 10 Support Center
i was multiple displays and now that opion is no long available . what can i do to get it back.
Anywhere on your computer's "wallpaper", click with the second (usually the one on the right) mouse-button, and choose "Screen Resolution".
Does it show that you have two monitors?
Click 'Identify' -- a big '1' or '2' will display on your monitor.
Is it set to "clone" the Windows display onto both of the monitors?
Is it set to "extend my display onto this monitor" ?
only one display is shown and number 2 said does not detected
When you open the Windows "Device Manager", does it look like:
1. you need to "click" to "expand" the 'Display Adapters' branch of this "tree".
2. if it shows "generic device", you need to download/install the specific device-driver for your video-card, to enable dual-monitor support.
3. it should show two devices (this computer does not have a second display, so this picture only shows one).
Point #2 is probably the most important.
If you have done this point, then #3 will show the multi-monitor capability.
