Had Windows 10 reinstalled on Lenovo computer- now HP w1907 monitor won't work. Help???

Monitor worked before Windows 10 was reinstalled on my laptop. Now the monitor doesn't work- says I need to adjust the resolution numbers, which I did, but that did not work. Any suggestions?  Connected with HDMI cable to laptop

@luckotheirish If Windows 10 can't detect the second monitor, before modifying any settings (and assuming it's connected to a power source), you should try these troubleshooting steps:

• Restart your computer to re-establish the connection.
• Using the built-in controls on your monitor, make sure the correct input is selected.
• Check the cable connection between the monitor and the graphics card.
• Disconnect the cable from both ends, wait a few seconds, and reconnect it again.
• Use a different cable, as the issue could be the pins in the connector or a bad cable. Also, if you're connecting a new display, make sure you're not using the incorrect cable.
• If the monitor and graphics card include multiple ports, try switching ports.
• Connect the monitor to another computer to determine if it's not a problem with the monitor.
• Connect another working monitor to determine if it's not an issue with the graphics card.

That said, A major reason for Windows 10 won’t detect HDMI monitor is graphics driver issue. You can go to “Device Manager” to check the status of the display drive and update it.

• Type “control panel” in search box and click it to open. Choose “Device Manager” from the computer settings list.
• Expand the category “Display adapters” and right click the monitor you want to update drivers for, select “Update Driver Software”.
• Then click “Browse my computer for driver software” to go on.
• Click “Browse” and navigate to the location where you save the driver files, follow the on-screen instructions to finish the process.
