Laptop will not connect to monitors

Question

Laptop will not connect to monitors

Anonymous

My laptop no longer recognizes either of my monitors. It was connecting to them yesterday and now today I can't get either one to connect. Here's what I've done:

Unplugged both cables from the monitor and the power source
Ensured the monitor settings are correct (HDMI & DP)
Unplugged the docking station
Ran SupportAssist

None of this is working. I don't have any additional cables to try.

Should I start with replacing cables? Any help will be appreciated.

Thank you!

Hello, my name is Jan and I'm happy to help you today. I'm sorry you're having this problem with your monitors. Ensure that the HDMI/Display cables are attached properly, then press the Windows key + P and select Extend. If that didn't work, here are a few things you can try.

Power cycle/reset your computer.

Press the power button for 10 seconds to turn off

then unplug your AC adapter for 30 seconds

then plug in your adapter.

then start your device.

Press Windows Key + X

select Device Manager.

Expand the Display Adapter

select the graphics driver

Try to disable and enable the driver

then connect and extend to your monitor again.

Press Windows Key + X

select Device Manager.

Expand the graphics card

then right-click on your graphics card

then uninstall.

Check the box "delete the driver software for this device"

Then click on uninstall.

restart your computer.

Then open Windows Update and click Check for Updates.

It should download the latest compatible graphics driver and install it.

Download the latest driver from the Laptop manufacturer's support website and install it. Also, try the old driver if the latest driver does not work.

If you have Nvidia or AMD graphics, select the custom install and

Perform a clean install option.

Try to test or use the HDMI/DP Cable and monitors in another computer to check if the cable is working properly.

Hi Jan!

I tried all of these steps, and they did not work. I'm currently waiting for another cable, and when that comes, I'll switch them all out to see if that helps. The driver was up-to-date.

If switching out the cables works, I'll let you know.

Thank you,

Jill
