LCD Monitor blinks then goes white

Microsoft Windows 10 (64-bit)

Within the past week, when I turn my laptop on, the LCD monitor blinks then turns white. I can unplug the HDMI cable, plug it back it, and it works fine. The laptop screen also is fine and does not blink or turn white. I also changed cables, updated the driver (no update available, current), and reset the graphics card.

Welcome to HP Community

 

I have gone through your Post and would like to help

 

Any chance have you tried the monitor with a different Notebook?

 

I suggest you download and run the HP Support Assistant from this Link: https://www8.hp.com/us/en/campaigns/hpsupportassistant/hpsupport.html?jumpid=va_r602_us/en/any/psg/p...

 

HPSA will automatically search for all the latest drivers for your Notebook

 

  1. Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.

    Click Updates in the My notebook pane

  2. Click Check for updates and messages to scan for new updates.

     Updates list in HP Support Center

  3. Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.

  4. Click the update name for a description, version number, and file size.

  5. Select the box next to any updates you want to install, and then click Download and install.

Also ensure Windows is up to date.

 

Select the Start  button, and then go to Settings  > Update & security  > Windows Update , and select Check for updates. If Windows Update says your device is up to date, you have all the updates that are currently available

 

Keep me posted how it goes

 

Thank you and have a wonderful day 😊

Yes, I had already tried the update. Interestingly, I removed my password requirement from sleep and it solved the issue, for some reason.
