Using 2nd Monitor with Laptop and Goes Into Sleep Mode

Hi Charlie,

If your second monitor goes in to Sleep mode after connecting it to your laptop, it could be that some settings of the Power Options in Windows 10 are incorrectly configured. We recommend that you restore all power settings to default and see if the second
monitor still goes to Sleep after connecting it. Here's how to restore the power settings to default:

• Press the Windows logo key + I to open the
  Settings app.
• From Settings, select System > Power & sleep, then select
  Additional power settings.
• From the Power Options dialog box, select Choose when to turn off the display, then select
  Restore default settings for this plan.

After setting it to default, observe if the issue persists. If it does, kindly connect the second monitor to another computer and see the problem is observed. Also, kindly use a different HDMI cable to rule out the possibility of a faulty cable.

We look forward to an update from you.
