So I use a laptop and I am trying to connect a second monitor via HDMI and when I plug it in, it goes into sleep mode and I've tried going in display settings but changing stuff there doesn't seem to make a difference, any way to fix this?

    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:

    1. Press the Windows logo key + I to open the Settings app.
    2. From Settings, select System > Power & sleep, then select Additional power settings.
    3. 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.

    Hello, I tried a different HDMI cord and it didn’t make a difference, also currently I do not have another PC to test the monitor on, and changing to default settings didn’t seem to work either.

    We appreciate the information you have provided. Since the problem does not occur with a different cable, we could deduce that the issue may be with the settings of Windows 10 or with your monitor. May we know if the monitor is detected in the Display settings from the Settings app? If yes, is the settings under Multiple displays from that page set to Extend these displays? If not, kindly do so and see if the second monitor works as expected.

    We look forward to your prompt response.
