Hi,

Before we assist you let us know few details,

As initial troubleshooting steps I suggest you to install the latest windows 10 updates, please follow the steps to install all the windows updates.

If you want to check for the update now, select the Start button, then select

Night Light Setting and Third Monitor.

Hi Reagan,

We would like to ask you some questions in order assist you properly:

• Did Night light work previously on all three monitors?
• Have you made any recent changes to your PC?
• Are you getting an error message on the third monitor regarding Night light?
• Is the third monitor being detected by your PC?
• What troubleshooting steps have you performed so far?

While waiting for your response, we suggest that you try to connect your third monitor to what you are using on the 2 working monitors to see if it is only a loose connection issue.

Regards.

 

Lost Power, now PC won't boot. Powers on and clicks.

I had tried both of those steps. Neither worked. I have a replacement power supply on order. Should be here on Monday. Thanks for the suggestions.
