    Monitor went to sleep mode when connected to PC but light up when connected to laptop


    The day before, the PC is fine, before I went to sleep I turn off both my PC and my monitor. Later I woke up form a thunderstorm and worried about my PC, so I unplug the PC and the monitor. Next morning I re-plug all of them but monitor went sleep mode but the PC is on. I tried connect HDMI of the monitor to my laptop and the monitor light up. Can someone help me with this problem?

    :)

    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.

    Things to do once connected new G-Sync monitor

    I'm getting my G-Sync monitor today.

    I think I have to take the following steps:

    • Connect 1440p G-sync monitor with DP cable
    • Connect second 1080p 60Hz monitor by HDMI
    • Startup PC
    • Reinstall display driver
    • Restart PC (I always do that after display driver install)
    • Activate G-Sync in NV control panel (I believe also V-Sync is auto on after that?)
    • Set my 1440p monitor from 1080p to 1440p
    • Calibrate my 1440p monitor
    Also ingame, I should turn off V-Sync?
    Are there any problems running a second 60Hz 1080p monitor?

    Is there anything else I should do/know?
