Surface Dock keeps waking up external monitor

Anonymous

My monitor (LG 29UM68) is connected to Surface Dock -> SP4, via direct miniDisplayPort.

It keeps entering sleep mode and waking up repeatedly, even though my SP4 is asleep. This does not happen when I connect the monitor to SP4 directly.

Another issue is that if I set to PC Screen Only, after few seconds, it will automatically switch back to external monitor only. Again, this does not happen if I connect monitor to SP4 directly.

These 2 issues only arise if I use Surface Dock.

I have gone through all the steps here (https://www.microsoft.com/surface/en-sg/support/hardware-and-drivers/troubleshoot-docking-station-surface-dock) successfully, but issue persist.

Please help.

    Hi Erwin,

    Issue exist since day 1 of owning a surface dock.

    There is no error message. As long as I sleep/hibernate the SP4 with the dock plugged in, the monitor will keep waking itself up. If I shutdown the SP4, the monitor goes into power saving successfully.

    Hi Edmund.

    Thanks for reaching out. Can you give us more info about your concern? Were you able to use Surface Docking Station without experiencing this issue before? When did this issue start? Did you recently install new software or updates?  Did you receive any error messages?

    Regards,

    Erwin
