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.

    Actually, they've recently done that, but just have not publicized it.

    https://support.microsoft.com/en-us/help/4023468/surface-troubleshoot-surface-dock-and-docking-stations?os=windows-10

    Use an HDMI, DVI, or VGS adapter is the section to look at. And I asked them a week ago to fix the link to the Microsoft branded cables but they didn't. The link is https://www.microsoft.com/en-us/store/d/surface-mini-displayport-to-hdmi-20-adapter/8qj8ss92m2tl/ch5z?activetab=pivot:techspecstab

    >I sure wish Microsoft would just state that their Dock does not support 4k monitors and you need to use an Active adapter.

    Agreed on all counts.  I read somewhere that the problem does not exist if you switch cables to the HDMI type.  I currently run from the dock (mini DP) to the monitor (full DP) and get the endless problem being discussed in this thread.   I don't have a mini DP to HDMI cable otherwise I'd try.  In any eventi think this is total BS and needs to be corrected immediately.

    Hello Erwin

    You have no clue what this discussion is about. So I would make a polite request for you to spend 30 minutes to read the complete thread before responding. Otherwise, you also have the option to not respond. You are wasting our time.

    BTW, good job! Thanks to those who figured out that the issue is only with DP firmware and not with HDMI firmware. I have ordered a mini-DP to HDMI cable and will let the group know of the results once I get to try it out on the LG Ultrawide

    Somehow, I get the feeling that people are muddying the waters and deviating from the originally reported issues at the top of this thread. The Surface Dock does not allow monitor to go to sleep peacefully. Latest firmware and software and all. I would ignore the answers from MS support staff offshore since they only add to the confusion. This issue is certainly still unresolved. But I must also state that it is not a very big deal. I turn off the monitor manually before I go to sleep every night and that works! Afterall, there were the days decades ago when you had to manually turn off the computer. I and many of my colleagues love the Surfacebook. It is the best thing that ever happened to laptops.

    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
