    Thunderbolt 3 capabilities on G752VY-DH72 for multiple monitors

    I am having trouble connecting more than one monitor via thunderbolt 3 hubs. I have no problem connecting a monitor to my HDMI, MiniDP and USB-C ports on my laptop, but when i try and connect one of the thunderbolt 3 docks I can only use one display that connected to it.

    Here are the 2 thunderbolt 3 docks i have
    Startech TB3DK2DPW
    OWC OWCTB3DK13PSG

    I have read their manuals and covered all the basics.
    - Trying different adapters and cables
    - Different thunderbolt software and firmware versions (currently on 17.2.71)
    - Different monitors
    - Daisy chaining 2 hubs
    - and much more

    I originally tested everything on the Thunderbolt 3 package from the Asus website. when that didnt work i used the one from intel. Here is my current setup

    I know the cables work because if i test them one at a time it works. So if I have one of my docks connected to my laptop via USB-C cable and I connect one monitor to the USB-C port it displays fine. When i try and connect the 2nd monitor to the DisplayPort nothing happens. But, when i disconnect the USB-C monitor cable the monitor connected via DP works.

    The only likely reason for this issue that I have found is thunderbolt capabilities. According to the video below by StarTech, they say your hardware may not have all thunderbolt 3 capabilities enabled.

    I am only trying to connect 1080p monitors and in that video one of the capabilities shows 2 4K monitors. So that makes me think something else is wrong.

    Both my OWC and Startech hubs have the same issue.

    I even tried daisy chaining the 2 hubs and I am able to run one monitor off of each hub. But when I try and connect that 2nd monitor to either hub it will not work.

    Does anyone have any idea what else I can try?
    Every other port works on the hub. Even connecting this USB to HDMI adapter to my hub.

    I am experiencing the same issue right now, with startech. I think we are limited on this to use hdmi, thunderbolt and mini dp and have 3 monitor that way.

    nevermind: Got the ASUS support reply today. The G752VS is not capable of outputting dual displays via the Thunderbolt 3 interface. If you wish to utilize the GTX 1070's four display output capability you are limited to using the laptop display as one of them, and only three external displays.
