[Bootcamp Win10] USB-C to Displayport connected Display not working in 2017 MBP 13" TB
I've read about this issue on several forums but haven't found a solution that works.
The situation:
I have bootcamp (Windows 10) on my MBP 13" 2017 with Touch-bar and it works great.
However, when I'm in bootcamp windows won't detect my 27" ILYAMA 4K display (PL2792UH) which is connected with a USB-C to DisplayPort cable. In normal MacOS mode, the display works perfectly.
When I restart and select the bootcamp partition, it briefly mirrors the windows update or log-in screen but then, after logging in or while logging in, it states 'no signal detected'.
The display has a USB-hub which needs a separate connected USB-cable to work. From the display this hub is connected through the USB-cable to an Apple HDMI-dongle to my MBP. This Apple dongle also connects the battery adapter to my MBP. I've got a USB-to-lightning cable, which connects my Apple keyboard to the display's USB-hub. This keyboard works, so the windows DOES recognise the display's USB-hub.
Note: the displayport>usb-c cable is NOT connected to the dongle, as it seems that my normal macos can't detect the display then either. So the display is connected directly, without a dongle, to my mac.
The MBP specs:
- MacBook Pro (13-inch, 2017, Four Thunderbolt 3 Ports)
- Videocard: Intel Iris Plus Graphics 650 1536 MB
- Processor: 3,5 GHz Dual-Core Intel Core i7
- 16 GB 2133 MHz LPDDR3
What I've tried:
- Usual ol' restart
- Cold restart: aka turn mac/windows completely off - wait until caches clear- turn on windows immediately without first starting MacOS
- Updating windows
- Updating bootcamp
- Updating the drivers through the device manager
- Reconnecting the display: doesn't do anything when windows is logged in.
- I've read about disabling some sort of power saving mode in regards to the usb-ports in the network adapters portion of the device manager, but can't anything resembling that.
- When I look through the device manager, at 'Univeral Serial Bus controllers' there is one 'Unknown USB Device (Port reset failed)'. Though this is not always the case, so I'm not sure it's connected. Just now I did a cold reboot and there's no failed ports right now.
So, how do I get this external display working in bootcamp?
