Hi guys, I am pretty new here. Recently purchased a studio display with firmware 17. Currently I have this setup to use one studio display for both my mbp and PC. Don't know if anyone else is experiencing the same issue as I am having now:

First the studio display works perfectly with my mbp and ipad without an issue. However it truly causes me a headache when trying to connect with PC. I purchased this cable based on some feedback I saw in this forum and reddit and the display works as a charm. After installing the correct bootcamp following justins tutorial here, I can get all the speaker, mic, and camera working, confirmed. And I am able to control the brightness through the bootcamp app. Though the device manager still recognize it as a "Generic PnP Monitor".

However, somehow I cannot get the display to turn on when I start the PC every time if I do not unplug/replug either the USB or the thunderbolt side on the cable. It won't automatically turn on when the PC turns on, and it will never get into the BIOS img even I unplug and replug fast enough. The USB side of the cable is a USB2 with separate power to the cable itself. First I thought maybe it's the IO issue where USB does not have power when in sleep or shut down, but I can wake the PC using mouse or keyboard which means there should be power. Also the ERF in BIOS is in off stage (USB power definitely > 1W). The issue is similar to what's reported here but I failed to find a solution.

I am currently out of ideas and right now I am simply using a spare trash HDMI monitor to work on any BIOS stuff. It would be greatly appreciate if anyone can enlighten me.
