I can’t connect to an external monitor using a usb c to DP adapter. It’s the 3rd adapter that I bought from Amazon and none of them seem to work. What is really strange is that the Usb C to HDMI adapter works perfectly allowing me to run the monutor at 175 hz. I read that some other models (mine is rz09-0329) had a bios update to fix this issue. I currently have the latest bios ver 1.06. Did someone also experience the same problem? 

Thanks
