I have a Macbook PRO Retina early 2015. I have installed bootcamp 6 and windows 10. I have an issue with the Iris 6100 driver (currently 220.127.116.11.4240) which is installed (with error 43). The consequence is that I cannot change the screen resolution (only 2560x1600 is possible) and therefore I cannot drive external projectors or monitors which I often use. This issue was present also in windows 8.1 (but not in windows 8) before updating to windows 10. I have tried to install the latest intel drivers for windows 10 but it did not work. Any idea on what to try? By the way, also the Bluetooth USB Host controller driver is not working. This was ok in Windows 8.1.
Thank you for your inquiry. For Microsoft Windows 10 this is the web site to download https://downloadcenter.intel.com/product/86209/Intel-Iris-Graphics-6100-for-5th-Generation-Intel-Core-Processors
But for best support on the installation and compatibility will be best to contact Mac Support for
