This still isn't working. I'd really like to know if my monitors are supported. They are 24" apple cinema, and 27" thunderbolt.
Windows should be compatible with your monitors, however, the Surface hardware itself is not.
Now, since you are using an active adapter which is the Surface Dock, the monitors could work since it's not included in the list of known monitors that does not work with the Surface Dock. We suggest that you follow the steps on this
article.
If after following the steps and your monitors are still not working with your Surface, please contact our Surface Answer Desk team for further assistance.
