Thanks again for the cable, and also for the compatibility between these units! It is a huge deal for me because I have Surface Pro (w/ UD-3900) at work and Dell Venue 8 Pro (w/ UD-PRO8) at home. Unfortunately, my Venue 8 Pro has been experiencing a major issue with its motherboard and LSD panel, and send back to Dell for several times now. I was wondering what should I do with UD-PRO8, but now I know that Surface Pro works, I can bring Surface Pro to home!
Having an access to a larger screen helps me a lot, especially with Surface Pro’s badly designed kickstand. I know that you need only a display adapter for Surface Pro to connect to an external display. However, for some reason, mine limits itself to a lower resolution than it is capable of when I connect to any external screen. It works fine for presentations, but for actual work, it is very annoying. I have called Microsoft, and only thing they can recommend is a complete restore, which I do not want to do… Plus, Surface Pro only has one USB port, and I am getting sick of removing my USB mouth received whenever I have to connect other devices. Thus, UD-3900 and UD-PRO8 have been lifesavers for me!
