Duet Display on the App Store - - Download duet display for windows free Looking for: Duet Display Download ( Latest). Click here to DOWNLOAD - One moment, please First time i write a review on App Store because i was amazed by the Duet support team. The iPhone screen is quite small to be used as 2nd monitor so i passed on that. As a normal human being, i tried FAQs, Google to find answers but there is no working solution. So as a last resort i turned to support, got an automatic reply email and went to bed. The day after that, i found out that they replied literally 5 minutes after that with a few questions and a solution. They kept providing me solutions after solutions, we exchanged emails for a week trying everything, they rotate 3 people in to help on my issue. The team is very polite, specifically pointed out every step along the way, never loose patient and always reply within the hour. After all it was a dumb mistake on my part, so everything is working norm
