I&#x27;m using Duet too.<p>It&#x27;s a <i>little</i> quirky - the most annoying bugs are unpredictable disconnections and occasionally screen freezes, this seems to happen mostly when my macbook locks and reopens. But these things don&#x27;t happen regularly enough that it causes a major problem for me. It&#x27;s a bit annoying but I can deal with it.<p>One thing to note for anyone considering it - it performs really well at displaying text. Things like tailing logs, or displaying docs. However, anything involving typing and using the mouse is a bit painful compared to your main screen because the lag can be tedious and uncomfortable for fast interactions. In addition, I keep the refresh rate at 30Hz when on battery to save power, which compounds this issue.
