I just switched to a MacBook Pro Retina, and I've found that using a 1080p monitor (connected via HDMI) has been an eye sore. Going back and forth from the Retina display to 1080 is really annoying. Stupid question, but if you use Duet Display and an iPad Pro as the secondary monitor, will you get the same Retina resolution on the iPad Pro as you do on the Macbook? I've been on the fence as to get an iPad Pro or not, but if I can also use it as a secondary monitor (with Retina quality) this I will definitely be getting one.
