I've had my Duo for three years and has worked flawlessly. I use the CMS with Chromapure to calibrate my 95ES projector. I recently upgraded the firmware to 2.4.1. Since that upgrade I have had some issues with frame dropping from streamed sources (Roku 3, Oppo 93, Amazon Fire). Nothing else has changed on my system. Is this just coincidence, or is it possible that the Duo FW upgrade could be the issue ? I thought I would check before here before downgrading.
