Have a need for a field monitor for videography. Besides for the Mavic, one of the reasons why I bought the CrystalSky Ultra is to possibly use it as a field monitor.

Before I invest in a filed monitor - DJI please let us know if are you still planing to release the dongle that allows for CS to accept HDMI inputs? ETA?

Are there any third party software/hardware solutions to use CS as an HDMI monitor?

You're asking DJI a question about releasing anything promised and are expecting a actual meaningful answer??? good luck..

DJI is the worst company in the world when it come to CUSTOMER care... All promises until you spend the money, than nothing but contempt with "approved" cut and paste answers.
Still.. I wish you good luck.
