There is no HD options on the DJI Goggles for the Spark. 
DJI Goggles are 1920x1080 per eye BUT we can only get 720p when connected to the DJI Spark.
At 720p the viewing experience is less than optimal. Everything looks a bit blurry.
I can get a better resolution display using my old Headplay connected to my Nvidia Shield tablet.
Why should we pay big bucks if we cannot get full HD viewing mode?
Also, no focusing ring is another big issue for guy like me.
Hey DJI are you working on the HD options for the Spark?
