Recently bought the Mi 4A Pro 43" Full HD LED TV as a 2nd TV.
I so happen to check the resolution of the content playing on Hotstar. While the video content showed 1080p feed. The screen resolution remained at 720p!
I even downloaded resolution app to check called "Wear ScreenInfo" on the Mi playstore which confirmed the 720p screen!
Mi helpline, chats etc have no answer.
Shocking how Mi can do this! Pl check your own TVs..
