At first, sorry for my bad english.
When my box is booting and the receiver or tv is in standby or off, the video resolution is wrong, and the tv switch from “Just Scan” (LG TV) to 16:9.
When the tv or the receiver is on and i restart the box, i can use Just Scan at the tv and everything is fine.
How can i solve the problem?
I forgot, Box have 3GB DDR4 Ram and 32GB Rom.
