HI guys,

I'm not sure if I'm in the correct section but I'll be glad if you can help me with my problem

I just bought a mi box - the latest one, mi box 3 (literally hours new) and I was able to set it up. Upon seeing that the resolution is set to 480 (default), I have tried changing it to 720. After the attempt, it went black and says "not support".

-I have tried removing the hdmi and putting it back -Also removing the power source -Same with the hard reset.

I can't change the resolution back to 480 since I'm unable to boot the mi box and not showing anything aside from the "Not support".

Thanks in advance for the help.

UPDATE: Issue is now resolved. I hooked it up to a different tv that supports 720 and put it back to 420. Thanks for the help.
