I have an old Sony TV, and I have an issue with my new Bqeel K12 TV box... https://www.amazon.fr/gp/product/B01M9IZZFD
It seems there is an issue with old Phillips and Sony TVs, randomly I have a green screen... I found there is a fix with a firmware update to enable RGB output. This fix must be given by the manufacturer it seems...
I currently don't have this option in Settings -> Display
Is there a way to enable/force it with root ? It is only in kernel ?
My box is rooted, but no custom recovery currently.
I don't know if Bqeel is just a rebrand of another Box or if I must wait/hope for a new firmware with fix from them...
Thank you for your help
