For other side, If i change resolution to 1920x1080i, kodi show the letters with lines and it blink. This problem occur in the gt king and the khadas.

With stable coreelec 9.0.3 in ki pro box, it work correctly.

How update the bootloader?

6

Hello, could anyone say me something about these problems? it is normal?

And how can i update the bootloader?

Why are you using 1080i? There’s no point, use 1080p instead.
I can’t help you with the uboot update, though.

I am testing all resolutions. If i use the box as sat client, if i use 1080p i get judder and with 1080i it work perfect.
And this resolution work well with s905 box.

Why? i do not understand, what i fix with uboot update?, could you explain it to me?

Thanks
