Mixed impressions X5

I was looking for a device to play hevc x265/10 bit files.
Got x5 and i am tented to look for something else.
Problems i discovered:
1. Box keeps reverting to 720/60Hz after every boot.
2. I i set auto refresh framerate to on, all my videos stutter, skip frame.
3. All my 1080/10bit files plays choppy/skipped frame, but 720/10bit files plays fine(ZDMC)

So, can you fix this?
My biggest concern is 1080/10bit files
Thanks in advance

 

I have the exact same issues 1080p is constantly buffering or the sound plays but video freezes, I feel like a fool as I've bigged up this box to all my mates as I read it was capable of 4K but can't even handle 1080p so that is false advertising

 

Six days and no answers...
Knock, knock, what do you sell?

 

do you use kodi or nativeplay?

 

Kodi.
Nativeplay not working with any of 10bit files.

 

Whatever.

Returned the box.
