Mut@nt HD51 4K First Impressions.

[Ashley69]

What are your first impressions of the new Mut@nt HD51 4k?

Here are mine.

The box is very fast and responsive.
Build quality as per most Mut@nt boxes.
Remote is very cheap feeling.
Picture quality on HD channels is Fantastic.(connected to my LG UHD TV)
AV output on box set to 2016p multi. Is this right? Does this setting upscale the picture to my TV? I'm asking this because I can't see any noticeable difference from the 1080p settings.
Picture quality on SD channels is terrible. I think I may have to ask for help with the picture settings to improve this.
Vix working nearly perfect. One little bug I found where you can't exit out of input devices menu. Had to unplug to restart the box.
I streamed an UHD film from my NAS and was blown away with the quality. It played perfectly.
Shame it hasn't got transcoding.
Other than SD picture quality the box is very good.
