im not so sure too, but it could be from the diff chipset, firmware that each box used.

so far im used minix n nvidia shield. i can see nvidia shield seem like much better quality in term of movie viewing, mostly the contrast n brightness. viewing from same TV set.

The GPU do the magic here.

nope...
normally htpc u need
1. gpu that support 4k 60/100fps, hdr and 3d
2. tv that support at least hdmi 2.0 and above to enjoy 4k 60fps/3d
3. avr that hv hdmi for dolby atmos 😝 output

Buy where ever is cheapest and safest/convenient for you to shop.. Buy at own risk..

Just choose the UK plug. Easier..


Yes, as it ships with the paid (legit, not ehem) version of AirPin Pro software that allows such feature from ios devices.. Confirmed working with ipad Air 2 running latest OS and Minix Neo U1. See no reason why the Neo U9-H and iPhones won't play nice too.. You can mirror, cast, play audio, etc.. Just don't expect to play fast games on the iPad and expect the wireless experience to keep up as the screen refreshes.
Think flight classes... Private Jet > First > Business > Economy*..  I kid... 

Basically, it's like TVs, not all panels are made equal. You can play the exact same HQ file on lower models vs on higher end models and surely notice a difference in pq between both. Similarly, some boxes output better pq than others. Helps the TV image..
