Hello!

I recently asked a question regarding the SHIELD upscaling in the "Pick the Right Kodi Box" thread, which was probably the wrong place...

I tried to find an answer in this thread with the search function but I was not successful..
Hopefully you guys can help me out.

Taken out of my original request here:
http://forum.kodi.tv/showthread.php?tid=...pid2368868

I am currently using a RPi2 running LibreELEC 7.02 (Kodi 16.1) as my main device and I run Kodi on my Samsung Tab S 8.4 too.
In Android, I see the option "Enable HQ Scalers for scalings above 0...100%".
When playing a video the scaling methods to select are "bilinear" and "nearest neighbor", but changing does not seem to have an effect when HQ is enabled.
[...]
I am also considering buying an nVIDIA SHIELD box to replace the RPi2 once I buy a 4K TV. I want to be sure to get the best scaling on a 4K TV since the impact is so significant, especially when watching 720p or even SD sources.

Questions:
- Which scaling method is used on regular Android devices (e.g. my Tablet) with the HQ option?
- Which scaling method is used on the SHIELD with HQ enabled (if available)?

EDIT/PS:
All information and/or complaints I could find regarding picture quality and upscaling seem to be older, this is why I am asking...
