Yes to all that, and it will be snappy if you use a wireless remote. The A2 lite is preferred.
This sounds great, thanks. I've always used my Logitech Harmony with Kodi (over Bluetooth) so I'll check if that works first. If not, I'll get back to your recommendation.
In my LE 8.2.4.x Kodi will also resolution switch downwards 4K <<-->> 1080p for video playback.
I'm not sure if Kodi auto resolution switches for 4K pictures, It may work it may not. If it does not just set the Kodi GUI to 4K.
AFAIK resolution switching for pictures is not possible with Kodi. So if the Kodi interface can be rendered at 4K and LE automatically switches down the resolution during video playback (if required) then this sounds perfect to me.
Thanks again for your help. I'll start looking for a good NEO U9-H deal then.
Edit: Darn, I just read about that 10-bit 4:2:2 issue. For me this means no HDR playback then, because my TV does not support 4:4:4@10-bit. I'll keep my fingers crossed that the issue is fixable ![smile :)](https://forum.libreelec.tv/core/images/smilies/emojione/263a.png)
