have MiBox Android TV device connected to my Full HD Samsung (not-so-smart) TV. And when ever I watch a video stream using MiBox, the quality is quite bad.
But when I stream video using my TV native DLNA player, the quality is crystal clear.
Has anyone else noticed this? Is it because MiBox uses a wireless connection which might have smaller bandwidth compared to TV which has network cable connection?
I also have Chromecast2 and had Chromecast1 before, where I also noticed poor video quality. After I upgraded to Chromecast2, which had better wifi reception, the quality went better (but still worse than native TV).
I wonder if it is the poor wifi reception of MiBox or is Android platform as a whole incapable of streaming good quality video stream. I tested multiple apps - youtube, google video, plex, etc. The quality on big screen with MiBox is not so good compared to the same content on my PC computer. Also small screen Android devices have ok picture quality, but maybe that's because the scale is so small and I don't notice the flaws in quality.
EDIT: ---------------------------
So I found solution to my video quality problem. I guess my wifi network is not that consistent which resulted in bad picture quality. After I connected USB-Ethernet adapter, the quality problems were solved. Thank you everybody!
The Mi Box has top spec - fast - Dual Band AC WiFi.
I've never noticed a difference in picture quality between it and a whole bunch of other media players I test - and those use Ethernet. This is when using Netflix, Youtube, Kodi etc etc.
You make no mention of what your WiFi Router capabilities are. If you are using ancient 2.4Ghz only WiFi then expect interference problems.
