I am a beginner as well.

I tested Media Player HiMedia Q10 Pro with 4k contents, it is far superior that any Full HD. Blue ray player can only output to Full HD pictures quality. So blue ray lost a lot. Thus I end up buying the media player. I noticed 4k Video color also more natural to my eyes.

Sound wise, I am using AVR... With DTS HD MA sound track, both media player + blue ray sound similar to me. No differences to me.

Yes... Possible.

However, I prefer media player as it is more convenient, especially with multi-TV setup along with large NAS.

I have 2x Android 4k players and they give perfect results on both large files of 1080p as well as 2160p.

Anyway, my largest file size for 4k is only 68.7GB, less than 70GB... Maybe there are 100GB version that might not be smooth?

Btw, I am running CAT6 and all are confirmed in gigabits mode. For quick check, you can confirm from switches. But if your friend has the good meters, do use them.

One more thing, I found some of the 4k contents are lagging if I play via my desktop i7 6700 (built in graphic). But everything are always perfectly smooth on the Android... Any idea? I need to use install some driver on my desktop? i7 + 64GB RAM must be more powerful than cheapo Android box right?

And of course, some might be asking how about 4k3D or 8k files playback on the Android? I searched the Internet and failed to locate samples to try. I also want to try the 4k recording from Canon 1Dx mark 2 or 5D4, does anyone has them to share?

Correct... IMO, no need to be too fussy on the TV... as long as 4k TV color is not bad already... size from 55" to 65" with entry level 4k is good..

For those perfectionist, of course different story...

Q10 Pro. The default playing app can play all my files from my NAS. And that including 4k media up to 68GB per file (that's the biggest I have).

The only thing I am missing is 4k samples from Canon dSLR (1Dx2 and 5D4). Can anyone share some samples? Need both 30fps and 60fps (1Dx2) to confirm the Q10 Pro performance.

In the past, yes... And very obvious and I had seen Dune perform way better than Android box in 1080p era.

While for 4k, I am not sure... The Android box looks damn good and natural... I am not sure if latest Dune can give better pictures.... And most importantly, can I tell the differences...
