8.4" 10.1" HEVC H.265 codec does it play these video`s

Hi.

According to the Samsung website the 8.4" and 10.1" will play the new HEVC H.265 video`s that have the same quality but only half the file size, the 12.2" does not seem to show HEVC H.265 in it` specifications.

Does anybody know, Can you play 1080p HEVC H.265 video files without stuttering?

I have the Tab S 10.5" with the same Exynos 5 Octa 5420 but the stock Samsung video player only gives me an blank screen but the audio play`s

Thanks

John.
