Ay medyo mahina na ako jan pre. Hdr requires a certain brightness peak which the samsung entry uhd isnt really built for. But you can see the pop when you enablle it, although its far from reference. That is why the sony x9000 is popular because of it ability to render hdr better than any other units in its series level. Hdmi advancement naman, im still content with current. Kaya never researched on that. Just dont expect much with the mu or nu. Viewing angle is poor. And its pretty dark for bright rooms. But you do get the uhd which is enough to fill you up to ride along with the resolution hype train.
