(The Martian as an example).. however.. the colors did look better, though of course darker, with maybe muddier blacks in HDR on my x900 sony.. i was tempted to boost the gamma or black level but didnt want to ruin the picture for non hdr content.. i suppose the similarly might be that many movies arent actually shot in 4k, but 2k, unsure or maybe using a dedicated ($500) uhd player things might be different.

HDR content has the advantage of being brighter and having more steps between luminance values, which can make it look sharper because there is more depth to the image. Your x900 has more than enough brightness to do good HDR without much tone mapping.

Thanks for the good advice and merry Christmas to all.

 Personally, I think the RX 580 is a hot and noisy card. Something to keep in mind.
