Everyone supports HDR10, so this is the primary HDR standard that most people are talking about today. It is the same one used on BluRay UHD discs, and is found in uses elsewhere.
For broadcast, and I believe most streaming, a second “software” based HDR called HLG, or Hybrid Log Gamma, is utilized. So far, the Netflix movies, etc. that I have watched have all lacked HDR, but I expect to see a shift over the next couple of years – likely sooner than later. With projectors, at least, it’s only been about a year since anyone has supported HLG. I assume Netflix, Prime and others will want a decent installed base of “TVs” that can handle it.
The third method is DolbyVision, which is hardware based. You will find that in X-Boxes, but few (I think) consumer TVs at this time.
Superior Color vs. Competitors
The Epson Pro Cinema 6050UB supports and achieves the DCI/P3 color standard. (Eric says they got extremely close – closer than any other lamp-based projector we’ve calibrated.) That is thanks to a Cinema filter that slides into place when you demand the best possible color. While lamp-based DLP competitors can barely get to REC709 (the older color standard and a lot don’t even make it to that!) P3 offers a 50% larger color range, delivering color quality comparable to what the better digital projectors at your local theater complex deliver! True, there are some trade-offs: for instance, the Cinema filter drops the projector’s brightness by about 40%.
From that perspective, you get to choose either more brightness or better, P3 color. I love that you get the choice, unlike the competition. By the way, if you go with a really good laser DLP UHD projector, you can find P3 or close, but those typically run $3K to $6K. Interestingly BenQ’s HT3550 – reviewed earlier this year, has added a “cinema filter” so offers the same type of brighter, with no P3/less bright with. That BenQ is half the price and a favorite, but it is definitely a step down overall. (It’s not as bright, it’s too slow for serious gaming, can’t match black levels, lacks great placement flexibility, etc. But, I think the option with/without a filter, is great because it allows many of us to move projectors out of a dedicated theater.
Many might watch movies at night – if less than a fully darkened room, with “best mode” Digital Cinema with the filter in place, and Using Bright Cinema or Natural without the filter in place for REC709 color during the daytime with more ambient light present.
