现在虽然更新4.0，但是HDR还没游戏支持，如果你要试HDR，直接下个营地camp1.2G那个索尼演示片，看看电视 ...

Dolby Vision是需要硬件支持，HDR10不需要

面板亮度不够怎么hdr………怎么忽然冒出来这么多强上hdr的人

面板亮度够不够那是电视本身的参数，合不合适升级成HDR，厂家自然会考虑，然后再决定给不给某个型号的电视升级这个功能。我这里说的是升级为HDR需不需要专门的硬件支持，跟面板亮度没关系。

hx950支持hdr？不可能吧，那么老机器了，我x9000a都不支持

hdr要硬件支持的……
跟面板亮度有很大关系……
不光亮度……
还有其他的你自己看看hdr的资料……

你也别让我看了，不如你自己先看完我贴的这篇，先自己搞明白好吧？这是hometheaterreview.com撰写的HDR科普文。从HDR的概念，到两种格式的技术和软硬件有什么要求，知识产权所属，主流电视品牌对HDR阵营的选择，甚至连选什么阵营和牌子购买的优劣都写得一清二楚了。你看完就发现没什么好争的。。。。

hx950是不支持hdr的，不过支持不等于就是效果好，所以hdr可以在等待观望观望

HDR10 is built around the SMPTE ST 2084 electro-optical transfer function (again, it's the same as Dolby's PQ), and HDR10 content can have similar specs as Dolby Vision content in terms of brightness and color, although the HDR10 profile only lists 10-bit color versus Dolby's 12-bit color. [Editor's note: The original version of the story said that the mastering target for HDR10 is 1,000 nits, but we were informed by a respected source that Dolby Vision and HDR10 are essentially mastered in the same way in terms of nits. It's really dictated by the capabilities of the mastering monitor. Some of the first HDR10 titles were mastered at 4,000 nits, while others were around 1,000 to 1,200 nits.]
The major difference is in how the content is handled at the display end. The HDR10 approach doesn't dynamically map content based on the specific brightness and color output capabilities of a certain TV the way Dolby Vision can, and there isn't a set algorithm to ensure that the color is remapped the same way on every HDR10 display. So, in general, HDR10 is less precise. How that plays out in the real world depends on the specific capabilities/limitations of your TV.

居然会强制切换到hdr，还不能改，果然是高科技
