不出意外下一代主机升级一大卖点就是HDMI2.1接口。

HDMI 2.1 supports 8K, 10K, dynamic HDR and requires a new cable
The next version of the HDMI standard is version 2.1. It supports up to 10K resolution, dynamic HDR, adaptive frame rate and 4K at 120fps. However, to enable the new features a new 48G cable is required.

HDMI 2.1 supports up to 10K HDR
HDMI is ready to embrace 8K resolution and other new picture technologies but it also requires a new type of cable to enable the 48 Gbps throughput.

In the resolution department HDMI 2.1 supports 8K at 60 pictures per second as well as 4K at 120 pictures per second. The latter is also referred to as HFR (High Frame Rate) and can be relevant for future generations of game consoles. In the small text supports for 10K resolution is highlighted but it is not mentioned in the press release, so it is unclear if there are some limitations.

In the HDR (High Dynamic Range) department, HDMI 2.1 is adding support for ”Dynamic HDR”. This means that HDMI will be capable of passing dynamic metadata for HDR content on a scene-by-scene or even frame-by-frame basis. This is one of the components that make the Dolby Vision HDR format unique but today it requires a DV composer at both the transmitting and receiving end. HDMI 2.1 will be able to transmit it in a standardized fashion.

Adaptive frame rate & better audio support
There is also a new “Game Mode VRR”, which is short for ”variable frame rate”. This is similar to AMD FreeSync and Nvidia G-sync in the PC ecosystem.

With adaptive frame rate the transmitting and receiving device can synchronize the frame rate on the fly in real-time. This is relevant for gaming, including game consoles that have fluctuating refresh rates. Future game consoles could support this feature.

Lastly, a new “eARC” features is highlighted. This is an extension of ARC – audio return channel – to enable support for object-based audio formats such as Dolby Atmos and DTS-X. So if a streaming service offers Atmos sound via the built-in app in your TV you can passthrough the Atmos sound to a receiver via HDMI.


Coming out later in 2017
HDMI 2.1 is backwards compatible with earlier versions, meaning that you can connect any player based on for example HDMI 2.0 or HDMI 1.4.

Some components of HDMI 2.1 will be available via firmware upgrades but other components obviously require new hardware. We have yet to encounter any TVs at CES with HDMI 2.1 ports. The HDMI group says that partners can start implementing the specification in early Q2 2017.

HDMI 2.1 highlights:

Higher Video Resolutions support a range of higher resolutions and faster refresh rates including 8K60Hz and 4K120Hz for immersive viewing and smooth fast-action detail.
Supported resolutions:
4K50/60
4K100/120
5K50/60
5K100/120
8K50/60
8K100/120
10K50/60
10K100/120
HDMI 2.1 Specification supports the latest color spaces including BT.2020 with 10, 12, and 16 bits per color component.
Dynamic HDR ensures every moment of a video is displayed at its ideal values for depth, detail, brightness, contrast, and wider color gamuts—on a scene-by-scene or even a frame-by-frame basis.
48G cables enable up to 48Gbps bandwidth for uncompressed HDMI 2.1 feature support including 8K video with HDR. The cable is backwards compatible with earlier versions of the HDMI Specification and can be used with existing HDMI devices.
eARC supports the most advanced audio formats such as object-based audio, and enables advanced audio signal control capabilities including device auto-detect.
Game Mode VRR features variable refresh rate, which enables a 3D graphics processor to display the image at the moment it is rendered for more fluid and better detailed gameplay, and for reducing or eliminating lag, stutter, and frame tearing.

x1x不就支持吗？需要显示器支持吧？有啥用？

variable frame rate 就是 AMD freesync 2.0 在hdmi上的实现。
将来的电视机一定会支持这个标准。

60帧率都没法普及的主机，支持了这些技术有什么用。

就是因为不够60帧，这些技术才作用大...
不过对于免费版的sync不看好，而支持比较好的成本不低，不知道在电视上能否顺利推广，毕竟这对于电视来说是个比较尴尬的小众需求

这些玩意在30帧以下不起作用，除非主机和电视本身支持高刷新率。（大于75HZ）

升级狂魔hdmi啊！游戏机玩游戏没有电脑专业哦

毫无压力，LG 2017年款5个型号的oled电视全部是支持4k 120hz的面板，以后更不用说了。

HDMI2.1上RGB 4K HDR毫无压力啊。

为什么电影一般都是24 fps就可以。游戏要60帧率。是因为游戏的帧率是一个波动的范围，不像电影电视是个稳定的刷新频率。号称有60fps其实是在 50~ 65 fps波动。游戏帧率变化时就会与电视机本身固定的刷新频率不匹配，
画面产生撕裂感 。游戏的帧数高比帧数低的画面撕裂感要轻微。但是假设电视是 variable frame rate。也就是电视的刷新率是由游戏视频信号控制的话。那么原理来说 游戏40帧左右就能达到游戏60帧左右的smoothness。
不会存在游戏画面和电视机刷新帧率不同步的情况。

在我看来。影响游戏画质的排名是 hdr > variable frame rate > 4k 这样。 既然hdmi 2.1（hdmi 2.0b） 把amd freesync( vff ) 纳入标准。加上xbox x铺开。带vff 的电视机铺开可能会比在显示器上要快。

这个技术不小众吧。
欧美日发达国家主机玩家是主流，电视厂家必须得把主机支持好才有人买。

印象最深的，就是去年PRO 的HDR游戏刚出时，因为HDR会增加电视输入延迟，于是国外论坛上N多人签名要求LG 出新固件加入HDR游戏模式来减轻延迟，LG果然也是很快就更新固件解决这个问题了。

所以说在欧美日发达国家主机影响力比天朝大多了

电视机不接收120hz的视频信号，目前电视机的120hz都是用来给60hz画面做插帧用的。

这对于主机来说，改善最大的就是介于30到60帧之间波动的情况

另外，这一代主机帧数不行不就是CPU拖后腿么，下一代主机肯定换更好的CPU，到时60帧有什么难得？
