[新闻] 下一代主机应该支持AMD FreeSync或者 Nvidia G-sync 这样的技术吧

不出意外下一代主机升级一大卖点就是HDMI2.1接口。
SO....................

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.

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)
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。

更看重RGB HDR 4K的组合
HDMI2.1上RGB 4K HDR毫无压力啊。

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

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?

只支持1080p下的120hz 4k你在做梦
说话别这么冲。

刚才查了下的确RTINGS资料显示是1080P@120hz,4K@60hz。

不过2017年款电视都是HDMI2.0接口,明年新款电视如果能用HDMI2.1接口那么4K@120hz也就不是梦了吧。

还是不行,这和hdmi规格无关,单纯电视本身做不到

为什么单纯电视本身做不到?你是说电视芯片处理能力达不到?

次子和FF15有这个选项?正好2个游戏都有,回去看看去
