In recent years, 4K content—or Ultra High Definition (UHD)—has become more and more popular. Netflix shoots all of its original shows, like Daredevil and House of Cards, in 4K, giving owners of compatible TVs a viewing experience like never before. Getting 4K to display properly from some services, however, can be tricky.

近年来，4K内容或超高清(UHD)变得越来越流行。 Netflix以4K拍摄所有原始节目，例如《夜魔侠》和《纸牌屋》，为兼容电视的所有者带来前所未有的观看体验。但是，从某些服务中正确显示4K可能很棘手。

您需要第二代消防电视和支持HDCP 2.2的电视 (You’ll Need a Second-Gen Fire TV and a TV That Supports HDCP 2.2)

First of all: this requires the second generation Amazon Fire TV, so if you have the first-gen, you’re out of luck, unfortunately.

首先：这需要第二代Amazon Fire TV，因此，不幸的是，如果您拥有第一代，那么您将不走运。

Furthermore, 4K might not be available on your TV, depending on its feature set and the other devices you have in the chain.

此外，取决于电视的功能集和您所拥有的其他设备，电视上可能无法使用4K。

HDCP, or High-bandwidth Digital Copy Protection, is a standard that protects digital content and makes it much more difficult for digital pirates to “rip.” HDCP 2.2 is the newest version of the standard, and was specifically updated a little over a year ago to protect 4K content. Many popular services have been supporting HDCP 2.2 for a while now—Netflix, for example, requires that the player, the TV, and any other HDMI accessories (like a sound bar) all support HDCP 2.2 before it’ll allow 4K playback.

HDCP或高带宽数字版权保护是一种保护数字内容的标准，使数字盗版者更难以“窃取”。 HDCP 2.2是该标准的最新版本，并于一年多前进行了专门更新，以保护4K内容。许多流行的服务已经支持HDCP 2.2已有一段时间了，例如Netflix要求播放器，电视和任何其他HDMI附件(如条形音箱)都必须支持HDCP 2.2，然后才能允许4K播放。

HDCP 2.2 itself also requires HDMI 2.0, so it’s only available on newer-model televisions. This is where the biggest problem comes into play: all HDCP 2.2-compatible TVs will have HDMI 2.0, but not all HDMI 2.0 TVs will have HDCP 2.2, and it’s not backwards compatible. This basically means that early adopters of 4K TVs will never be able to use the newest standards, because if the TV didn’t ship with HDCP 2.2, it simply doesn’t support it. There is, however, a workaround that might fix this.

HDCP 2.2本身也需要HDMI 2.0，因此仅在新型电视机上可用。这是最大的问题所在：所有兼容HDCP 2.2的电视都将具有HDMI 2.0，但并非所有HDMI 2.0电视都将具有HDCP 2.2， 并且不向后兼容 。这基本上意味着，早期采用4K电视的人将永远无法使用最新的标准，因为如果电视未随附HDCP 2.2，则它根本不支持它。但是，有一种解决方法可能会解决此问题。

To further muck up the situation, not all HDMI ports on compatible TVs will support HDCP 2.2. For example, my TV has three HDCP 2.2-compliant HDMI ports and two non-compliant ports. While some TVs will list on the port if it’s HDCP 2.2-compliant or not, others (like mine), don’t. The only way to tell is research your exact model of TV on the manufacturer’s website. Fun.

更糟的是，并非兼容电视上的所有HDMI端口都支持HDCP 2.2。例如，我的电视具有三个兼容HDCP 2.2的HDMI端口和两个非兼容端口。尽管有些电视会在端口上列出是否符合HDCP 2.2标准，但其他电视(例如我的电视)却不会。唯一的方法就是在制造商的网站上研究电视的确切型号。好玩

Once you’ve done all the legwork, however, getting 4K playback on your TV is pretty simple.

但是，一旦完成所有的工作，在电视上获得4K播放就非常简单。

如何在Amazon Fire TV上启用4K播放 (How to Enable 4K Playback on Amazon Fire TV)

To get 4K playback on your second-generation Fire TV, the first thing you’ll do is scroll all the way to the bottom of the main screen and choose the “Settings” option.

要在第二代Fire TV上获得4K播放，您要做的第一件事是一直滚动到主屏幕底部，然后选择“设置”选项。

From there, just select the first option, “Display & Sounds.”

从那里，只需选择第一个选项“显示和声音”。

Go down to the “Display” option, then select “Video Resolution.”

转到“显示”选项，然后选择“视频分辨率”。

It should be set to “Auto,” which will automatically play in 4K if it’s available. If that’s not the default option, go ahead and select it now.

应该将其设置为“自动”，如果可用，它将以4K自动播放。如果这不是默认选项，请立即选择它。

Unfortunately, there’s no other way to “force” 4K resolution, and it otherwise can’t be selected as the default resolution. If for some reason you’d rather see everything in 1080p, you can select that option here, however.

不幸的是，没有其他方法可以“强制” 4K分辨率，否则无法将其选择为默认分辨率。如果出于某种原因，您希望以1080p显示所有内容，则可以在此处选择该选项。

Once you start watching content in 4K, it’s honestly hard to go back to 1080p. Fortunately, the 4K catalog gets bigger every day, and before too long it’ll be the standard.

一旦开始以4K观看内容，说实话很难回到1080p。幸运的是，4K目录每天都会变得越来越大，不久之后它将成为标准。
