HDMI切换器（也称为“交换机”）解决了电视附带的HDMI端口数量过多的设备问题。与更换HDMI电缆来磨损(HDMI)HDMI端口相比，这是一个更好的解决方案！
市场上有很多 4K HDMI切换器，因此我们在(HDMI)亚马逊上(Amazon)搜索了一些值得您关注的
最佳HDMI切换器。(HDMI)
寻找适合4K超高清的(Ultra HD)最佳 HDMI 开关的要素(Best HDMI Switch)
尽管HDMI是一个成熟的标准，具有良好的兼容性，但购买合适的HDMI切换适配器却非常棘手。虽然您或多或少应该对任何开关都满意，但有一些关键事项需要注意。
首先，确保交换机满足或超过您的分辨率和刷新率需求。这很大程度上取决于交换机支持的HDMI版本。(HDMI)例如，HDMI 2.1开关应支持 120Hz 的 4K 分辨率。然而，使用旧版本HDMI的更便宜的交换机可能仅支持 30Hz 的 4K。
如果您只观看Netflix、连接蓝光(Blu-ray)播放器或使用 4K 升级DVD播放器，那没有什么问题，因为这些内容源几乎不会超过 30 fps。但是，如果您想使用PlayStation 5(PlayStation 5)或Xbox Series X等游戏机，则至少需要 60Hz 的 4K 分辨率，或者如果您拥有可以以该刷新率运行的电视，则需要 120Hz 的 4K 分辨率。
下一个，也许是最明显的特征是HDMI(HDMI)输入的数量。您需要一个输入数量至少与要连接到电视上每个HDMI端口的(HDMI)HDMI设备数量相同的开关。(HDMI)当然，您可以为每个HDMI端口使用多个开关，大多数电视至少有两个。
检查给定的HDMI开关是否经过了您想要使用的特殊功能的认证，例如Dolby Atmos、Dolby Vision、HDR、Dolby TrueHD、Dolby Digital、DTS-HD Master Audio等。对这些功能的支持是HDMI标准所固有的有问题，并且它们不会总是被提及，但最好仔细检查它们是否适用于给定的开关。
如今， HDCP(HDCP)合规性（高带宽数字内容保护(High-bandwidth Digital Content Protection)）实际上已成为必然，但请检查是否已提及，以防万一。如果您想观看任何受版权保护的内容（包括流媒体节目、 DVD(DVDs)和蓝光(Blu-ray)光盘），
此功能至关重要。
音频功能可以是一个很好的额外功能。某些HDMI交换机提供 eARC HDMI输出端口，用于将音频发送到 AV 接收器或条形音箱。您可能还会看到一些带有集成音频提取器的开关，可让您连接模拟扬声器或耳机。对于没有扬声器的显示器或者您有没有HDMI输入的接收器或条形音箱来说(HDMI)非常方便(Handy)。HDCP 2.3 是撰写本文时的最新版本，但目前市场上的大多数交换机都是HDCP 2.2。
遥控(Remote)器常见于HDMI开关，但在某些情况下，有些可能没有遥控器。对于具有自动切换功能(automatic switching function)的开关，您可能永远不会使用遥控器，但即使是自动开关有时也会出错，因此遥控器仍然是一个不错的方便。
Kinivo的这款切换器是一款出色的全能 4K 60Hz 切换器。它提供 18Gbps 的带宽和自动切换功能。尽管您还获得了无线遥控器。它还勾选了杜比视界(Dolby Vision)和HDR支持。
550BN 拥有大量的五个HDMI输入，这个特殊的捆绑包甚至还配有一根漂亮的编织电缆，用于将交换机连接到电视。
事实上，我们唯一不太喜欢这个开关的是它的设计，但既然你无论如何都应该把它塞到看不见的地方，所以这基本上是无关紧要的。它还提供两年保修，这在一定程度上抵消了其略高的价格。
Zettaguard开关使用较旧的HDMI标准(HDMI)，(Zettaguard)仅支持 4K 30Hz。它通过提供很酷的画中画功能在一定程度上弥补了这一点，而且对于 4 输入开关来说，它的价格也很高。
它正式支持完整的RGB 4:4:4深色彩空间以及LPCM 7.1和Dolby TrueHD音频格式。虽然与 4K 游戏机、4K PC HDMI输出或任何其他需要 60Hz 或更高频率的 4K UHD设备一起使用时，它不是一个很好的选择，但对于预算有限的影迷来说，它是一个很棒的选择。
快速而优雅的解决方案： Gana 铝制双向 HDMI 切换器 2×1(Gana Aluminum Bidirectional HDMI Switcher 2×1)
有时您所需要的只是将一个HDMI输入转换为两个HDMI输入。这就是Gana(Gana)等高质量且廉价的解决方案的用武之地。
这款迷人的铝制开关不仅有多种冷色可供选择，而且还是双向的。这意味着您还可以使用它将单个HDMI源连接到两个显示器。遗憾的是，您无法同时驱动两个显示器，但您可以通过按按钮在它们之间切换。
作为HDMI 2.0设备，这款两端口HDMI开关的频率最高可达 4k 60Hz，也许最重要的是，不需要任何外部电源即可工作，因此实施起来既简单又优雅。为电视的每个HDMI输入源购买一个Gana切换器甚至可能更有意义，使您拥有的端口总数增加一倍。
最(Best)适合Apple TV 4K 兼容性： ROOFULL 5 端口 4K HDMI 切换器(ROOFULL 5 Port 4K HDMI Switch)
这是 Roofull 之前的 5 端口切换器的更新版本，现在配备了HDCP 2.2直通和HDMI 2.0a，使其符合现代标准。如果有HDMI 2.1(HDMI 2.1)就好了，但以这个价格，考虑到很少有人能利用 2.1，这是完全可以理解的。
除了分辨率和刷新率之外，该交换机还支持几乎所有最重要的图像格式、深色深度，并且特别将Apple 4K TV 列为兼容。(Apple 4K)这是一件大事，因为任何拥有 4K Apple TV 的人都知道该设备对某些电缆和开关的挑剔程度是多么奇怪，尽管从纸面上看，它们应该可以工作。
对于大多数人来说，具有三个HDMI(HDMI)输入的切换器可能绰绰有余，花费大约 20 美元购买这样的切换器同时还获得 4K 60Hz 支持似乎好得令人难以置信。不仅如此，这是一个自动切换器，因此附带的遥控器实际上仅供偶尔使用。确实没有什么可抱怨的，即使价格高出 50%，情况也是如此。
Newcare 的设计与我们以前使用的旧复合开关非常相似，当时您必须将旧任天堂(Nintendo)控制台和VHS机器连接到电视的唯一复合输入，但复古机箱内部是一个具有(VHS)HDCP(HDCP 2.3)的尖端HDMI 2.1切换器2.3支持以及您能想到的任何其他音频和视频格式。
它的价格也非常优惠，尽管这需要做出一些牺牲。例如，没有无线遥控器，也不会自动切换。因此，您必须走到它面前才能操作该设备。话又说回来，这高达 8K！
XOLORspace 23051 可能看起来像它的名字一样无聊，但它提供五个HDMI输入，支持 4K 60Hz 和大多数颜色、音频输出和视频格式。遗憾的是，它不支持深色，因此它不是可以使用较新颜色深度格式的高端OLED和 miniLED 电视的最佳匹配，但对于大多数其他主流 4K 显示器来说，这将是一个绝佳的选择。
您可以支付 59 美元获得终身保修，但老实说我们不推荐这样做。用同样的钱再购买两个这样的开关会更有意义。
我们在这里看到的最后一个切换器非常出色。不仅因为它花费数百美元，还因为这个矩阵切换器套件可以覆盖您的整个家庭。它使用HDMI-over-Ethernet，将信号发送到任何可以铺设电缆的接收器。官方说法，最高可达 230 英尺！如果您也有专用的家庭影院空间，或者有多个高清电视(HDTVs)为单个观众提供服务的大面积区域，那么这是一个很好的解决方案。
在过去，这会限制您观看高清视频，但如果您使用更快的以太网电缆(Ethernet cable)（例如CAT5e或更好的电缆），您可以发送 12 位颜色的 4K 60Hz 信号。这款矩阵切换器适用于商业用途，但如果您有一个大房子，例如配备 4K 有线电视盒或蓝光(Blu-ray)播放器，则可以将其共享给最多四台其他电视(TVs)。
该交换机还具有 RS-232 串行端口，这意味着您可以将其连接到HTPC进行控制。您还可以使用红外遥控发射器功能来扩展交换机自身的红外遥控功能。
8 Best HDMI Switchers With 4K Support
HDMI switchers (alsо “switсhes”) solve the problem of haνing too many devices for the number of HDMI ports your TV shipped with. It’s a far better solutіon than wearing out yoυr HDMI ports swapping HDMI cables aroυnd!
There are a lot of 4K HDMI switches on the market, so we’ve scoured Amazon for the handful of the best HDMI switchers worth your attention.
What to Look For in the Best HDMI Switch for 4K Ultra HD
Despite HDMI being a well-established standard with generally excellent compatibility, buying the right HDMI switch adapter can be surprisingly tricky. While you should be more or less fine with any switch, there are a few key things to look out for.
First, make sure that the switch meets or exceeds your resolution and refresh rate needs. This largely depends on the HDMI version the switch supports. For example, HDMI 2.1 switches should support 4K resolution at 120Hz. However, cheaper switches using older versions of HDMI might only have 4K support at 30Hz.
If you’re only watching Netflix, hooking up a Blu-ray player, or using a 4K upscaling DVD player, there’s nothing wrong with that since these content sources almost never exceed 30 fps. However, if you want to use gaming consoles like the PlayStation 5 or Xbox Series X, you want at least 4K at 60Hz, or 4K at 120Hz if you have a television that can run at that refresh rate.
The next, and perhaps most obvious feature is the number of HDMI inputs. You need a switch with at least as many inputs as the number of HDMI devices you want to connect to each HDMI port on your TV. Of course, you can use multiple switches for each HDMI port, and most televisions have at least two.
Check if a given HDMI switch is certified for special features you want to use, such as Dolby Atmos, Dolby Vision, HDR, Dolby TrueHD, Dolby Digital, DTS-HD Master Audio, etc. Support for these features is inherent to the HDMI standard in question, and they won’t always be mentioned, but it’s good to double-check that they work with a given switch.
HDCP compliance (High-bandwidth Digital Content Protection) is virtually a given these days, but do check that it’s mentioned just in case. This feature is crucial if you want to watch any copy-protected content, which includes streaming shows, DVDs, and Blu-ray discs.
Audio features can be a nice additional extra. Some HDMI switches offer an eARC HDMI output port to send audio to an AV receiver or sound bar. You may also see some switches with an integrated audio extractor, which lets you connect analog speakers or headphones. Handy for monitors with no speakers or if you have a receiver or soundbar without HDMI input. HDCP 2.3 is the latest version at the time of writing, but most switches on the market currently will be HDCP 2.2.
Remote controls are common with HDMI switches, but in some cases some may not have one. In the case of switches with an automatic switching function, you may never use the remote, but even auto switches get it wrong sometimes, so a remote is still a decent convenience.
This switch from Kinivo is an excellent all-around 4K 60Hz switcher. It offers 18Gbps of bandwidth, and auto-switching functionality. Although you also get a wireless remote. It also ticks the boxes for Dolby Vision and HDR support.
The 550BN has a generous set of five HDMI inputs, and this particular bundle even comes with a nice braided cable to connect the switch to your TV.
Really the only thing we don’t like all that much about this switch is its design, but since you’re supposed to tuck it out of sight anyway, that’s largely irrelevant. It also comes with a nice two-year warranty, somewhat offsetting its slightly higher price.
The Zettaguard switch uses the older HDMI standard with support for 4K 30Hz only. It makes up for this somewhat by offering a cool picture-in-picture feature and it’s got a great price tag to boot for a 4-input switch.
It has official support for the full RGB 4:4:4 deep color space and LPCM 7.1 and Dolby TrueHD audio formats. While it’s not a great choice to use with 4K gaming consoles, 4K PC HDMI output, or anything else that needs 60Hz or greater at 4K UHD, for cinephiles on a budget it’s an awesome choice.
Sometimes all you need is to turn one HDMI input into two HDMI inputs. That’s where a high-quality yet inexpensive solution like the Gana comes into the picture.
Not only does this attractive aluminum switch come in a variety of cool colors, it’s also bi-directional. This means you can also use it to connect a single HDMI source to two displays. Sadly, you can’t drive two displays at once, but you can switch between them at the press of a button.
As an HDMI 2.0 device, this two-port HDMI switch will go up to 4k 60Hz and, perhaps best of all, doesn’t need any external power to work, so it’s easy and elegant to implement. It may even make more sense to buy one of these Gana switchers for each of your TV’s HDMI input sources, doubling the total number of ports you have.
This is an updated version of Roofull’s previous 5-port switcher, now equipped with HDCP 2.2 pass-through and HDMI 2.0a, bringing it in line with modern standards. It would have been nice to have HDMI 2.1, but at this price and considering that so few people can even take advantage of 2.1, that’s perfectly understandable.
Apart from resolution and refresh rate, this switch supports virtually all of the most important image formats, deep color depth, and lists the Apple 4K TV in particular as being compatible. That’s a big deal, as anyone who has a 4K Apple TV knows how weirdly finicky the device can be with certain cables and switches, even though, on paper, they should work.
For most people, a switcher with three HDMI inputs is probably more than enough, and picking up such a switch for around twenty bucks while also getting 4K 60Hz support seems too good to be true. Not only that, but this is an auto switcher, so the included remote is really only for occasional use. There’s really not much to complain about and that would still be true at a 50% higher price.
The Newcare’s design is a dead ringer for the old composite switches we used back when you had to connect your old Nintendo console and your VHS machine to the TV’s sole composite inputs, but inside the retro chassis is a cutting-edge HDMI 2.1 switcher with HDCP 2.3 support along with just about any other audio and video format you can think of.
It’s also priced incredibly well, although that comes with some sacrifices. For example, there’s no wireless remote, and it doesn’t auto-switch. So you’ll have to walk up to it to operate the device. Then again, this goes up to 8K!
The XOLORspace 23051 may look as boring as its name, but it offers five HDMI inputs with support for 4K 60Hz and most color, audio output, and video formats. Sadly, it does not support deep color, so it’s not the best match for higher-end OLED and miniLED TVs that can use the newer color depth format, but for most other mainstream 4K displays, this is going to be an excellent choice.
You can pay $59 for a lifetime warranty, but honestly we can’t recommend this. It would make more sense to just buy two more of these switches for the same money.
The last switcher we’re looking at here is a doozy. Not just because it costs hundreds of dollars but because this matrix switcher kit can cover your entire home. It uses HDMI-over-Ethernet, to send signals to receivers wherever you can lay cable. Officially, that’s up to 230 feet! It’s a good solution if you have a dedicated home theater space too, or a large area with multiple HDTVs to serve a single audience.
In the past, this would have limited you to HD video, but if you use a faster Ethernet cable such as CAT5e or better, you can send 4K 60Hz signals with 12-bit color. This matrix switcher is meant for business use, but if you have a large house with, for example, a 4K cable box or Blu-ray player, you can share it to up to four other TVs.
This switch also has an RS-232 serial port, which means you can connect it to an HTPC to control it. You could also use the IR remote blaster function to extend the switch’s own IR remote.
