If you make sure you cover that, then the other details should all fall into place. In general, though, these are handy tools that can expand your home theater system at a very fair price. Splitters allow you to save money and also have more options when it comes to your home theater system. Why there is no budget version of HDFury Arcana? Is splitting DD Audio and 4K video that expensive? Do HDMI splitters really work? Does HDMI splitter reduce quality?

Shaun Sunday 11th of July Yanking that HDMI cable out every time you want to switch sources is putting wear and tear on your cables and gear. A switch will decrease that wear and tear, extending the life of your gear as well as easing the hassle of using your AV system.
Maybe that TV is in a different room, or maybe in the same room you have a TV to watch during the day and a projector to watch at night. A splitter will duplicate a signal and send it out through multiple HDMI cables. Some splitters are also switches, with multiple "ins" and multiple "outs.
If you want two displays going at the same time, keep in mind the maximum resolution for all is whatever the lowest resolution display is. The splitter won't convert the signal to p just for that TV. In theory you shouldn't have copy protection issues… in theory. You should be able to send any content you want through a splitter to multiple TVs. That's not a guarantee you'll be without issues, though. HDCP " handshakes " are black magic that sometimes can only be resolved by dancing around an HDMI logo painted on your floor in unicorn tears.
This is especially true of older displays and sources. Make sure before you buy it that it passes HDCP. They'll usually say in the product description. Though there are some unpowered splitters on the market, you're probably better off getting a powered one. They're only slightly more money, and there's a better chance your setup will work without dropouts or connectivity issues.
Here's where I mention that some products at Amazon and elsewhere are mislabeled. In the link for splitters above, for example, a few switches showed up, and one I'm looking at you, Techole is a switch, not a splitter, even though the words "HDMI splitter" appear in its description. But now that you've read this far, you know the difference and can shop with confidence, right? Get CNET's comprehensive coverage of home entertainment tech delivered to your inbox.
Splitters, and many switches, will be labeled in their name with the number of inputs and outputs, respectively, separated by an "x". So a "1x3" splitter will have one input sent to three outputs. Meanwhile, unlike the mislabeled devices mentioned above, there are devices that combine a switch and a splitter in the same box.
A "4x2" switch is also a splitter, with four inputs and two outputs. It can send any of four sources to two TVs. If necessary, the HDMI signal can downscale to pixels when connected to a television that can only handle the lower mode.
Users may need to split this signal in order to distribute it among several screens. Such setups are possible via HDMI splitters, which are commonly used in bars, electronics stores, etc. An HDMI cable usually has an end that goes into the device output and another end that has two or more HDMI outputs that have been split from the single line. Alternatively, hardware splitters are connected to the output device via an HDMI cable and are used with an external power source to split the signal among multiple display devices.
These cables can be configured to easily split a line among four or more displays at once. The HDMI splitter only splits the original signal, which is shown on all of the connected devices. A routing switcher places multiple HDMI compatible output sources into a signal that can be changed manually or via remote control and can dictate what output reaches the display s.
HDMI splitter styles, types, and prices vary. It is important to know what the displays need in order to ensure that the HDMI splitter is capable of providing the necessary amount of data transmission for each device connected to it. Important factors are:. Keep in mind that the rate shown on the display will be the rate that the source is transmitting. If a splitter is incapable of the high frequencies needed from the source to the display, the resulting picture may not be smooth enough.
Color Depth — A key factor that determines the HDMI splitter that should be used is the amount of colors that the display device is capable of producing. The splitter must be of high quality in order to get the best color depth.
When possible, a higher quality cable should be used so that the display device can receive the encoding for resolutions exceeding non-digital formats. If the HDMI splitter and cables that are used with the setup cannot transmit the appropriate amount of data, then the signal quality will be lower and a smaller resolution may be the only option available.
Fortunately, the configuration and design of many of the HDMI splitters make it possible for high quality signal to be sent to each and every output that each display device can independently control.
Cables — Cable splitters are designed to simply split the line by duplicating the signal with a simple enclosure through a cable. The usually one or two splits do not use much power, so an external power source is unnecessary. Boxes — Box splitters are designed to provide several more display connections. The hardware for these boxes are generally small, with several output ports aligned throughout the box. The box requires an external power source to provide enough power to split the original line among all the devices that may be connected at once.
Both kinds offer different image qualities depending on the quality of the splitter itself. The materials used must render high display quality in order for each display device that is connected to experience high quality.
An HDMI splitter is designed to effectively split any HDMI originating output signal into additional outputs that can be connected to multiple displays. Select a splitter with the appropriate amount of HDMI output ports. Choosing one with more ports than needed is not necessary but could be useful later on.
