HDMI stands for high-definition multimedia interface. It transmits high-definition signals, including video, 3D-encoded video, and multi-channel audio. HDMI is the preferred option for home entertainment systems: HDMI Switcher work with Blu-ray players, games consoles, DVD players, and media streamers. High-definition content can be displayed on a computer or TV screen, but when the display device has only one HDMI input it is not possible to connect more than one device at a time. In this case, a games console and a DVD player could not both be connected at the same time. So, using an HDMI switch means that multiple source devices can be connected to a computer or TV, which is a convenient option because the devices do not have to be unplugged when not in use. Moreover, it is not necessary to buy a new TV just because it does not have enough HDMI ports in order to meet the buyer’s needs.
Before buying HDMI switch, consider its features, its compatibility with other devices, as well as how to install and operate it.
Features of HDMI Switches
HDMI switches have a number of features that should be taken into account before buying. The number of ports, the HDMI cable, and the power source play an important role.
Ports on an HDMI Switch
The number of input ports on the HDMI switch varies. More than one port is required so that multiple devices, such as a games console and DVD player, do not have to be unplugged in order to connect a new one. Therefore, buyers should consider purchasing an HDMI switch with as many input ports as are available, so they they can be used as new devices are bought. It is also wise to consider the number of output ports. Basic HDMI switches have only one output, but the buyer may want the ability to transmit a signal to several TVs or projector screens. There are HDMI distribution amps that allow the buyer to connect one device with up to eight screens that then show the same picture. The most complicated input and output system is the HDMI matrix that connects multiple inputs and outputs and offers great flexibility.
Cable for an HDMI Switch
An HDMI cable transmits both video and audio, but occasionally additional audio capabilities are needed to allows for the integration of a source with a surround sound system. Some HDMI switches have optical-audio ports.
Powered Signal Amplification for an HDMI Switch
If the cable for the HDMI switch is very long, that is over 10 metres, then the powered signal amplification helps to strengthen it. This ensures high quality transmissions with a high speed at all times.
Power Source for an HDMI Switch
HDMI switches can be either powered or self-powered. Powered switches are plugged in with an AC adapter, while self-powered devices mean fewer wires around the house. Some self-powered models still have a power supply included in order to ensure that they are still compatible with older HDMI devices.
Audio Return Channel for an HDMI Switch
Some HDMI switches come with extra features that add to the functionality. For example, our offers HDMI switches with an Audio Return Channel (ARC) that increases flexibility by sending audio data to a surround sound controller or an AV receiver. With the ARC, there is no need for a separate audio connection. This is beneficial when the HDMI switch is used with a TV that has a tuner or integrated DVD player, as it allows the audio to be sent from the TV to the surround sound system.
