HDMI switch is a high definition multimedia interface video switch that allows you to connect several HDMI video sources such as DVD, set-top box or PC simultaneously. It also allows you to switch between these HDMI video sources on a HDMI video display such as HDTV (High Definition Television). In order to transmit encrypted digital streams that are uncompressed, the switch uses an audio/video connector. This video switcher has been made available in 2 and 4 port versions. It supports high resolution video of 1920 x 1200 and achieves sharp HDTV resolutions up to 1080p.
The switch is compatible with all HDMI equipped and HDCP enabled HDTV devices; and is controlled by the push buttons that are placed on the front of the unit. It is generally used in business centers, hotels, restaurants, conference rooms, classrooms and bars.
The 2 port HDMI video switch is not highly preferred as it has only two inputs and one output, and there is no room for future expansion; however the 4 port allows you to switch up to 4 sources and is highly recommended. Also one must see to it that the switch is backward compatible that is it can take the place of a DVI (Digital Visual Interface); in other words you could simply select the exact cables either HDMI or HDMI to DVI, to customize the system.
See to it that the switch comes along with a remote control and a dedicated power adapter; the remote control allows you to select the desired specific channel and the adapter is essential because the switch is powered directly from the HDMI cable that could overload power to the HDMI sources. It is also important that you go for a HDCP compliant switch that allows you to pass data between the source and the monitor.
If you keep in mind the above mentioned points while buying a HDMI Switch, then you could be rest assured to get the best buy and would certainly not regret one bit.
