Characteristics of HDMI splitters:
It displays signals on several display units and no signal loss takes place during transference to the display unit. Display devices can use all the signals at the same time. They generally come with 1080i/p, 720i/p and 480p resolutions. A unique feature of it is that the digital signals do not get diminished with splitting. It is also simple in design and easy to install. Cable and hardware are shielded in order to avoid damage to devices. HDMI is reasonably priced and is robust. It gives high picture quality and has excellent resolution. The HDMI device only splits the original signal that is displayed on all of the connected outputs. The image quality that appears on all output devices will be the same and is not possible to control independently when coupled to an HDMI compatible device such as antennas or any kind of HD receiver.
When to Use an HDMI Splitter
The most common situation where an HDMI splitter is needed occurs when an individual has only one HDMI box and would like the signal to be broadcast to other displays, likely in other rooms or offices. For example, a DVR can be split between two displays in different rooms without having to purchase a second DVR.
An HDMI splitter is often more cost effective than buying a duplicate item. One consideration when using an HDMI splitter is the wiring needs to be run between the two displays. This is sometimes complex depending on the circumstances.
How do HDMI Splitters Work
An HDMI splitter is a small electronic device used to duplicate a single HDMI signal and output it several times. Powered HDMI splitters will act as a repeater to boost the digital HDMI signal and allow you to surpass the normal 15ft length limitations of the format. Splitters will also dynamically handle the EDID handshaking and HDCP signal that HDMI sources and displays need in order to function.
HDMI splitters take a signal in from a source device and then send that exact same signal out to multiple displays. Since HDMI as a signal format is capable of digital handshaking the splitter can read and match the signal that each display device is expecting. This cuts down on signal incompatibilities and setup hiccups, it also means that the splitters will output video at the lowest common denominator (e.g.: if you have a 720p television and a 1080p television both displays will receive a 720p input).
How Do I Use My HDMI Splitter?
Deploying an HDMI splitter is as simple as plugging it in, setting it somewhere unobtrusive, and forgetting about it. Imagine, for instance, that you have one Blu-ray player, cable television box, or game console in your living room. That device has one HDMI port through which it outputs video. But you have a television in the living room and a television in the den too. How do you get the signal to both displays? Simple!
All you need is a 1x2 HDMI splitter and the HDMI cables to run out to your devices. The Blu-ray player will plug into the HDMI splitter, and the HDMI splitter will plug into both televisions. Both televisions will get the same picture, full high definition; full surround sound audio; that the Blu-ray player is sending out.
Conclusion
An HDMI splitter is a very useful device that allows audio as well as video content and provides uncompressed sound and image quality. It is an excellent device which can help you connect HDTV devices, such as DVD players, D-VHS players, or set top boxes two more than one HDTV displays simultaneously.
