The newest HDTV technology gives us the ultimate in quality video entertainment. These sources are often connected to the finest LCD or LED wide-screen displays, providing astounding clarity and life-like colors. There are owners of these units that require the use of more than one display screen, for various reasons usually involving unusual applications. In some home theaters there may be an advantage to have two displays rather than one. The problem is that HDTV units only have a single output connection. This raises the question, is it possible to split the signal in some way so that the same video can appear on two separate displays at the same time? In other words, can you use one HDTV source connected to two separate display units? The solution to this is a HDMI Splitter box that has one input and two outputs.
This HDMI Splitter is a small unit that provides two identical HDMI outputs that can connect to two displays. Normally the technical specification for HDMI states that the cable length should be less than 16 feet, but with this splitter and due to superb engineering and materials, this HDMI Splitter can drive cables running to displays located as much as 100 feet from the splitter. Again, this splits a single program from a source into two identical displayable signals. If, on the other hand, you have multiple HDMI sources and want to send one or the other to a display than you need a HDMI switch.
It is also important to realize that if the two displays are not the same in terms of resolution, the display having the lower resolution will force the same resolution on the better display. Why this happens is because each display also reports back its display parameters and the splitter then reports back the lowest resolution to the HDMI source, which then adjusts the output accordingly. For more information and a block diagram of how this connects, see the HDMI Splitter website and also check out the FAQ for the complete story.
