How do I split the signal from the cable box into two different signals?
You can connect the cable receiver box to the main cable line through the input port.Attach another cable to the receiver.Depending on how many TVs you are connecting, connect the cable's other end to a two-way splitter or multi-port switch.
Why does my splitter not work?Not having a strong enough signal to power each device is a common problem with splitters.If cheap cables are used, this can happen.A high quality splitter will reduce the loss even though it will cut back on signal strength.A weak signal can be caused by cables that are too long.
The cables can easily be configured to split a line.The original signal is shown on all of the connected devices.
You can't split or combine two inputs into a single jack, but you have a few options.If you want to use another input on your set that supports high definition video, you can either purchase a simple HDMI switch or an HDMI-switching home theater receiver.
