What you will need to connect the two televisions:
*Audio/Video cable
*Cable splitter/"Y" splitter.
*Tape measure
1. Determine what type of video and audio cables
you will need. This will depend on the video and
audio source that you want to play on both TVs.
2. Measure the lengths that you need to run cable
from the video source to each TV. Purchase
cables of the type you found from the source in
the correct length. It is usually a good idea to
add a few feet to the lengths of the cable if you
run them over a considerable distance. You will
need cable long enough to reach from the video
source to each TV, as well as a shorter cable,
which can be about 1 foot of the same cable
type.
3. Purchase "Y" splitters for the cable type you
found for the video source. These will be used to
duplicate the audio and video to send to each TV.
4. Attach the short cable to the video source. Attach
the input connection on the "Y" splitter to this
cable. Attach the longer cables to the outputs of
the splitter.
5. Attach the other end of the longer cables to the
TVs.
