1. Best results are usually achieved when the source and display resolu ons are the same. If resolu ons differ,
the extenders will try to adjust the signal to match the resolu on of the HDTV with the lowest resolu on.
This will result in a picture with a lower resolu on on the other HDTV sets.
2. If you do not get audio and video, access the “setup” menu on the TV to adjust the audio and video se ngs.
If the HDMI control circuit cannot establish a handshake, then there usually will be no audio or video in
addi on to a blue or black screen with a statement similar to “this protocol not supported” or “weak signal”.
3. If the above men oned messages display, reset the receiver by disconnec ng the power supply. You can
also disconnect all of the HDMI and power cables, wait 15 minutes for any voltages to decay and then
reconnect all of the cables.
4. If you are s ll encountering issues, a empt the “hot-plug concept. With all of the HDMI cables disconne-
cted, turn on the source and plug in the HDMI cable into its output, then power up the unit and plug the
HDMI cable into its input, finally turn on the display and plug the HDMI cable from the receiver into it. This
ac vates all of the devices in corresponding order and results in a signal being plugged into a device that is
on and will a empt to connect the signal.
5. Most of the major source and display manufacturers employ a proprietary control channel to communicate
between devices from the same manufacturer. Some mes this can interfere with the HDMI control circuit
or the authen ca on of the signal. Call the manufacturer if you experience this issue. Some mes a player,
an audio/video receiver, or a cable/satellite box may not have the latest so ware update, usually this can
be downloaded from the manufacturer's website.
6. If you have problems with the IR control circuit, make sure that the IR RX pigtail is plugged into extender
receiver and pointed at the display, and the IR TX pigtail is a ached to the extender sender and pointed
at the source.
