4. The PC does not properly recognize a Plug-and-Play monitor
or displays black bars or the desired resolution is not a choice.
Each video input to the system has an EDID available for the video
source to read and process. This default EDID should work in most
cases without issues and adjustments can be made on the display
device. If necessary though, the EDID can be modified by the customer
for any of the video inputs by using a Hall Research EDID programmer
(purchased separately).
5. Poor audio quality at the receiving end
Only use powered speakers with the splitter and receivers. It is also
good practice to set the audio level (volume) output of the PC about 1/2
to 2/3 from the maximum and use the volume knob of the speakers to
adjust the volume to the desired level. A low volume signal output
from the PC reduces the signal-to-noise (S/N) ratio, whereas too high
output amplitude can cause saturation and clipping to occur.
4.2 Calling Hall Research
If you determine that your splitter is malfunctioning, do not attempt to
repair the unit. Contact the Hall Research Technical Support Team at
714-641-6607. Before you do, make a record of the history of the
problem. We will be able to provide more efficient and accurate
assistance if you have a complete description including:
• The nature and duration of the problem;
• The components involved in the problem—that is, what type of
cable, makes and models of computers and monitors, etc.
• The results of any testing you’ve already done.
4.3 Shipping and Packaging
If you need to transport or ship your sender: Package it carefully (we
recommend that you use the original container), and before you ship
the unit back to Hall Research for repair or return, contact us to get a
Return Material Authorization (RMA) number.
