HDMI Installation & Troubleshooting

signal longer distances over other

media such as Cat 5e or Cat 6 twisted-pair,

or RG-6 coaxial cable, or over a wireless

connection. The splitters allow multiple

displays to view the same signal and amplify it.

The switches allow multiple sources to connect

to multiple displays.

2. Plug in output and input cables to sources, displays

and any intermediate devices starting at the source(s) and

ending at the display(s). Carefully identify the power supplies that

came with the intermediate equipment. Use a surge-suppressor or

power-conditioner to provide reliable power to the source,

display and intermediate equipment. In a few cases, turning on

an electric dryer or ceiling fan resulted in an interruption to the

picture. Turn on all of the equipment and verify the resolution

on the display.

3. If there is no picture and/or sound, check the resolution setting

on the source and the display and adjust both to be compatible.

There may also be audio settings that need to be considered, if

there is a suitable picture but no audio. Performance of all

sources and displays then needs to be evaluated and in the case

of difficulties, adjusted to the lowest common resolution setting.

If a cable is suspect, replace it with another and if possible

shorter cable. If electronics are suspect, connect the source

directly to the display with a short cable.

4. Frequently a system remembers prior resolution settings and

needs to be re-set. There are usually re-set buttons on the bottom

of splitter and switch housings, which can be used for this

purpose. If this does not provide the desired result, then disconnect

all HDMI and other signal cables as well as power supplies

and power plugs, wait five or ten minutes to allow current to

drain out of the system and re-connect signal cables first followed

by power cables. This results in equipment defaulting to factory

settings and usually solves incompatibility issues.

5. Many times changing the source resolution from 1080p/60 Hz

to the home theater 1080p@24 Hz setting will cure the

incompatibility of the source and the display, including any issues

with intermediate electronics. Some of the value engineered

Blu-Ray players may no longer have this adjustment feature. It

is also likely that many demo disks will only play on the highest

resolution setting, since they are designed to be compatible

with a particular high-resolution type of display.

6. Most HDMI devices automatically try to adjust resolutions to

achieve a resolution compatible with both the source and the

display. When dealing with multiple sources and multiple displays,

it is frequently helpful to test various input and output connections

by swapping cables between input and output ports to maximize

the effects of auto-sensing features. Sometimes a display capable

of receiving a high-resolution signal will be turned off and a

lower resolution display turned on, which may not be capable

of receiving the picture being sent from the source.

7. To function properly, HDMI needs a 5 volt DC current.

Some cable and satellite receivers put out an HDMI signal,

which is lower than 5 volts and the signal will not transmit

properly. If this appears to be the case, check with the service

provider regarding an upgraded receiver. Sometimes projectors

or receivers need software or firmware upgrades to properly

process new signal features. Many have Ethernet connections

for this purpose. Check with the manufacturer is you are unsure.

8. Try and only use factory terminated Cat 5e or Cat 6 cable

assemblies when extending the HDMI signal. It is very difficult

to terminate the RJ-45 8-position modular plugs in the field to

satisfy the requirements of a potential 10.2 GB/s HDMI signal.

Most installers only have a $100 continuity and pair tester and not

the $6,000 tester required to test cable assemblies for 10 Gigabit

operation. Frequently, one or more of the 16 connections is

marginal but the inexpensive tester erroneously indicates that

all is well. If a 3-ft computer jumper works, then the longer

cable is not properly terminated.

9. HDMI over CAT5E/CAT6 or Coax devices in general are

designed and tested to work directly from the Source device to

the Display/HDTV. They should NOT be used in conjunction

with adapters, signal processors, switchers or splitters between

the Source and Display device. Results can be no picture and

Receiver end of HDMI device/wall plate being damaged.

Installers that have worked with HDMI for the last three years

or so have been through all of the experiences mentioned above

and have developed their own procedures for resolving issues.

However, there are many consumers now that are installing their

own HDMI systems without the benefit of experience or training.

We hope all of our customers find this information beneficial.

When dealing with multiple sources and multiple displays, it is

frequently helpful to test various input and output connections

by swapping cables between input and output ports to

maximize the effects of auto-sensing features.
