Best Practices Guide
monitors / displays
If the client does not have an existing video distribution solution, most screens on the market
will work, however the recommendations below will help in the decision on types of monitors
to use:
•
LCD over Plasma
•
Recommended resolution of 1080p and at least 60 Hz. video processing
•
Inputs HDMI, DVI and RGB (PC Input)
If the client has an existing video distribution solution, the recommendations below will help
ensure the monitors take maximum advantage of Marquee:
•
Determine the resolution supported by each monitor. Older monitors may be ED and
not HD, with no HDMI inputs and DVI only.
•
Verify the video processing speed is at least 60 Hz.
•
Identify inputs that can / will be used.
•
Be prepared to use additional engineering solutions, e.g., if you find data not being
retained in the monitors from nightly resets.
•
For best results, all displays connected to a single player should be the same brand,
make and/or model, e.g., size will not matter if this is followed. However, disparate
brands meeting the requirements, etc., may be used.
distance from Marquee player to monitor / display
The second area of concern to any digital signage solution comes with the distance from
player to each monitor. Depending on the processor in each monitor, distances of less than
100 feet may not need any amplification of signal and may be able to split signal to three
monitors using VGA two way splitters and high quality VGA cables. To manage any situation
that is more than three monitors and or a distance of over 100 feet we suggest using one of
the approved methods tested below:
Distances have been tested with splitters in two methods. First is with a standard VGA
splitter. This will take the digital signal and split to two screens, and with additional splitter,
the signal can be sent to three screens. Data can be sent without using distribution amp
under 100 feet and should maintain aspect ratio in each monitor at refresh. The second
method is with HDMI. This should be done on distances of less than 100 feet with a single
matrix distribution system. The equipment tested was an Atlona AT-HD-V14 (1 X 4) with HDMI
cables 1.3 and higher to ensure proper transfer to monitors. For distances over 50 feet, use
an HMDI cable with built in signal repeater. Distances of 100 feet or longer may require
additional engineering and certain products and being released as the test was completed and
at this writing.
The most common digital signage problem will be either loss of signal (connection or
amplification) and will require additional engineering. AV integrators should adhere to best
practices (**scenarios 1 and 2).
