Audio Visual 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).
