SMARTSCALE® TECHNOLOGY

PROBLEM – MIXED RESOLUTIONS CREATE INSTALLATION CHALLENGES AND POOR VIDEO QUALITY

Designing matrix switching solutions for distribution of HDMI/HDCP and other mixed analog sources can

be challenging due to the large number of source and destination resolutions within the system. In a

matrix switching environment, each source can only output one resolution at a time. Incompatibilities in

the system can arise when the output resolution of the source is not supported by some or all displays in

the system. This problem is often overlooked in the design process, forcing installers to purchase costly

scalers to overcome the issue.

NON-AMX SOLUTION - DEFAULT TO THE WEAKEST LINK

As a solution, some matrix switchers actively evaluate the EDID files within the connected displays and

present a combined EDID set. Since this process just defines a common resolution between all

connected displays, the highest resolution presented to the entire system will be from the lowest

resolution display. This is often referred to as best common or greatest common resolution (also known

as weakest link). In most cases, it means every source is being forced down to a lower resolution,

meaning poorer image quality and an overall inferior distribution system. Frequently the result is

expensive 1080p displays are being degraded to standard definition resolutions.
