Introduction

Real-time communication requirements for displays

We have put in a lot of effort to minimize the camera to screen
delay on our TelePresence endpoints, and also to detect
and compensate for total delay bewteen the audio and video
components.
We recommend that you use displays with low delay to increase
the naturalness of communications. We also recommend that you
test a sample before ordering a large number of displays.
Delay through most displays is often very high (>100 ms) and is
therefore detrimental to real-time communication quality.
The following display settings may reduce the delay:
• Activate "Game" mode, "PC" mode or similar modes that are
designed to reduce the response time and normally also the
delay
• Deactivate motion smoothing, like "Motion Flow", "Natural
Motion", or any other video processing that introduces
additional delay
• Deactivate advanced audio processing, like "Virtual Surround"
effects and "Dynamic Compression", which will make any
acoustic echo canceller malfunction
• Change to a different HDMI input
