Checking External Presentation Devices
The alternate display is set up successfully when the test pattern is displayed on the projection surface
in the meeting room while running the test.
Tip When troubleshooting presentation devices, start with the alternate display test pattern to see if it is set
up correctly and then proceed through VGA and document camera input tests as necessary.
By default, presentations are displayed as presentation-in-picture (PiP) on the main display screen. You
can optionally add an external presentation display screen that displays the presentation instead of
displaying it as PiP. This external display is attached to the External Presentation Display HD video
connection on the codec. See the
Cisco TelePresence System 500 Assembly, Use & Care, and
Field-Replaceable Unit Guide for more information.
Note
If the video works for a few minutes and then stops working, your presentation device might use an
unsupported video protocol. To see the list of displays that the CTS 500 supports, see the release notes
for your CTS software version on Cisco.com.

A PiP softkey will be displayed on the phone only if a PiP is active. Pip is not available for audio-only
calls.

Step 1
Log in to the Cisco TelePresence System Administration interface.
