Testing the External Presentation Display
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.
To test an external presentation device, follow these steps:
Step 1
Log in to the Cisco TelePresence System.
Step 2
Navigate to Troubleshooting > Hardware Setup > Presentation Devices.
Step 3
Click the Test Pattern radio button.
Step 4
Click Start to begin the test.
The test pattern should display on the external presentation display.
Step 5
Click Stop to end the testing.
Testing Presentation Devices
The output for presentations is handled by alternate displays, projectors, alternate devices, or
LCD
s.
Input one of these devices can be delivered through a Video Graphics Array (
VGA
) input device (such
as a laptop computer) or through a document camera.
Note
You should run this test only if you have presentation display devices installed.
