How Do I Connect Monitors?

Computer monitor

With the power off, connect an external computer monitor to the Interface port on TriCaster’s backplate, using an adapter if necessary.


Multiview monitor (or projector)

TriCaster supports a Multiview output feature by means of the output connector labeled Multiview.

  1. Connect the external device to the Multiview output on TriCaster’s backplate using an appropriate cable (and/or adapter, if required).

    2. Open a TriCaster session (or create a new one) from the Home Page of the Startup Screen, click the         Live icon on the Session Page of the Startup Screen, and press Enter (or click the Start Live                     Production link).

    3. Click Workspace in the Dashboard at the top of the Live Desktop, and click the Configure (gear)               button that appears above it.

    4. Select a suitable Multiview Resolution from the bottom of the menu shown to match the native                 resolution of the external monitor you wish to use.


Supplementary Questions:

Q1:  Why don’t I see the Multiview monitor resolution I want listed in the Multiview Resolution menu?

A: Normally the Multiview Resolution menu list is updated using DDC (Display Data Channel) information the monitor itself provides.  In some cases this information may not be not available (e.g., a monitor switch or adapter might prevent the available display mode information from being supplied to the operating system).

If you are sure your monitor supports an unlisted mode, you can attempt to add it to the menu manually by editing an (XML format) configuration file supplied for this purpose.  The file is named multiview_resolutions.xml, and is located in the folder at C:\TriCaster\Configuration.  Comments in the file provide details of its use. 

(Note that if your display hardware declines to work with additions you make to the menu, the Live Desktop status message display may show an ‘unsupported display mode’ warning, and the monitor may either revert to the previous mode or simply not show anything at all.)

NOTE: Changing Output Resolution can cause frames to be dropped briefly.  We do not recommend changing this setting during live production.

Q2:  After reconnecting monitors, my Multiview and Interface monitor configuration is messed up.  What can I do?

A: If you disconnect (or power down) and reconnect monitors while on TriCaster’s Live Desktop, the operating system can have difficulty with monitor recognition and configuration.  To avoid problems, naturally it’s best to leave display devices alone while live. 

In the case of an accidental disconnection, avoid reconnecting both monitors at the same time. Rather, allow the display on the first monitor connected to stabilize before connecting the second.


Video Monitors/Devices

Downstream video monitoring devices must be compatible with the video broadcast standard (such as NTSC or PAL) you intend to use in the TriCaster session.

  1. Connect cables between downstream devices (whether monitors or other devices) and appropriately labeled connectors on TriCaster’s backplate (see Section 3.7.1).

    2. Open a TriCaster session (or create a new one) from the Home Page of the Startup Screen.

    3. Click the Live icon on the Session Page of the Startup Screen, and press Enter (or click the Start Live         Production link).

    4. For SD display devices, you may need to adjust the connection options found                                        in Output  Configuration:

         a. Move the mouse over the Program monitor, and double-click to open Output Configuration.

         b. Click the Output tab, and select either Composite + Y/C or Component for Inputs 1-3 according to              the connection type used by devices connected to each output. (Please see Section 3.7 for                      more.)
