A.1.16 IMPROVE IVGA SHARPNESS?
The iVGA signal can look ‘soft’ due to "down-scaling" when iVGA scales a high resolution screen
down to a standard definition video signal. Small fonts can become illegible when downscaling is
drastic. Keep this matter in mind when creating presentations or graphics for use with iVGA.
To improve both the quality and framerate for iVGA, consider lowering your external computer's
desktop resolution. This will in turn make everything appear larger, and TriCaster will not have to
scale down as much. (To do this, go to Control Panel | Display | Settings, and then change the
Screen Resolution to something suitably low – perhaps 1024x768 (or even 800x600).
A.1.17 SHOW THE LIVE PRODUCTION DESKTOP ON VGA OUTPUT?
TriCaster’s VGA Output bypasses the video resolution scan-converter to send a high resolution
display to a projector. You can send TriCaster’s own Live Desktop to the projector (without
having to clone displays), as follows:
1. Exit TriCaster to the Administration Desktop.
2. Hold down Shift, and click on the Launch TriCaster link on the Desktop (this allows you
to task-swap between Windows applications).
3. Press windows-d key to minimize TriCaster and reveal the Windows desktop.
4. Navigate to C:\TriCaster\TriCaster iVGA\ and launch NewTek iVGA.exe .
5. Now, press Alt + tab to return to TriCaster, and you will see on the VGA tab that your
own interface is available for projection output.
6. (You can then display the interface and change Input Sources on the VGA tab to also
show the external laptop’s PowerPoint display.)
A.2 LIVE PRODUCTION
A.2.1 SYNCHRONIZE TRICASTE R’S AUDIO AND VIDEO OUTPUT
As for any device, a slight (2-3 frame) delay occurs when audio and video signals pass through
TriCaster (this is referred to a ‘latency’). The actual transit time for audio and video is identical,
so as long as the signals were synchronized at TriCaster’s inputs, they are synchronized on live
output.
