C.3.1 COMPUTER MONITOR
This is a subject that could (and does) easily fill multiple volumes, but which we will
sadly give short shrift. It may not be quite as important to achieve ‘spot-on’ color
calibration for the monitor used for the user interface. Not surprisingly, video output
color is best judged on larger downstream video monitors.
Nevertheless, you may find a trip to one of any number of websites providing test
imagery and calibration hints useful. A search for “computer monitor calibration”
will yield an endless list, along with some commercial utilities for those who feel the
need. Here are links to several such sites:

C.3.2 PROGRAM OUTPUT MONITOR
Again, a search of the Internet for “video monitor calibration” will yield a large
number of resources, both free and commercial. If you have television monitors
connected to TriCaster’s outputs, though, you can make further use of the color bars.
The approach is somewhat similar to what we did for our video sources, in that the
first adjustments are to ensure that black and white levels are correct. Color
calibration is performed afterward.
First, warm up your monitor for at least 10 minutes (some sources recommend a half-
hour), to stabilize its output. Dim room lights and window light, to eliminate light
sources that might skew your color perception. Pass the color bars from your camera
through to program output (or use a color bars image in one of TriCaster’s Media
Players for this purpose.

Having set the black and white levels earlier, let’s continue…
