TRC table
Alternatively, you can save time by referencing the following table, which shows the TRC value for some popular image formats:
1080p
WUXGA
2.35:1 (Scope),
1920 x 817 pixels TRC < 1, not used
TRC < 1, not used
1.85:1 (Flat),
1920 x 1037 pixels
TRC < 1, not used
TRC < 1, not used
1.78:1 (16:9),
1920 x 1080
TRC = 1, not used (native resolution) TRC < 1, not used
1.66:1 (Vista),
1792 x 1080 pixels TRC = 1.07
TRC < 1, not used
1.6:1 (16:10),
1728 x 1080 pixels
TRC = 1.11
TRC = 1, not used (native resolution)
1.33:1 (4:3),
1440 x 1080 pixels
TRC = 1.33
TRC = 1.2
1.25:1 (5:4),
1350 x 1080 pixels
TRC = 1.42
TRC = 1.28

TRC can only be applied if greater
than 1. If TRC is 1 or less, disregard
it and calculate the throw ratio using
the basic formula.
