1.85:1 (Flat), 1920 x 1037 pixels TRC < 1, not used
1.78:1 (16:9), 1920 x 1080 TRC < 1, not used
1.66:1 (Vista), 1792 x 1080 pixels TRC < 1, not used
1.6:1 (16:10), 1728 x 1080 pixels TRC = 1, not used (native resolution)
1.33:1 (4:3), 1440 x 1080 pixels TRC = 1.2
1.25:1 (5:4), 1350 x 1080 pixels 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.
