Quick question here. I play on Ultrawide (21:9) at 3440x1440. The calculator recommends a Coefficient of 0 and then has recommendations to set the individual scopes to a 133 coefficient. Isn't 233 the coefficient number to use, and couldn't I just set that as the main coefficient number and leave the other sliders at 100? Trying to figure things out and would appreciate any help for optimizing my ultrawide display.
