Total H Res — sets the total number of horizontal pixels in the overall wide screen
display. The formula is:
# screens * horizontal output resolution -
(overlap width * (# screens - 1))
Example : If two screens are used, each with an output resolution of 1024 x
768 and an overlap of 200 pixels, the Total H Res is:
2 * 1024 - (200 * 1) = 1848
As you adjust the Total H Res , the Overlap Width value tracks and the wide
screen markers adjust accordingly.
