VIDEO AMP MERGED OSD PROCESSOR FOR MONITORS
Repeating line-number can be found by the following formula.
[# of the repeating lines = 2 + N × M],
where N = 1, 2, 3, ... and M = round{14 ÷ (CH[5:0]-18)}.
1. If CH[5:0] is greater than 32 and less than or equal to 46 (32 < CH[5:0] ≤ 46), all lines are repeated once or
twice. The lines that are repeated twice are chosen by the following formula.
[# of the repeating lines = 2 + N × M],
where N = 1, 2, 3, ... and M = round {14 ≤ (CH[5:0]-32)}.
2. If CH[5:0] is greater than 46 and less than or equal to 60 (46 < CH[5:0] ≤ 60), all lines are repeated two or three
times. The lines that are repeated three times are chosen by the following formula.
[# of the repeating lines = 2 + N × M],
where N = 1, 2, 3, ... and M = round {14 ≤ (CH[5:0]-46)}.
3. If CH[5:0] is greater than 60 and less than or equal to 64 (60 < CH[5:0] ≤ 64), all Lines are repeated three or four
times. The lines that are repeated four times are chosen by the following formula.
[# of the repeating lines = 2 + N x M],
where N = 1, 2, 3, ... and M = round {14 ≤ (CH[5:0]-60)}.
CH's reference value is 18, and even if you input 0, it operates in the same way as when CH = 18. The repeating
line-number is limited to 16. If the M value is less than or equal to 1, all lines of the standard font are repeated more
than once.
