2250 Vertical total too small
There must be at least a total of 5 horizontal scan lines per
frame with interlaced operation.
■
Increase the vertical period so that it’s greater than 4
lines.
■
Switch to non-interlaced operation.
2270 Vertical total is even
There must be an odd numbered total of horizontal scan
lines per frame with interlaced operation.
■
Change the vertical period (in lines) to an even number.
■
Switch to non-interlaced operation.
2280 Vertical total too large
The generator does not support the given vertical period.
■
Decrease the vertical period to less than 4096 lines
per frame if non-interlaced.
■
Decrease the vertical period to less than 4097 lines
per frame if interlaced.
2300 Vertical active too small
There must be at least 1 active horizontal scan line with
non-interlaced operation.
■
Increase vertical active so that it’s greater than 1 line.
2310 Vertical blanking too small
There must be at least 1 line of vertical blanking with non-
interlaced operation.
■
Increase the vertical period.
■
Decrease vertical active.
2320 Vertical active too small
There must be at least 2 active horizontal scan lines with
interlaced operation.
■
Increase vertical active so that it’s greater than 2 lines.
■
Switch to non-interlaced operation.
