NOTE
Input signals with approximately the same frequencies may be regarded as the
same signaL
The following horizontal timing
conditions are recommended (at sync. H.V separate
or H/V composite).
for 31 kHz -52 kHz horizontal frequency:
Horizontal front porch should be more than 0.1 ps.
Horizontal sync. width should be within 1.0 -3.8 ps.
Horizontal back porch should be more than 1.2 I.JS.
Horizontal blanking width should be more than 3.5 ps.
for 52 kHz -100 kHz horizontal frequency
Horizontal front porch should be more than 0.1 ps.
Horizontal sync. width should be within 0.8- 3.0 ps.
Horizontal back porch should be more than 1.1 I-Is.
Horizontal blanking width should be more than 2.3 IJS.
The following vertical timing conditions are recommended.
Vertical front porch should be more than 9 I-IS.
Vertical sync. width should be less than 100 IJS.
Vertical back porch should be more than 400 IAS.
Vertical blanking width should be more than 450 I-Is.
[f either the front or back porch is extremely long, or the data display time is
extremely short, it may not be able to set the expected size and posiiton.
Standard settings are subject to change without notice.
This monitor is tested and conformed compliance with ZH1/618 and EN29241 -3
(1S09241 -3) ergonomics requirement on VESA 1024 x 768- 75Hz video mode.
