Management Settings - Unknown Timing Search *Available in “Full Mode” only
Use this if you are unable to find or detect the incoming full screen signal automatically (applies for
Analog VGA and CVBS video signals only. A PIP or PBP configured signal is not supported). It may
be a customized signal regarding resolution and refresh frequency. In these situations the custom
signal sources can be searched upon or entered manually within the OSD menu and even stored
conveniently. The contents of these submenus are listed below.

Management Settings - Unknown Timing Search - Auto Mode
Try to determine the incoming signal by automatic detection routines which is based on a
known list of properties for resolutions and frequency combinations that fall out, but between
the most common industry standard set of resolutions/refresh frequencies.
Settings as follows:
“Display Size” = Force the Aspect Ratio to either to 4:3, 5:4, 1:1, 16:9 or
16:10
“Execute” = Choose to produce timing table, update the “Blind Mode
Data” and refresh the screen condition using the data of the
timing table. If this procedure seem to fail, use the “Blind
Mode” below to enter values manually.

Management Settings - Unknown Timing Search - Blind Mode
If you know the advanced properties of the incoming signal or want to troubleshoot a
possible detected signal (that seem to have small deviations), you may try to adjust the
values below and see the result in real time. These settings should be performed by a skilled
technician or a individual that has the needed knowledge to do so. Internally these settings
below are saved into a data register called “Timing Table”.
Settings as follows:
“Hor. Resolution” = Set the Horizontal resolution of the timing table.
“Ver. Resolution” = Set the Vertical resolution of the timing table.
“Total Hor. Line” = Set the Total Horizontal Lines of the timing table.
“Hor. Blank Pixels” = Set the Horizontal Start of timing table,
(sync pulse + back porch).
“Ver. Blank Pixels” = Set the Vertical Start of timing table,
(sync pulse + back porch).
“Execute” = Choose to produce timing table and refresh the screen
condition using the data of the timing table.
● Note: You may experience fast, slow flickering or sliding lines during adjustments. This is normal, and
gives the indication that a different setting may have to be adjusted also, since all these functions are
connected to each other in order to create a stable signal that the video controller can display
correctly.
