Screen Position
Screen position is an easy way to fit the visible area of the analog
video signal and the sink device. Actually the horizontal and vertical
positions (Horizontal position and Vertical position) can be set with
two different methods:
▪ Click on the arrows to increase or decrease the H.Pos and V.Pos
values, or
▪ Move the mouse over the visible (grey) area. Click and hold
with the left mouse button. Drag the visible area to the desired
position.
Analog Video Timings
Vertical total: Total line number of the whole image. (The visible and the
blanking area)
Horizontal total: Total pixel number of the whole image. (The visible and
the blanking area)
Horizontal active: Pixel number of the visible image.
Vertical active: Line number of the visible image.
Horizontal/ Vertical position: Horizontal and vertical position values
specify the location of the visible area on the sink device. Black border
on any side of the picture can means wrong settings for the position
of the visible area.
Phase: In case of unclear picture changing pixel phase can solve the
problem. Changing the source device or the cable can cause pixel
phase shifting.
Presets
User's settings for analog video
timings can be set into the UMX-
OPT-TX150R as presets. One
preset contains the following
values which can be set by the user: Horizontal active, Vertical active,
Horizontal position, Vertical position and Phase.
Presets can be assigned for each different resolution to the actual or
to all inputs.
Save to this input: Preset assigned for the current resolution will be set
to the actual input.
Save to all inputs: Preset assigned for the current resolution will be set
to all inputs.
UMX-OPT-TX150R – User's Manual
Undo changes: Backup the last saved preset values. If there were no
saved values it sets up the original settings.
Reload factory settings for this signal: Clear the saved preset for this
resolution from all the inputs, and sets up the original settings.
Analog Gain / Offset
Analog gain / offset window allows users to correct the gain and the
offset values if the automatic mode doesn't give a good result. Gain
and offset settings method are the same:
Step 1. Select the manual mode if the settings need to be changed.
Step 2. Tick the Lock channels if the three components might change
with the same extent.
Step 3. Use the mouse to drag the slider and set to the desired position.
Step 4. Click on the Save button to store the changes.
Preset Manager
User can handle the saved values with the built-in preset manager.
Click on the Preset manager... button and a new window will open.
Presets are showed for the actual input port. Delete record from this port:
Delete the selected preset from only the current port.
Delete record from all ports: Don't need to open every preset manager
for each input port to delete an unwanted preset. Just click the Delete
record from all ports button. Never mind if the selected preset has
different number in the other input properties list, because the device
search by the current resolution.
Clone record to all port: Don't need to reload the saved values and save
to all port. It can be done with only one step. Just select the desired
preset and click the Clone record to all port button.
Columns: User can select which fields will be shown for the saved
presets. The default fields are: Name, V.freq, H.freq, V.pos, H.pos,
V.size, H.size and Phase.
INFO: Analog timing presets can be saved only for the analog input
port so Delete record from all ports and Clone record to all port buttons
are kept for compatibility reasons.
5.4.7. Frame Detector
Click the frame detector button to view the measured detailed timings
on the incoming signal.
The dark grey zone is the blanking area (non-visible) and the light gray
colored zone is the picture (visible area).
INFO: Resolution is given by the source devices always means the
picture (visible area) resolution and the refresh rate means the
VSYNC frequency.
If the Refresh button is clicked on then the UMX-OPT-TX150R samples
and calculates the analog signal values again.
