TETRA VIO
Chapter 3 : OPERATING MODE
3-1. SETTINGS
We recommend resetting the TETRA VIO device to its
default values
, with the front panel display menu
(
CONTROL > Default value > Yes
) before proceeding.
Activate the auto-setting function (Press the SETUP front panel button or select auto-setting with the front panel
display
menu
INPUT > Auto setting
). This function detects automatically the input type of the source connected to
the input connectors. Then the device performs an auto-centering function.
Select the Input status menu
(INPUT > Input status
) to verify the correct detection of the type and format of your
input source. If a wrong message is displayed, select manually the type of your input source (
INPUT > Input # >
Type
). Renew the step
for each input connected to the device.
In case of audio connection, assign the audio input to the needed video input (
INPUT > Input # > Audio input
).
Select the
Output
format
which corresponds to your display device with the front panel display menu (
OUTPUT >
Output format
).
Select one of the
Output rate
available with the front panel display menu (
OUTPUT > Output rate
).
Select the
Output type
with the front panel display menu (
OUTPUT > Analog type & DVI type
).
3-2. DISPLAY DEVICE ADJUSTMENTS
Display the
grid pattern
with the front panel display menu (
OUTPUT > Test pattern > Grid
).
Adjust directly the display device itself, using its position and size controls, to fill the grid pattern in full screen.
3-3. IMAGE ADJUSTMENTS
For each input source connected to the TETRA VIO, make the following adjustments:
Select the source you want to adjust (with the front panel "INPUT SELECTION" buttons).
Select the aspect ratio of your input source with the front panel display menu (
IMAGE > Aspect in
).
Display the centering pattern (
OUTPUT > Test pattern > Centering
).
Press the
Centering
front panel button to automatically position the image in the
Centering
pattern
.
IMPORTANT:
For best results, display a full size bright image (no black border) to perform a centering. If
necessary, correct the adjustment with the position & size functions (
IMAGE > Blanking adjust
).
NOTE:
The centering function is only available for computer sources.
NOTE:
In case of same Input/Output resolution, the centering also achieves automatic pixel clock adjustments. It
may be useful, to improve manually the pixel
clock
and
phase
using the screen menu (
IMAGE >
Optimize > Clock or Phase
).
If needed, make the others adjustments, available in the screen
IMAGE
menu (color, brightness…).
NOTE:
To set the image adjustments to the factory settings, use the
Preset
function (
IMAGE > Preset > Yes
).
NOTE:
The adjustments are automatically stored in NON-volatile memories. The TETRA VIO is provided with 40
NON-volatile image memories. Each of these memories contains the input channel number, the input and
output format parameters and all of the image adjustments (position, size, brightness...). When the 40
memories are used, each new memorization erases the oldest record.
