10. SETUP INDIVIDUAL OUTPUT CHANNEL
There are totally 12 channel outputs for DVI-VIDEOWALL-12X, and each output can be independently setup to display any
area of the input video. Each output can be with different output resolutions to adapt different combinations of monitors or
projectors.
To select each individual Output to setup with preferable output, please
click on the desired Output, and the control dialog windows will show
up accordingly.

For each display, users can define which area of the input video is to be displayed. Fundamentally, setup the X Total and Y Total
first, and then define the upper-left (X Start, Y Start) and bottom-right (X End, Y End) corners for each display channel. The
control panel to achieve this goal is as shown.
1This area demonstrates the corresponding Video Selection and Monitor of the Input video to be display for
the selected Output Channel.
2
“Original Input Video” shows the resolution information of the Input Video to each Output Channel.
This also varies depending on the Input Video
“Selected Area” shows the information of the selected area to be displayed. The numbers will vary
according to different settings.
3
“Output Resolution”: In this section, you can setup the output resolution for individual Output Channel.
Notice that each display can output at different resolutions depending on supported resolution of the
connected monitor/TV to that output channel.
“Capture Mode Enable” will enable parameters effective. If users disabled this selection, each
output channel will display simply the full display of the input source.
“Auto Apply Settings” will automatically load the new settings into processor.
Clicking on “Update Status” will keep the information of Input video updated
Clicking on “Update Apply Settings” will load the parameters into the video processor.
4
Define X Total, Y Total, Upper-Left X, Y point coordinates using scroll bars or manually keying in this
section. This section will roughly define these quantities which are needed for each Output channel. The
resulting capture area corresponds to the Input video is illustrated in Window to left.
5“Fine Tune by Percentage” provides the alternative to further adjust the position and area defined in
section 4. For Outward Extension For Inward Shrink
By percentage, users need to determine what will be the reference. There are two choices for this part
“Specified Area” and “Full Input”. Normally, “Specified Area” will work more appropriately while
users are dealing with panel masking, because the overlapped masking area will be closed to specified area
instead of full input video.
6
“Fine Tune by Pixel” offers similar approach to adjust the position and area of the Output channel. The
idea behind this section is the same to “Fine Tune by Percentage”. The difference is that the adjustment
is based on Pixel. Users can therefore adjust the Output Channel area based on Pixels.

NO POWER
1. Check if AC Power Cord is firmly plugged into DVI-VIDEOWALL-12X
2. If you are recovering from Power Outage, leave the device OFF for a
while and then power it ON again.
OFF-CENTER SCREEN IMAGE,
ODD COLORS OR NO PIC-
TURE
3. Make sure all cables are in good working condition and properly connected
DVI-VIDEOWALL-12X.
4. Configure the Output video resolution so that it doesn’t exceed the
native supported resolution of TV/Monitor/Projector (Display). Usually a
message of “Out of Range” is display on TV/Monitor.
5. Every time you change the resolution of Input Source, wait 10 – 20
seconds. After the resolution is changed, the selection of Input and the
Display layout mode will return to default. Adjust the Input source and
Display Layout Mode to your requirements again.
6. VGA Source can take up to 10 Seconds before it is recognized
POOR QUALITY VIDEO
7. We suggest you don’t use T-Connectors to split your video source into
images displayed on two difference screens. This lowers the Output video
quality. Use a distribution amplifier instead of T-Connectors
8. Make sure the video source is not compressed and maintains the highest
native resolution
WRONG COLOR 9. Press “Color Balance” key in “State” for auto configuration.
POOR LINKING 10. When the linking of the Serial Control cannot work, reboot DVI-
VIDEOWALL-12X to establish the link.
