1.9.4 Setup Individual Output Channel
There are totally 9 channel outputs for DVI-VIDEOWALL-9X, 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.
This area demonstrates the resulting selection of the Input video to be display for the selected
Output Channel.
1
“Original Input Video” shows the resolution information of the Input Video to each Output Channel.
It varies up the Input Video
“Selected Area” shows the information of the selected area to be displayed. The numbers will vary
2
according to different settings.
“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.
3
“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.
Define X Total, Y Total, Upper-Left X, Y point coordinates using scroll bars or manually keying in this
4
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.
“Fine Tune by Percentage” provides the alternative to further adjust the position and area defined
in section 4.
For Outward Extension
For Inward Shrink

6
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.
“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.
16
1.9.5 CASCADING
The Avenview DVI-VIDEOWALL-9X can be cascaded with as many as 255 DVI-VIDEOWALL-9X devices.
To cascade two DVI-VIDEOWALL-9X, connect a DVI cable from Local Output of Unit 1 to DVI Input of Unit 2.

1.11 General Troubleshooting
Problem
Possible Solution
Check if AC Power Cord is firmly plugged into DVI-VIDEOWALL-9X
If you are recovering from Power Outage, leave the device OFF for
a while and then power it ON again.
No Power
Make sure all cables are in good working condition and properly
connected DVI-VIDEOWALL-9X.
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.
Off-Center Screen Image, Odd
Colors or No Picture
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.
VGA Source can take up to 10 Seconds before it is recognized
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
Poor Quality Video
Make sure the video source is not compressed and maintains the
highest native resolution
Press “Color Balance” key in “State” for auto configuration.
Wrong Color
Poor Linking
When the linking of the Serial Control cannot work, reboot
DVI-VIDEOWALL-9X to establish the link.

Notice
1. If the DVI or HDMI device requires the EDID information, please use EDID Reader/Writer to
retrieve and provide DVI/HDMI EDID information.
2. All HDMI over CAT5 transmission distances are measured using Belden 1583A CAT5e 125MHz
LAN cable and ASTRODESIGN Video Signal Generator VG-859C.3
3. The transmission length is largely affected by the type of LAN cables, the type of HDMI sources,
and the type of HDMI display. The testing result shows solid LAN cables (usually in bulk cable
300m or 1000ft form) can transmit a lot longer signals than stranded LAN cables (usually in
patch cord form). Shielded STP cables are better suit than unshielded UTP cables. A solid UTP
CAT5e cable shows longer transmission length than stranded STP CAT6 cable. For long extension
users, solid LAN cables are your only choice.
4. EIA/TIA-568-B termination (T568B) for LAN cables is recommended for better performance.
5. To reduce the interference among the unshielded twisted pairs of wires in LAN cable, you can use
shielded LAN cables to improve EMI problems, which is worsen in long transmission.
6. Because the quality of the LAN cables has the major effects in how long transmission distance
will be made and how good is the received display, the actual transmission length is subject to
your LAN cables. For resolution greater than 1080i or 1280x1024, a CAT6 cable is recommended.
7. If your HDMI display has multiple HDMI inputs, it is found that the first HDMI input
[HDMI input #1] generally can produce better transmission performance among all HDMI inputs.
