DETAIL DETECTION MODE SELECTION
Mode A: (Highest Common Factor Mode)
Auto Detection, Lower Standard First
It is recommended to use Mode A for TV wall application, sports bar application, or other
application when different standard (resolution, color deep) HDTVs are connected together.
Source device supports Auto Detection and Auto Adjustment. (Please make sure
the auto functions are active.)
The HDMI Splitter will compare the EDID information of each sink device (HDTV). A lower
standard sink device will be set as the primary sink device to communicate with the source device.
For example, 4 HDTVs are connected to the HDMI Splitter with a Blue-ray DVD player, which supports
auto resolution / color deep detection and auto output signal adjustment. One of the 4 HDTVs supports
resolution in 720p and color deep in 8-bit, two support resolution in 1080p and color deep in 8-bit, another
HDTV supports resolution in 1080p and color deep in 12-bit. The HDTV that has lower resolution and
color deep will be set as the primary HDTV. And the Blue-ray DVD player will automatically deliver
720p/8-bit signal to all connected HDTVs. (Figure 4) If all the connected devices support 3D format, the
system will automatically take 3D play mode as a prior option.
When a new HDTV is connected to the system or the connection is changed, the Splitter will
detect the EDID of the newly connected HDTV.
If the newly connected HDTV supports lower standard in resolution or color deep, the
source device will adjust the output signal to match the HDTV. The picture on every HDTV will
disappear for a few seconds. If the new HDTV supports higher standard, the picture quality on
every HDTV will not change.
Figure 4
HDTV 2 is selected as the primary
sink device.
Blue-ray DVD player delivers
720p/8-bit signal automatically.
Source device DOES NOT support Auto Detection and Auto Adjustment.
The source device will send the signal as the setting of source device. Please set the
output resolution of the source device first, and make sure the resolution can be displayed on all
connected display devices.
For example, 4 HDTVs are connected to the HDMI Splitter which is connected with a Blue-ray
DVD player which DOES NOT supports HDTV resolution / color deep auto detection and auto output
signal adjustment; one of the HDTV supports resolution in 720p and color deep in 8-bit, two of the HDTVs
support resolution in 1080p and color deep in 8-bit, another HDTVs supports resolution in 1080p and color
deep in 12-bit. (Figure 5)
In order to have all HDTVs working, please set the output resolution to 720p and set the
color deep to 8-bit; otherwise some HDTVs will not show picture. Also, if the 3D Blue-ray player
was set 3D mode for play at first, the HDTV or projector without supporting 3D play function would
not be able to show 3D content appropriately.

Output Port Detection Sequence, First Detect First Out
The detection priority is from port 1 to port 4.
It is recommended to connect lower standard HDTV to port 1 to make sure all connected
HDTV can display same image.
Users can assign one sink device (HDTV, Home Theater Receiver or Projector) as the primary
sink device by connecting it to port 1.
Source device supports Auto Detection and Auto Adjustment. (Please make sure
the auto functions are active.)
Sink device that connects to port 1 will be the primary sink device. The source device will set
the output signal based on the primary sink device.
Source device DOES NOT support Auto Detection and Auto Adjustment.
Please set the output resolution and color deep of the source device first, and make sure the
resolution and color deep can be displayed on all connected display devices.
For example, if you set the output resolution and color deep of the Blue-ray DVD player to 1080p
and 8-bit, please make sure all the HDTVs can display 1080p/8-bit (resolution/color deep). If any
connected display device can not support 1080p/8-bit (resolution/color), this HDTV will not show pictures.

TROUBLE SHOOTING
1. When there is no picture presented, please:
Make sure the direct connection from the source device to the display device without the HDMI
Splitter is working.
Check all the connection is correct and all connectors are connected well.
Check the quality of connected cable, and make sure the cable does not damage.
Change the connection sequence of display devices.
Make sure the output resolution of source device can be displayed on all connected display devices.
Reset the HDMI Splitter.
2. How to make sure your input and output devices are suitable with the HDMI Splitter?
Whether all devices are HDCP compliant?
Whether all HDMI cables stay in good quality as well as connectors?
Make sure all HD displays support the same resolution (720p, 1080i, or 1080p).
3. Some of the connected HDTVs show “mode not support”, some HDTVs are working well.
Make sure all HD displays support the same resolution (720p, 1080i, or 1080p) and color deep (8-bit,
10-bit, and 12-bit).
The HDTVs which show “mode not support” may support low color deep.
Try to change the detection mode to Mode A,
Or set to Mode B and then connect one of the non-working HDTV to output port 1.
4. When there is only picture displayed and without sound:
Check all the connection is correct and all connectors connect well.
Check if you connect any DVI interface display device to the splitter, the splitter may use the EDID
information of the DVI interface display device as communication standard. DVI supports only video
transmission. Please change the connecting sequence, and reset the HDMI Splitter. Make sure the
connection is in the HDMI standard.
Check your cable to see if it supports video transmission only or it is damaged.
HDCP may not match well at first connection. Please press the reset key to reset the HDMI Splitter.
Do you connect any recorder that does not support HDCP to the output port of HDMI Splitter? HDCP
may lock up audio part.

7. When resolution could not show in 1080p?
Make sure your sources (HD Player) and displays are fully supporting 1080p.
8. A HDTV and Home Theater Receiver are connected to the HDMI Splitter, but the receiver delivers stereo
audio to the audio amplifier instead of HD audio (Dolby TrueHD, DTS HD).
The primary sink device may set to the HDTV which may only support stereo audio. Please set the
detection to Mode B. Connect the Home Theater Receiver to port 1, and connect the HDTV to port 2
or other ports. The Home Theater Receiver will be set as the primary sink device.
9. When 3D content could not be shown on your display.
Please make sure your source and displays support 3D and also support the same 3D format.
Please check the play mode of Blue-ray player has been set 3D or AUTO mode for video output.
