HDMI connections require the EDID and HDCP information of source and sink devices for
successful communications.
Please check if the source devices (ex. Blue-ray DVD Player) support auto detection and auto
adjustment of resolution, color deep and audio format.
The mode selection switch is located at the rear panel of the Splitter box.
The original mode setting is modeA.
ATTENTIONS
HDMI®splitter will distribute one resolution only at one time. Please set the output resolution of the
source device first, and make sure the resolution can be displayed on all connected display
devices.
The resolution mode will depend on the first plug-in or first of the sequent display devices that can
successfully communicate with source device. Make sure your display devices can support the
highest resolution as source device can support, and your display devices are HDCP compliant
and fully support HDCP.
If the HDMI Splitter is connected to multiple HDTVs which support different highest resolution
(720p, 1080i, 1080p, 2048p), it is recommend to adjust the output resolution of source device to
match the resolution of HDTV that has lower resolution.
To reset the HDMI Splitter, please unplug the power adaptor, or unplug the power cord from DC
jack; and then plug it back.
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 setting 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 very well at first connection. Please reset your HDMI Splitter by press
the reset key.
Do you connect any recorder that does not support HDCP to the output port of HDMI Splitter?
HDCP may lock up audio part.
5. HDTV and Blue-ray DVD player can support up to 1080p/12-bit, but when I set the Blue-ray DVD
player to auto detection, it always deliver 1080p/8-bit video signal.
Disable the auto detection function of the Blue-ray DVD player, and set the output resolution
and color deep to 1080p/12-bit. (If other connected sink devices can not support 1080p/12-bit
video signal, the sink devices will not show image.)
6. Snowing noise or image interruption occur when use 1080p/12-bit output setting.
Make sure the HDMI cable is capable of transmitting 1080p/12-bit video signal.A High Speed
Rated HDMI cable is recommended.
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 are 3D supported devices and also support the
same 3D format.
Please check the playmode of Blue-ray player has been set 3D mode orAUTO mode for video
output.
Please make sure the video content is 3D content.
10. If the presented picture is not a proper 3D image, please check whether the 3D format of 3D
Blue-ray player and TV (projector) are correct setting.
11. If the presented picture is symmetric, which showed with up and down or right and left symmetric
image, please check whether the TV or projector supports 3D display function and make sure
the function is enabled. If the TV or projector does not support 3D video format, please turn off
the 3D play mode of 3D Blue-ray player.
