This HDMI splitter with ARC pass is a real novelty. This makes it possible to operate a splitter between the sound system and TV & projector and still use ARC. So if you want to hear the sound from smart TV apps or the internal tuner for satellite or cable TV through your system, this splitter is ideal. Of the ARC (Audio Return Channel) from the TV on output 1 is passed through to the input. As usual, you can also control the volume with the TV remote control, because HDMI-CEC is also allowed through.
ARC Passport
If you want to use the splitter on the output of an AV receiver, please connect HDMI ARC or eARC of a TV to HDMI Output 1. You can then play the audio from the internal tuner or smart TV apps through the AV receiver. ARC operation must be set on the television and on the AV receiver.
Automatic scaler
In principle, no different format can be delivered to 2 end devices. The HDMI source has only one output and can therefore only deliver one specific format. The splitter only distributes what comes in.
However, all of our splitters have a useful function and are therefore an exception: If one display supports 4K, but the second display only supports Full HD, the source can still deliver 4K. Then the scaler function works in the splitter (except for 4K 60Hz YUV 4:2:2). The Full-HD device thus receives a video signal that has been downscaled to 1080p, so 4K / 2160p 60Hz becomes 1080p 60Hz. The HDR mode is not changed. The 4K display gets the original resolution.
There is also a second HDMI input that you can use to connect another HDMI source. The output signal is distributed to both end devices, eg TV and video projector. The sound of the second source then does not run through the AV receiver.
Audio and video formats / EDID modes
The devices negotiate the formats among themselves. You can influence this via the EDID control (EDID = Extended Display Identification Data, with which an HDMI sink identifies itself).
COPY
With this setting, the HDMI source only recognizes the HDMI sink on HDMI output 1 and optimizes the output for it. This setting is mostly useful if your main device supports many audio and video formats. It can then happen that your second device does not display any picture or sound. If your main device supports Dolby Vision but the secondary display does not, HDR content will be displayed with distorted colors on the secondary device.
MIXED
With this setting, your HDMI source delivers a signal that both end devices can process. This setting can be useful if you use both end devices at the same time. The "worse" end device limits the possible formats.
DEFAULT
In this mode, the HDMI source is signaled that your end devices support formats up to 4K 60Hz HDR Dolby Vision and 7.1 HD sound formats. The HDMI source will then output the best possible format. If your end device remains silent or delivers a black screen, the format is not supported. Then choose another mode.
Note : Some HDMI sources allow you to set the audio and video output manually, overriding EDID negotiation.
Automatic scaler
In principle, no different format can be delivered to 2 end devices. Exception: One display supports 4K, the second display only supports Full HD and the source supplies 4K. Then the scaler function works in the splitter (except for 4K 60Hz YUV 4:2:2). The Full-HD device thus receives a video signal that has been downscaled to 1080p, so 4K / 2160p 60Hz becomes 1080p 60Hz. The HDR mode is not changed. The 4K display gets the original resolution.
Hints:
A soundbar with only one HDMI connection (this is then an HDMI output with ARC) can Not can be operated sensibly on the splitter. A "real" HDMI input and HDMI output is required.
When changing the settings on the TV or splitter, note that it may be necessary to restart the connected devices. If you do not achieve the desired output or display, please proceed as follows:
- Switch on the desired EDID mode on the splitter and select the desired HDMI source.
- Disconnect all devices from the power supply for a few seconds, i.e. pull out the mains plug.
- Then plug in the power cords and turn on the devices. And in the following order: TV, sound system, HDMI splitter, and finally the HDMI source.
This procedure also helps with other HDMI connection problems.
