About A/B Mode

  • Business Mode (A): Auto Detection

    Automatically detects the specifications of all connected devices and outputs at the lowest supported setting, ensuring reliable video and audio performance.

    Use Cases:

    1. You are uncertain about the specifications of your display devices, including supported resolutions, refresh rates, and audio channels for each device
    2. You do not need the auto downscaling feature
    3. Use this mode if there is no sound or video when operating in Home Mode (B)

  • Home Mode (B): Auto Downscaling

    This mode optimizes the output for multiple devices by copying the EDID from the first port.

    Use Cases:

    You are familiar with the specifications of your display devices, including supported resolutions, refresh rates, and audio channels, and you require the auto downscaling feature.

    Connection Guidelines:

    1. Ensure that you know the specifications (resolution, refresh rate, and audio channels) of all devices
    2. Connect the highest-spec device to output 1 port. Connect all other devices to output 2, output 3, etc. The splitter will copy the video and audio source information from output 1.
    3. After completing the connections, restart the splitter to apply the new mode.

    Notes:

    1. Video can be downscaled, but audio cannot
    2. Down-scaling mechanism:it is a multiple of 2/3/4/8/16/32, it can bedown-converted if it is evenly divisible
    3. If there is no sound or video, please verify the device specifications or switch to Business Mode (A).

Splitter AB mode explanation and use

  • Default get the distributor, A mode is mixed mode, different interfaces can display two different resolutions at the same time.

    Common black screen problems:

    (1) HD cable is too long (because the output signal of each product is different, for the cable: exclude the short line directly connected to whether it is normal, if the short cable is directly connected to normal, the long cable is not connected to normal, you have to change the HDMI cable with a chip copper cable or high-quality fiber optic HDMI cable).


    (2) Please make sure that the cable you use is in line with the specifications.(Preferably a regular HDMI 2.1 cable.)


    (3) to confirm whether the signal source frame rate support, and to achieve, because A if support to 120HZ high refresh rate, B monitor up to support 60HZ high refresh rate, so that also can not display.


    (3) does not recognize, monitor EDID problems

    Recognition will not be two monitors ID EDID compatibility recognition problems, you can change the B mode, the 1 port connected to the lower resolution of the monitor, so that other monitors will follow the 1 interface resolution.


    (4) connected to the amplifier and monitor, respectively, there is a picture of the amplifier no sound. You can also follow the exclusion line wire is too long, so that the signal source and amplifier audio direct connection whether to support the resolution.
