Troubleshooting
If you are unable to attain an acceptable image after following the
installation instructions, try the troubleshooting tips below.
1. Is the external power supply that shipped with the product
connected and plugged into a working power source? For the
product to function properly, it must be connected to and receiving power
from the external power supply.
2. Was power to the connected devices turned off prior to
installation? If not, restart the devices.
3. What resolution are you trying to attain? Tripp Lite's UHD 4K x 2K
HDMI splitters are tested to support up to 3840 x 2160 @ 60Hz video
resolution at 36-bit (12 bits per channel) Deep Color.
4. What length HDMI cable are you using? (See the Installation section
in this manual for details on the maximum cable distance.) The shorter
the cable being used, the higher the resolution you will be able to attain.
If you are not able to receive an acceptable image, try using a shorter
cable or lowering the source's video resolution or color depth settings.
5. What type of cabling are you using? Inferior cabling can result in poor
performance, so it is important to use cables that can support the desired
video resolution. It is recommended you use Tripp Lite's P569-XXX-CERT
Series Premium High-Speed HDMI cables, as they have been tested to
work with the B118-Series splitters.
6. Test your cables to ensure they are working properly. For example,
connect your HDMI cable between a source and a monitor that you know
works to determine if the cable is functioning properly.
7. Is the unit located in an area that exposes it to higher
temperatures? If the product is overheated, it will not function properly.
8. Does your display support HDCP 2.2? If your display does not support
HDCP 2.2, you will not be able to achieve 4K video resolution using a 4K
@ 60Hz Blu-ray™ player. When a 4K @ 60Hz Blu-ray player is connected
to a 4K @ 30Hz monitor that supports an HDCP version lower than 2.2,
the video resolution will drop to 1080p.
