Troubleshooting
1. Is the external power supply that came 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 the power to the connected devices turned off prior to the
installation?
If not, restart them.
3. What resolution are you trying to obtain?
Tripp Lite's 4K UHD B118-008E-UHD-2 HDMI splitter supports video
resolutions up to 4K x 2K (4096 x 2160) @ 60 Hz at 36-bit Deep Color
(12 bits per channel).
4. What type of cabling are you using?
Inferior cabling can result in poor performance. It is important to use
cables that can support the video resolution you are trying to obtain. For
best results, use Tripp Lite's P568-Series High-Speed HDMI cables.
5. Test the cables to ensure they are working.
For example, connect your HDMI cable between a trusted working source
and a monitor that you know works to see if the cable is functioning
properly.
6. Are you connecting monitors that have different maximum
resolutions?
When doing so, the video resolution displayed will be that of the lowest
maximum resolution supported among the connected monitors.
