Troubleshooting
If you are unable to get an acceptable image after following the
installation instructions, try the troubleshooting tips below.
1
Is your equipment running the latest graphics driver? If not, download
the latest graphics drivers for your equipment. Backward compatible
with most DisplayPort 1.1a equipment running current graphics
drivers, with the feature set being limited to that of your equipment
(e.g. you may be limited to displaying in Clone / Mirror mode only).
Compatibility with older graphics cards is not guaranteed.
2
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.
3
Was the power to the DisplayPort source turned off prior to
installation? If not, restart your computer.
4
What resolution are you trying to reach? Tripp Lite DisplayPort Splitters
are tested to support video resolutions up to 4K UHD, 3840 x 2160 @
60Hz. If you are not able to get an acceptable image, try lowering your
computer’s video resolution or adjusting the refresh rate.
5
What length cables are you using? The maximum cable lengths that
can be used between the source and the splitter, and between the
splitter and the monitors, is called out in the Installation section of
this manual.
6
What type of cabling are you using? Inferior cabling can result in poor
performance, so it is important that you use cables that can support
the video resolution you are trying to obtain. It is recommended that
you use the Tripp Lite cables shown in the Optional Accessories listing
in this manual, as they have been tested to work with the B156-
Series Splitters.
7
Test your cables to ensure they are working properly. For example,
connect your DisplayPort cables between a source and monitor that
you know works to see if the cable is functioning.
