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 1.2 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. Were the power to the DisplayPort source turned off prior to installation? If not, restart your computer/video source.
4. What resolution are you trying to reach? The DisplayPort Repeater is tested to support video resolutions up to 4K @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 DisplayPort
Repeater; and between the DisplayPort Repeater and the monitor, is limited 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.
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.
