Common Causes of Flickering
Cable Quality and Compatibility
One of the primary reasons for flickering issues in the KC-KVM303DH is the use of substandard or incompatible cables. Ensure you use high-quality DisplayPort and HDMI cables that meet the required specifications for 8K output. Poor-quality cables can result in signal degradation, leading to screen flickers.
Graphics Card Limitations
The performance of the KC-KVM303DH can also be impacted by the connected computers’ graphics cards. Each computer must support the necessary output formats (two DisplayPort and one HDMI) for optimal performance. If a graphics card cannot handle the required resolution or refresh rates, flickering may occur.
Monitor Compatibility
Each monitor connected to the KVM switch must support the input types and resolutions being transmitted. If one of the monitors is not compatible with the selected input format, it may cause flickering or display issues. Additionally, ensure that the monitors are correctly configured to the appropriate resolution settings.
Troubleshooting Flickering Issues
Check Connections
Start by ensuring that all cables are firmly connected. Loose or partially connected cables can lead to flickering. Disconnect and reconnect all cables, checking for any signs of damage or wear.
Upgrade Cables and Adapters
If you’re using older cables or adapters, consider upgrading to newer, high-quality options designed for 8K support. This can significantly improve signal quality and reduce flickering.
Update Drivers
Ensure that your graphics card drivers are up to date. Manufacturers frequently release updates that can fix bugs or improve compatibility with multi-monitor setups. Check the manufacturer’s website for the latest drivers.
Test Individual Components
To isolate the issue, test each component separately. Connect each monitor directly to the computer to check for flickering. If the flicker occurs only when the KVM is in use, the switch may be the source of the problem.
Adjust Display Settings
In some cases, adjusting the display settings on your computer can help eliminate flickering. Lowering the refresh rate or resolution temporarily can help determine if the issue is related to performance limitations.
