  If you're seeing a blank screen with your Ihse Extender, start by verifying the power supply units and their connection to the power network. Then, check the interconnect cables and connections between the N Unit and CPU Unit. Also, ensure the DVI-D cable is properly connected to the CPU. If a video signal is detected from the source (computer), download DDC information from console monitors and reboot the CPU if needed. Finally, check the DVI-D cable connection to the monitor, ensuring it's secure and of good quality.

Check the USB cable connection to the CPU, and try another USB port if necessary. If there are problems with the USB connection, check the USB cable connection to the USB-HID device. Ensure the USB-HID device is connected. If the USB-HID device is not supported, contact your dealer.
