Disconnect the cables from the product.

Power on the product.
4
If the message Check Signal Cable appears, the product is working normally.
Checking the Resolution and Frequency
For a mode that exceeds the supported resolution(refer to Standard Signal Mode Table), the message Not Optimum Mode will appear for a short time.

The displayed resolution may vary depending on the product or PC system settings.
If the screen remains blank, check the PC
system, video controller and cable.
