What to do if my Eizo Monitor shows 'no signal' message?
- SStephanie JonesAug 18, 2025
If your Eizo Monitor displays a message indicating no signal input or that the input signal is out of the frequency specification range, begin by checking that the external device is turned on and that the signal cable is properly connected. Try switching the input signal and turning the main power switch off and then on again. You may also want to try changing the Signal Format in the Administrator Settings menu. Ensure that the external device is configured to meet the resolution and vertical scan frequency requirements of the monitor. Rebooting the external device might also resolve the issue. If using a graphics board, adjust the settings using its utility. For SDI signal input, try changing the Input Color Format.
