The procedure for doing this varies between monitor models so please see your monitor's manual for further instructions. Re-setting the monitor defaults may resolve any no signal problems. Again, you will be able to verify if the adapter is the root cause if the fault follows the adapter or not. If an adapter must be used, try using another adapter from a known working monitor setup. If possible, try to remove the adapter and connect the cable only to the monitor and system. Adapters are used to change or pass through the signal from one standard to another (for example, a DVI to VGA adapter). If the fault follows the suspect cable then the cable is at fault but if it stays with your multiple monitor configuration then the cable is free of problems.Ĭheck to see if an adapter is being used. If you are able, try swapping cables with those from a known working monitor setup. The connections for your cables should be free of any damage (for example, bent or sheared pins). Check your power and signal cables for any damage.These steps may help identify whether there is a problem with your monitor or with the configuration of your multiple monitor setup. No signal issues are usually identified by examining the power button LED (for most monitors, this will be amber in color if there is an issue) or by seeing a "No signal" alert on the screen. Before proceeding with troubleshooting multi-monitor issues, please verify that the multiple monitors are set-up correctly by following the guide in the following article:
