Expert-Recommended Methods To Fix No DP Signal From Your Device On Dell Monitor?
Method 1: Unplug The Cable
Disconnect and reconnect the connection if you observe “No DP Signal From Your Device” on your PC. Check to see if the DisplayPort on your computer is clear and free of foreign particles before re-establishing the connection. Make sure the cable is correctly plugged into the DisplayPort adapter and that the adapter is properly plugged into the system if you’re using one. Change the line to a different one if the adapter has more than just one DisplayPort port.
Method 2: Install Drivers Related To Your Monitor
Most of the monitors we use today are Plug N Play, but sometimes it becomes essential to install the OEM drivers of the monitor. Some of the features or components of some external screens are powered by native drivers. Install any drivers or companion apps that your monitor requires. There is no DisplayPort signal coming from your device to your monitor. If a support driver or software is needed for the monitor to operate correctly, check the manual or get in touch with the manufacturer.
