When delivering a signal to a monitor, DisplayPort has stepped up the game. It is advantageous since it transmits video and audio over a single connection and performs far better than HDMI or even DVI.
New technology typically brings new difficulties, and “No DP Signal From Your Device” is no exception. If “No DP Signal From Your Device” occurs, try the following other possibilities, which are usually simple to fix.
What Causes the “No DP Signal From Your Device” Issue?
- Defective Cable. If you use a damaged DisplayPort cable, the signal will not be sent to the monitor. You might obtain a partial signal, which could be enough to get video but not both video and sound.
- Multiple Monitors. People use DisplayPort cables for various reasons, one of which is to connect numerous monitors. If you’re merely attaching a single monitor, HDMI might be sufficient.
- Graphics Card. If your computer has a DisplayPort port, your graphics card can certainly handle it. The signal won’t be handled if the graphics card has been replaced or if you’re utilizing an external graphics card.
- Malware. If the computer is contaminated with viruses or malware, the signal may be blocked from reaching your monitor. It happens when rogue software clashes with a driver that allows your display to function.
- BIOS. Start the computer and push the F2 key to see the Dell logo. You’ll be able to access the BIOS settings and double-check everything. In BIOS, you can test the graphics card, monitor, and other components.
- Safe Mode Issue. Also, boot the system in safe mode. It is advantageous since it merely loads the bare minimum required to launch Windows.
