How to fix No Signal on display port on Windows 10

Displays are plug & play. A display is one of the most basic components of a computer so it needs to work right out of the box or a user won’t be able to interact with their system. An external display generally cannot show users the BIOS of a laptop which will default to the internal display but it works once you’re on a proper desktop OS.

If you’ve connected a display to your Windows 10 system, but it isn’t working and all you see is a ‘No Signal’ message on your monitor, there’s an easy fix.

Fix No Signal on display port

1. Enable projection mode

Normally, an external display is enabled automatically but sometimes Windows 10 thinks you don’t want your desktop to appear on it.

1. Tap the Win+P keyboard shortcut.
2. A panel will open on the right side of the screen. 
3. From the panel, select either Extend to get the desktop on all (internal and external) screens, or select Second Screen only to get the display on the external monitor alone.
4. The No Signal on display port message will disappear from the monitor and your desktop will appear. Don’t forget to arrange them before you start using them.

2. Change monitor port

There are three different ports that most monitors can use to connect to a Windows 10 system; HDMI, DVI, and VGA. Normally, a monitor will automatically detect which sort of port has been used to connect to a computer. When it doesn’t detect the correct port, you get the No signal on display port message.

1. On your monitor, open its settings. Look for buttons along the front bevel or the side of the monitor to bring up the menu.
2. From the menu, look for an option that allows you to select a port, or an input source. If you can’t figure it out, Google where the option can be found for your particular monitor.
3. Use the input source selection menu to select the port that you’re using and the display will start working.

3. Disconnect/Reconnect

1. Remove the cable that connects the monitor to your system. You can disconnect it from the monitor, or from the system, either one will do the job.
2. Connect it again and it will prompt Windows 1o to start projecting to the new display and it will force the monitor to check for a signal from the newly connected port.

Conclusion

The No Signal on display port is a fairly simple problem but if the above solutions don’t get the display to work, take a look at the cable you’re using. Display ports are incredibly sensitive and the slightest damage to a wire, even if it’s just a twist or bend may impact the signal that is being sent, or you might see lines.
