DisplayPort is a computer connection format that delivers high performance display feature. You can connect your computer to a monitor with a DisplayPort cable for better display. However, it is possible that you have run into an issue where your monitor has no signal when your devices are connected via DisplayPort. In this case, you need a good fix to solve your problem.
The following are the methods that can help you easily fix your DisplayPort no signal issue:
You may not be aware, but usually the DisplayPort no signal issue comes from improper connection. You have to ensure that the connector has been plugged into the port correctly and it cannot be pulled out too easily.
You can unplug an re-plug the DisplayPort connection. Try pushing the connector further until you feel the pointy bits on the plug lock it in so that it is difficult for you to pull it out.
Restarting and reconnecting your devices is something that you should definitely give a try. It is a simple but sometimes effective way to fix the issue. To perform this method please follow the steps below.
a) Completely turn off your computer and monitor and unplug their power cables.
b) Unplug their DisplayPort connection.
c) Leave them for a couple of minutes.
d) Connect the DisplayPort cable back to the computer and monitor.
e) Plug the power cables back and power the devices on.
If this fix is useful, your DisplayPort connection will work now.
Sometimes the DisplayPort no signal issue may result from faulty and incompatible graphics driver. You should update the driver of your graphics adapter to fix problems of this kind.
One easy and credible method to deal with drivers is to use Driver Easy.
Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.
You can download and install your drivers by using either Free or Pro version of Driver Easy. But with the Pro version it takes only 2 clicks (and you get full support and a 30-day money back guarantee):
a) Download and Install Driver Easy.
b) Run Driver Easy and hit Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.
c) Click on the Update button next to your graphics adapter to download the latest and correct driver for this device. You can also hit Update All button at the bottom right to automatically update all outdated or missing drivers on your computer (this requires the Pro version — you will be prompted to upgrade when you click on Update All).
Your Display no signal problem may be a hardware issue. You can test your DisplayPort connection with another DisplayPort cable or even with another computer or monitor. Check and see if the trouble comes from the cable or from the ports.
If it is your computer or your monitor that is causing trouble, and if they are under warranty, you can contact the manufacturers of your devices for further assistance. They can help you identify the cause of your problem, and have your devices repaired or replaced.
