Dell Monitor Displayport Not Working

Are you having a problem getting DisplayPort to work with your Dell monitor? You aren’t alone. Here’s how to fix the issue.

One of the most common reasons why DisplayPort will not send a signal is because it is not connected properly. The connector has to be plugged into both the monitor and the computer tightly. If you are able to pull it out easily, then you don’t have it in tightly enough.

DisplayPort has really upped the game when it comes to sending a signal to a monitor. It is beneficial because it sends both a video and sound over a single cable and it does a much better job than HDMI or even DVI.

With new technology always comes new problems and DisplayPort is no different than anything else. Consider the following other options when the connection is not working as it is often easy to fix.

Dell Monitor Displayport Not Working

One thing that you may want to try is using a different cable to plug in your Dell monitor. Of course, you would always want to use DisplayPort if it is available, but checking with HDMI or DVI may help to limit the possible problems.

You should be aware that not all computers are going to send the signal from HDMI to a Dell monitor. In some cases, they require a higher quality option, and DVI may be the lowest quality they choose.

As long as you are using a quality DisplayPort cable, there is no reason why it shouldn’t work for you. That being said, if it isn’t working, look down through the following list and see what works for you.

Damaged Cable – If you are using a damaged DisplayPort cable, it is not going to send the signal to the monitor. You may even get a partial signal, perhaps enough to get video but it may not send both video and sound.

Remove the cable and look it over carefully. If you see any problems with cracks, cuts, or any other issue, replace the cable. You should also never see any exposed wires and you should always replace the cable rather than trying to repair it.

Try HDMI – One of the primary reasons why people use DisplayPort cables is because they are connecting multiple monitors. If you are only connecting a single monitor or perhaps just a secondary monitor, HDMI may provide all that you need.

Unless you are doing some serious gaming or high-quality graphics or video, you are not going to notice a difference between HDMI and DisplayPort. It may just be as easy to switch to HDMI if you don’t need the better option.

Graphics Card – If you have a DisplayPort option on your computer, then it is likely that the graphics card is able to handle it. On the other hand, if you have replaced the graphics card or if you are using an external graphics card, it may not be able to handle the signal.

Malware – If you have any viruses or malware on your computer, it could stop the signal from getting to your monitor. This often happens because the rogue software creates a conflict with a driver or perhaps the software needed to run your monitor.

If you have this problem, it is best if you run a full system scan. You might even need to do an online scan because it could be a new virus. If you find one, take the appropriate action.

BIOS – Start your computer and when you see the Dell logo, press the F2 key. This will allow you to enter the BIOS settings and check everything. You can do a lot of testing in BIOS on the graphics card, monitor, and other things

Safe Mode – You might also want to try booting into safe mode. This is beneficial because it only loads the bare minimum needed to get windows started.

Since you are starting your computer without all of the drivers and software that runs in the background, it will be easy to see if it is a local issue causing the problem.

Try Another Cable – If all else fails, try using a different DisplayPort cable. There may not be any visible signs of damage but it could be something internal. If you try a different cable, it might work.

Dell Monitor Displayport No Signal

If your Dell monitor is not receiving a signal from your computer, then nothing will happen. Here is what to do when your DisplayPort cable stops sending a signal.

The main reason why DisplayPort is not sending a signal is that it is not connected properly. The DisplayPort needs to be fully seated into the port to make the full connection. Firmly push the cable into the port, both on the PC and on your monitor. It could also be a problem with the graphics card.

One of the more common problems we experience with our computer revolves around the graphics card. It is something we may upgrade or even replace. It is also a fairly weak link that can sometimes cause problems.

Test your graphics card by plugging in another device. You can also test the monitor to make sure it isn’t having problems by plugging it into another computer. If needed, replace the graphics card or buy an external card.

Sometimes, you need to restart the computer to refresh the connection. This is done by fully shutting it down and then draining any residual power.

  1. Unplug the monitor from the PC
  2. Unplug all other cables from the PC except the power cable
  3. Remove the battery if you are using a laptop
  4. Shut down the computer
  5. Remove the power cable from the computer
  6. Push the power button and hold it for 30 seconds. This will drain any residual power
  7. Reinstall the battery
  8. Connect the computer and the monitor with the DisplayPort cable
  9. Press the power button on the monitor if needed to turn on the monitor
  10. Power up the computer
  11. Follow and screen prompts

One other problem that could lead to a lack of signal is a damaged DisplayPort cable. It may not be evident with a visual inspection but it could be a problem.

Do not use a cable that is damaged or if it has exposed wires. Do not try to fix a damaged DisplayPort cable.

Dell Monitor Not Recognizing Displayport

When your Dell Monitor is no longer recognizing DisplayPort you want a solution that works. Here is one option that has helped many.

A loose connection is the most common reason why a Dell monitor stops recognizing the DisplayPort cable. It may have enough of a connection to recognize that it is DisplayPort but not enough that it will take full advantage of the signal.

Sometimes, there are multiple ports available in the GPU. This is for the benefit of those who want to connect multiple monitors.

If you have multiple ports but only need to use one DisplayPort cable, try switching to a different port. You may need to reset the primary port to match the one you are using.

Dell Monitor Displayport To HDMI Not Working

Are you trying to convert HDMI to DisplayPort on your PC? If you run into problems, try this solution that has helped many:

One common reason why the HDMI to DisplayPort converter does not work is because of a bad device configuration. We often use converters when we don’t have the proper ports on our computer and, at times, it may not send a signal through the HDMI port unless we have it configured properly.

Another issue that is not the easiest to hear is that the converter is bad and needs to be replaced. Converters tend to be a weak link in the chain and it doesn’t take much for one to fail. If it is under warranty, you may be able to replace it for free.

Try manually setting the HDMI input. This is done by connecting the HDMI cable to the monitor and pressing a control button on the monitor.

Cycle through the settings until you get to the Input setting. Select HDMI and then close out by choosing OK. This should allow the converter to work.

Dell Monitor No Sound Displayport

Are you connected with a DisplayPort cable but not hearing any sound? There is a simple reason why.

Windows tends to want to use their own, internal speakers and it will default to those speakers without any feedback from the user. To fix the problem, go into the control panel and navigate to the audio section. Choose the Dell monitor as the output speakers and close the control panel. This should get things working again.

You may also have a problem with a device causing a conflict. If it continues to be a problem, disable the offending audio output option

Dell Monitor No Displayport/DP Cable Error

There may be times when the Dell monitor refuses to recognize the DisplayPort cable. Try this solution if you are having this issue.

A loose cable is often to blame when you are getting a DisplayPort cable error or a no cable error. Make sure the cable is properly seated and secured to the ports on the monitor and the computer. There may also be an issue with the settings.

In order for things to work properly, you must have the settings pointed to the proper port for the cable. This becomes an issue when it is pointing at the wrong port and a conflict occurs.

Try unplugging the cable, shutting down the computer, turning off the monitor, and reconnecting again. Make sure the monitor is on and turn on the computer. This will often force the computer to see the monitor.

Anytime you are having problems with a Dell DisplayPort not working, check the wires first. If they are loose or damaged, you will not get the proper signal to take full advantage of the cable. In most cases, a loose or damaged DisplayPort cable will just not work.
