 So, Why is the DVI Port Not Working?

The DVI port is not working because of software-related issues. It may also be a result of a faulty cable or damaged ports.

So, What Could Be the Reason Why DVI Port is Not Working?

There are several reasons why your DVI port suddenly stops working, and the most prominent reasons are listed below;

  • The DVI to DisplayPort Adaptor is not working
  • The DVI to DisplayPort cable is faulty
  • The DVI is unable to connect to the DisplayPort monitor
  • The DVI port software has not been updated
  • The DVI port setting may be wrong

Fixing The DVI Port Problems

Troubleshooting in different areas is perhaps the best way to discover the issue problem with the DVI port not working. It would be best not to focus on the DVI port only because often, the issue is not with the port but other connected hardware. The following troubleshooting methods are essential;

1. Test Your Monitor with Another Computer

The first step is to rule out any device that couldn’t be the issue. Sometimes, the DVI port may be working, but the monitor is faulty. You should test your computer monitor on another computer. If your monitor turns on and works well, the DVI port or connecting cables or adapter may be the problem. You may need to restart the connected computer to be truly satisfied that the monitor is not the issue.

2. The DVI to DisplayPort Adaptor is Not Working

If you connect your DVI port successfully with the display adaptor and it suddenly stops working, there may be an issue with the adaptor. Troubleshooting issues with the DVI port adaptor are not complex; in most cases, it might be damaged and needs replacement.

Another troubleshooting method for fixing the problem is turning the computer off, turning it on again after a few minutes but boasting into the safe mode. If there was an issue affecting the status of the adaptor, you could quickly revert to the old version in a secure mode.

3. The DVI Hardware Is Not Working

If there is a visual display error from your display port, you may want to check the monitor for signs of damages. The appearance of cracks or horizontal lines on the monitor may signify injuries to the monitor itself. This means you may need to conduct further checks on the hardware of the computer monitor.

Try fixing the monitor issue by removing any item and putting pressure at the back or front. In most cases, you will need to seek the help of a technician in fixing monitor hardware problems.

You must also conduct checks on likely hardware damages to the DVI port and display port. Common port damages are; bent connector pins and deposition of grime and clouds of dust. If the issue is grime or dust, disconnect the system and clean with recommended cleaning solutions only.

 You don’t want to create a short circuit or any other damage by using any cleaning solution or method. A certified computer technician must handle bent connectors and pins to the DVI port. It would be best to watch out for any likely looseness in the connectivity between the DVI and display ports.

You need to pay attention to all connecting cables. Look for any bending, tears, and pinches that could interrupt signals transferred from the DVI port to the signal port. If you have been using the cable for a long time or exposed to dry heat, it could have become dry-rotted. In this situation, an outright replacement of connecting cable is recommended.

Other Issues Relating To DVI Port And Fixing Them

Many other issues may relate to DVI port malfunctioning, and these include the following;

1. You Can’t Connect DVI Port to DisplayPort Monitor

If you can’t connect your DVI to the display port monitor, it could mean there are issues with the computer’s graphics cards. Try and reset or replace your graphics cards while ensuring that new ones are compatible.

You may also want to try and swap ports on the computer’s towers. Check if there are multiple display ports, and then test your computer’s monitors with other options. It would be best if you allowed a competent technician to handle this solution to avoid complicating things.

You should count yourself lucky if the computer comes with a secondary video card. Try and connect the monitor to the secondary card and then remove the first faulty one.

2. Software Related Issues

Sometimes, your DVI port may seem not to be working, whereas there is an underlying software issue. Sometimes, updating your computer’s video driver is all you need to put the DVI and connected components back at work.

There are many DVI driver updates out there, and if you don’t keep up, your DVI port may develop connection issues. If you can set automatic updates for your DVI ports, there should be no need to perform manual updates.

3. To update your DVI port manually

Go to the computer’s property menu and click on the “Properties” button in the dialog, then type your administrator’s password if prompted.

Click on the “Continue” button, and the display adaptor’s property box will be displayed on the screen.

Click on the “driver” tab, then check the last date of your update.

If your update is older than six months, you may manually search for the current updates. If you don’t find any update, updating the software may not be the issue with your DVI port. This does not mean you should not update even if it will not resolve the problem- Click all updates and apply updates manually.

Click on the “Update Driver” button to update the ideal update associated with your DVI and display port. If the update driver option appears, click on “Search automatically for updated driver software.” Once you click an update on manufacturer software, you can check for the update status by clicking on “Browse my computer for driver software”- this will automatically update the software for you.

While your computer is searching for updates, you should avoid doing anything on it. A dialog box should appear after the computer has found the necessary updates. If there is no need to update, you will see the “no update” prompt on the screen. If your automatic update option is on, you will receive a notification that your DVI software has been updated.

Close all windows that are opened while the update is on. Restart your computer if necessary and see if the DVI port works with the connected components.

Keep in mind that you can use another monitor screen if your current monitor is not working.

DVI Issues And Wrong Connection

Often faulty DVI could be a result of faulty connections. If you want to use the Display monitor with your DVI port for instance. Your computer monitor should have some DVI configurations that you may have to adjust to get your DVI working again. The DVI-I, DVI-D, color depth, and refresh rates are just a few of configurations you may have to check to restore your DVI port configuration.

To check your DVI configuration, shut down your computer and turn off the monitor, and let them settle for few minutes before commencing the operations. Disconnect all video cables that runs from the computer tower to the monitor, including the VGA and or HDMI cables.

Locate the DVI port on the back of the Display port before you plug in one of the ends of the DVI cable. The port should be squared shaped and has some pin-outs. Connect the other end of the cables to the DVI port of the computer tower. The DVI port connects directly to the computer’s video card and make sure this connection is tight enough.

Turn on the computer and then the monitor, before pressing the “Reset /DV mode” button or the source button located on the front of the monitor. Continue pressing this option until the word “DVI” appears on top of the screen. You can check if the display port connected to the DVI port is no working.

If your monitor had worked previously before you check the DVI port and other configurations necessary, then the issue will probably be a hardware or software problem. It is better to troubleshoot with one issue the issue with one solution after the other instead of trying to resolve the problem with multiple solutions at the same time.
