If you try a different cable, it might work. There may not be any visible signs of damage but it could be something internal. Try Another Cable – If all else fails, try using a different DisplayPort cable. 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. This is beneficial because it only loads the bare minimum needed to get windows started. Safe Mode – You might also want to try booting into safe mode. You can do a lot of testing in BIOS on the graphics card, monitor, and other things This will allow you to enter the BIOS settings and check everything. If you find one, take the appropriate action.īIOS – Start your computer and when you see the Dell logo, press the F2 key. You might even need to do an online scan because it could be a new virus. If you have this problem, it is best if you run a full system scan. This often happens because the rogue software creates a conflict with a driver or perhaps the software needed to run your monitor. Malware – If you have any viruses or malware on your computer, it could stop the signal from getting to your monitor. 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. Graphics Card – If you have a DisplayPort option on your computer, then it is likely that the graphics card is able to handle it. It may just be as easy to switch to HDMI if you don’t need the better option. 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. If you are only connecting a single monitor or perhaps just a secondary monitor, HDMI may provide all that you need. Try HDMI – One of the primary reasons why people use DisplayPort cables is because they are connecting multiple monitors. You should also never see any exposed wires and you should always replace the cable rather than trying to repair it. If you see any problems with cracks, cuts, or any other issue, replace the cable. Remove the cable and look it over carefully. You may even get a partial signal, perhaps enough to get video but it may not send both video and sound. That being said, if it isn’t working, look down through the following list and see what works for you.ĭamaged Cable – If you are using a damaged DisplayPort cable, it is not going to send the signal to the monitor. In some cases, they require a higher quality option, and DVI may be the lowest quality they choose.Īs long as you are using a quality DisplayPort cable, there is no reason why it shouldn’t work for you. You should be aware that not all computers are going to send the signal from HDMI to a 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. One thing that you may want to try is using a different cable to plug in your Dell monitor. Consider the following other options when the connection is not working as it is often easy to fix. With new technology always comes new problems and DisplayPort is no different than anything else. 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. If you are able to pull it out easily, then you don’t have it in tightly enough.ĭisplayPort has really upped the game when it comes to sending a signal to a monitor. The connector has to be plugged into both the monitor and the computer tightly. One of the most common reasons why DisplayPort will not send a signal is because it is not connected properly.
