HP Monitor Not Working

You have your cup of coffee. Your mind is ready for the work ahead of you. You turn on your computer – only to find the monitor is not working.

If your HP monitor is not working, make sure the monitor is receiving power. If the light on the face of the monitor is on, the monitor is receiving power. Press the spacebar or move the mouse to get the monitor out of standby mode.

There are several reasons why your HP monitor is not working. The issue could range from faulty cables to a circuitry issue within the monitor. This article will give you some suggestions to try before going out and buying a new monitor.

HP Monitor Not Working

Without a working monitor, it is impossible to use your computer. When troubleshooting issues with your HP monitor, it is best to start with the simplest of suggestions.

As a general rule, if your HP monitor is not working, check the cables connecting the monitor to the computer. If the cables are loose, or if there are bent or missing pins, this will disrupt the video signal coming to the monitor.

The best way to know if the issue is within the HP monitor is to test the monitor on another computer. If the monitor works on another computer, the problem is a bad video card. Downloading and installing the latest drivers for the video card will resolve this issue.

If the screen remains black when connected to another computer, this confirms the issue is within the monitor. Continue reading this article for suggestions on troubleshooting this issue.

HP Monitor Not Detected

Having a second monitor is a great way to expand your desktop and increase work productivity.

However, there can be connectivity issues when trying to get your computer to recognize two monitors.

If your HP monitor is not being detected, check the display adapter. A USB adapter for extra video output is needed to create a separate video signal. Otherwise, your adapter will be duplicating the same video signal causing your second monitor to have no picture.

Issues with drivers or hardware can cause Windows 10 to not detect a second monitor. Before changing settings on Windows 10, try these steps:

  • Refresh the monitor’s connection by removing and reconnecting the cables.
  • Try a different or newer video cable. Older computers use a VGA cable while new models utilize a DVI or HDMI cable.
  • If there are multiple ports for a monitor, try each port to see if another one works.

If you continue having a problem with your monitor, you can manually instruct the computer to recognize the second monitor. When you are in the computer’s settings, go to Display and then choose Setting Up Multiple Monitors. Follow the instructions for your specific system.

Another option is to bypass the cables and connect wirelessly. You will go to Settings and then to Devices. Select Bluetooth & Other Devices and then Wireless Display or Dock. Follow the on-screen instructions to complete the setup.

HP Monitor Not Displaying

After confirming the cables are correctly inserted or you have successfully connected the monitor via Bluetooth, if the monitor is still not displaying, all hope is not lost. There are a few more suggestions we can try.

If your HP monitor initially displays a picture and then goes black, check the monitor’s resolution settings. If the settings are too low, the picture will not display. Settings that are too high will cause the picture to appear distorted.

Sometimes the simplest of things is the answer: make sure the second monitor has power. The second monitor may have a power switch on the back that needs to be turned on.

Another possibility is outside interference. If there are other electrical devices nearby competing for a signal, this could affect the computer’s ability to detect a second monitor. Disconnect all external devices such as printers, cameras, speakers, etc, to see if this resolves the issue.

Computers come with a video card that, over time, could become loose or dirty and this affects the ability of your monitor to work properly. Follow these steps to reseat the video card:

Step 1: After turning off the computer, remove the screws that hold the video card in place.

Step 2: Gently remove the video card.

Step 3: Using a can of compressed air, remove any dust or debris that could get inside.

Step 4: Replace the video card and turn on the computer. If there are still issues with the monitor, you may need to replace the video card.

HP Monitor Not Staying On

Slightly more irritating than the HP monitor not working at all is when it does not stay on. Your train of thought is disrupted which will now affect your productivity.

There are four simple reasons why your HP monitor is not staying on. First, the monitor might not be receiving power from either the wall outlet or the power adapter. Unplug the monitor from all power sources, wait one minute and then reconnect.

A second possibility could be a bad video connection. Remove the video cable that connects from the computer to the monitor and inspect it for loose, missing, or broken pins. Wait a few seconds and then reconnect the cables.

A third possibility could be due to the monitor overheating. If the monitor is in an area that is humid or dusty, heat can become trapped inside. The monitor will shut off to prevent damage to the circuitry inside.

A fourth possibility is the monitor needs to be replaced. If the circuitry in the monitor is bad or there is a short in the wiring, the monitor will go black or shut off completely.

HP Monitor Not Turning On

Your computer is on. You can hear the fan running. You see lights flickering. But your monitor is black.

If your HP monitor flickers or grows dimmer before going dark, the LCD backlighting bulb needs to be replaced. This bulb is responsible for projecting images onto your monitor. Consult your HP manual owner’s manual to find a replacement bulb.

Test the monitor itself to see if it is working. Disconnect the monitor from the computer, then turn the monitor on. If the monitor shows diagnostic information of any kind, you know the monitor is receiving power.

When starting up your computer, listen for any beeps. Beeping lets you know the computer is running. However, a sequence of beeps means your computer is alerting you to a potential problem. A quick Google search will help you decode the message.

A more serious issue resulting in your HP monitor not working is if the computer is trying to boot from the wrong drive. When the computer is unable to find the correct operating system, you will get a black screen with a blinking cursor.

In this case, you will need to update your computer’s basic input/output system (BIOS). This is an update that is best left to the professionals. Contact HP for additional support or contact a local computer repair shop.

HP Monitor Not Responding

The HP monitor could appear to not be working properly when, in fact, the problem is with the brightness level of the monitor. If the brightness level is too low, the screen will appear too dark. Adjusting the monitor’s brightness and contrast settings could solve the problem.

If your HP monitor is not set to the correct display setting, the monitor will not have a full-screen display. To adjust your computer’s display settings, go to System and then Display. Under Display Resolution, choose the recommended settings or see if another setting works better for your monitor.

Under Scale and Layout choose the recommended percentage. Advanced Scaling Settings gives you the option to let Windows adjust display settings. After choosing these settings, restart your computer to see if the changes correct the issue.
