Why Won’t My Benq Monitor Turn On?


Have you ever been in the middle of a task and your BenQ monitor won’t turn on? It can be a frustrating problem, but luckily there are some simple troubleshooting steps that you can take to get your BenQ monitor running again. In this blog post, we will go over the most common reasons why your BenQ monitor may not be turning on, as well as how to fix them. 

1. Check the power cable

The first step in troubleshooting your device is checking the power cable. This is done by inspecting both the power cord and the plug adapter for any signs of damage or wear and tear. If either one appears worn or damaged, it may be necessary to replace them with new parts before continuing with your troubleshooting process. 

The next step is to make sure that your power cord is securely plugged into a working outlet. This can be done by plugging a different device into the same outlet; if the other device powers on, then you know that your outlet is working properly. However, if the other device does not turn on, then there may be an issue with your outlet and you should contact an electrician for assistance. 

It’s important to remember that if your power cord isn’t plugged into a functioning outlet, no matter how secure or undamaged it may appear, it won’t do much good! A secure connection between your device and its source of power is essential for powering up and troubleshooting any electrical equipment. 

2. Make sure the monitor’s power switch is in the “on” position

The next step to making sure that your monitor is powered on is to check for the power switch located at the back of the unit. Most monitors have an “on/off” power switch, which should be in the “on” position when you are using it. If this switch is not in the correct position, then your monitor will not function correctly. To ensure that this switch is in the correct position, simply press it to make sure it clicks into place, and then test your device.  

3. Power Saving Modes 

Many modern monitors also feature a power saving mode which can help conserve energy and extend its lifespan by automatically turning off when it isn’t being used for extended periods of time. This mode can be activated through the same settings menu mentioned above and may need to be disabled if you plan on leaving your computer running for longer periods of time without interruption. 

4. Check for Low Brightness Settings 

If your monitor isn’t coming on, the next thing you should check is the brightness setting. If it is set too low, then the display may appear black even though the monitor is powered on. To adjust the brightness setting, locate and press the “Menu” button on your monitor (this button may have a different name depending on the brand and model).

You should now see an OSD (On-Screen Display) menu with various options such as Brightness, Contrast, Input Source, etc. Navigate to “Brightness” using either the arrow keys or a remote control (depending on which version of monitor you have) and increase it until you are satisfied with the level of brightness.  

5. High Brightness Settings 

This can give the illusion that there’s no power at all because it appears completely white. To adjust this setting, follow the same procedure outlined in the previous section but reduce instead of increasing your brightness level until you are satisfied with how bright it appears onscreen.  

6. Test if your monitor works with another computer or laptop

If all else fails, test if your monitor works with another computer or laptop. This will help you narrow down whether or not it’s a hardware issue or something else entirely. To do this, simply plug in the display cable/port into another computer/laptop and see if everything turns on correctly.

If not, then it’s safe to assume that there’s an issue with either the cable/port itself or with the actual hardware of your monitor.  

7. Update your Benq drivers and firmware, as well as any other related software

Updating Drivers & Firmware on Your Benq Monitor 

The first step in fixing any issue with your hardware is to make sure your drivers are up to date. You can find all the necessary drivers for your Benq monitor on their website, including display driver updates, firmware updates, and other software updates.

To check if your current drivers are up to date, open Device Manager by typing “Device Manager” into the search bar of the Start menu. Once in Device Manager, locate the “Monitors” section and expand it to view details of your Benq monitor. 

Update Drivers from Official Website 

If you notice an exclamation mark next to “Benq Monitor” then it means that there is an issue with one of the device drivers. To fix this problem, you need to download the latest version of the driver from the official website and install it on your computer.

Make sure that you choose the correct version for your model of Benq monitor before downloading and installing it. 

Firmware Updates   

Firmware updates are also important in keeping your Benq monitor running smoothly and efficiently. On rare occasions, outdated or corrupted firmware can cause problems such as flickering screens or blank screens upon powering on the device. Check for new firmware updates periodically using either Windows Update or Benq’s dedicated firmware update tool found on their support page online.

It is important to note that firmware updates should only be done when necessary and not just randomly as they can take a long time to complete depending on how much data needs to be updated since they involve rewriting sections of code directly onto memory chips inside the device itself.  

Other Software Updates                      

Finally, make sure all other software associated with your Benq monitor is also up-to-date—this includes graphics card drivers (if applicable) as well as any display calibration tools like ICC profiles used for color accuracy purposes. Again these can usually be found on either Windows.

8. If all else fails, contact technical support for help troubleshooting the issue

Finally, if all else fails, contact technical support for help troubleshooting the issue or a local technician. They will be able to guide you through more detailed steps such as checking your display settings or updating your graphics card driver if necessary.

Technical support is available 24/7 and can help you get back up and running quickly so you can get back to work without disruption! 

To summarize:

  • The first thing to do when troubleshooting your BenQ monitor is to check the power cable. Make sure it is securely connected and that there are no breaks or frays in the cord.
  • If everything looks good, then try a different outlet for power.
  • If that does not work, then you may need to replace the power cable. 
  • The next step is to check the video cable connection between the monitor and the computer. Ensure that both ends of the cable are connected properly and that they are free from dust or dirt buildup. You should also ensure that both ends are securely attached so they don’t come loose during use.
  • Finally, try using a different video cable if possible, just in case there is something wrong with yours. 
  • If none of these steps have worked, then it’s time to move on to more advanced troubleshooting techniques such as resetting the monitor’s settings or updating its firmware.
  • To reset the settings on your BenQ monitor, press and hold down both menu buttons for 10 seconds until you see a message appear on the screen indicating that all settings have been reset to their default values.
  • If this doesn’t work, then you may need to update its firmware by downloading an update from BenQ’s website and following its instructions for installation carefully. 

On a Final note…

In conclusion, if your BenQ monitor won’t turn on then you should check all cables for proper connections and make sure they are securely attached before attempting any type of advanced troubleshooting steps such as resetting its settings or updating its firmware.

By following these steps closely, you should be able to get back up and running quickly! If all else fails though, consider consulting with an expert who specializes in repairing electronics or replacing parts on monitors like yours. Good luck!
