Are you experiencing trouble in using your monitor? Do you know how to fix it? Have you identified what caused it? Did you try to fix it? If you answered yes, then you need to read further.
There are many related instances where our monitor is defective.
Let's try to examine the different situations and let's try to identify ways in fixing it.

1. Some features of our monitor cannot be used.
   Some monitors have special features and menus that allow the user to further manipulate it.
   Sometimes, we just don't bother this but it becomes evident when the one using has some eye defect.
   This issue can sometimes be caused by outdated drivers.
   Outdated drivers will always have compatibility issues with display devices.
   If you just use the generic display driver on your computer, you can only use the basic device functionalities of your monitor.
   This is because generic drivers are not compatible with the specifications on that particular device.
   
2. Your monitor is powered on but no output is shown.
   There are times when your computer fails to communicate with the monitor.
   It is often manifested on the way the monitor displays graphics.
   If there is no display at all, then there is a problem with the communication process.
   
3. You hear a long beep when you start your computer.
   A long beep is usually an indicator that you have a defective hardware device.
   Sometimes, a long beep can be caused by other things.
   Either way, if you hear a long beep, it could either be that your monitor is defective, or you installed a wrong driver for your monitor.
   
4. Your computer stops responding when it tries to load the operating system.
   There are instances when we observe that the startup process of our computer is successful because it eventually shows a menu where we can choose which operating system to load (if you use dual boot).
   However, when we choose one, the computer just stops responding.
   This is because it tries to load the necessary files to be able to handle the different functions of your graphics device.
   If the computer is having difficulty with this, then it freezes.
   

All of these can be fixed using some troubleshooting steps.
One is to check if there are no connection problems between your monitor and the computer.
Check the cables if there are cuts.
Check the connectors if they are attached securely.
