Why Use Dual Monitor?

You may be a gamer or a developer or a general PC user. It is obviously helpful to have an additional display on your PC. Suppose you are a developer, then it will be easy to switch on to different options during developing. Or you are a gamer. Then there is no need to tell the necessity of having a dual monitor because every gamer wants a bigger display for a better visual experience. Actually, most of the users want additional displays not only for getting better visual experience but also for the convenient use of the different software.

Check Necessary Things Before Installing Additional Monitors

Before adding the additional monitor, you should check for your graphics driver, monitors, connectors etc.

Graphics Driver

Your computer may have different graphics cards like Nvidia, AMD or Intel. If you have already used your graphics card through your PC and you are just going to add an additional display, then you probably might have installed drivers for your graphics. But if you are not sure of that then check for your graphics card’s driver. You can do this in many ways. But I suggest you go to your graphics card’s manufacturer website and look for your driver and install it. If you have already installed the driver, then it will not be necessary.

If you are a windows user, then you probably don’t need to do this manually. Just check your driver update. If you have not installed your graphics driver, it will find it for you. Then install it and restart your PC. You will feel the difference between the past and the present visual effects.

You will not face a problem with adding an external display. But if you want more than one additional displays, then it is a matter of concern because of the limitations of the graphics drivers. Nvidia, AMD or Intel don’t support the same amount of displays. For example, some graphics card support up to four additional displays. Again, you may be a laptop user. Then, you cannot add more than two additional displays because of the drivers’ limitations.

To check for your driver’s support on installing additional displays on your PC or laptop, go to your graphics card’s or laptops manufacturer’s website. You will find all the information there. But generally, you will not face any problem with installing an additional display on your PC. The limitation of the driver will be concerned when you try to install more than one additional displays.


  1. Check for the resolution.
    To connect two monitors to your PC, first, you have to get two monitors! But the question arises that do the monitors have to be same? The answer is, no. They do not need to be same. You may have fully two different monitors. But obviously, two monitors having the same configuration will give you the best viewing experience. The problem with running two different monitors is the resolution. At the time of moving programs to a monitor from another monitor, it will automatically resize the window according to its resolution. So, if you are going to use two different monitors, just make sure that both of them support same resolution.
  2. check the connections on the back of the monitors.
    It is not necessary to have multiple inputs on your monitors. But it is necessary to have two different inputs for the monitors. Suppose, one monitor has DVI input, then the other monitor needs to have either HDMI or DisplayPort, or VGA input. But if your graphics card has two same outputs, or you may have two graphics cards installed on your PC, then your monitors don’t need to have two different inputs.

Generally, most of the monitors have multiple outputs for a different connection. Nowadays, monitors generally come with three connections. They are HDMI, DVI, DisplayPort.

HDMI, DVI, DisplayPort

But cheap monitors generally have fewer connections. But it is not a problem if your monitor has the input connection compatible with the output connection of the graphics card.

Suppose, a gaming graphics card has dual DVI-D, one HDMI, and one DisplayPort. Using this graphics card, up to four monitors can be connected to one PC. So, it is easy to understand that graphics card’s output determines what types of connections you need on your monitors.

Using this graphics card, up to four monitors can be connected to one PC

Cable to Connect

Now, you know that you need different connectors for different inputs of the monitors and outputs of the graphics card. There are different connectors like DVI, HDMI or DisplayPort connectors for one monitor. You will connectors on the basis of connection of the monitors and the graphics card.

In Windows 7 or later, you will find four display modes available. You can access this by pressing Windows + P. Then you will find four options in a sidebar. They are:

  2. Duplicate: This option allows the secondary monitor to show duplicate desktop.
  3. Extend: Both the monitors are combined to act as an extended desktop.
  4. Screen Second Only: This option will use only the secondary monitor.Switch Between Display Modes

Configuring Display Settings

In this section, I’m going to talk about configuring dual monitors settings in windows 10. Because windows 7 basically has fewer features available in Windows 10.

To do that:

  1. First, right-click on the taskbar.
  2. Then, choose Settings.
  3. Scroll down and find Multiple Displays.
  4. Now, Turn off or toggle the show taskbar on all displays option.Hide the Taskbar on Displays
