In the ProAV industry, products like the KVM switch and KVM extender that would support dual display have gained popularity in the market. Dual monitor setup is not a new thing and some users may have moved on to even more screens.

If a second monitor does increase your efficiency and experience, why limit yourself to just one? Let’s see why people use a dual monitor setup and what’s the easy way to build one.

Why You Need Dual Monitors?

The advantage of using dual monitors is obvious – you will be able to refer to more resources simultaneously. If you have to refer to multiple sources at the same time, even a 24-inch iMac screen could be cramped, let alone a laptop screen. Adding an extra screen could solve this problem.

With a second display, there will be more room to roll out staffs and resources ready for direct use or constant monitoring. Professionals like video editors and coders need a second monitor to preview the project they are working on; Youtubers may use a second monitor to check the streaming image. Here are the benefits:

  • Extra viewing room to roll out more resources
  • No more clicking through multiple tabs or apps
  • Monitor your content simultaneously
  • Streamline your tasks and maximize your productivity

4 Things to Consider Before Setting Up Dual Monitors

Here are a few things to consider when you decide to get yourself a dual monitor setup.

  • Number of PCs
  • Graphic card
  • Connector type
  • Display

Number of PCs

Dual monitors are used for display. The question is how many PCs or laptops are you connecting to them? If you wanna connect dual monitors (and a keyboard and mouse) to two servers, you would need a dual monitor KVM switch like this. 

With a KVM switch, you can easily control your PCs with the same keyboard, mouse, and two monitors, instead of crowding your desk by doubling things up.

Since you are using two monitors at a time, you will be switching from here and there, watching both of them. Having your monitors lined up with the same or similar settings is critical. 

A gap in color, lightness, or resolution could easily exhaust your eyes and harm your sight. Therefore, if the two monitors are the same model of the same make, it would be easier to put them in sync. 

Graphic card

Not all PCs are designed for multiple displays. If your graphic card is not competent enough, connecting to an extra display may bring down the image quality or it just fails to present two views at the same time.

Make sure your PC or the graphic card you are purchasing supports dual monitors at the needed resolution & refresh rate. That would be essential if you are playing UHD serious games.

Connector type

Most displays support HDMI, DisplayPort, or Type-C connection, sometimes VGA or DVI. Check the ports on your computer and make sure which type of connectors you will be using.

What if there is only one HDMI port on your laptop and you wanna connect it to two monitors? You may try an HDMI splitter only if it would be OK to have just a mirroring screen. Or you need to utilize an HDMI with another connector type like DP and type-C.


Leveling up the hardware is a way to boost our productivity and it’s always a pleasing thing to do. If you are a dual monitor user already, the next step may be to make it even more comfortable and ergonomic.
