Work can get overwhelming. 

You get notifications from five different apps. You have to write an email while reading a document while participating in an online meeting. 

You wish you had two heads, four brains, and at least nine eyes to be able to cope with the workload. 

Even though such improvements are impossible, you can always start by setting up dual monitors.

Yes, I know it sounds a bit underwhelming after the four brains idea!

But, anyway, let’s see how to setup dual monitors and make your life easier.

What do I Need to Start?

Before all else, make sure your video card supports a dual-screen setup. You can get this information from your card manufacturer’s website.

Best Monitors for a Dual Screen Setup

Now, what should your second monitor be? 

It's preferable to be the same model as your original screen, as there will be no difference in resolution, refresh rate, and color depth. There’s no technical issue with connecting different screen models, but it could cause some irritation.

Among the best monitors for dual monitor setup are “Dell S2722QC”,  “AMD X= XG24IPS”, and “Gigabyte M27Q,” all of which offer HD resolution, high image quality, and low input lag. 

Connectivity

You’ll also need appropriate cables. Don’t worry if your computer supports one interface and your screen another. You can buy adapters such as HDMI to VGA at a relatively low price.

You can set up dual monitors with an HDMI splitter, but it comes with setbacks. Adapters allow for the extension of one screen to another. The splitter will only duplicate the main screen to the second one.

What are the Benefits of Using Dual Monitors?

A good dual monitor setup can be a great quality of life improvement.

But how great exactly, and where is it applicable?

Academia

A study performed by the University of Utah reveals that dual monitors outperform single-monitor setups. Participants using a two-monitor setup scored higher in all categories. These include “Task Completion,” “Ease of Learning,” “Task Tracking,” and “Problem Tracking,” among others.

Streaming

Being a successful streamer is no easy job. Having a multi-monitor setup helps you keep an eye on the chat, make quick references, and manage your streaming software without crowding your screen. It also lets you keep personal communication or input sensitive data without fear of compromising your privacy.

Office Work

Dual screens are of great help, regardless of whether you’re in tech support, accounting, HR management, or any other type of white-collar job. They help you concentrate on your work while still keeping an eye on other important things. Communication, documents, lists of employees or clients – all of these could have their own designated screen, making them available at a glance.

Gaming

Having two monitors for gaming can be quite useful. You can designate one screen to the game while browsing the internet or playing music on the other. Nobody likes losing an online game just because they minimized the screen for a few seconds.

Some games are also a feast for the eyes. In such cases, more monitors equal more stunning graphics to be admired.

Wrap Up

Even though it requires some investment and technical knowledge, getting a good dual monitor setup can be of great use. It improves your work output in addition to learning, streaming, and gaming experiences. 

Don’t hesitate to give it a try. It might just end up being your thing.

FAQ.


How to setup dual monitors with HDMI?

If you have two HDMI ports, you’re in luck. All you have to do is connect the screens to them.

In case you only have one port, you’ll need to buy a USB to HDMI adapter and connect the second screen to it.

When all is connected, go to your display options and set them to your preferences.

What cables do I need to use dual monitors?

Setting up dual monitors requires cables supported by both your computer and screen. This means having VGA cables to connect to your VGA PC port and screen. The same goes for every other interface.

In case your screen supports one interface (VGA) and your computer another (HDMI), you’ll need to buy a VGA to HDMI adapter. Otherwise, it won’t be possible to pass the signal from one device to the other.

How do I get my computer to recognize a second monitor?

Your computer usually handles this process automatically. If the screen isn’t recognized, there may be a technical issue. Check if both devices are functional, if the cables are properly inserted, and if there’s visible damage on any of them.

If everything is in order, and your computer still doesn’t recognize the second screen, go to the display options. There should be a button to detect new monitors and identify them.
