In this guide, I’ll teach you how to use HDMI & VGA on your PC at the same time for dual monitors.

Let’s dive in!

Two Requirements

If you’re interested in setting up dual monitors on your computer using HDMI and VGA at the same time, it’s important to check two key requirements.

1. Check if Your PC’s Graphics Card Supports Both HDMI and VGA Connections

First, make sure your PC’s graphics card can handle both HDMI and VGA connections.

You can easily do this by looking at the back of your PC case, where the graphics card is located. 

There, you’ll find different connection ports. 

The HDMI port is easy to spot because it’s rectangular and clearly marked with “HDMI.” 

The VGA port is usually blue, has a symbol that looks like a small monitor, or might be labeled “VGA”.

2. Ensure Your PC’s Motherboard Supports a Dual-Monitor Setup

Secondly, it’s crucial to confirm that your PC’s motherboard is compatible with a dual-monitor setup. 

A quick way to check this is by going to your PC’s Display settings.

If there’s an option for Multiple Displays, then your system is likely ready for dual monitors.

For a more thorough check, you can research your motherboard’s specifications online. 

Start by identifying your motherboard’s model name. 

You can find this information in the System Information section of your PC, under the BaseBoard Product line.

When I checked my motherboard on the manufacturer’s website, I learned that it supports Dual Display mode, which might also be called Multi-Display or Multi-Monitor in different terminologies.

By carefully following these steps to check your PC’s graphics card and motherboard capabilities, you can confidently set up your dual monitors using HDMI and VGA, enhancing your computer’s display functionality and your overall computing experience.

Setting up dual monitors using HDMI and VGA connections on your PC can be a great way to enhance your productivity and entertainment experience.

Let me guide you through this process with a step-by-step approach.

For my setup, I’ll be using a CM2406H FHD monitor with an HDMI connection as the main display and a Samsung S19C170B HD monitor for the VGA connection as my secondary display.

Here’s how to do it:

Step 1: Connect the main monitor to your PC using an HDMI cable.

Additionally, you have the flexibility to customize each monitor’s display. 

You can tweak the resolution and orientation, or even adjust the size scaling of text and apps on each screen according to your preference.

If you wish to rearrange the layout of your screens in the dual monitor setup, that’s also an option available in the same settings menu.
