Introduction
With two micro HDMI slots, the Raspberry Pi 4 Model B allows users to set up two monitors. When you connect two monitors, it helps increase productivity and facilitates multitasking.
Additionally, you can connect your Raspberry Pi to two monitors in 4K resolution and output 4K video.
These videos can go up to 30 frames per second (fps) or 60 frames per second (fps). However, you will need appropriate connectors for this.
But you must remember that this setup is easy to arrange.
So, let us look at how you can use a Raspberry Pi device to improve your workspace and productivity with two monitors!
Understanding The Raspberry Pi
The Raspberry Pi is a cheap, credit-card-sized chip. This can be connected with a regular mouse and keyboard to a TV or computer monitor. Like a PC, it has a specialized processor, memory, and graphics driver. The Python name “Raspberry” originates from the microcomputer brand name of the corporation. It is a powerful tool that enables individuals of all ages to investigate computing. Additionally, it helps you learn programming languages like Scratch and Python. The Raspberry Pi OS is a customized version of Linux. Moreover, it offers useful applications. This includes media streaming and increasing the range of Wi-Fi networks.
Things You Need For Dual Monitors Setup
Before we proceed to the steps, you must take note of the things you’ll need for this setup. Mentioned below are the materials that you will need to complete this setup:
- Two screens using HDMI or Two screens using HDMI.
- The Official Starter Kit for Raspberry Pi.
- One Model B Raspberry Pi 4.
- One SD card with Raspbian pre-installed.
- One 5.1V/3A USB-C power supply.
- Two HDMI to micro-HDMI cables.
- Just one mouse and keyboard.
- One Raspberry Pi 4 Model B official case (optional).
Steps To Set Up Dual Monitors With A Raspberry Pi 4
Given below is your step-by-step guide to ensure a good dual monitor setup with a Raspberry Pi 4 HDMI Adapter:
Step 1: Connect The Monitors
To utilize a Raspberry Pi 4 or 400, attach the micro-HDMI end of a pair of wires to an output port.
The primary display port on the Raspberry Pi 400 is HDMI0, located next to the microSD card.
However, on the Pi 4, it is HDMI0, located next to the USB-C power input.
You may use the Screen Configuration settings in Raspberry Pi OS. This will help you swap between the two displays as your primary display.
Therefore, you can configure and orient the two monitors to suit your workplace. Moreover, you can select which one you wish to use as the main display.
Lastly, ensure the monitor’s input is configured to the right HDMI input. Do this before connecting each cable’s full-size HDMI to an input on the display.
Step 2: Connect The Mouse And Keyboards
After configuring the screen settings, the next step is to connect the mouse and keyboards to the Raspberry Pi.
You can do this by plugging the USB connectors of the mouse and keyboard. Plug them into the USB ports on the Raspberry Pi.
Make sure to connect them securely. This will ensure proper functionality.
Once connected, you will be able to control and interact with the Raspberry Pi using these peripherals.
Step 3: Power The Raspberry Pi On
To turn on the Raspberry Pi, plug the power source into the board’s micro USB port.
Next, you must verify that the power source can meet the power needs of the Raspberry Pi.
The Raspberry Pi will begin to boot up once it is connected. You will see the LED lights on the board that indicate it is powered on.
Moreover, you can also use a USB-C power source. This can help charge your Raspberry Pi, and you must wait for it to boot.
Finally, you’re done if you’re viewing the boot screen. The menu is on the left, and the mouse moves fluidly between the screens!
Tadaa! You’re All Set!
The monitor mode required for packet captures and Wi-Fi scanning is not supported by the Raspberry Pi 4.
However, to turn off the Raspberry Pi, switch out the micro HDMI connections or go to “Preferences” and “Screen Configuration” in Raspbian to change the screen choices.
Connecting two monitors to a Raspberry Pi 4 or Pi 400 is a simple way to increase screen real estate.
Additionally, it can mix and match different kinds and sizes of screens.
Moreover, you can connect a single 4K monitor and run it at 4K resolution. This can run up to 60Hz to achieve 4K video output with a higher refresh rate.
