Check Your Computer’s Capabilities

The first step is verifying that your computer system can support a multiple display configuration. There are two key factors to check:

Graphics Card – Most modern desktop and laptop computers include graphics cards or processors with integrated graphics that allow two or more monitors to be used. Discrete graphics cards tend to have better performance for gaming or graphic-intensive tasks.

Available Ports – You will need open ports to plug the monitors into your computer. Common ports include HDMI, DisplayPort, DVI, and VGA. Some adapters may be needed depending on your setup.

Here’s how you can check both of these:

Determine Graphics Card Support

To check your graphics card support:

  • Windows – Go to Control Panel > Display > Screen Resolution. If multiple displays are supported, you will see options to extend or duplicate the desktop across screens.
  • macOS – Click the Apple menu > About This Mac > Support. Look at the number of displays supported.
  • You can also check your graphics card specs or manual for multiple display support.

NVIDIA GeForce GTX 10804
AMD Radeon RX 5804
Intel HD 40003

Identify Available Ports

Next, inspect the back of your desktop or sides of your laptop to locate available ports. Take note of the quantity and types of ports.

Common port types:

  • HDMI – Supports up to 4K resolution. Most common and convenient display connection.
  • DisplayPort – Provides high resolutions and refresh rates. Found on many modern graphics cards.
  • DVI – Supports up to 1080p resolution. Found on older graphics cards.
  • VGA – Lower resolution analog connection. Used for legacy monitors.

Note the types of ports available to determine required adapters and cables later.

You may need to use adapters like HDMI-to-DVI or DisplayPort-to-VGA to connect certain monitors if there is a port mismatch.

By checking graphics card support and available ports, you can determine if your computer system can handle dual displays. If you have the proper graphics capability and open ports, you’re ready to move on to selecting monitors!

Choose Your Monitors

Once you’ve verified dual monitor compatibility, the next step is choosing one or two monitors to add to your workspace. Key factors to consider are:

  • Monitor size – Standard options include 22″, 24″, 27″ and ultra-wide monitors 34″ or larger. The size impacts desk space and viewing comfort.
  • Resolution – Minimum 1920 x 1080 (1080p) recommended. Higher resolutions like 2560 x 1440 (1440p) or 3840 x 2160 (4K) provide more screen real estate.
  • Refresh rate – Standard is 60Hz but rates up to 144Hz provide a smoother experience especially for gaming.
  • Aspect ratio – Most monitors are widescreen 16:9. Ultra-wide models are 21:9. Match your primary monitor for consistency.
  • Connectivity – Look for monitors with HDMI, DisplayPort or other ports that match your computer.
  • Adjustability – Height, tilt, swivel and rotation adjustments provide ergonomic benefits.

Here are some monitor recommendations for different budgets and needs:

Dell U4919DW49 in5120 x 1440Ultra-wide curved screen, USB-C connectivity$929.99

Ideally, choose two monitors that match in size, resolution, and physical appearance for a seamless dual-monitor setup. If your budget allows, investing in monitors with thin bezels can help minimize borders between the two displays.

Purchase Necessary Cables and Adapters

Once you’ve selected compatible monitors, the next step is purchasing any required cables, adapters or hubs to connect them. Consider the following when obtaining cables:

  • Cable type – HDMI, DisplayPort, DVI and VGA cables are common. Try to match computer and monitor ports when possible.
  • Cable length – Longer cables allow more setup flexibility but may degrade signal. 3-6 feet is recommended for most desks.
  • Adapter needs – DisplayPort-to-HDMI, DVI-to-VGA, or USB-C-to-DisplayPort adapters allow port mismatch connections.
  • Quantity – You need one cable for each monitor. Daisy-chaining via DisplayPort Multi-Stream Transport (MST) only requires one cable.
  • Quality – Don’t skimp on cheap cables that can degrade performance and reliability. Spending a bit more on quality cables is worth it.

For example, if your monitors support HDMI and your computer has one HDMI port and one DisplayPort, you would need:

  • 1 x HDMI cable
  • 1 x DisplayPort to HDMI adapter

This allows both monitors to connect. Having the proper cables and adapters on hand before connecting simplifies the process.

Connect the Monitors to Your Computer

With compatible monitors and cables in hand, it’s time to physically connect the displays to your computer. Follow these best practices when connecting:

1. Connect the Primary Monitor

  • Connect the other end of the cable to the corresponding video input port on the rear of the monitor.
  • Power on the monitor and ensure an image appears properly. This will serve as your main display.

2. Connect the Second Monitor

  • Identify an open video port on your PC to use for the second display.
  • Use the appropriate cable or adapter to connect this port to the input port on the back of the second monitor.
  • Power on the second monitor. An image may not show up yet until display settings are configured in the next step.
  • For video cards that support daisy-chaining, connect both monitors to each other via DisplayPort MST using a single cable.

Some best practices when running cables:

  • Neatly route and organize cables to minimize clutter.
  • Don’t bend cables sharply.
  • Use cable ties or sleeves to bundle related wires.
  • Connect monitors before powering them on to avoid issues.
