The dual monitor setup is, yes, no points for guessing right, two displays connected to your desktop or laptop. You can use HDMI or DisplayPort to connect the additional monitors. You can expand your screen access to work and play both. You can either mix and match screens or mount two identical ones together for an UltraWide seamless display.

If you are a programmer, go to screens that can be set up vertically to save desk space and view multiple lines of code. You can daisy chain your setup for simplification.

In layman’s terms, use a single wire to combine various displays, as in one monitor connected to another. Both will send signals to your PC and you will only have to worry about one wire.

The only issue is you will need monitors with DisplayPort 1.2 connection and Multi-Stream Transport technology for the daisy chain to work.

You also have to consider space for your monitors. You can easily put up both if you have enough space on your desk. If not, it can get overcrowded. In such cases, consider monitoring stand and wall mounting options. To manage the wiring, you can use a USB C-hub.

However, before getting into how to set up dual monitors, ask yourself if you really need two monitors. Or will an UltraWide monitor be a better choice?

Ultrawide monitors offer a lot of horizontal screen space for heavy multitasking. Also, they are comparatively inexpensive, have a seamless screen, and involve less setup.

Nevertheless, you can’t ignore the fact that with dual monitors comes a high level of versatility. You can mix and match the displays and this gives you the freedom to use a high-end 4K monitor as the primary screen while using a cheaper one for browsing and work calls.

The positioning can be flexible as well. If money and space are not any constraints to you, you can go for two UltraWide displays and have the best of both worlds at your fingertips.

  • Resolution: If you want, you can have monitors of different resolutions, but it’s not a good idea. The 1080p screen will look very low-resolution alongside the 4K monitor. It will be better if you pick the monitors for the same resolution for your setup.

  • Simple to use: They make work easy, giving you access to multiple documents at the same time, access to multiple windows without juggling, easy drag and drop of documents from one screen to another, and so on.
  • Works well with laptops: These setups are usually compatible with laptops and mobile devices as well. You can use a docking station to cast your device to a bigger screen or use it for work.
  • Decluttering desktop: Needless to say, you get double the desktop space allowing you to declutter and organize each desktop.
