How to connect a second screen to a laptop

 A laptop screen may not be enough when working from home. Fortunately, most devices are easy to expand the workspace, even if they don't have a connector for a second display. Consider options that do not require buying a lot of additional equipment.


Using the connector for the external display

Many laptops have a port for connecting a second monitor. It may look like a regular connector, such as HDMI, but is usually smaller. If one of the ports seems unfamiliar, it may be used to connect the display.

Macbooks and some laptops on the Windows platform have Thunderbolt, Mini DisplayPort, and Mini-DVI ports. You will need a special adapter or cable to connect an external monitor. For example, Microsoft's Surface Book laptop has a built-in Mini DisplayPort, which with the help of an adapter can be converted into ordinary HDMI, suitable for connection to almost any TV or monitor.

Using a USB port

If there is no special connector for the display, you can use a USB connection. For example, USB-C is suitable not only for connecting external hard drives and phones but also for monitors. In most cases, you will only need a cable.

If the laptop does not have USB-C, then more familiar USB ports will do. With external hubs, you can not only increase their number but also connect the display via HDMI and even add an Ethernet connection. This method will be especially useful when there are not enough ports to connect all the peripherals that were used while working in the office. However, not all laptops support USB-C video output, and only a few foreign keys can add support for this feature, so be sure to read the manufacturer's instructions for the specific device.

Adapting the tablet as a monitor

The tablet can also act as an additional monitor of a smaller size. The Mac operating system is equipped with Sidecar technology to connect the iPad via USB-C or Lightning cable.

Achieve the same result with products from different manufacturers will help third-party applications. The most reliable option is the DuetDisplay program, which allows you to connect Android / iOS tablets to Mac / Windows devices.

By connecting the monitor directly to the laptop

Some monitors are specifically designed for use as optional displays. For example, Duex Pro, which can be attached to the back of the laptop screen and extended if necessary. This is a convenient option that does not take up much space and, most importantly, convenient for travel.

In addition, there are portable displays designed to work from a single connection (do not require a separate power supply). They can be stored in a laptop bag and used as needed.

Transferring some tasks to the phone

Some work tasks can be transferred to a phone or tablet without connecting an additional monitor. You can mount the phone on a stand or wireless charging.

For example, you can check your mail from your phone by switching to your Inbox if necessary. The phone is also suitable for tracking Slack chats, news, dashboards, and other metrics without cluttering the main desktop.
