Most modern laptops can connect to an external monitor, projector, or TV. The connection method depends on the type of port the laptop has and the monitor’s input capabilities.
For example, a Windows laptop may use HDMI or USB while MacBooks may use Thunderbolt or USB. You may also need an adapter.

Power How to Connect a Laptop to a Monitor HP:
Using a monitor with your laptop gives you more screen real estate, making it easier to work and avoid having to toggle between windows.
This is ideal for a wide range of scenarios, from leisure activities like video chatting to navigating an Excel spreadsheet.
If your laptop has HDMI or DisplayPort output ports, the process is easy enough to get it connected to an external monitor.
You need to connect one end of a HDMI or DisplayPort cable to your laptop’s output port, and the other end to the external monitor.
The system will automatically detect the connection, and you can choose whether to duplicate or extend the desktop on the second monitor.
You can also adjust the arrangement of displays from the Display Settings window on Windows, or System Preferences on Mac.
HDMI cable connections are common for laptops and monitors because they transmit audio and video signals in one wire. You can connect a second monitor using an HDMI-to-HDMI adapter that has a dual-monitor output.
You can also use a USB-C port on newer, slim laptops that support DisplayPort Alternate Mode and HDMI transfer. Some laptops include a separate HDMI port, while others have HDMI ports built into the motherboards.
In Windows, click the “Display” icon to open a Display window. You will see two rectangles on the screen-one representing your built-in laptop screen and the other representing the external monitor.
Click the “Duplicate these displays” button to mirror your laptop’s screen on the external monitor or choose “Extend these displays” to extend the desktop so that you can drag windows from one screen to the other.
A monitor can be connected to a laptop with an HDMI, DisplayPort, or DVI cable. These are the most common connector types found on modern laptops and monitors.
Older laptops might have a VGA port for connecting to a second screen, but these only support standard definition (640 x 480) or high definition (up to 1920 x 1080).
HDMI and DisplayPort are more convenient since they transmit audio and video signals over a single cable. Some laptops have a USB-C port that can function as a DisplayPort interface as well.
Connecting to a monitor via these ports allows you to duplicate or extend the laptop’s desktop on the additional display. Once the monitor is connected, Windows should automatically identify it and configure its settings.
If you have an older laptop that doesn’t have HDMI or DisplayPort, it’s still possible to connect a monitor HP using a VGA cable. The connection requires an adapter that converts the video signal from the laptop to the VGA input on the monitor.
Connect the cables, turn on the monitor and laptop, and wait for Windows to detect them. Once they’re connected, you can choose how Windows will use the two displays (duplicate these displays; extend desktop) from the laptop’s display settings menu.
With more screen real estate, you can work without having to shrink windows or toggle between programs.
You can also drag a window from one monitor to the other, which can be especially useful when using multiple applications for business or leisure.
The easiest way to connect a laptop to an external monitor is with HDMI. Most modern laptops have HDMI ports and most modern monitors support HDMI.
To use an external monitor with a laptop, simply attach one end of the cable to the laptop and the other to the screen.
Then select the external monitor as the primary display in your laptop’s or computer’s Display Settings window (on Windows) or System Preferences on Mac.
You may be prompted to press an activation key on the laptop keyboard to activate the external display.
You can also connect to a monitor using a DisplayPort (DP) cable. DP looks like HDMI but is flat on both sides instead of slanted on the top. DP and HDMI both carry audio so you can send the laptop’s sound to the monitor.
