How do I connect a laptop to a monitor?

If you want to connect a computer to a monitor, you often have quite a few choices to make. Your laptop or PC probably has a number of ports to choose from, and so does your monitor. What cable will you use to connect them? In this article, you'll read the best way to connect a laptop or PC to a monitor.

Settings

After connecting, choose in the settings menu of Windows or MacOS to use your monitor in one of these three ways: duplicate your laptop screen, expand your laptop screen or use only your monitor:

  • Duplicate/duplicate: both screens show the image of the laptop.
  • Extend/expand: The image of your laptop is expanded on the monitor.
  • Show only/Only 1 or 2: Display the image only on your laptop or your monitor.

At the top of the screen settings menu (in MacOS under 'arrangement') you can determine where your monitor is located in relation to your laptop. You do this by simply dragging the blue box of your screen to the left or to the right.

1 of the connectors is a VGA port

VGA

A VGA connector only transmits a video signal. To also send the audio signal, you'll need an extra cable. Since VGA is a so-called analog connector, there will always be some signal loss. In other words: the image won't look as good. The maximum resolution a VGA connector can transmit depends on the cable, among other things, but the image quality will always be lower than the one produced by 1 of the other ports.

  • Can transmit high resolution
  • Doesn't transmit audio signal
  • Lower image quality

Which cable?

The VGA cable's quality partly determines the quality of the transmitted signal. If you need a cable with 2 different connectors, please check out our cable converter page.

1 of the connectors is a DVI connector

Different DVI connections.

A DVI connector only transmits a video signal. As with a VGA port, you'll need an extra cable to transmit the audio signal. The difficult thing with DVI is that there are 5 different types. All the different DVI connectors are listed below, with the maximum resolution they can transmit at a certain frequency.

  • DVI-A: Analog connector that supports lower resolutions (1920x1200 at 60Hz)

  • DVI-I (single link): Digital and analog connector that supports lower resolutions (1920x1200 at 60Hz)

  • DVI-I (dual link): Digital and analog connector that supports higher resolutions (2560x1600 at 60Hz)

  • DVI-D (single link): Digital connector that supports lower resolutions (1920x1200 at 60Hz)

  • DVI-D (dual link): Digital connector that supports higher resolutions (2560x1600 at 60Hz)

  • Better image quality than VGA

  • Doesn't transmit audio signal

  • Not suitable for high resolutions

Which cable?

In your search for a good DVI cable, it's especially important to get a cable with the right DVI connector. If you need a cable with 2 different connectors, please check out our cable converter page.

1 of the connectors is an HDMI connector

HDMI connection image.

With an HDMI connector, you can transmit images at a 4K resolution (3840x2160). There are 2 different types of HDMI: 1.4 and 2.0. With HDMI 1.4, you can send a maximum of 4K at 30Hz. With HDMI 2.0, it's 60Hz. There's also HDMI 2.0a. This version supports High Dynamic Range (HDR) in 4K resolution at 60Hz. A 60Hz frequency means that the image is refreshed 60 times per second. For gaming, 60Hz also means that you can play games at a maximum of 60 frames per second.

  • Supports 4K resolution
  • No more than 60Hz for 4K

Which cable?

For cables shorter than 7.5 meters, there's virtually no difference between the various HDMI cables. Do you need a longer HDMI cable? Make sure to get a high-quality cable, otherwise it'll create image effects like stars, or you'll lose the signal. If you need a cable with 2 different connectors, please check out our cable converter page.

1 of the connectors is a DisplayPort connector

DisplayPort supports high resolutions at a high frequency. This makes this connector perfect for gaming on a second screen, for example. There are 3 types of DisplayPort connectors:

DisplayPort 1.2: supports resolutions up to 3840x2160 (4K) at a 60Hz refresh rate, or 60 frames per second.

DisplayPort 1.3: supports 3840x2160 (4K) resolution at a 120Hz refresh rate, or 120 frames per second. Also supports 7680x4320 (8K) resolution, but only at a 30Hz refresh rate, or 30 frames per second.

DisplayPort 1.4: supports resolutions up to 7680x4320 (8K) with a 60Hz refresh rate, or 60 frames per second.

  • Supports up to 8K resolution
  • Reaches high frequency, even at high resolution

MiniDisplayPort

MiniDisplayPort is a smaller version of DisplayPort. It uses its own connector, so you connect it with a separate MiniDisplayPort cable. In particular, MacBooks and other laptops produced before 2016 have this connector. At most, MiniDisplayPort can support DisplayPort 1.2 at a 4K resolution and 60Hz.

Which cable?

Every DisplayPort cable has the same functionality, so you don't have to look for a particular version. That is, unless you're transmitting an 8K resolution or want to display more than 60Hz. If you need a cable with 2 different connectors, please check out our cable converter page.

1 of the connectors is a USB-C connector

USB-C connection image.

USB-C is a universal connector used to transmit video and audio. USB-C is a special type of cable, as it can transmit the same video signal as DisplayPort, but through the USB-C connector instead of a DisplayPort cable. This is called DisplayPort Alt Mode.

DisplayPort Alt Mode

With DisplayPort Alt Mode, the maximum video signal you can send is at an 8K resolution at 60Hz, or 60 frames per second.

Which cable?

There are many different USB-C cables, some of which don't have enough bandwidth to transmit video and audio. Before purchasing a USB-C cable, make sure to check whether it supports DisplayPort Alt Mode. Does your laptop or PC have a USB-C connector? Make sure to also check whether the USB-C port supports DisplayPort Alt Mode.

Step 2: Connect your monitor

Now that you have the right cables, it's time to physically connect the monitor to your computer. This is how you do it:

  1. Connect the power cord to the monitor and the power socket.

  2. Connect the video cable to the monitor, then connect it to the computer. If you're using a VGA or DVI cable, make sure to also connect an audio cable if you want to use your monitor's speakers.

Would you rather connect the monitor to a desktop? Read our advice here:

Step 3: Check whether your screen is set to the right port

Using the physical buttons on the side or back of your monitor, you'll enter a menu. This menu is known as the on-screen display (OSD). Select 'input source' to change the connected cable types (HDMI, DVI, DisplayPort, or VGA).

Now that you've connected your screen, it's ready for use.
