  • Thunderbolt vs. Mini DisplayPort: The Comparison Guide

Looking for a way to connect your Macbook to an external display, but not sure which port is the right one? Thunderbolt and Mini DisplayPort are two popular options that can get the job done.

Thunderbolt is a hardware interface developed by Intel and Apple that enables data transfer and video output whereas Mini DisplayPort is a digital audio and video interface that allows for high-definition video and audio transfer from a computer to a display device.

What is Thunderbolt?

Thunderbolt is a high-speed input/output technology that was developed by Intel in collaboration with Apple. It uses a special port to connect peripheral devices, such as external hard drives, displays, and docking stations, to a computer or other devices.

Thunderbolt technology combines PCIe (Peripheral Component Interconnect Express) and DisplayPort protocols to deliver fast data transfer speeds, high-quality video output, and power over a single cable.

It also supports daisy-chaining multiple devices, allowing users to connect multiple Thunderbolt-enabled devices to a single port.

What is Mini DisplayPort?

Mini DisplayPort is a digital display interface developed by Apple Inc. It is used to connect a video source, such as a computer, to a display device, such as a monitor or a projector.

Thunderbolt is a technology that combines Mini DisplayPort and PCIe (Peripheral Component Interconnect Express) into a single interface, which allows for high-speed data transfer and video output.

Advantages and disadvantages of both connectors

Thunderbolt :

  • External hard drives and SSDs
  • Docking stations
  • 4K and 5K monitors
  • Dual displays
  • Charging laptops and other devices

Mini DisplayPort:

  • Dell XPS, Latitude, and Precision laptops
  • Some business laptops
  • Apple MacBook, iMac, and Mac mini computers

Connector compatibility

The most common type is the Mini DisplayPort 1.2, which is found on most modern laptops and PCs. However, there are also older versions of the Mini DisplayPort, such as the Mini DisplayPort 1.1 and 1.0. These older versions are not compatible with Thunderbolt.

If you’re not sure which type of Mini DisplayPort connector you have, you can usually find out by looking at the specs of your laptop or PC. If it’s not listed there, you can also try checking the manufacturer’s website.

If you have a Mini DisplayPort 1.2 connector, there’s a very good chance that it will work with Thunderbolt. On the other hand, if you have older Mini DisplayPort 1.0 or 1.1 connectors, there’s a much lower chance of compatibility.

Tips for choosing the right connection type

  • Consider what devices you need to connect. Thunderbolt can support up to two 4K displays or one 5K display, while Mini DisplayPort can only support up to one 4K display.
  • If you need to connect more than two devices, Thunderbolt is the way to go. It supports up to 40 Gbps of data transfer, whereas Mini DisplayPort only supports up to 10 Gbps.
  • Thunderbolt also supports charging and can provide up to 100W of power, whereas Mini DisplayPort cannot charge devices.
  • If you need the fastest possible data transfer speeds, Thunderbolt is the clear choice with its support for 40 Gbps. However, if you don’t need such high speeds and are only connecting a few devices, Mini DisplayPort may be sufficient.

Key differences between Thunderbolt and Mini DisplayPort

Thunderbolt offers significantly higher data transfer speeds than Mini DisplayPort.

Thunderbolt can be used to connect multiple devices together and supports daisy chaining, while Mini DisplayPort does not.

Differences between thunderbolt vs mini display port


Thunderbolt and Mini DisplayPort are two powerful and versatile connectivity standards that have greatly enhanced the way we connect and display content across devices. With their high data transfer speeds and ability to support multiple types of data and display formats, these standards have become indispensable in modern computing and multimedia applications. As technology continues to evolve, Thunderbolt and Mini DisplayPort are likely to remain key technologies for seamless connectivity and multimedia experiences.
