Difference Between Thunderbolt and Mini DisplayPort (With Table)

When it comes to computers, there are all kinds of connectivity options that can be seen whether physical or wireless. Both the desktops and laptops required connectors for external devices connection. Many of the parts are not vital but video ports are necessary because a computer cannot be used without a monitor.  

Laptops have a thin form factor and that’s why they offer ports like Thunderbolt and DisplayPort for video output. They both have great running high-performance displays. To pick the right one, it is necessary to know the difference. 

Thunderbolt vs Mini DisplayPort  

The main difference between Thunderbolt and Mini DisplayPort is that   Thunderbolt requires a Thunderbolt monitor or an adapter to connect with other kinds of a monitor. On the other hand, Mini DisplayPort can be used in any monitor with a connector of display port. Thunderbolt can support dual 4K 60HZ monitors or more, while Mini DisplayPort can support up to 2560 X 1600 monitors.  

Thunderbolt is a technology of 1/0 which helps to combine fast transmission rates for audio, video streams, and data into one interface. Intel Corporation was the developer of Thunderbolt and in February 2011, Apple’s MacBook Pro was the first to use it. Light Peak was the original code name of Thunderbolt.  

Mini DisplayPort is a version of the interface of display port which was introduced in October 2008 and designed by apple. It uses a smaller socket and plug as compared to the full-size display port. The Mini DisplayPort or simply Mini DP was the foundation for the interface of Thunderbolt. It is also used on some Windows PCs.

What is Thunderbolt? 

Thunderbolt is a high-speed interface of 1/0 which is based on display port and PCI Express technologies. It supports both displays and data devices. Thunderbolt was developed by Intel and Apple was the introducer in 2011. Due to the architecture of the PCI Express, it can now achieve performance that was previously possible only from internal components.  

Thunderbolt interface provides 10 Gpbs throughout in both directions. This means that it is 20 times as fast as USB 2.0 and 12 times faster than FireWire 800. FireWire 800 Interface supports only one 720p video stream but the Thunderbolt interface can provide 8 simultaneous streams of 720p video.  

Like FireWire and USB, Thunderbolt offers power to connect peripheral devices. It means that external devices with the requirement of 10 watts or less of power can be directly powered from this port. To connect Thunderbolt, simple adapters can be used like FireWire, Ethernet, and USB.  

Although, Thunderbolt is used as an interface of high-speed data but also be used to connect displays with high resolution. Thunderbolt interface can also be used to connect a monitor of the display port. Due to its being physically identical to the interface of Mini DisplayPort. 

What is Mini DisplayPort? 

The Mini DisplayPort or simply Mini DP or mDP is a less common or miniaturized version of the full-size display port. In October 2008, it was announced by Apple, and by early 2013, this port was available on all new Apple Macintosh computers. In 2016, Apple started phasing out this port and started using USB- C connector.  

The Mini DisplayPort can also be fitted to some video cards, PC motherboards, and some PC notebooks from Microsoft, Lenovo, HP, Asus, Dell, Toshiba, and other manufacturers. For the Mini DisplayPort, a free license is offered by Apple. But the right to cancel the license is also reserved by Apple.   

Mini DisplayPort provides better performance compared to video ports like HDMI, DVI- D, and others. The resolution screen can be up to 2560 X 1600 which is for the average user Is decent enough. If you are looking for 4K or 5K displays then it is not meant for you.  

DVI port was replaced by the Apple from the Mac Mini, Mac Pro, MacBook, MacBook Pro, and MacBook Air with the Mini DisplayPort. It is a general connector for high compatibility with the displays of all display ports. But it fails to work with multi-display adapters. 

Main Differences Between Thunderbolt and Mini DisplayPort 

  1. Thunderbolt can be identified with a lightning bolt logo located on the port. On the flip side, Mini DisplayPort comes with a rectangle logo located on the port with mainly two vertical bars.  
  2. Thunderbolt can be connected to adapters, docks, hubs, eGPUs, monitors, and more, whereas Mini DisplayPort can only connect to TVs or monitors with supported video ports.  
  3. When it comes to connectivity of the ports, Thunderbolt uses a connector of USB type C which allows connecting all kinds of devices to it, while a proprietary connector is used with Mini DisplayPort.  
  4. Thunderbolt works as a USB, eGPU connector, ethernet, video output, and more with adapters. On the other hand, Mini DisplayPort works only as a video output port.  
  5. In terms of compatibility, Thunderbolt requires a Thunderbolt monitor or an adapter to connect with other kinds of monitors. But Mini DisplayPort can be used in any monitor with a connector of display port. 


It can be concluded that both Thunderbolt and Mini DisplayPort are working as a connector for video output. Now it is easy to pick the right one for video output. They both have great running performance displays and that’s why these ports are preferred by most users.  

Functions of Thunderbolt are much more versatile. On the other hand, Mini DisplayPort Is better to use when all you need is a video output port without the need for an adapter. A lightning bolt logo is located on the port of Thunderbolt, whereas a rectangle logo is located on the port with two vertical bars on Mini DisplayPort.
