Check out the Detail information about HDMI and thunderbolt and some major difference between HDMI and thunderbolt.
1)What is a thunderbolt
Thunderbolt is a high-speed I/O interface created by Intel and released by Apple in 2011. It is based on PCI Express and DisplayPort technologies and supports both data and display devices.
Since Thunderbolt is based on the PCI Express architecture, external devices connected via Thunderbolt can achieve output that was previously possible only from internal components. In addition, the Thunderbolt interface provides 10 Gpb of throughput in both directions. That’s more than 12 times faster than Firewire 800 and more than 20 times faster than USB 2.0. While the FireWire 800 interface can only support one 720p video stream, the Thunderbolt interface can support 8 720p video streams simultaneously.
Like USB and FireWire, Thunderbolt will supply power to connected peripheral devices. This means that external devices needing 10 watts of power or less can be operated directly from the Thunderbolt port. In addition, simple adapters can be used to connect USB, FireWire, and Ethernet devices to a Thunderbolt port.
While Thunderbolt is primarily used as a high-speed data interface, it can also be used to link high-resolution displays. The Thunderbolt interface is physically similar to the Mini-DisplayPort interface and can therefore be used to connect the DisplayPort monitor. Like HDMI, DisplayPort supports audio and video, removing the need for a separate audio cable.
Thunderbolt devices can be daisy-chained, which ensures that multiple devices can be attached to a single Thunderbolt port in sequence. For example, you can connect the Thunderbolt display to your computer and the Thunderbolt external hard drive to your display. You can also attach a second Thunderbolt monitor to the first display. This means that you can attach two external displays to a laptop as long as the laptop supports the resolution needed for two screens.
2) What is HDMI
HDMI stands for “High-Definition Multimedia Interface.” HDMI is a trademark and brand name for a wireless interface used to transfer audio and video data in a single cable. It supports current audio/visual devices such as 4K televisions, HDTVs, audio receivers, DVD and Blu-ray players, cable boxes and video game consoles.
While other forms of A/V connections include separate audio and video data cables, a single HDMI cable links audio and video streams, reducing cable clutter. For example, an analog cable link requires three video cables and two audio cables, with a total of five cables. The same details can be transmitted digitally using a single HDMI cable.
Since HDMI is a wireless link, HDMI cables are less vulnerable to interference and signal noise than analog cables. Furthermore, as most components, such as DVD players and digital cable boxes, process information digitally, HDMI removes the need for digital-to-analog and analog-to-digital conversion of other interfaces. HDMI therefore usually provides the highest image and sound quality compared to other forms of connections.
HDMI cables are also more costly than analog cables because they are more expensive to produce. However, it is important to note that multiple analog cables can be replaced by a single HDMI cable. The single all-purpose connection simplifies the configuration and makes it easy to attach and detach devices. It also supports digital commands, enabling devices to communicate with each other. For example, if your TV is connected to the receiver via HDMI, the TV will automatically turn the receiver on and off when the TV is switched on and off. The volume between the TV and the receiver can also be synchronized. Modern HDMI receivers allow you to visually customize the settings of the receiver using your TV as an interface.
NOTE: HDMI is a trademark held by HDMI Licensing Administrator, Inc. (HDMI LA) that serves as a source identifier for the HDMI LA brand of digital interfaces used to connect high-definition devices.
IS thunderbolt better than HDMI
HDMI is the standard for linking high definition video devices. Today, most televisions are fitted with at least one HDMI port. When it comes to connecting your laptop to your computer or TV, HDMI is the chosen form of link capable of transmitting high-definition audio and video over a single cable. Simply put, HDMI integrates audio and video into a single digital platform for use in video game consoles, Blu-ray players, HDTVs, audio receivers, etc. HDMI ports can be found in almost any consumer electronic product, including HDTVs, DVRs, music players, etc.
Thunderbolt is the latest in peripheral networking and high-speed connectivity technology that supports both data and HD display data on a single cable. It’s the latest and fastest connection type yet, perfect for connecting an external display or monitor or external hard drive to your device. Similar to USB, it is plug-and-play but allows several devices to be connected together. Connecting some Mac devices using the Thunderbolt port is a better alternative to using a FireWire link. Thunderbolt is considerably faster than USB 3.0 or FireWire and has more bandwidth of video than HDMI. Let’s see how the two display interfaces stand up to each other and which one is better off.
