What is USB?
USB stands for Universal Serial Bus, a widely used interface primarily used for connecting computers to peripheral devices. Nowadays, almost all computer peripheral devices use USB technology to communicate with computers. USB is also widely used to transfer power to various devices, including phones, tablets, etc.
The journey of USB began in 1996 with the USB version 1.0. The latest USB standard is 3.1, also known as “SuperSpeed+.” USB connectors come in various dimensions and shapes. The first USB connector was the Mini USB, while the newest standard is the USB Type-C connector.
What is Type C?
Type C is the new industry-standard connector for transferring files and power. As discussed earlier, several problems with the conventional USB connectors have been resolved. The USB-IF forum developed it. This is a group of companies that design, certify, and promote the evolution of USB protocols and connectors. The forum’s members include all the big names in the technology industry, including Dell, Apple, Intel, Microsoft, HP, Samsung, and many more.
Type C may appear to be similar to older versions at first glance, but it has a unique oval shape and is thicker. One of the exciting features of the USB Type-C connector is that it is flippable, so you don’t have to worry about getting it in the right way as you had to do with the older versions. Another remarkable feature is that it is reversible, meaning both connectors are identical, and you can use both reversibly.
What makes the USB Type C so superior is its capability. Here are some of the benefits that the combination of USB 3.1 and Type-C connectors provides you:
- Let you transfer files at a faster speed (up to 40 Gbps)
- Can charge the device quickly and power up the laptop and monitor.
- Support smooth Audio transmission.
- Some specific variations support video transmission.
What is Type-C Alt Mode?
Before getting familiar with the Type-C DP Alt Mode, you need to familiarize yourself with the Alt Mode/Modes. Alt Mode or Alternate Mode is a functional extension of the Type-C to transfer non-USB signals. It is an optional feature that the hardware manufacturers can implement in their Type C to support additional data protocols. That is, if your Type-C connector comes with a specific data protocol, you can use it without an active adapter to directly transfer or transmit the data.
As it is an optional feature, not all USB Type-C devices come with Alt Mode and additional functions. Some of the currently available Type C Alt Modes include:
- DisplayPort Alternate Mode
- ThunderBolt Alternate Mode
- VisualLink Alternate Mode
- HDMI Alternate Mode
- MHL Alternate mode
The DP Alt Mode, or DisplayPort Alternate Mode, you are using is a variation of the Type-C Alt Modes. We will discuss it more in the following paragraphs.
So, What Is DP Alt Mode?
Simply put, DP Alt Mode is an optional feature of Type C that allows the transmission of video signals. If you want to connect an external monitor to a device previously, you must use HDMI or DisplayPort adapters. However, with the introduction of DP Alt Mode, you can directly connect the device to the display using the USB-C cable without any adapters.
The DisplayPort Alt Mode integrates HDMI and DisplayPort protocols into Type C. Therefore, the device (e.g., smartphone/laptop) must be compatible with the DP Alt Mode for connectivity. For this connectivity, the display must have a Type-C port. Currently, not many devices support DP Alt Mode. However, we can expect more devices to adopt this revolutionary technology soon to provide a better experience to users.
You can still prepare the connection if the external display does not have a Type-C port and comes with traditional connectors like HDMI, VGI, or DVI. You will just need a Type-C video adapter.
What is Full Function Type C?
As discussed earlier, there are different variations of Type C, and each of them can provide you with diverse benefits. However, choosing different cables for different purposes can be confusing and costly. This is where the full-function USB Type C comes into play to resolve this problem. With the full-function or full-featured Type C cable, you can use the available features of this technology.
The full-featured USB Type-C cables can transfer files at a high speed while also transferring video, audio, and power. This means that you can enjoy all the Alt Modes and technologies of Type C simultaneously using a single cable without any additional hardware.
The full-featured USB-C cables use the USB 3.1 or USB 3.2 standard to provide all the benefits. They are electronically marked and come with a chip that contains VDM (Vendor Defined Messages). The chip contains vendor data, USB signaling protocol, hardware/firmware version, etc.
The full-featured USB 3.1 Gen 2 can transfer files at a speed of 10 Gb per second and is marked with a SuperSpeed+ logo to ensure this capability. Another exciting aspect of the full-function USB-C cable is that you can use it to connect DisplayPort, HDMI, ThunderBolt, and other alternative modes.
Conclusion
Type C is a groundbreaking technology that provides numerous benefits. However, not all Type Cs in the market are the same. And you can only enjoy the full potential if you have an appropriate cable. For example, if you want to use all the features of Type C technology, you will need a full-function Type C cable. So, for transmitting video signals, you will need a Type C with DP Alt Mode.
Finally, if you have been wondering about the DP Alt Mode and full-function USB-C cable, we hope this article helps you get an overview of them.
