Many of the newest smartphones, tablets, and computers in your workplace have something unusual. Oblong connectors have replaced Type-A USB ports instead of the typical rectangular ones. In the workplace, in school, and at home, USB-C has taken over. In this post, I’ll describe Do All USB-C Cables Support Video?

The USB-C port is now standard on most computers, mobile devices, and tablets, replacing Apple’s proprietary Lightning connector in many versions. Even the most recent MacBooks and Chromebooks are part of the USB-C revolution.

Do All USB-C Cables Support Video?

The data transfer, charging, and video ports will all be replaced by the USB Type-C connector. But not every cable offers the same features.

As their popularity grows, USB Type-C connectors are projected to become the new standard for device-to-device interaction. However, there are no hard numbers on sales yet. Data rates of up to 10Gbps and 100W of power are expected from USB Type-C cables.

In addition to reversible plug orientation and cable direction, the Type-C connector can carry both power and data and support a variety of protocols such as DisplayPort, MHL, and Thunderbolt concurrently. Using a USB Type-C connection on a laptop can replace various other connectors. Apple’s new MacBook has a single USB Type-C port, which is used for the following:

  • Charging
  • Native DisplayPort 1.2 video output
  • HDMI video output using USB-C Digital AV Multiport Adapter (sold separately)
  • USB 3.1 Gen 1 (up to 5 Gbps)
  • VGA output using USB-C VGA Multiport Adapter (sold separately)

However, even though USB-C is an excellent concept, many low-cost USB cables can only transmit data and deliver roughly 10Wh of power. Battery capacity for laptops like the new MacBook and Google Chromebook Pixel 2 is 29Wh.

The connection quality isn’t critical for USB 3.1 data transfers and basic VGA output; it’s a concern for charging and high-definition HDMI and DisplayPort video output. The power requirements are significantly higher.

Many Apple consumers are hesitant to spend the money necessary to purchase branded accessories for their cherished gadgets because of the high cost of products like headphones and basic cords. It’s natural for many individuals to assume that any USB Type-C cable will work as a substitute for their Macbook’s original.

Is It Possible To Send Video From A Laptop Over USB-C?

There are several norms at play in this situation. One of these is USB Type-C, a brand-new, all-purpose USB connector. This is a USB connector, as its name implies. USB data transfers are guaranteed to work with any Type-C connector. Moreover, it is legal for a Type-C connection to solely support USB 2.0, even though USB 3.1 is significantly more widespread.

USB Type-C can potentially be used in a variety of other ways. In other words, technology exists to replace USB communications with electrically comparable high-speed digital signals instead of using USB signals directly. When a Type-C to DisplayPort connection is used, any laptop that supports DisplayPort as an additional mode will be able to switch to DisplayPort mode when connected.

Alternate modes are defined in the USB specification. Although the additional modes aren’t, the selectable modes are determined by the specifics of your laptop’s system rather than by the Type-C standard. What, if a laptop’s designers support any, Type-C additional modes is entirely up to them.

It’s possible to identify several alternate modes. Type-C ports can be seen on this Dell laptop, for example. There are two Thunderbolt 3 ports on the left (the other one, presumably, does not) and one Thunderbolt 3 port on the right (Dell’s option, nothing to do with the Type-C spec). The HDMI port on the right is a discrete one.

USB 3.1 ports with 5Gb/s and 10Gb/s modes and DisplayPort and USB Power Delivery ports can be identified by icons that can be placed on the ports’ labels. However, the maker is largely responsible for deciding how to employ them. So if you acquire a new computer, you should read the fucking documentation and figure out what the Type-C connectors are used for.

Do All USB C Cables Support DisplayPort?

Although the DisplayPort-over-USB protocol allows for connecting DisplayPort and HDMI displays using an adapter, not all PC manufacturers, have integrated the ports with their systems’ graphics hardware. Some USB-C ports on a plan may support the video-out connection but not by others or by any ports at all.

Can All USB C Cables Transfer Video?

Files, including photos, videos, and music, can be transferred between your mobile device and a USB-C computer at speeds of up to 10 Gbps. You may connect your laptop, phone, or tablet to your HDTV or monitor and play 4K (UltraHD) movies and audio.


That’s all I have on Do All USB-C Cables Support Video? If your laptop supports the “DisplayPort alt-mode,” you can use a dongle to convert the connectors to work with a DisplayPort display via the USB-C port. However, this is laptop-dependent.

Using USB-C, the fundamental issue is that there is no standard for which “alt modes” host devices must support. USB 3 and USB 2 protocol-level data transfer compatibility and power delivery (PD) negotiation for greater wattages than the original USB 2/3 requirements are the only things you can count on.

Thunderbolt and heaven know what else has been defined as an alternate mode protocol for anything from DisplayPort and HDMI to digital headphones. Unfortunately, you’ll have to check the hardware specifications of the host computer to see if any of these alternative modes are supported there.

Frequently Asked Questions

What kind of USB-C video is supported?

Enhanced power supply, native AV support, support for video displays up to 4K, backward compatibility, and a data transfer rate of 10Gbps are some of USB 3.2 Type C Gen 2.

How can I tell whether my USB-C cable is video compatible?

Symbols or logos next to the ports on a Windows laptop indicate what can be done with a particular port. Next to the USB-C port, is there a lightning bolt sign (Thunderbolt 3)? You can then charge your device and send a video signal over this connection. That means you can hook up a monitor to your computer.

Is it possible to transfer a 4K video over USB-C?

When connected to a USB-C or HDMI monitor, Ultra-HD 4K video can be displayed. That’s four times the resolution of HDTV.

Is video supported by USB Type-C 3.1?

DisplayPort-enabled USB 3.1 connections can also be used to carry data, transfer power, and even supply power input over a single cable if the hardware and cable are both compliant.
