Ⅹ Frequently Asked Questions About USB C to HDMI

 

Ⅰ Introduction

Many laptops and other electronic devices employ USB C connectors, and the trend is for them to have solely USB C as their only type of interface connector.

 

This looks to be a problem when items such as TVs, computer monitors, projectors, and the like only support HDMI, necessitating the need of a means of interface between the two standards.

 

Using a simple cable with a USB-C connector on one end and an HDMI connector on the other is one of the simplest solutions. There are also adapters with a USB-C port on one end and an HDMI cable socket on the other.

 

What is USB-C?

 

USB Type-C, also known as USB-C, is quickly becoming the standard connector for transferring data and power to and from a wide range of computing devices. Its symmetrical design allows it to be placed either way — up or down — removing many of the difficulties associated with previous USB ports and placing it on par with  Apple's reversible Lightning plug.

 

This alone makes it a winner in my book. However, USB-C is still evolving toward faster data transfers and the potential to deliver more power to devices. It's also tightly tied to a number of strong new technologies, such as Thunderbolt and USB Power Delivery, which have the potential to revolutionize how we think about our gear and how we operate in the office, on the road, and at home.

 

But there is a downside. USB-C is merely a connector type; it's based on the Universal Serial Bus specification, which is where things become complicated. The four main USB protocols in use today are, to say the least, perplexing, resulting in an alphabet soup of standards that may confuse even the most technically savvy among us. The specifications are as follows:

 

  • The USB 3.2 Gen 1 protocol is the most widely used USB specification today. It supports a maximum speed of 5Gbps over a single data lane and can use either an old-school Type-A rectangular connection or the oblong USB-C connector.

 

  • The next step increase in speed is divided into two options: utilization of double speed data lanes that adhere to the former speed limit (USB 3.2 Gen 1 x2) or a single lane that runs at twice the speed (USB 3.2 Gen 2x1). In either case, the peak throughput is 10Gbps.

 

  • The USB 3.2 Gen 2x2 standard, which uses two channels of double-speed data flow to reach 20Gbps, is the most current iteration.

 

To add to the confusion, the USB 3.2 single-lane protocols are essentially rebranded USB 3.1 protocols, which may still be found on some devices. USB 3.1 Gen 1 is equivalent to USB 3.2 Gen 1, while USB 3.1 Gen 2 is equivalent to USB 3.2 Gen 2x1.

 

Ⅲ What is HDMI?

 

HDMI is a proprietary audio/video interface that transmits uncompressed video data and compressed or uncompressed digital audio data from an HDMI-compliant source device, such as a display controller, to a compatible computer monitor, video projector, digital television, or digital audio device. HDMI is a digital video standard that replaces analog video standards.

 

HDMI adheres to the EIA/CEA-861 standards, which describe video formats and waveforms, the carriage of compressed and uncompressed LPCM audio, auxiliary data, and VESA EDID implementations. HDMI CEA-861 signals are electrically compatible with the Digital Visual Interface CEA-861 signals (DVI). There is no need for signal conversion, and there is no loss of video quality when using a DVI-to-HDMI converter. Consumer Electronics Control (CEC) allows HDMI devices to control each other and allows the user to operate many devices with a single portable remote control device.

 

Since the technology's first debut, other versions of HDMI have been developed and deployed, but all use the same cable and connector. Newer versions contain optional advanced capabilities such as 3D, Ethernet data connection, and CEC extensions, in addition to increased audio and video capacity, performance, resolution, and color schemes.

 

Consumer HDMI products were first manufactured in late 2003. In Europe, either DVI-HDCP or HDMI is included in the HD ready in-store labeling specification for TV sets for HDTV, which was developed in 2005 by EICTA and SES Astra. HDMI first appeared in consumer HDTVs in 2004, followed by camcorders and digital still cameras in 2006.

 

USB-C to HDMI Information

 

To connect a USB C port to an HDMI port, a USB-C to HDMI cable that acts as an adaptor is required.

 

These USB-C to HDMI converter cables are widely accessible and provide a perfect way for laptops and other PCs, among other things, to interface with HDMI-based items such as displays, screens, televisions, and so on.

 

The HDMI Forum, which licenses HDMI technology, decided to build a USB-C to HDMI interface since the USB-C interface is becoming increasingly popular and there is a rising demand to interface to A/V goods such as smartphones, televisions, laptops, and display monitors.

 

Resolutions up to 4K, Audio Return Channel, 3D, HDMI Ethernet Channel, and Consumer Electronic Control are all supported by USB-C to HDMI cables and adapters.

 

How do USB-C to HDMI Adapters & Cables Work

Because the transmission formats and amount of lines available in USB-C and HDMI are considerably different, the HDMI port must be able to modify its functioning.

 

The HDMI port can use a feature known as HDMI Alternate Mode, or HDMI AM. The cable can interface straight from USB-C to HDMI in this mode.

 

This functionality was added in September 2016, and it enables features up to and including those found in HDMI 1.4b, such as video resolutions up to Ultra HD at 30Hz and Consumer Electronic Control, CEC.

 

Because the connectors for the USB-C connector and the HDMI connector differ, the HDMI port reconfigures the four SuperSpeed differential pairs of the USB-C interface to carry the three HDMI TMDS channels and the clock signal in Alternate Mode.

 

The HDMI Ethernet and Audio Return Channel, as well as the Hot Plug Detect capabilities (HEAC+/Utility pin and HEAC/HPD pin), are carried by the two Sideband Use pins SBU1 and SBU2.

 

The USB-C port then has inadequate pins for the DDC clock, SCL, DDC data, SDA, and CEC. To accommodate these, the three signals are bridged between the HDMI source and sink using the USB Power Delivery 2.0, USB-PD protocol and sent over the USB-C Configuration Channel, CC line.

 

There are a few compromises, as one might expect given that the HDMI Alternate Mode crams the HDMI capability into a smaller number of lines. The first is that the Alternate Mode is based on the older HDMI 1.4specification rather than the more recent HDMI 2.0b. This means that HDMI Alt Mode for USB-C connections will be able to output up to 4K quality, 3D video, and support HDMI-CEC, but it will not support HDR video or other features introduced in HDMI 2.0b.

 

How to use USB-C to HDMI Cable?

6.1 Preparation

It is really simple to use a USB-C to HDMI connection. You only need to take a few steps.

 

6.2 Connect the USB-C plug into your USB-C device

Connect the USB-C plug to your tablet, laptop, or smartphone.

 

Check that your host device supports video output, which means the USB-C port must support DP alt Mode! (DP Alt mode: Alternate Mode is a USB Type-C capability that allows video signal transmission.)

 

6.3 Connect the HDMI end to the display

Connect the HDMI plug to the monitor or screen where you wish the video to be displayed.

 

6.4 Done

And you're finished. Take use of your content on numerous displays. There will be no need for any additional software.

 

HDMI Alt Mode for USB Type-C Connector page

The HDMI® Alt Mode for USB Type-C TM connector enables HDMI-enabled source devices to connect directly to HDMI-enabled displays via a USB Type-C® connector, delivering HDMI signals and functionality over a single cable without the need for protocol and connector adapters or dongles.

 

This brings together two of the most popular connecting solutions: the tiny form factor, reversible, and multi-purpose USB Type-C connector used by smartphones, tablets, and PC products, and the HDMI connector, which is the dominant display interface with billions of displays installed. Over 355 million HDMI-enabled display devices, including projectors, monitors, VR headsets, and 100% of flat panel TVs, are projected to ship in 2019.

 

HDMI Alt Mode will support the full range of HDMI 1.4b features such as:

  • Resolutions up to 4K
  • Surround sound
  • Audio Return Channel (ARC)
  • 3D (4K and HD)
  • HDMI Ethernet Channel (HEC)
  • Consumer Electronic Control (CEC)
  • Deep Color, x.v.Color, and content types
  • High Bandwidth Digital Content Protection (HDCP 1.4 and HDCP 2.2)

 

It is up to manufacturers to decide which HDMI features to support on their USB Type-C products.

 

Why You Should Connect Your USB-C Device to HDMI

With so many options for connecting your phone, tablet, or PC to your TV remotely, why would you invest in a USB-C to HDMI link?

 

Whether you need to mirror portable gaming to your TV or show family and friends your most recent event photos, a USB-C to HDMI connection can basically minimize any lag you might expect from a remote arrangement.

 

Not just that, if your Wi-Fi isn't working or your remote signal is weak, a link implies you can still connect to an HDMI show.

 

Although most brilliant TVs provide a selection of implicit streaming programs, for example, Netflix and Amazon Prime Video, your cell phone can show the same applications through HDMI if your TV does not.

 

Ⅸ Things to Consider When Buying USB-C to HDMI Cable / Adapter

Because the USB-C to HDMI functionality is so convenient, there are numerous vendors on the market producing similar products. This indicates that there is a good selection and that the costs are extremely reasonable.

 

9.1 Cable vs adapter

There is a wide range of cables and adapters available. Typically, the cable has a USB-C connector on one end and an HDMI socket on the other to connect to HDMI-enabled equipment. The adaptor typically has a USB-C port and a floating HDMI plug. This is then linked to an HDMI wire.

 

These HDMI adapters may be more convenient to use if the HDMI to HDMI cable can be left in place while the adapter is connected to it. The USB-C to HDMI adapters essentially consist of a tiny cable with a female floating socket. Because of their size and weight, they can be relatively easy to transport if an HDMI to HDMI cable is available.

 

USB-C to HDMI cables contain plugs on both ends and will connect the two end points without the use of an additional cable. They are, however, more thick and heavier.

 

9.2 Adapters vs cables

There are numerous USB-C to HDMI conversion options available. You can purchase cables with a USB-C connector on one end to connect to your computer and an HDMI connector on the other end to connect straight to the monitor.

 

Another popular solution is to have a USB-C to HDMI adaptor. For this type of transition, a USB-C cable is plugged into the computer, and then an HDMI to HDMI cable is plugged into the adaptor. These adapters might take the form of a small adaptor "box" or a short cable. These can be pretty useful, but they still necessitate the usage of an HDMI connection. Check what you want, how much it will cost, and whether you already have an HDMI to HDMI cable or whether you would need to get one.

 

9.3 Reliability

It is never easy to assess the dependability of anything. However, as in many other cases, you get what you pay for. Having said that, most adapters and cables will function well and give enough service. Obviously, if the USB-C to HDMI cable or converter is frequently used, it is more likely to fail. Lots of connector insertions and cable flexing, especially at vulnerable locations, will shorten the cable's life.

 

The cable's durability will be an important factor in its dependability. The cable quality may be significant in situations where it will be subjected to a lot of wear. Nylon encased cable is becoming more common, and it is reasonably simple to use for manufacturers. Nylon is both cheap and good in protecting wires in a variety of ways. Many folks who want to use these USB-C to HDMI cables on the go may find this to be an option.

 

Another thing to keep an eye out for is the connectors' construction. Aluminium connectors can be more durable than basic plastic connectors, which can shatter more quickly.

 

Consider the overall robustness of the cable assembly, which can be difficult to determine in many cases, especially online.

 

9.4 Cable length

The length is especially crucial if a cable with USB-C on one end and the matching HDMI to connect directly with the monitor, display, screen, etc. is used. Cables are typically one metre, two metres, or the equivalent in feet, so ensure that the cable is the suitable length for the job.

 

It is frequently helpful to run some string between the two items to be connected and then measure the length of this string. Allow for a little more time because distances are frequently longer than you expect. However, there is a fine line between allowing for a little more and having too much that must be neatly coiled away somewhere.

 

9.5 HDMI Connector Style

Almost all USB-C to HDMI cables and adapters use a standard type A HDMI connector. However, certain USB-C to HDMI adapters are available with different connector sizes, including regular HDMI, mini-HDMI, and micro-HDMI. This appears to be the best approach for the time being, though there are certain to be some USB-C yo small or micro-HDMI cables somewhere.

 

9.6 Supported Video Resolution

Resolution is an important aspect of any digital information, whether it's a movie, a video clip, or even an image. The resolution is essentially a scale that indicates how much space the digital information takes up on the display panel. As you can expect, the panel's video resolution capabilities must be equal or higher in order to handle the video content.

 

However, this is no longer a major issue because even low-cost monitors and TVs can support 4K resolution or at least a QHD 1440p resolution screen. Even if you use such high-end display devices, you won't obtain the same results if your adapter limits the resolution. We've listed the video quality supported by each of our adapters so you don't have to worry about its compatibility with your setup.

 

9.7 Supported Video Refresh Rate

Another critical component is the refresh rate of the video broadcast. When you play a video game on your display, it is rendered at a specific FPS, or frames per second. These frames are displayed on your screen based on their refresh rate. If your display has a refresh rate of 60 Hz, you will only see 60 FPS even if you are playing the game at a higher FPS.

 

Furthermore, if you include extra components in the equation, such as a USB C to HDMI adapter, you must ensure that the adapter is capable of transferring material at such a high refresh rate. If you do not, you will notice a considerable decrease in video transmission and the video stream will appear more slower and stuttery than on your original display. If you're looking for a USB C to HDMI adapter for gaming, ensure sure it has a refresh rate of at least 60 Hz. However, 30 Hz is plenty for watching movies and TV programmes.

 

9.8 Available Ports

The USB C to HDMI adapter's available ports are also crucial to its functionality. The input for these adapters will always be a USB C connection. However, depending on the sort of adapter you purchase, there may be a single or several outputs. You can only use your adapter for display connections if it has a single HDMI port or cable connection.

 

However, because many laptops offer USB C as a universal connector for numerous functions, you may want a USB C to HDMI converter with multiple outputs. There are a few premium choices on the market that provide display connection compatibility as well as additional data transfer ports. There are also a few choices for multi-monitor configurations.

 

9.9 Compatibility

Make sure your USB-C to HDMI cable is compatible with your device before purchasing it.

 

You should also keep in mind that the USB-C port on your device supports DP Alt Mode.

 

DisplayPort Alternate Mode is a useful expansion of the USB-C connector that allows it to connect to another monitor directly.

 

9.10 HDMI Version

When HDMI Alternate Mode was first released, it only supported functionality up to Version 1.4b. As a result, when using a USB-C to HDMI connection or adapter, this should be considered.

 

Ⅹ Frequently Asked Questions About USB C to HDMI

1. How many Volt is a USB port?

A standard USB 1.0 or 2.0 socket contains four pins, and a USB cable contains four wires. The inside pins convey data (D+ and D-), while the outside pins supply power (5 volts). USB 3.0 ports add an extra row of five pins, resulting in USB 3.0-compatible connections with nine wires.

 

2. Is a USB port AC or DC power?

For charging solely, standard USB devices have a 5 V dc voltage and a current of up to. 5 A or 500 mA. This is what allows them to coexist with your computer's USB ports. Most USB wall adapters will be 5 V adapters with current ratings far in excess of.

 

3. How do I connect a USB to my computer?

Insert the flash drive into your computer's USB port. A USB port should be located on the front, rear, or side of your computer (the location may vary depending on whether you have a desktop or a laptop). A dialog box may display depending on how your machine is configured. If so, choose Open folder to view files.

 

4. Where is USB port on computer?

Most USB ports on desktop computers are located on the rear of the computer casing. In general, you should connect your mouse and keyboard to these ports while leaving the front USB ports free for digital cameras and other devices.

 

5. How do I connect a USB to my phone?

(1)Connect a flash drive (or SD reader with card) to the adapter's full-size USB female end.

 

(2)Connect the USB-C end of the cable to your phone.

 

(3)Swipe down from the top of the screen to see the notification shade.

 

(4)Select USB Drive.

 

(5)To view the files on your phone, tap Internal Storage.

 

6. How to use a USB C to HDMI adapter?

It is simple to use a USB C to HDMI adapter. In fact, it is as simple as inserting the connectors into the appropriate port. Simply connect the adapter to your laptop or any other USB C source, and then connect the adapter to an HDMI TV or monitor using an HDMI cable. Some connectors also have an HDMI output cable, so you won't need an HDMI cable at all. Most importantly, no driver is required to use these adapters.

 

7. Is there quality loss between USB C and HDMI?

When you use an adaptor, you risk losing quality. However, when it comes to USB C to HDMI adapters, the quality is nearly non-existent. The high data transmission rate offered by both USB Type C and HDMI is the primary reason for this. If you choose a premium option, you can even obtain up to 4K resolution output at a refresh rate of 60 Hz, if not higher. As a result, these adapters are perfect for gaming-related applications.

 

8. Is using an adapter better than a direct connection?

As previously stated, there is almost little quality loss in these adapters. As a result, instead of a direct connection, you can use these adapters. However, if your laptop has an HDMI or DisplayPort port, we prefer using a direct connection because it eliminates the need for an additional device between the source and the monitor. Direct connections are also significantly more reliable than adapters because there are fewer chances of loose connections.

 

9. What are the 5 wires in a USB cable?

Red, black, white, and green are the most common hues found on the interior of USB cables. Each of these colors shows whether the wire is for charging or data transfer. Although the traditional wire colors in a USB cable are red, black, white, and green, don't be concerned if your cable does not have these colors.

 

10. Does a USB cable draw power?

When plugged in, USB cables and chargers use very little energy and are safe even when the car is turned off. However, this is dependent on whether a gadget is charging, whether electricity continues to run even when the car is turned off, and how long the car will sit before being restarted.
