USB Connector Types

The connectors on each end of a USB cable serve as a visual cue-a look at some of the more prevalent ones.


This is the standard USB connection, which is found on the end of most USB cables. Only one method to link it is possible.

USB-A ports may be found on almost every desktop and laptop computer. It isn’t only televisions and video games that feature a USB port.


This is a vintage connection that is seldom seen in modern systems. At one end, it is almost square, and it is generally connected to a printer or other equipment. However, the newer standards with the type B USB port below have essentially replaced it in all other applications.


This is a form of connection most suited to smartphones and other portable devices in keeping with the name. There are still some cameras, MP3 players, and other gadgets that use it, despite the widespread adoption of micro-USB.


All sorts of portable gadgets use this small connection. A micro-USB port is found in various electronic devices, including Android smartphones, external batteries, and Bluetooth headphones. On the other hand, a few instruments have adopted the newer USB-C connector.


This is the most current USB specification. One end of the cable has a USB-A connector, while another has another connector. USB-C cable may thus link two devices that both have USB-C ports. It’s also reversible, unlike the different sorts.

It’s taking some time for USB-C to gain traction among device makers. The Samsung Galaxy S9 and Google Pixel employ USB-C and several other recent Android phones. Only USB-C ports are available on Apple’s newest MacBook and MacBook Pro models.

Speed Standards Of The USB

USB 1. x

A year after introducing USB 1.0 in 1996, USB 1.1 ushered in an era of innovation in the USB standard. USB-A and USB-B connections were all that could be used, and today’s standards significantly date that.

A USB 1. x device or cable is scarce to be found today.

USB 2.0

In the year 2000, USB 2.0 was introduced. Version 2 supports a slew of additional ports, including many that weren’t included in version 1.

With USB OTG (On The Go) capability, two USB devices may interact directly with one other. You may, for example, use an adapter to connect an Android phone to a conventional USB keyboard.

USB 3. x

In 2008, USB 3.0 was released, followed by USB 3.1 and USB 3.2. USB 3.0 has a significant advantage over USB 2.0 in transmission rates.

USB Ports For Computer Monitors

Monitors with USB ports are used to expand the connectivity of the PC they are attached to. In the same way, a USB hub or extender is used in this case. Two kinds of USB ports may be found: Type A and Type B.

Ports for connecting accessories such as a mouse or keyboard are available through USB IN type B (square). The PC will be able to communicate with whatever you attach to them.

Contrary to popular belief, these ports are not used to play files directly on display. Only monitors with Smart TV features can do this.

To connect the monitor to the PC, you’ll need a USB port UP type A (rectangular). To connect your computer to your printer, you’ll need a USB cable.

After connecting the monitor to the PC, it will become a USB port HUB, allowing you to connect USB devices to the monitor’s other ports, and it will function as if they were linked to the PC.

USB Ports For Smart TV Monitors and TV Monitors

One of the USB ports (marked 5V and 1A) on Smart TV displays may normally connect external hard drives, while the other two are used to connect memory sticks.

The USB ports on these displays may be used to play multimedia material straight from USB-enabled devices.

There may be a square USB port to connect to the PC, which may be used as a HUB or USB extension (see the computer monitors section).

One USB port is available on TV monitors for the playback of multimedia material (pictures, music files, and video files) following the restrictions in each model’s user manual (codecs, memory device size, file format FAT/NTFS). These ports can only be used to connect storage devices (mice, keyboards).

Frequently Asked Questions

Ensure you connect the USB-C end of the adapter to your Surface’s USB-C port. Plug the adapter into the end of the video cable linked to your external monitor or TV. DisplayPort, HDMI adapter, or VGA are all different types of video connections, so which cable you use depends on the kind of monitor you have.

How do I know if my USB port is damaged?

Check the USB port for damage by connecting several devices to it. Moreover, if none work, the port is most likely faulty. Plug the same USB devices into the same ports on a separate computer. Another sign that your ports are damaged is if they operate.

Does the USB to HDMI cable work for the monitor?

HDTVs and monitors may be connected through HDMI. A new HDMI port may be added to your computer’s USB ports. This will allow any computer to benefit from HDMI and its advantages.

Does all USB-C support display?

Not all USB driver C ports have Thunderbolt 3 capabilities, just as not all USB-C ports have DisplayPort Alt Mode functionality. For a USB C port to allow Thunderbolt 3 connections, the vendor must include Thunderbolt 3 capabilities in the USB C Monitor for windows pc.

Does all USB-C support video?

As a result, not all PC manufacturers have linked the USB-C ports to every system’s graphics hardware, despite the standard supporting the DisplayPort-over-USB protocol. All USB-C ports on a computer may enable a video-out connection or none at all.

An extension of USB-C, known as Alt Mode, may be used to transmit non-USB data. Alternate modes are unique to the USB-C port, enabling technologies such as DisplayPort and Thunderbolt 3 to be transferred over the USB-C connectors.

Can USB-C replace HDMI?

The HDCP 2.2 copy protection standard is not yet compatible with USB-C, even though it supports prior versions of the HDCP copy protection standard. Now, that’s a feature only HDMI can provide! As long as “old” gadgets don’t have to fix USB port C connectors, you’ll still require HDMI cables to support them.


This is all about the USB port on monitor not working for us. Expanding your visual workspace is easy, thanks to the variety of connectors that computer displays provide.

Due to the rising demand for high-resolution displays, there has been a rise in the number of ports that are accessible. A single-screen may be inadequate on rare occasions.

Adding a second monitor allows you to run more applications and multitask more efficiently when a single display is insufficient.

Higher quality, quicker speeds, and more compact computer connections may be achieved by connecting a display over USB.
