• HDMI vs. Mini HDMI vs. Micro HDMI: What's the difference? 2025-07-04

  The beauty of HDMI is how each new iteration maintains compatibility with previous versions. You can get an HDMI connection from an old laptop or Xbox 360 console and display it properly on a brand new 8K TV. ? Contrast this with older analog standards, which often required an intermediary device to convert a SCART, component, S-video, or similar connection to digital-ready HDMI, and without such an interface, it's difficult to display older consoles and computers on modern TVs. The latest HDMI 2.1 standard is fairly new, with the first source devices such as the Xbox Series X, PlayStation 5, and NVIDIA's 30-series graphics cards coming out in 2020. While the standard continues to evolve, HDMI 2.1 is the foreseeable future. ? HDMI 2.1 supports 10K streams at 120Hz and display stream compression, enhanced Audio Return Channel (eARC) for bar speakers and home theater receivers, audio formats such as Dolby Atmos, and gaming features such as native Variable Refresh Rate (VRR) technology. ? Type-A connectors are ubiquitous and cables are readily available. If HDMI is to be replaced, USB-C is probably the leading candidate. HDMI over USB-C is already possible, but HDCP 2.2 support is currently limited to HDMI. The only other technology that might replace HDMI is some sort of wireless standard. While wireless display technology is useful for portable devices (technologies such as AirPlay are already enabled), wireless technology is known to be prone to interference. As a result, it makes little sense for static devices such as game consoles or Blu-ray players to use a wireless connection, even if it reduces cable clutter. ?

  Life, whether it is a computer, TV or projection equipment, are inseparable from the video output interface. Currently on the market, the main video interface HDMI, VGA, DVI, DP these four. With the further development of high-definition equipment, the current market mainstream is the HDMI interface, DP interface is also widely used. So what is the difference between HDMI and DP? Which is more high-definition? Who is more advanced? Why is DP not HDMI popularity? First of all, to know the answer to this question, let's first understand the HDMI interface and DP interface. HDMI interface: High Definition Multimedia Interface (High Definition Multimedia Interface), can be very good at transmitting uncompressed high-definition video and multi-channel audio data, HDMI interface's biggest highlight is that you only need a HDMI cable can be transmitted at the same time the audio and video signals without the need to convert the signals before the transmission can be guaranteed to the highest quality audio and video signal transmission. This ensures the highest quality of audio and video signal transmission. DP Interface: Display Port is a high-definition digital display interface standard that connects computers and monitors, as well as computers and home theaters. With an active or passive adapter, this interface is backward compatible with legacy interfaces such as HDMI and DVI. The leading manufacturers are not the same, and does not matter more high-definition and more advanced a say! HDMI is led by TV manufacturers (mainly some Japanese companies); DP is led by the VESA Association (mainly members of the PC, monitor manufacturers).HDMI requires a license fee, every production of a cable need to pay the fee, DP does not need. In the next issue we'll continue to explore the differences between the two.

• How much do you know about HDMI? 2025-06-18

  The cause is a friend with a 20-meter HDMI cable, and then found that the signal attenuation is serious, just to give you some knowledge about HDMI cables, this article mainly refers to Wikipedia: (https://bk.tw.lvfukeji.com/wiki/HDMIhttps://bk.tw.lvfukeji.com/ baike-DisplayPort), in addition to thank Mr. Xia's technical support. High Definition Multimedia Interface (English: High Definition Multimedia Interface, abbreviation: HDMI) is a fully digitalized image and sound sending interface that can send uncompressed audio and video signals.HDMI can be used in set-top boxes, DVD players, personal computers, videotouring instruments, synthesized amplifiers, digital stereos and televisions, and other devices. HDMI can be used in set-top boxes, DVD players, personal computers, television musical instruments, integrated amplifiers, digital audio and television sets, etc. HDMI can send audio and video signals at the same time, due to the use of audio and video signals with the same cable, greatly simplifying the installation of the system wiring. 1. Different HDMI connectors From left to right are HDMI (A TYPE), mini-HDMI (C TYPE) and Micro HDMI (D TYPE). HDMI (A TYPE): Applied to HDMI version 1.0, there are a total of 19 pin, specifications for the most common HDMI connector specifications for 4.45 mm × 13.9 mm, phase point-to-point in the DVI Single-Link transmission. Before HDMI 1.2a, the maximum TMDS transmission is 165MHz, so the maximum transmission specification can only be 1600×1200 (TMDS 162.0 MHz). mini-HDMI (C TYPE): commonly known as mini-HDMI, applied to HDMI version 1.3, a total of 19pin, can be said to be a scaled-down version of the HDMI A type, the specifications of 2.42 mm × 10.42 mm, but the definition of the foot position has changed. It is mainly used in portable devices, such as DV, digital cameras, portable multimedia players and so on. Due to the size limitation, some graphics cards will

• How to distinguish HDMI cable is superior or inferior? Read these points to understand! 2025-06-14

  With the development of science and technology, more and more products from the expensive price to the point where everyone can get, as HDMI cable, two decades to the present day, the cheapest and even a few wallet mail. But as a very important material HDMI cable, a penny a penny, want to get a better experience, or to follow the agreed reasoning. However, there must be a lot of partners are curious about the difference between a few dollars of wire and the wire sold online for hundreds of dollars. Today we will be from the core, interface and support for the HDMI version of the three points to do an exploration. The better the core, the more stable the signal HDMI cable appearance and other products, it looks flat, but the actual body of the cable has its own universe. Currently we use HDMI cable, the standard is 19-pin interface, that is, the internal 20 cores, 19 +1 (ground), so as to ensure that our signal transmission is guaranteed. While some jerry-built cables, but only 13-core or 15-core, it is easy to appear flickering, snow, black screen, color is not saturated, poor sound quality and other phenomena. For HDMI cable, there are four common wire gauge 22AWG, 24AWG, 26AWG, 28AWG, the larger the number of HDMI cable core the finer, the shorter the transmission distance. So in general the higher the purity of the wire core, the thicker the diameter of the wire can reduce signal loss, shielding thick, dense can reduce interference, thick wire skin, can improve the strength of the wire, improve stability. The material of the wire core is mainly divided into oxygen-free copper, recycled copper, copper-clad steel and copper-clad iron. In the production process, the choice of copper wire is also divided into tinned copper, bare copper wire, copper-clad steel, copper-clad aluminum and other classifications, in order of good and bad.

• How to choose HDMI cable? 2025-06-13

  How to choose HDMI cable? It is recommended to choose according to the actual needs: 1, cable length: according to the use of scenarios, to determine the length of the HDMI cable; 2, core selection: copper core HDMI cable or fiber optic HDMI cable? It is recommended to consider according to the transmission distance; 3, the cable version: HDMI2.0 version, support for 4K @ 60hz resolution and refresh rate; HDMI2.1 version, support for 8K @ 60hz \ 4K @ 60hz resolution and refresh rate; 4, the brand and the price: it is recommended to choose the senior brand, quality control is more secure! Fiber optic HDMI cables use four-core optical fiber as the conductor, using optical signal transmission, and from the signal source to the display device needs to go through two photoelectric conversion. Copper HDMI cable to 4 pairs of copper twisted pair as a conductor, the use of electrical signal transmission, do not need to go through two photoelectric conversion. Due to different transmission principles, there are differences in transmission performance. Ordinary copper HDMI HD cable transmission is stable and reliable, and cost-effective, in the 20-meter range of short-distance scenarios in a very wide range of applications, but encountered long-distance video transmission, even with a signal amplifier can not be more than 30 meters, if forced to extend, it will lead to the video image quality will plummet, and even unavailable. In contrast, fiber optic HDMI cable is finer and lighter, communication capacity, transmission is completely free from external electromagnetic interference, can achieve more than 100 meters of lossless transmission signals, and no signal amplifier, a good solution to the traditional copper-core HDMI cable can not be achieved long-distance transmission. Simply put, copper HDMI cable is suitable for short-distance transmission scenarios, while fiber optic HDMI cable is more adaptable to ultra-high-speed, ultra-long-distance audio-v

• What is USB 3.2? 2025-06-10

  USB 3.2 is a USB (Universal Serial Bus) standard that builds on the previous USB 3.0 and USB 3.1 standards. It was developed to provide faster data transfer speeds and higher overall performance. Increased data transfer speeds: USB 3.2 supports multi-channel data transfers at higher speeds than its predecessor.USB 3.2 Gen 2x2 (the fastest version) has a maximum theoretical data transfer rate of 20 gigabits per second (Gbps). This is achieved by using two 10 Gbps channels for a total transfer rate of 20 Gbps. Backward Compatibility: USB 3.2 maintains backward compatibility with USB 3.1 and USB 3.0 devices. This means you can use USB 3.2 ports and cables with older USB devices, but data transfer speeds will be limited to USB 3.1 / 3.0 speeds. Interface Connector Types: USB 3.2 can use a variety of connector types, including the familiar Type-A, Type-B, and reversible Type-C connectors. The type of connector used depends on the specific implementation and hardware. USB 3.2 Gen 2x2: 2x faster than USB 3.1 Gen 2 (20 Gbps). ? USB 3.2 Gen 2x1: Equivalent to USB 3.1 Gen 2 (10 Gbps). ?

• USB 3.0 Adapter CableUSB 3.0 Adapter Cable Type 2025-06-06

  There are three main types of USB 3.0 interfaces: Standard Type A, Standard Type B and Mini Type B. Among them, the standard A-type interface is compatible with USB 2.0 devices, but the connection will reduce the speed. And the standard B-type interface is not backward compatible and is mainly used to connect peripherals. For example, adapter cable types such as AM TO AM, AM TO BM, AM TO AF, AF TO AF, AF TO BM, AM TO BF, AM TO Micro USB3.0, etc. belong to this category. AM TO AM adapter cables are used to connect the two ends of a standard type A connector to facilitate the transfer of data between devices.AM TO BM adapter cables connect a standard type A connector to a standard type B connector for scenarios that require the use of a peripheral.Adapter cable types such as AM TO AF, AF TO AF, AF TO BM, AM TO BF, and AM TO Micro USB3.0 are connect the standard A-type interface to other types of interfaces for data transfer between different devices. These adapter cables are very common in daily life, such as the connection of computers, cell phones, cameras and other devices. Standard B-type interface is mainly used to connect peripherals, such as keyboard, mouse, printer, hard disk, etc. AM TO BM adapter cable connects standard A-type interface with standard B-type interface, so that users can use standard A-type interface devices to connect with peripherals. While adapter cables such as AF TO BM, AM TO BF and AM TO Micro USB3.0 connect the standard type A interface with other types of interfaces to realize data transfer between different devices. These adapter cable types not only facilitate users to transfer data between different devices, but also greatly improve the compatibility and flexibility of the devices. In conclusion, USB 3.0 adapter cables are the bridge between different devices, whether it is the connection between the standard A-type interface and the standard B-type interface, the mini B-type interface or other

• What is USB 3.0, 3.1 and 3.2 and what's the difference under the confusing nomenclature? 2025-06-03

  In the past, it was easy to choose the fastest USB, you just need to recognize USB 3.0 instead of USB 2.0. However, nowadays, you can see a lot of products in the market labeled USB 3.2 Gen1, Gen2, Gen3 or Gen2×2, which makes the matter of shopping for USB confusing. Now, we will guide you through the differences between USB 3.0, 3.1 and 3.2 (USB 3.2 Gen1, Gen2 and Gen2×2). At one time, there were only two major versions of USB, 2.0 and 3.0, and all you needed to know was that 3.0 was just faster than 2.0. You can buy a USB 2.0 flash drive and plug it into a computer that has a USB 3.0 port and it will still work fine, but only at USB 2.0 speeds, and when you plug a USB 3.0 flash drive into a USB 2.0 port you will also only enjoy USB 2.0 speeds. If you want to reach peak speeds, you need to use a USB 3.0 flash drive with a USB 3.0 port, it's as simple as that, but with USB 3.1, everything changes. ? USB 3.1 Naming Confusion ? The U.S. USB standardization organization (USB-IF) is responsible for maintaining and updating USB specifications and norms, and providing naming schemes for USB cables and devices. When they introduced USB 3.1, they didn't simply make the name distinguishable from USB 3.0, but instead named the new standard “USB 3.1 Gen2” while renaming the old USB 3.0 as “USB 3.1 Gen1 “. ? To complicate matters, even the transfer speeds themselves have been renamed. USB 3.1 Gen1 (formerly USB 3.0) is capable of 5Gbps transfer speeds and is called “Super Speed”; USB 3.1 Gen2 (the new USB 3.1) has a transfer speed of 10Gbps and is called “Super Speed+”, which technically achieves this by using 128b/132b encoding in full-duplex transfer mode. Full-duplex transmission mode means that data can be transmitted and received at the same time, which is why it's faster. ? ? The difference between the two is a bit confusing, but for th

• USB3.1 High Speed Interface Design Guide 2025-05-30

  usb 3.1 cable USB Type-C, also known as USB-C, is a Universal Serial Bus (USB) hardware interface form, the appearance of the most important feature is that its upper and lower ends are completely consistent with the Micro-USB compared to this means that the user does not have to distinguish between the USB positive and negative, both directions can be inserted.01USB Classification Talking about the form, just said the mini-USB and micro-USB is also considered such, but these two relative to the standard USB. And this standard USB, in fact, its name is USB Type-A. Type-A USB 3.0 and 2.0 have the same shape, and the devices are compatible with each other, while Type-B is different, the 2.0 version of Type-B wiring can be plugged into the 3.0 version of the interface, but not the other way around.02Type-C has functions and features USB 3.1 is divided into two types of Gen 1/Gen 2. USB 3.1Gen1 is a renaming of USB 3.0, which means that there is no change at all. All the end of the market mentioned Gen 1/Gen 2 distinction, generally refers to USB 3.1 Gen2. USB 3.1 Gen 2 has a bandwidth of 10Gbps, which is double that of USB 3.0. The bandwidth for video and audio transmission (USB AV) has been increased to match that of HDMI 1.4. Power output up to 100W Coding standard change, upgraded from 8b/10b to 128b/132b greatly reduces the coding loss rate. 03Type-C exclusive features 1F supports forward and reverse plugging Although successive generations of USB have anti-plugging reverse design, but this does not prevent the tragedy of “vigorously out of the miracle” after the tragedy .... So this time from the source to solve the problem, forward and reverse plug can be used, no longer encountered when plugging the USB to try once before plugging in the embarrassment.

• There is a way to choose HDMI cable? It turns out that you have always bought the wrong one before! 2025-05-28

  There are not only many brands of hdmi cables on the market, the price range also varies, from single digits, to ten dollars, and even tens of dollars of HDMI cables. Considering that HDMI cables are durable consumables, I decided to do my homework seriously and choose an HDMI cable properly. When choosing an HDMI cable, there are only two places to focus on, version and material. HDMI2.0 version of the cable, the transmission bandwidth of 18Gbps, the highest support to 4K/60 frames, 8k hdmi cable usually watch a high-definition TV at home, or connect to a general monitor, obviously more than enough. ? HDMI2.1 version of the cable, the transmission bandwidth of up to 48Gbps, the highest support to 8K/60 frames, although the current price of 8K TV is more expensive, 4K TV is still the mainstream, but HDMI2.1 is also backward compatible with 4K/120 frames as well as 2K/240Hz. for host users, such as the PS5 as well as the XBox Series X are supported 4K/120 frame output. 120 fps screen output, want to experience HD + high brush screen, obviously on the 2.1 specification cable. ? PC game users, not to mention that some high-end gaming monitor support to 4K/144Hz, and HDMI2.0 only 18Gbps bandwidth, obviously can not meet the demand for gaming monitors, and therefore also need to be on the 2.1 specifications of the HDMI cable. The material of HDMI cables and connectors is generally referred to as the material of HDMI cables and connectors.HDMI cables, as durable devices, naturally need to ensure that they are durable enough. Whether the cable will oxidize after a long time of use and whether the connector will rust is an important criterion to measure the durability. ? Then there is the interface rust design, generally speaking, high-quality HDMI cables, the interface will be gold-plated or nickel-plated design, to enhance the antioxidant, rust-resistant ability, the

HDMI cable on the market in addition to 1.1, 1.3, 1.4, 2.0 a few versions, there are such as HDMI-a, HDMI-b, HDMI-c these interfaces, more versions, compatibility will need to pay attention to, generally backward compatible, that is to say, the new version of the HDMI2.0 can be compatible with the 1.4, but the 1.4 is not fully compatible with the HDMI2.0, that is, it is capable of Use, the function is not complete, the best in the purchase of HDMI cable directly with the latest HDMI2.0 version, the best in the purchase of HDMI cable. ? 2, appearance. ? Appearance can not change the practicality, but can illustrate the quality of the product. At a glance, if the HDMI cable appearance of some glue, burrs and so on is not to say that can not be used, poor quality and so on, but is sure to show that it is inferior goods. ? As for packaging, this is not important, we all know. 3, connectors. ? For HDMI cable, including VGA and so on, when the connector contact is poor, of course, the signal transmission will be worse, and even can not be used. The gold-plated connector, in use for a long time still maintain good contact and conduction. ? The high-quality connector, basically will be plated with 24k gold, but the thickness of the gold plating will react to the grade of HDMI cable. ? In addition to gold-plated, there is a connector material, generally iron, aluminum, copper three, iron will rust, aluminum will oxidize and its own conductivity is not good, copper is the best. ? Of course, HDMI connector gold-plated or not, how the material, the impact on the picture quality is not great. ?

• What's new in USB4 cable? 2025-05-12

  ? USB 4 (formally known as “USB4” without the spaces) is an important upgrade not only because of its new features, but also because it removes the confusion associated with USB 3.x naming and provides a predictable and understandable experience for the user. USB4 protocol requires a USB-C <-> USB-C cable. ? Data transfer speeds up to 40 Gbps: USB4 devices must support 20 Gbps (2.4 GB/s). USB4 devices must support 20 Gbps (2.4 GB/s). If the device uses a shorter 40 meter Gen 4.8 cable, it can support an additional 3 Gbps (0.8 GB/s). ? Multiple data and display protocols: The USB4 supports USB 3.2, PCIe, and DisplayPort 1.4a through a technology known as protocol tunneling; alternate modes also support DisplayPort and Thunderbolt 3. ? Backward Compatibility with USB 3.2, USB 2.0, and Thunderbolt 3: The USB4 supports compatibility with previous versions of the USB specification and, thanks to its Thunderbolt 3 base, also supports TB3 alternate mode. ? Video and data bandwidth optimization: USB 3.2 allocates a fixed bandwidth for data or video signals, and provides 100% bandwidth for video in DP Alt mode. the USB4 dynamically allocates video and data bandwidth based on actual needs. ? 100W Charging: All USB4 devices support USB power. When a device is plugged into a USB4 port, USB PD is “contracted” to supply power, safely delivering up to 100W (5A/20V). ? What is protocol tunneling? When devices communicate with each other, they use a specific protocol to communicate. If both devices can communicate and understand the same protocol, a connection will be established. Essentially, protocol tunneling uses one protocol to create a “channel” and uses it to send data in another protocol. usb4 protocol tunneling creates a USB-C tunnel through which DisplayPort or PCIe data can be sent. usb4 pro

• What is USB 3.2 and how does it different from USB-C and USB 3.1? 2025-04-25

  USB-C, USB 3.0, USB 3.1, USB 3.2 Confused? These numbers represent not only the form factor, but also the different standards and transfer speeds. They all look the same on the outside, but in reality there is a big difference. So what's the difference between USB 3.1 and other formats like USB 3.2 or USB-C? Let's talk about it today. USB 3.1 refers to the transmission format, which is all about data and speed. USB 3.1 is the codename for USB Transmission Subwoofer, which mainly refers to the data transfer speed of the USB connector, rather than describing the shape or size like USB-C. USB 3.1 was officially launched in July 2013, replacing USB 3.0 as the new high-speed USB standard. ? However, USB 3.1 is not the strongest, as USB 3.2 has now replaced USB 3.0 and USB 3.1. However, USB 3.2 is just a re-branding of USB 3.0 and USB 3.1, so it's getting more and more confusing. The official naming conventions and their respective speeds are as follows: USB 3.2 Gen 1 = USB 3.0. Maximum speed: 5Gbps. alternatively known as SuperSpeed USB. USB 3.2 Gen 2 = USB 3.1, maximum speed: 10Gbps, also known as: SuperSpeed USB 10Gbps. USB 3.2 Gen 2×2 = USB 3.2. Maximum speed: 20Gbps. also known as: SuperSpeed USB 20Gbps. How to use USB 3.2 Gen 2 One of the advantages of USB 3.2 Gen 2 is that it supports Power Delivery 2.0. It provides up to 100W of power for charging notebooks, and many notebooks that use USB-C support this standard. USB-C does not mean USB 3.1 USB-C is associated with USB 3.2 Gen 2 and Gen 2×2, but that doesn't mean your USB-C supports USB 3.2. USB-C is just a representation of the form factor, with the letter types, such as A, B, and C, indicating the USB form factor, and the number types (3.2, etc.) indicating the data transfer capability. Most computers nowadays use USB-A or USB-C, and USB-C is more common due to its smaller

• USB 3.2 Comes of Age: Speed Boosts and the Future of New Interfaces 2025-04-24

• USB 3.2 Gen 2x2 standard 2025-04-22

  Technology Realization and Market Impact Realization and Market Products The core breakthrough of USB 3.2 technology is the support of multi-lane operation. This technology cleverly utilizes the unused wires in the USB data cable, combining two lines each with a 5GMbps or 10GMbps rate in a serial combination, thus enabling USB 3.2 to reach a theoretical transfer speed of up to 20GMbps. ? Multi-Line Operation Technology Despite the significant increase in speed, the USB 3.2 standard has not made significant changes in other areas. In addition, USB 3.2 will continue to use the USB-C interface, and in most cases, users will not need to replace the new cable to enjoy the high-speed transmission experience of the USB 3.2 standard on their cell phones or laptops. ? User Experience and Device Selection Recommendations User Impact of the New Technology The minor upgrade to USB 3.2 means that the interfaces of our everyday electronic devices can support the new technology without major changes. So how do we keep our USB devices up to date? The fact is that older USB standards tend not to be obsolete for a long time, and the newer standards are often compatible with the older ones, only with reduced performance. This means that even if you're currently using a microUSB-connected phone, there's no need to rush to replace it with a USB-C phone just because the new USB-C connector is becoming more popular. Meanwhile, various accessories will continue to support microUSB for some time. ? Device Selection Advice To ensure that the USB devices you purchase are not rapidly becoming obsolete and can take full advantage of the new technology in the coming period, it is recommended that you choose a device that has both USB 3.1 and USB-C standards. While a new purchase will not directly increase the speed of your old device, it lays the groundwork

• The difference between usb 3.2 and 3.0？ 2025-04-18

  The difference between USB 3.2 and USB 3.0 is primarily one of speed and naming convention. Understanding this difference is a bit of a workaround, as the USB Extension Organization (USB-IF) has made a number of changes to the nomenclature. Here are the key points of difference: ? Base Speed and Evolution: ? USB 3.0: Originally released with a defined speed of 5 Gbps (gigabits per second), also known as SuperSpeed USB. ? USB 3.1: The USB 3.1 standard was later introduced, and it consists of two versions: ? USB 3.1 Gen 1: The speed is still 5 Gbps, which is actually the new name for USB 3.0. ? USB 3.1 Gen 2: The speed was increased to 10 Gbps and was called SuperSpeed USB 10 Gbps. ? USB 3.2: Later, the USB-IF released the USB 3.2 standard and changed the naming convention again, bringing the previous USB 3.0 and USB 3.1 into the USB 3.2 category and adding a faster speed class: ? USB 3.2 Gen 1: 5 Gbps. This is the original USB 3.0 and USB 3.1 Gen 1. ? USB 3.2 Gen 2: 10 Gbps. This is the original USB 3.1 Gen 2. ? USB 3.2 Gen 2x2: 20 Gbps. This is the highest speed added to USB 3.2 and utilizes the dual-channel transfer capability of the USB-C interface (two 10 Gbps channels). ? Naming Confusion and Current Status: ? Due to the ever-changing nomenclature, you now see “USB 3.2” which may refer to speeds of 5 Gbps, 10 Gbps, or 20 Gbps. ? The old designation of “USB 3.0” should technically now be called “USB 3.2 Gen 1”. ? So the core difference is that USB 3.2 is a collection of newer standards that incorporate USB 3.0 speeds (5 Gbps) and expand upwards to faster speeds (10 Gbps and 20 Gbps). ?
