Что делают входные / выходные USB-порты на мониторе?
Я сталкивался с несколькими настройками монитора, и они включают в себя много разных портов вместе с некоторыми портами USB.
Монитор: DELL P2214H, DELL P2414H
В описании монитора упоминается, что есть и порты «вверх» и «вниз» USB. В чем разница между ними и каковы виды использования каждого типа? Можно ли подключить динамик напрямую к монитору?
Зачем голосовать? что я должен обновить в этом.
На таком мониторе с портами USB в самом мониторе есть концентратор USB. USB-концентратор должен сначала иметь вход от компьютера.

Квадратное соединение TypeB является входом для концентратора, кабель, аналогичный кабелю принтера, с разъемом типа A на одной стороне, и разъем типа B на другой стороне, который будет использоваться для подключения USB-порта компьютера к хаб. Тогда концентратор будет иметь несколько портов.

Как только вы запустите ввод с компьютера, «HUB» предоставит порты USB. Он будет питаться от подключения к компьютеру. Любое подключаемое USB-устройство будет работать в нем, пока оно остается в пределах характеристик электропитания.
Это то, что я ищу. Мое основное недоразумение заключается в том, что, если у него есть USB, он воспроизводит фильмы напрямую, и если да, то как голос будет выводиться из монитора, как я указал, у монитора нет функции звука.
Нет, это не телевизоры, которые могут иметь встроенный медиа-чип для декодирования и воспроизведения картинок и видео с USB-накопителя. в компьютерных мониторах пока они просто концентраторы, и это все.
хороший ответ! Благодарю. Принятые ответы с «нулевыми» ответами всегда меня смущают. Как люди принимают чей-то ответ, а не высказывают его?
@ Psycogeek В этом случае, если я хочу подключить этот монитор к компьютеру через USB, который мне следует использовать?
Если вы хотите подключить монитор для просмотра видеодисплея на компьютере, вы должны подключить его через DVI, HDMI, DP или VGA (в крайнем случае). USB не является устройством вывода видео, хотя вы можете использовать USB-видео ключ чтобы получить доступ к DVI или HDMI я не очень рекомендую, если порт данных не предназначен для видео, как удар молнии или что-то. Для создания цифрового видео в несжатом виде с компьютерных видеокарт хорошо подходят связывающие устройства PCI и встроенное видео, USB имеет тенденцию использовать много процессора и шины для выполнения задач, которые не были предназначены для этого.
Монитор с USB upstream, downstream портом и своим использованием
я наткнулся на несколько конфигурации монитора, и она включает в себя много портов вместе с некоторыми USB-порт.
монитор :
КОМПАНИЯ DELL P2214H
DELL P2414H
в USB-порт, учтите, что входной порт и выходной порт.
Что это за другой тип порта ?
Что польза каждого типа порта ?
Я может подключить динамик напрямую к монитору?

на монитор с портами USB, есть USB-концентратор в сам монитор. USB-концентратор должен иметь вход от компьютера в первую очередь.

TypeB квадратное соединение-это вход для концентратора, кабель, аналогичный кабелю принтера с разъемом типа A с одной стороны, а разъем типа B с другой стороны будет использоваться для подключения USB-порта компьютера к концентратору. Ступица тогда будет иметь несколько портов.

после ввода выполняется на компьютере, «концентратор» будет предоставлять порты USB. Он будет питаться от компьютера. Любое USB-устройство подключения будет работать в нем, пока он остается в пределах спецификации питания.

What is USB upstream/downstream port on monitor ?


USB is an abbreviation for Universal Serial Bus. USB is an industry standard for short-distance communication, such as between a computer and a keyboard, a computer and a mouse, a monitor and a laptop, a printer and a computer, and so on. USB devices are now widespread due to the ease with which they can be configured and connected.
The USB system has two types of ports: downstream and upstream . In this article, I will explain the Downstream and Upstream ports, as well as their applications in the monitor.
Before we get into those ports, there’s one thing you should know. HDMI and RJ45 ports only send data to their respective devices, whereas USB ports can carry both power and data. Due to this USB gadgets do not need an extra cable for power.
Upstream Port
. These are linked using the cable below, which has both Type A and Type B ports. </p>
<p>As power and data are received by the monitor from Desktop PC / laptop so, the content of the laptop and desktop will be visible on the monitor. Therefore, the Upstream port is present in the monitor. This doesn’t mean that the monitor does not require power. Monitors need extra AC mains cable to plug into an outlet. But if you consider thunderbolt and USB Type C port-based monitors they may not need extra power cables because they can drive enough power to an LCD monitor.</p>
<p>Some monitors have <strong>USB UP</strong> wrote on them, which represents the USB Upstream port, and <strong>USB IN</strong> represents the USB Downstream port.</p>
<p>Upstream and Downstream is the USB hub feature of the monitor. It eliminates the need to run multiple cables from your monitor desk to your computer. Multiple cables connect to your monitor, and a single USB cable connects to your computer.</p>

Any two pieces of hardware may require some kind of interface to communicate with one another. This connector is known as a port in a computer system. So, in general, a computer/laptop port is nothing more than an interface or point of connection between peripheral devices (input/output devices) and the computer. Technically, they are just slots on your motherboard.
A computer port is also known as a communication port because it is in charge of communication between the computer and peripheral devices.
Functions of Laptop or Computer Port:
The primary function of this port is to allow one hardware component to be plugged into another in order for them to communicate with one another.
Computer|Laptop Port Shape and Size
Ports come in a variety of shapes, including round (PS/2), square (RJ 45), rectangular (FireWire, USB, and so on), and trapezoidal (DB-25 printer port, DB-9 serial port). However, in general, this shape does not differ from one vendor to the next.
Ports on a laptop or computer can be divided into two groups based on how the port allows communication. Serial ports and parallel ports are the two types of ports.
Now, let’s describe each of them:
Table of Contents
- Computer | Laptop Port
- Functions of Laptop or Computer Port:
- Computer|Laptop Port Shape and Size
- Serial Port
- Parallel Port
- PS/2 Port
- USB Port
- eSATA Port
- Firewire Port
- Thunderbolt Port
- Video Ports
- Ethernet Port
- SD Card Reader
- microSD Card Reader
- Audio Jacks
- Power Port
Serial Port
A serial port is an interface that allows serial hardware devices to communicate with a computer by sending one bit of information at a time over a single communication line.
Example: Used for older computer mouse (before ps/2 port and USB port are invented), older keyboard, external modems, and PDAs.It is less commonly used in today’s tech industry.
fig: serial port Note ! In today’s modern computer/laptop we do not find a serial port, it is already replaced by a USB port.
This port is located on the back panel of your CPU cashing box, where serial ports are either two male DB-8 connectors (8-pin connector type) or one DB-9 and one DB-25 connector. A desktop computer has it, but a laptop does not. The real issues with serial ports are limited bandwidth and ports.
Parallel Port
Parallel Port is an interface through where parallel hardware devices communicate with the computer by transmitting multiple bits of information at a time over multiple communication lines (or wires).
Example: Used for scanners and printers, external CD ROM, Zip Drive, external HDD, tape backup devices, etc.
fig. parallel port
Note !
In today’s modern computer/laptop we do not found a parallel port, it is already replaced by a USB port.
Let’s look at how data flow in both serial and parallel port with the below image.
PS/2 Port
PS/2 port stands for Personal System/2 port which was introduced to the world by IBM in 1987. It was used by an older PC for connecting a mouse or keyboard to an IBM PC-compatible computer system. It is round and consists of 6 pins. In most cases, the green color PS/2 port is used by mice and the purple color PS2/ is used for the keyboard.
- Hotplugging: It is said that it is a bad practice of removing the mouse and keyboard cable from the ps/2 port while the system is running. It may damage the system.
- Durability: PS/2 connectors are not intended to turn on and off regularly, which may bring about twisted or broken pins if not inserted in the proper orientation.

USB Port
USB stands for Universal Serial Bus. The USB port can transfer data at a much faster rate than serial and parallel port.
Type-A USB Port
It is a common type of USB port present in general personal laptops and desktops. It comes with 4 pins connector and is available in various types and versions. They are USB 1.1, USB 2, USB 3.0 (now called USB 3.1 Gen 1), and USB 3.1 Gen 2. Although all those have 4 pins we can identify each of them by color.
(10 times faster than USB 2.0)
Type B USB Port
USB Type B is not as common as Type A. The Type B connector is nearly square in shape. It is frequently used when connecting printer cables, scanner cables, USB hub cables, and external hard drive cables to computers.
fig. Type B USB Port
Type C USB Port
This is the future of USB port and is expected to replace both Type A and Type B port and many laptops and mobile companies are taking it as a standard USB port. The data transfer rate is 10 Gbps to 20 Gbps. It is much slimmer and smaller with 24 pins which makes it capable of handling high current and speeds. Every USB Type C port is a reversible plug which means they can be plugged upside down if you want. Some of its types are: USB 3.1 Gen 2 and USB 3.2
fig. Type C USB Port
Note ! Both USB 3.1 Gen 2 (10Gbps) and USB 3.1 Gen 1 (5Gbps) are backward compatible with existing USB 3.0 and USB 2.0
USB 3.1 Gen1 is SuperSpeed USB and USB 3.1 Gen2 is SuperSpeed+ USB. Also, USB 3.1 Gen2 is thinner than USB 3.1 Gen1.
eSATA Port
eSATA is an external Serial Advanced Technology Attachment port that can supply signal (but not power) to external storage devices such as hard disk drives. You can connect external drives to your computer or laptop if you have an external drive with an eSATA connector and your computer or laptop has an eSATA external port. It resembles the USB Type-A port in appearance. It has a maximum bandwidth of 6 Gbps, which is faster than USB Type 3.0’s maximum bandwidth of 5 Gbps. In the past, laptops and PCs were used. It is about 2m in length and thicker than SATA.

Is eSATA and SATAe are same ?
Ans: No. eSATA stands for external SATA and SATAe stands for SATA Express. They have different connectors and ports.
e SATAp

eSATAp is power over eSATA. eSATAp is the combination of eSATA and USB ports. You can plug in a USB connector as well as eSATA connector in the eSATAp port.eSATAp can supply power at 5 V and 12 V.
Firewire Port
IEEE 1394 port is another name for a Firewire port. There are two kinds of Firewire ports: Firewire 400 and Firewire 800. It, like USB, was a popular connector for connecting external devices to your computer, such as a hard drive, printer, scanner, camera, and so on. It has a transfer rate of up to 480 Mbps.
Before 2011 AD, most of the Apple systems used to have Firewire port, but from 2011 AD they started replacing Firewire Port with a much faster Thunderbolt Port.
Thunderbolt Port
Thunderbolt is a hardware interface developed by Intel in a joint effort with an apple that allows you to connect external peripherals to your computer. It is a combination of two high-performance standards, DisplayPort and PCI Express(PCIe) into a single cable.
What does a Thunderbolt port look like?
Ans: Just near to thunderbolt port there is a lightning bolt icon as shown above.
Up to now, we have 3 types of the thunderbolt:
Thunderbolt 3 port is rising. It has a bandwidth of 40 Gbps which is double of Thunderbolt 2 and 4 times of USB type c, it also allows up to 4 lane PCIe 3.0 and 8-lane display port along with USB 3.1 Gen 2 10 Gbit/s
Can I plug the USB into the Thunderbolt 3 port?
Ans: You can plug USB Type C devices into the Thunderbolt 3 port of your laptop or computer.
Video Ports
a) VGA Port
VGA stands for Video Graphics Array. It is much popular in older CRT monitors. It is analog in nature so its image quality degrades while converting from analog to digital and vice versa, also analog signal is more prone to noise. It has 15 pins, with 3 rows of 5 pins. It does not have hot plugging features.
b) DVI Port
DVI Stands for Digital Visual Interface. It is the successor of the VGA port.it is designed to give high-quality audio-video to LCD monitors. It has hot plugging features and it has three types of cable.
Both DVI D and DVI I comes in two formats:
c)HDMI Port
HDMI stands for High Definition Multimedia Interface. It was developed in 2002 AD. Its look is similar to the USB port but it is comparatively larger in size and wire number.HDMI is used for sending and receiving high-definition audio-video signals through a single HDMI cable to the broad ranges of devices like digital TV, computer, projector, gaming console, mobile devices, digital camera, blu ray, Ultra HD player, cable box, etc.
Some HDMI versions are listed below:
Has added high-quality DVD audio.
Has electrical spec and mechanical changes.
Is Thunderbolt better than HDMI?
Ans: When connecting your TV or monitor to your laptop, then it’s better to connect with HDMI as HDMI is the preferred connection type capable of transferring HD audio and video with a single cable. But thunderbolt can provide more bandwidth than HDMI so if you have thunderbolt you can use it.
d. Display Port
The display port is designed to replace both the VGA port and DVI which we will discuss later. click here.
e)S-Video Port
S-Video is an alternative method for transferring video signals. It is a circular port with 4 pins or 7 pins. S-Video has the capability for displaying your video or presentations on a larger screen(TV, projector) than the built-in display of your laptop. But note that S-Video does not transmit audio, but you can use your laptop speakers to listen to the sound from a video.
Ethernet Port
Ethernet Port is also called RJ-45 (Registered Jack -45) port or LAN port or just network port. It allows your computer and laptop to connect to a network using an RJ-45 cable connection.
If your laptop or computer doesn’t have a wifi adapter installed then you can use an ethernet port for connecting to the outside world for internet access.
SD Card Reader
It is also called a memory card reader in the tech market. It is available on both PC and mobile. It is used for transferring data to and forth between computer and SD card. You just have to insert a memory card into the SD card port then it will display on-screen as a separate drive.
microSD Card Reader
microSD Card Reader ports and SD Card Reader Ports are very different and are much smaller than SD Card.microSD Card Reader reads tiny microSD memory cards as shown below.
Audio Jacks
Generally, Laptop has two audio ports, a green color audio port is for the headphones and a pink color audio port for the microphone(or mic) and today’s laptop comes with a single audio port/jack.
The standard size of the Headphone jack is 3.5mm.
Power Port
As laptops are portable devices so it has to be charged time and again. So, we use a power port for charging laptop batteries. Connect one end to the AC power socket and another end to the power supply unit.
