do all lcd monitors have hdmi ports manufacturer
Computer monitors have quickly evolved over the years allowing for monitors with greater features, innovative user interfaces, as well as better displays. However, how do current monitors fair when it comes to what’s actually in the box? Which brings us to the question Do Monitors Come With HDMI Cables?
Most computer monitors do come with HDMI cables, however, not all of them. The manufacturer will typically state whether or not it provides an HDMI cable in the product description section of its website.
Let’s now take a quick look at some of the top monitors in the market & whether or not they provide a free HDMI cable in the box, as well as some top uses for an HDMI cable. Let’s dive in!
The majority of monitors do come with HDMI cables, however, not all of them do. Most manufacturers state on their website whether or not an HDMI cable is included in the box. So be sure to check the manufacturer’s official website to see whether or not they provide an HDMI cable.
Probably one of the top uses of an HDMI cable is connecting your laptop to a monitor. This makes a huge difference when it comes to productivity as it allows you to utilize the larger screen & have multiple browsers open without having to minimize & maximize the browser on your screen to get through information.
HDMI cables can also be a great option when you want to utilize your TV’s enhanced viewing experience & transmit your favorite shows from your laptop to your TV. This is particularly great if you don’t have cable or if you want to just pop a movie from a streaming service such as Netflix or Hulu to your Screen without having to download the app.
Another great use for an HDMI cable is connecting a soundbar to your TV. This allows for a much better listening experience since most smart TVs aren’t equipped with large speakers. So adding a soundbar to the mix will definitely have a positive impact on your viewing experience.
Last but not least an HDMI cable can also be used to connect your monitor or TV to a streaming Box, allowing you to stream popular movies & TV shows through popular streaming services such as Netflix, Hulu, Apple TV…etc
Some computer monitors in the market are equipped with built-in speakers, however, the majority don’t have speakers. You can check whether or not your monitor has speakers by checking to see if it has an audio input jack at the back of the monitor if it does then your monitor does have built-in speakers.
Most computer monitors don’t have cameras, the reason being is adding a camera will require the manufacturer to spend additional resources on functionality as well as the camera itself. This will increase the overall price of the monitor for resources spent on functionality & the hardware without providing much value to the monitor itself.
So there you have it, whether or not your monitor will be provided with an HDMI cable is simply dependent on the type of monitor. However, the majority of monitors in the market do provide you with an HDMI cable. However, to ensure your desired monitor provides an HDMI cable check the official website of the manufacturer to see whether or not an HDMI cable is provided in the box.
However, plenty of wired connections are still essential, and ports remain a reliable connection solution. For example, a quick look at your monitor or computer CPU will show you various ports, such as USB, Thunderbolt, and even the older VGA.
That said, the last decade or so has seen HDMI become the common standard for proprietary connection interfaces, making it one of the quickest and most reliable ways to connect devices.
The answer is as simple as checking the ports on the back of your monitor. Depending on the unit you have, your monitor may feature anywhere from a couple of HDMI ports to several interfaces, including DisplayPort and even VGA. However, modern monitors that feature high refresh rates and resolutions tend to feature the latest HDMI port, HDMI 2.1.
If you’re interested in learning more about HDMI ports and monitors, this article will detail the HDMI ports, monitors, why you should use them, and anything else in between.
An abbreviation for High Definition Multimedia Interface, the HDMI was first released back in 2002. It was also developed by several top manufacturers, including Sony, Toshiba, and Panasonic, to name a few.
During the early 2000s, VGA ports (the standard at the time) were starting to show their age. As they are analog cables that rely on electrical surges, VGA cannot transmit both audio and video, and its max resolution is only 1080p.
As a result, HDMI was developed as a replacement. However, it would take a few years and the switch to digital cables for HDMI to be fully adopted, making it the new standard for connections.
The newest HDMI version is 2.1, capable of transmitting 8K and 10K resolutions for the most high-end set-ups. It also enables a bandwidth of up to 48 Gbps, making it the fastest cable currently available in the market.
In terms of connections, a monitor doesn’t need to use an HDMI port for connection. It’s also not a requirement, as a manufacturer can use plenty of other connectivity solutions.
As a matter of fact, quite a few do not offer HDMI. In such cases, the monitor may instead opt for only DVI, USB-C, or DisplayPort connectors, and it will still function just like any other monitor.
Furthermore, plenty of other options even exceed that of HDMI’s capabilities. For example, monitors that use DisplayPort 2.0 ramp things up by having a bandwidth of 77.37 Gbps, meaning that it can output 16K resolution at 60Hz, provided you have the GPU for it.
Additionally, DisplayPort 2.0 even enables dual-monitor support at higher resolutions and faster refresh rates. For example, it can easily output dual 8K displays at 120Hz. For this reason, you will find gaming-oriented monitors and PCs using DisplayPort instead of HDMI.
However, the reason why plenty of monitors and TVs use HDMIs is simply that it’s the standard, and plenty of consumers that utilize these products expect an HDMI port or two.
On that note, more TVs use HDMI, while high-end monitors used in gaming-oriented set-ups often use the latest DisplayPort version, as these are more capable and offer faster refresh rates.
Given that you’re using the standard HDMI size (there are also mini-HDMIs, though they are less common), an HDMI port looks a bit similar to a USB port, albeit with a more trapezium shape. It’s a recognizable outline and, often, HDMI ports either have a label that says “HDMI” or sports its logo up top.
To start, take your male HDMI cable and locate your monitor’s female HDMI port. If it doesn’t have one, you can either use a DisplayPort cable or an adapter. Either way works.
Assuming your monitor has an HDMI port, insert the cable in the port and secure it. Then, locate the other end of your cable and do the same thing in your GPU’s HDMI port.
Suppose the cable has no problems and you’re using the correct HDMI version compatible with your GPU and monitor. In that case, you should be able to enjoy your choice of media in the highest resolution properly.
Otherwise, using an older HDMI cable will still work, but it will only transmit the resolution it’s capable of. For example, using an HDMI 1.4 cable on a monitor that supports 144Hz will only give you 30-60Hz.
One great example is the SecurOMax HDMI cable, which features a gold-plated connector that supports up to 4K UHD. It also comes with a braided cable and is quite affordable.
There’s also the Belkin HDMI 2.1 Ultra High-Speed cable, which future-proofs you as it supports 8K resolutions, 4K at 120Hz, and even features a braided jacket for extra stability. Utilitywise, this cable is best used in game settings.

If you’re looking to connect your PC to a high refresh monitor, you should locate the HDMI port on the back. The same goes for any modern television, as HDMI is the standard used for most consumer electronics.
Best of all, HDMI ports are backward compatible and should work with any HDMI cable. However, if you want to take advantage of better graphics, we suggest future-proofing yourself with the latest version of the HDMI.
An HDMI monitor is a monitor that is connected through a high-definition multimedia interface (HDMI) port. The connection is generally the first obstacle you encounter when buying a monitor. Most LCD monitors use VGA and HDMI ports, with the latter being somewhat more important. This is because the image’s definition depends on it.
For most modern home entertainment devices, flat-screen TVs, and monitors, for example, HDMI is the standard connection interface. In the case of DVI, on the other hand, the signal is transmitted in digital format, which means that it maintains the original quality.
HDMI ports have completely taken over the current market because this system allows uncompressed and encrypted transmission. This means that the connection is made directly, improving the quality of two factors in the process. Both high-definition video and multichannel digital sound are made possible.
The audio is transmitted through eight channels without stopping during compression, while videos do not need to be compressed and therefore keep their original quality.
Various versions have improved HDMI monitors over time. Simultaneously, the cables have evolved to adapt and offer new functions. Knowing the various versions helps you to make a comparison between different HDMI monitors.
If you want to make the most of your monitor, you should opt for an HDMI model. Visual enhancements are a vital aspect for anyone looking for the optimal experience. Before purchasing the best HDMI monitor for you, you will have to evaluate a series of key criteria. If you pay attention to them, you will make the right decision and find the best HDMI monitor for your personal needs.
Nowadays, there are many different ways to connect a monitor. While HDMI monitors are increasingly gaining popularity, you still have access to other methods. They range from the classic VGA connection to modern USB-C systems that can reach speeds of up to 40 Gbps.
With the DisplayPort interface, all you have to do is connect the ports and start enjoying your new monitor. Many models currently have a node with several USB connectors. While some integrate speakers, audio inputs, and outputs in the design, multimedia monitors stand out for offering quality solutions in that sector.
A wall-mounted monitor allows you to have more space on your desk for other items. The ergonomic capacity of your monitor is another key criterion. Make sure that the model you buy has a base that can be adjusted and rotated to your liking.
You may also be interested in the Low Blue Light technology. This feature protects your eyes from continuous exposure to blue light by focusing on reducing the brightness of blue tones, which converts images into warmer tones. You can even find monitors with customizable lighting systems.
Several key differences exist between HDMI monitors and previous systems. First of all, the usual DVI (Digital Visual Interface) connection doesn’t support audio signals. This means that you would need an auxiliary cable for the sound. In addition, HDMI supports higher resolutions. The DVI was designed to connect to the PC, while the HDMI is able to connect to any audiovisual device.
The HDMI also has a protection system called HDCP (High-Bandwidth Digital Content Protection) that allows to safeguard the data transmission, hence preventing unauthorized copies. Its aim is basically to avoid plagiarism in the output of a source. To do so, a transmitter verifies the receiver’s authorization and encrypts the material.
The HDMI connection isn’t exclusive just yet, and there are still versions and models that include other types of connectors. This is why various adapters have been created to allow you to keep using your devices. In the following paragraphs, we explain the most common types for you.
While most current devices integrate HDMI outputs, you may have a monitor or projector that only has a VGA input. This could prevent you from connecting your two devices. With an HDMI to VGA adapter, you can convert the signal and enjoy high-quality audio and video.
This adapter is particularly useful for linking HDMI monitors to another portable device. With this cable, you will be able to connect your smartphone or tablet without having to configure them. These adapters tend to have longer life cycles, and they have already been upgraded with the
We have talked about HDMI monitors, cables, and adapters. But what if all this could be done without cables? This is now possible. Wireless systems can connect to the monitor port and to the device you want to link it to. The transmission of the content keeps its quality and doesn’t require compression.
It’s important for you to know and understand the different computer monitor connection types so you can choose the best for your monitor. They include VGA, HDMI, Display port, DVI, Thunderbolt, and SDI.
With the development of newer technology manufacturers have developed better and advanced connectors. With those comes a better resolution, which makes the monitors, like the ones in this post, easy on the eye. Let’s take a look at the various types of ports you might have come across online.
Because VGA and some versions of the DVI connector Interface are suited for analog data, the quality of the video may become degraded at higher resolutions or at longer cable length. A VGA cable will typically have a blue color connector.
It was mainly used with the now-extinct CRT monitors (see "What is a CRT Monitor?"), but you can still find VGA DVI connector ports on some new hardware equipment such as LCD monitors. However, VGA DVI-ports are slowly being phased out by digital and modern connections. Latest top-shelf gaming monitors we reviewed and cutting edge vertical monitors here have all ditched the analogue in favor of digital ports.
DVI stands for the digital visual interface. It was developed in 1999 to provide uncompressed, high-quality video connection to LCD monitors. A DVI connector will typically have a white color adapter. There are three used types of DVI port;
DVI -D is another version of DVI connector ports where the ‘D’ stands for digital. It’s used only to send digital signals. DVI –D is much more common compared to DVI –A but you cannot use DVI –D cable with a DVI –A equipment or vice versa.
A DVI –D dual link connector uses a pin arrangement of a single flat pin and three solid rows of eight pins each. It has a maximum resolution of 2048 by 1536 at 9.9 Gbps. A single-link cable sends one signal at a time whereas a dual-link cable can send two signals, allowing for higher data flow at larger resolutions.
There’s also another version of the DVI standard called DVI –I, where the ‘I’ stands for integrated which means it can carry both analog and digital signals. This means that you can use it with DVI –D or DVI –A.
Dual-link DVI uses a pin arrangement of a single flat pin surrounded by four pins and three solid rows of eight pins each. It’s capable of a maximum resolution of up to 2560 by 1600 and double the video bandwidth at 9.9 Gbps.
HDMI stands for High definition multimedia interface. It’s probably the mostbroadly used HD signal interface for transmitting both high-definition audio and video over a single cable.
HDMI cables - see also "What is HDMI?" post - are widely used today in different electronic products such as a monitor, Graphics card, TVs, computers, projectors, mobile devices, Xbox, video cards, PlayStation, and many more. Over the years, HDMI has been connected to more devices and has become the standard for corporate and commercial devices.
HDMI cable connectors are one of the best standards for high definition in customer electronics delivering crystal clear video as well as audio signals. Furthermore, in 2017, HDMI 2.1 was released which added another channel for network communication together with these qualities - see best HDMI 2.1 monitors, too.
There’re mini and micro versions of Hdmi out there on the market too, as smaller and smaller devices such as our smartphones and tablets increasingly become our HD AV sources.
It was developed by VESA (Video electronics standard association). It can also connect to the older DVI, VGA, and HDMI ports using adapters or HDMI DisplayPort converters. It has multi-monitor capabilities which allow you to use multiple computer monitors by connecting them in a daisy chain connection or configuration.
This is a version of the DisplayPort that was introduced by Apple Company in 2,008. It uses the same technology as DisplayPort DP but it"s smaller in size or mini.
Its daisy chain connection makes Display Port more focused on computer use than other devices such as television due to its ability to connect a chain of monitors. Here are some of its features;Mini Displayport 2.0 supports 4k at 240 hertzMini Displayport 1.4 support 8k at 30hertzDisplay Port 2.0 supports 8k at 85 hertzBoth 4k and 8k is supported
The SDI is a simple coaxial cable that can run up to about 300 meters before losing video signal strength. Its digital connections use a BNC connector and almost all video security cameras use it to transfer motion pictures.
Both DisplayPort and HDMI have different features that make them popular and widely used in a computer. However, I find the DisplayPort to be far more superior to HDMI due to its exceptional features and ability to accommodate future technology.
Here are some of the features and capabilities that differentiate HDMI and DisplayPort from the rest;Both HDMI DisplayPort connectors have corners at the sides that are used to prevent the user from inserting the connectors incorrectly.The DisplayPort connector has a locking mechanism that keeps the cable connected to your display equipment whereas HDMI doesn’t have a locking mechanism.In terms of speed, the DisplayPort 2.0 has a maximum transmission of up to 80 Gbps whereas HDMI cable 2.1 has a maximum transmission of up to 48Gbps.Both cables support 4k and 8k
Make sure you understand which cable is required so as to meet your needs. HDMI is best for video and audio signals. Use it for PC and TV connections.
If you are looking for high refresh rates either for gaming or video editing, DisplayPort is the cable of your choice. It is also great for audio and video signals and transmits up to 144HZ - see "Which Cable Do I Need for 144Hz?" post.
HDMI and DisplayPort can support up to 8k resolution but you should check the specifications of the cable before purchasing it. If you want a cable connection at 1080p, DVI and VGA will be just fine.
The most common types of monitor ports and cables are HDMI, DisplayPort, and USB-CTM (see What is USB-C?), which are found on the majority of modern displays. However, legacy interfaces such as VGA and DVI are also available in case you need to connect to older devices.
DVI is an acronym for Digital Visual Interface and provides a noticeably sharper, higher-quality image than VGA. It is a one-of-a-kind connector in that it is capable of carrying both digital and analog signals. Additionally, DVI is easily convertable to other standards such as HDMI and VGA.
HDMI is the most frequently used connector for televisions. However, if you want to connect a computer to your television (or if you"ve purchased a new computer monitor), your options typically include HDMI, DisplayPort, DVI, and occasionally the venerable VGA.
The majority of computers include VGA, DVI, and HDMI ports, while some laptops only include thunderbolt, USB ports, and an HDMI adapter. Therefore, if both your monitor and computer have a VGA connection, connect the two using a VGA cable.
Yes. DisplayPort cables have a higher data transfer rate than HDMI cables. With a higher bandwidth, the cable can transmit more signals simultaneously. This is primarily beneficial if you intend to connect multiple monitors to your computer.
A close look at the video input interfaces used in LCD monitors. With the emergence of a new generation of interfaces, growing numbers of LCD monitors feature multiple and different interfaces. Image quality and ease of use are likely to depend on how well the user knows and uses the unique characteristics of each interface when connecting the appropriate devices.
Note: Below is the translation from the Japanese of the "IT Media LCD Display Course II, Part 2," published on December 16, 2008. Copyright 2011 ITmedia Inc. Information about Mini DisplayPort was added to the English translation.
Driven by demand for higher-resolution monitor environments and the proliferation of high-definition devices, the types of video input interfaces ("interfaces" hereinafter) found in LCD monitors continue to proliferate. More than likely, significant numbers of users encountering LCD monitors incorporating multiple input systems have wondered what to connect to which terminal. In this article, we"ll discuss, one by one, the main interfaces used today. But first, let"s give an overview of the types of interfaces available.
The interfaces for LCD monitors designed for use with PCs can be grouped into two categories: analog interfaces, carryovers from the days of CRT monitors, and the digital interfaces developed more recently. An analog interface involves the additional steps of conversion of digital signals within the PC to analog signals for output and the conversion of these analog signals back into digital form by the LCD monitor receiving the signal. This series of actions can degrade image quality. (Image quality also depends on the quality of the route used in converting from analog to digital.) A digital interface offers superior image quality, since it transmits digital signals without conversion or modification.
LCD-monitor interfaces also can be grouped by differences in the devices connected. Major categories here are inputs from PCs and inputs from audio-video (AV) devices. PC input generally involves one of the following five interface types: D-Sub for analog connections; DVI-D for digital connections; DVI-I, which is compatible with both analog and digital connections; and HDMI and DisplayPort, representing the new generation of interfaces for digital connections. Other more recent adapters input and output PC RGB signals and LCD monitors using USB as a video input interface.
The main AV input interfaces are composite video, S-Video, component video, D1 – 5, and HDMI. All of these other than the new HDMI standard use analog connections. As with PC input, a digital HDMI connection generally provides better image quality for AV input than the various analog connection interfaces.
It"s worth noting that while HDMI was designed for use with AV input and output, the standard also supports PC input and output. LCD monitors incorporating HDMI ports include some that support PC input officially and others that—whether or not they can display PC input—do not support PC input officially.
Known officially as D-Sub miniature, D-Sub is not exclusive to display use. It"s also used for serial-port, parallel-port, SCSI, and other connectors, with the number of connector pins depending on the purpose of use. However, these connector standards are rarely if ever found in PCs now for general-purpose personal use, most such applications having migrated to USB.
When used as a monitor interface, a D-Sub port is also known as a VGA port, an analog connection standard that"s been around for some time. The connector is a DE-15 connector with 15 pins in three rows, often referred to as a "mini-D-Sub 15-pin" or "D-Sub 15-pin" connector. (Some connectors omit unused pins.) D-Sub is currently the most widely used monitor interface, compatible with very large numbers of PCs and LCD monitors.
A D-Sub female connector (photo at left) installed on the monitor side and a D-Sub male connector (center photo) on the cable side. A D-Sub cable features a screw on each end of the connector that can be turned by hand to prevent unintended disconnection (photo at right).
Keep in mind that there are two types of mainstream DVI-D digital connections: single link and dual link. For a single-link DVI-D connection, the maximum resolution that can be displayed is 1920 × 1200 pixels (WUXGA). Higher resolutions (such as 2560 × 1600 pixels) require a dual-link DVI-D connection providing double the bandwidth of a single-link DVI-D (7.4 Gb/second or higher). To use a dual-link DVI-D connection, the DVI-D input on the LCD monitor side, the DVI-D output on the PC side, and the DVI-D cable must all be compatible with the dual-link DVI-D standard.
DVI-I, the other DVI standard, can be used with both digital and analog connections, depending on the monitor cable used. Since a DVI-I analog signal is compatible with the D-Sub standard, an analog connection can be formed by using a monitor cable with a D-Sub connector on one end and a DVI-I connector on the other. Depending on the cable and the connectors on the PC side and on the LCD-monitor side, it may also be possible to use an adapter for connecting a DVI-I connector with a D-Sub connector.
A DVI-D female connector installed on the monitor side (photo at left) and a DVI-D single-link (18-pin) male connector installed on the cable (center photo). As with D-Sub cables, a DVI-D cable can be secured into place by turning the screws on either end of the connector (photo at right).
Monitor cables with DVI-I connectors on both ends were available at one time. These are rare today, since this configuration made it difficult to determine whether the connection was digital or analog and generated frequent connection issues. Having DVI-I connectors on both the PC side and the LCD monitor side can lead to confusion. In such cases, the ideal configuration is a digital connection made with a DVI-D cable.
As the latest digital interfaces, the High-Definition Multimedia Interface (HDMI), DisplayPort, and Mini DisplayPort have attracted considerable attention. All standards offer the capacity to transfer both audio and video signals digitally using a single cable; all offer easy cable attachment and removal.
The shapes of HDMI, DisplayPort, and Mini DisplayPort connectors resemble that of a USB series-A connector (on the side of the USB host, such as a PC). The connectors lack screws, allowing the cables to be readily inserted and removed. (The disadvantage: This makes it easier to dislodge a cable connection if a hand or foot catches on the cable.)
At left is an HDMI (type A) female connector; in the middle is a DisplayPort female connector; at right is a Mini DisplayPort female connector. The HDMI connector has 19 pins. The DisplayPort and Mini DisplayPort connectors have 20 pins and an asymmetrical (left to right) connector. (The HDMI standard also defines a 29-pin type-B connector compatible with resolutions exceeding 1080p.)
The HDMI, DisplayPort, and Mini DisplayPort standards also are compatible with the High-Bandwidth Digital Content Protection System (HDCP). A technology intended to protect copyright on digital content, HDCP allows authorization of both output and input devices before video is displayed.
Another feature is that HDMI, DisplayPort, and Mini DisplayPort video signals can be converted back and forth with the DVI-D standard, a PC digital interface. Using the appropriate conversion adapter or cable, we can output video from a DVI-D, HDMI, DisplayPort, and Mini DisplayPort connector and input to any of these options. Currently, however, this implementation appears to be imperfect: In certain cases, input and output devices are not completely compatible (i.e., video does not display).
While HDMI, DisplayPort, and Mini DisplayPort each can transmit both audio and video using a single cable, DVI-D can transmit only video and requires separate input/output ports and cables for audio. For this reason, when converting between the DVI-D and HDMI, DisplayPort or Mini DisplayPort standards, only video can be transmitted over a single cable. (Some products can transmit audio from the DVI side via a conversion adapter.)
Now a standard interface for devices (primarily televisions and recorders), HDMI was established in December 2002 by Sony, Toshiba, Thomson Multimedia, Panasonic (formerly Matsushita), Hitachi, and Philips, led by Silicon Image. HDMI video signals are based on the DVI-D standard, a digital RGB interface used in PCs, to which audio transmission and digital rights management (DRM) functions were added. HDMI was intended mainly for use as a digital video and audio interface for home electronics and AV equipment.
An HDMI (type-A) female connector (photo at left) and male connector (center photo). The compact HDMI cable is easily connected and disconnected, just like a USB cable (photo at right). HDMI cables come in two types: Standard (category 1), denoting those that have passed 74.25 MHz in transmission-speed tests, and High Speed (category 2), denoting those certified for 340 MHz. A High Speed cable is recommended when using high-definition signals such as 1440p.
In discussions about HDMI, the subject of functional differences between versions of the HDMI standard is unavoidable. The table below summarizes the major differences. There are significant differences in functions implemented between HDMI versions through version 1.2a and HDMI versions 1.3 and above.
Since HDMI versions are backward compatible, we can still input and output video and audio if the output side is compatible with version 1.3 or above and the input side with version 1.2a or below. However, if the output device uses functions implemented in version 1.3 or higher, these functions will be canceled on input devices that comply with version 1.2a or earlier.
Incidentally, while HDMI 1.3 incorporates standards such as the wide color-gamut standard xvYCC and Deep Color, which can handle color data at greater than 24 bits, these specifications are elective. A version number such as 1.3 is merely the number of the applicable technical specifications; manufacturers can choose what functions to include, depending on the specific product. For this reason, even a product advertised as HDMI 1.3a compliant may not feature all of the functions supported by HDMI 1.3a.
1 Consumer Electronics Control (CEC): A signal used for control functions between devices connected by HDMI; used in technologies such as Sharp"s Aquos Familink , Toshiba"s Regzalink, and Panasonic"s Viera Link.
Formally approved in May 2006, the DisplayPort standard is a new standard released in May 2005 by the Video Electronics Standards Association (VESA) of the United States, an industry organization that establishes standards for PC-related interfaces. As a video interface promoted by VESA, a constituency composed mainly of PC and monitor makers, it is designed to succeed the DVI and D-Sub standards as a PC interface. However, there"s no reason it can"t also be used in AV equipment.
DisplayPort female (photo at left) and male (center photo) connectors. Although a DisplayPort cable resembles an HDMI cable, it has two hooks at the top of the connector to make it harder to disconnect accidentally (photo at right).
With a maximum transmission speed of 10.8 Gbps, compatibility with resolutions of up to 2560 × 2048 pixels or higher, color depth of 48 bits (16 bits per RGB color), and a maximum refresh rate of 120 Hz (120 fps), its basic video interface specs are close to those of HDMI. However, unlike HDMI, which transmits data for RGB video signals and clock signals separately, it sends all video and audio to the destination device through a serial connection, split into micro-packets called transfer units.
Since DisplayPort is a serial interface like PCI Express that generates a clock from the data instead of using external clock signals, data transmission speeds and functionality are easily improved. In addition, since DisplayPort employs a configuration wherein the LCD monitor is operated directly, it makes it possible to reduce the numbers of components. Another benefit is its ability to transmit signals over distances of up to 15 meters.
In the DisplayPort standard, the output side is defined as the source device and the input side as the sync device. Under this configuration, the source and sync devices communicate with each other, making it possible to automatically adjust transmission to the optimal resolution, color depth, and refresh rate. Audio and video data can be transmitted through a combination of single, double, or quadruple channels called lanes, and two data rates (1.62 Gbps and 2.7 Gbps). The minimum configuration is a single lane at 1.62 Gbps; the maximum is four lanes at 2.7 Gbps each for a total of 10.8 Gbps.
The audio formats supported and other attributes are important elements of sync devices. For audio, compatibility with 16-bit linear PCM (32/44.1/48 kHz) is required. Other formats are optional. Still, the standard is compatible with formats up to high-definition audio such as Dolby TrueHD and DTS HD. For color information, compatibility with RGB, YCbCr (4:2:2), and YCbCr (4:4:4) is a requirement.
One major difference apparent when we compare HDMI and DisplayPort is the presence or absence of licensing fees. Implementing HDMI in a product requires manufacturers to pay a licensing fee of $10,000/year, while HDCP implementation requires a separate licensing fee of $15,000/year. These licensing fees entail significant costs for manufacturers. When product pricing reflects these costs, they can impact ordinary users to a greater or lesser degree. A more familiar example is the HDMI cable, which is also subject to a licensing fee, making it more expensive than other AV cables. (Note that the licensing fee is not the sole cause of higher prices; quality requirements and other factors also drive up prices.)
DisplayPort requires no licensing fees other than that for HDCP, making it more attractive and easier for manufacturers to adopt. Progress in mass production will likely lead to price advantages for ordinary users as well. Still, HDMI is clearly the current mainstream digital interface for products like AV equipment and videogame consoles. DisplayPort, even if standardized under the leadership of PC makers, is unlikely to take its place. With growing support for DisplayPort among vendors of graphics chips for use in PC environments and growing numbers of compatible products, including the MacBook, use of DisplayPort is projected to expand.
While component video ports offer higher quality and greater benefits than most other types of analog video input, they also entail inconveniences, including more troublesome connections (since they use three connectors) and greater space requirements on devices equipped with such ports. Additionally, they are incapable of transmitting control signals. In Japan, the D-Terminal standard, formulated by the Japan Electronics and Information Technology Industries Association (JEITA, known at the time as the Electronic Industry Association of Japan, or EIAJ), which features its own improvements on these points, has entered widespread use.
A D-Terminal connector combines the three types of component video signals into a single cable and is easier to connect. It also embeds a control signal to identify scanning lines, scanning method, and aspect ratio. (In passing, it"s called a D-Terminal only because its connector is shaped like the letter "D"; the "D" does not mean "digital." Signals flowing through the D-Terminal and the connecting cable are analog.) The table below gives the types of D-Terminals (D1 – 5) and corresponding video formats. While many products feature D5 terminals, which are compatible with 1080p video, this is not specified in the official JEITA standard.
Let"s consider S-Video and composite video ports. Video consists of a brightness signal and a color signal, combined to create a composite video signal. A composite video port transmits the composite video signal as is; an S-Video port transmits the composite signal separated into a brightness signal and a color signal. Since less processing is needed to combine and separate the brightness and color signals, an S-Video port provides higher picture quality than a composite video port.
Additionally, there are two types of S-Video ports: S1, which can identify video with aspect ratios of 4:3 and 16:9; and S2, which can identify "letterbox" video with black bands above and below, to display 16:9 aspect-ratio video on 4:3 aspect-ratio monitors. A display device receiving video with a 16:9 aspect ratio or letterbox video performs the appropriate scaling to display the correct aspect ratio.
S-Video and composite ports are capable of handling video up to standard-definition NTSC (480i). They are likely to be phased out gradually in the future, except for applications requiring the connection of older video equipment such as VHS video decks or DV cameras.
Let"s conclude by returning to the subject of PC environments. Some recent products use USB ports for PC display output. While USB was not originally intended as a display interface, demand has emerged for an easier way (easier than using a D-Sub cable) to set up multi-monitor environments, particularly for laptops and low-priced netbooks.
Most such products are adapters, which connect to the PC using USB and feature DVI-D or DVI-I connectors on the output side. These are then connected to LCD monitors. After the user installs a device driver, the PC recognizes the adapter as a monitor adapter. Users can create a multi-monitor environment in Windows by activating the secondary monitor connected to the adapter in Display Properties. In terms of display performance, these adapters are not well suited to uses that require high-speed response; they are associated with slight delays in reflecting mouse or keyboard operations.
A small number of LCD monitors on the market use USB as a video input interface, making it possible to output and display a PC screen through a USB connection between the PC and the LCD display. These, too, are ideal for laptops and netbooks, since they allow users to use laptops connected to large-screen LCD monitors at their office desks or at home, then use the laptops for mobile use when out and about simply by unplugging a single USB cable.
Monitor ports have changed over the years. Not only can they carry increasingly complex data, but they can also charge and power the devices that they connect. Like any technology, monitor ports are undergoing a continuing evolution to improve image quality and power efficiency.

When it comes to monitor ports, there are many options available on the market today. Ports that were once the industry standard for connection are becoming obsolete, replaced by faster, more efficient, and more compact versions.
The USB-C is known as the all-in-one connector. It is a one-cable solution with the ability to transmit power, audio, and video across a single cable from one mighty port.
Simply put, it can power smaller devices like your smartphone, and larger devices, such as computers and laptops, which generally require 60 watts of power to charge fully. Plus, it’s bi-directional, capable of transmitting as well as receiving power.
And with this connector, enjoy its reversible orientation. This feature promotes ease of use and eliminates the need for multiple ports and cables. It also lets you easily connect the cable into the connector correctly the first time – no more struggling to find the correct orientation.
With its universality, speed, power, and versatility, the USB-C port is a popular choice for computer monitors, opening a wealth of possibilities to increase productivity and efficiency at the office. The ViewSonic VG2456 Series monitors, for example, utilize USB-C to offer an all-in-one cable solution:
Alternatively, the VP2785-4K is a powerhouse monitor featuring a stunning 3840 x 2160 resolution (4K) with multiple ports offering connections to USB 3.1 type C, as well as DisplayPort and HDMI. These advanced features and high color standards make it a perfect choice for various design professions, including photography, graphic design, video editing, and print.
With the addition of the Thunderbolt hardware interface, the already high-performing USB-C offers even greater speed. It is now the most versatile and powerful connector in today’s market. Compatible with any dock, display, or data device, Thunderbolt brings USB-C speeds up to 40Gb per second – 8x faster than the ports available on most computers today. Besides, it significantly increases USB-C power and image quality, allowing it to hold 8x as much data, and boosts image quality to 4x the bandwidth.
DisplayPort was developed to replace VGA, DVI, and FPD-link. With the use of adapters, it also easily connects to other interfaces such as VGA, DVI, and HDMI.
Supporting both audio and video signal transmissions, you can quickly get more done than ever before using one powerful monitor. Flexible connectivity options make it possible.
With the right monitor and monitor port, you can serve multiple needs to maximize your productivity at the workplace. For example, the ViewSonic VG2755-2K comes equipped with HDMI ports and a VGA input. It offers versatile connectivity options to PC’s laptops and other multimedia devices, making it an excellent choice for the office.
Capable of carrying signals with the use of inexpensive cables, and very user-friendly, HDMI has been a popular choice among interface connectors. It is now the standard for plugging a computer into a TV monitor.
HDMI ports have their drawbacks, however, which makes other options a better choice at times. The main limitation of the HDMI cable is the distance in which its transmissions can travel (about 15 meters or 50 feet is considered the upper limit). Likewise, they are quite bulky. As technology has advanced, smaller versions of HDMI cables, usually called Micro or Mini, were invented to accommodate our mobile devices and tablets, but the standard size is pretty big as far as modern cables go.
Capable of carrying signals at resolutions as high as 2560 x 1600, it helped maximize the digital quality of flatscreen LCD monitors and modern video graphics cards. It has been a top choice for HDTVs and other high-end video displays for TV, movies, and DVDs, while also supporting both computer monitors and projectors. In recent years, DVI has become the standard digital interface for the computer market.
VGA ports are composed of 15 pins, with three rows of five pins, it can transmit RGBHV video signals: Red, Green, Blue, Horizontal Sync, and Vertical Sync. That said, VGA is limited to carrying analog signals, so it produces lower quality resolutions on screens. In recent years, it has been used far less, being replaced by faster DVI and HDMI ports, which provide higher quality resolutions and displays.
USB-C is a truly powerful port bringing a host of its specific benefits, while also offering compatibility with other ports. Still, DisplayPort, Mini DisplayPort, DVI, HDMI, or VGA can be a better choice depending on what you are trying to achieve with your device.
Thanks to monitor ports and the wealth of advances they offer, we can do more with our devices than ever before. The possibilities could be truly endless, even sooner than we thought.

Transition-Minimized Differential Signaling (TMDS) – When digital data is transmitted, especially over long distances, it is susceptible to noise and signal loss. TMDS is a way of encoding an HDMI signal to protect it from interference as it travels from source to receiver. It works like this:
Consumer Electronic Control (CEC) – This feature allows a user to control up to 15 connected HDMI devices using one remote controller. Most TVs and streaming devices support CEC but it may be turned off by default. Manufacturers sometimes refer to CEC using their own branded term (e.g. Anynet+, Viera Link) so it may not be apparent that your device supports it.
High-Bandwidth Digital Content Protection (HDCP) – this authentication protocol allows a sending and receiving device to verify each other"s credentials (stored on each device"s Extended Display Identification Data (EDID) chip) and, if every checks out, create a shared key that is used to encode and decode the data passing between them. This process, known as a handshake, happens almost instantaneously at the beginning of a session and ensures that an unauthorized device cannot intercept the data as it travels between two devices. In the United States, HDCP support is mandated by the Federal Communications Commission (FCC).
Display Data Channel (DDC) – The HDMI interface includes support for VESA DDC, a set of protocols that allow a source (a computer"s graphics card, for example) to ask a monitor what audio and video formats it can handle, and adjust settings on the monitor, such as brightness and contrast. The information exchanged by a source device and a display is called Extended Display Information Data (EDID) and is transmitted through the Display Data Channel.
Each pixel in a video image includes information on brightness (luma) and color (chroma). Since human eyes are more sensitive to differences in brightness than color, chroma subsampling reduces the amount of data transmitted by allowing pixels to share color data with adjacent pixels.
Chroma Subsampling is represented as three digits. The first number is the number of pixels in each row of the sample. The second number indicates the number of pixels in the TOP row that have color information. The third number indicates the number of pixels in the BOTTOM row that have color information.
The initial HDMI specification provided support for 24-bit Color Depth (8-bits per color x 3 colors RGB). HDMI 1.3 introduced Deep Color, which added support for 30-bit, 36-bit and 48-bit color depths. It"s worth keeping in mind that the human eye can only distinguish around 10 million different color, so 24-bit color is adequate for most situations.
Audio Return Channel (ARC) – Most TVs connect to a sound bar or AV receiver using an optical cable. ARC enables a TV to send audio back to a sound bar or AV receiver through the same cable that delivered the HDMI signal to the TV. In other words, video and audio to the TV and audio back to the sound bar (the "return" part). The benefits of ARC include fewer cables, use of the TV remote to control sound, and the ability to transmit higher resolution audio, such as Dolby TrueHD or DTS HD Master Audio, to your sound bar or receiver. [Version 1.4]
HDMI Ethernet Channel (HEC) –First introduced in the HDMI 1.4b specification, HEC allows Ethernet-enabled devices to share an Internet connection. It combines the features of an Ethernet cable into the HDMI cable, thereby avoiding the need for a separate Ethernet cable. Xbox 360 and Roku are two examples of devices that can take advantage of HEC to connect to the Internet. [Version 1.4]
Enhanced Audio Return Channel (eARC) was introduced in HDMI 2.1 and provides support for higher-quality audio bandwidth and speed. eARC requires a High Speed HDMI cable with Ethernet or an Ultra High Speed HDMI cable. eARC is not backwards compatible with ARC but some products may support both eARC and ARC. [Version 2.1]
Display Stream Compression (DSC) – HDMI is uncompressed audio and video. The higher the resolution, color depth and frame rate, the more bits need to be transmitted until the maximum bandwidth is reached. Then, the only way to transmit more bits is to add more lanes to the cable or compress the signal.
HDMI 2.1 introduced support for Display Stream Compression (DSC) 1.2a, a visually lossless compression for ultra-high definition (UHD) video. Using DSC, an HDMI 2.1 cable can support a maximum compressed bandwidth of 128 Gbps (sufficient for 10K, although it will be some time before there are commercially available devices that need that much bandwidth).
No it does not, I bought it to take an HDMI output from a laptop and provide a display port plug for a monitor that didn"t have an HDMI port. Sadly it does not work for this. I verified that when plugged into a display port source it does properly convert the signal to HDMI so I could take the 1 laptop that had a DP port and plug it into my TV, but not the laptop that had an HDMI and plug it into my DP monitor. I haven"t yet found a cable that does what I need but will update when I find one.
The display in modern monitors is typically an LCD with LED backlight, having by the 2010s replaced CCFL backlit LCDs. Before the mid-2000s,CRT. Monitors are connected to the computer via DisplayPort, HDMI, USB-C, DVI, VGA, or other proprietary connectors and signals.
Originally, computer monitors were used for data processing while television sets were used for video. From the 1980s onward, computers (and their monitors) have been used for both data processing and video, while televisions have implemented some computer functionality. In the 2000s, the typical display aspect ratio of both televisions and computer monitors has changed from 4:3 to 16:9.
Modern computer monitors are mostly interchangeable with television sets and vice versa. As most computer monitors do not include integrated speakers, TV tuners, nor remote controls, external components such as a DTA box may be needed to use a computer monitor as a TV set.
Early electronic computer front panels were fitted with an array of light bulbs where the state of each particular bulb would indicate the on/off state of a particular register bit inside the computer. This allowed the engineers operating the computer to monitor the internal state of the machine, so this panel of lights came to be known as the "monitor". As early monitors were only capable of displaying a very limited amount of information and were very transient, they were rarely considered for program output. Instead, a line printer was the primary output device, while the monitor was limited to keeping track of the program"s operation.
Multiple technologies have been used for computer monitors. Until the 21st century most used cathode-ray tubes but they have largely been superseded by LCD monitors.
The first computer monitors used cathode-ray tubes (CRTs). Prior to the advent of home computers in the late 1970s, it was common for a video display terminal (VDT) using a CRT to be physically integrated with a keyboard and other components of the workstation in a single large chassis, typically limiting them to emulation of a paper teletypewriter, thus the early epithet of "glass TTY". The display was monochromatic and far less sharp and detailed than on a modern monitor, necessitating the use of relatively large text and severely limiting the amount of information that could be displayed at one time. High-resolution CRT displays were developed for specialized military, industrial and scientific applications but they were far too costly for general use; wider commercial use became possible after the release of a slow, but affordable Tektronix 4010 terminal in 1972.
Some of the earliest home computers (such as the TRS-80 and Commodore PET) were limited to monochrome CRT displays, but color display capability was already a possible feature for a few MOS 6500 series-based machines (such as introduced in 1977 Apple II computer or Atari 2600 console), and the color output was a speciality of the more graphically sophisticated Atari 800 computer, introduced in 1979. Either computer could be connected to the antenna terminals of an ordinary color TV set or used with a purpose-made CRT color monitor for optimum resolution and color quality. Lagging several years behind, in 1981 IBM introduced the Color Graphics Adapter, which could display four colors with a resolution of 320 × 200 pixels, or it could produce 640 × 200 pixels with two colors. In 1984 IBM introduced the Enhanced Graphics Adapter which was capable of producing 16 colors and had a resolution of 640 × 350.
By the end of the 1980s color progressive scan CRT monitors were widely available and increasingly affordable, while the sharpest prosumer monitors could clearly display high-definition video, against the backdrop of efforts at HDTV standardization from the 1970s to the 1980s failing continuously, leaving consumer SDTVs to stagnate increasingly far behind the capabilities of computer CRT monitors well into the 2000s. During the following decade, maximum display resolutions gradually increased and prices continued to fall as CRT technology remained dominant in the PC monitor market into the new millennium, partly because it remained cheaper to produce.
There are multiple technologies that have been used to implement liquid-crystal displays (LCD). Throughout the 1990s, the primary use of LCD technology as computer monitors was in laptops where the lower power consumption, lighter weight, and smaller physical size of LCDs justified the higher price versus a CRT. Commonly, the same laptop would be offered with an assortment of display options at increasing price points: (active or passive) monochrome, passive color, or active matrix color (TFT). As volume and manufacturing capability have improved, the monochrome and passive color technologies were dropped from most product lines.
The first standalone LCDs appeared in the mid-1990s selling for high prices. As prices declined they became more popular, and by 1997 were competing with CRT monitors. Among the first desktop LCD computer monitors was the Eizo FlexScan L66 in the mid-1990s, the SGI 1600SW, Apple Studio Display and the ViewSonic VP140vision science remain dependent on CRTs, the best LCD monitors having achieved moderate temporal accuracy, and so can be used only if their poor spatial accuracy is unimportant.
High dynamic range (HDR)television series, motion pictures and video games transitioning to widescreen, which makes squarer monitors unsuited to display them correctly.
Organic light-emitting diode (OLED) monitors provide most of the benefits of both LCD and CRT monitors with few of their drawbacks, though much like plasma panels or very early CRTs they suffer from burn-in, and remain very expensive.
