What is HDMI (High Definition Multimedia Interface)?

Cables, like the , which boast a data rate of 48Gbps, enough for 8K at 60Hz or 4K at 120Hz. I have not compared switch latency to Display Port, so would be curious if anyone here has impressions. We say 'minimum' because there are a bunch of other factors as well. It can seem like just one of many connections on or receivers. There are two important considerations you need to be aware of, though. When considering longer cable runs, cable quality becomes much more important. The Ethernet channel can carry data between two connected devices, allowing them to share a wired Internet connection. The result is a more accurate, vibrant, and … well, dynamic picture. It varies, sometimes by quite a lot depending on the complexity of the scene. Do you need this kind of cable? Fewer cables, less mess, better sound! If an unauthorized device tries to intercept the data, the source device stops transmitting. Check out our for all kinds of devices and installations. The latest and are packed with features, but one aspect that often gets overlooked is the inclusion of DisplayPort vs. The standard in the past has been 24-bit color, or 8 bits each for the red, green and blue color components. Common Resolution Bandwidth Requirements Resolution Color Depth Refresh Rate Hz Required Data Bandwidth 1920 x 1080 8-bit 60 3. The source device encodes its information using the key it generated it. But is there a clear winner between the two? Here is the layout of the pins. Higher framerates mean smoother, better-looking games. This may reset the authentication cycle and restore your connection. It works fine for gaming at , or resolution if you have a dual-link connection. Data transfer speeds are slower, reliability can be questionable, and the number of users on the network can have a major impact on performance. Multiply the color depth by the number of pixels and the screen refresh rate and you get the minimum required bandwidth. That's because display blanking intervals need to be factored in. And if they did, you'd be using an analog that's prone to interference. Now, more than ever before, individuals have to the ability to use their computer hardware in tandem with their televisions, expanding the viewable display area for their computer in the process. In theory, this is possible, but it is highly unlikely. For example, basic 24 bpp at 8K and 60 Hz needs 49. I have lost patience for technology regression as I have aged. I've had monitors that take as long as 10 seconds to switch to a signal or even turn on in the first place , and I've had others that switch in a second or less. What are the differences between the two ports and is using one for connecting to your system definitively better? In other words, it creates a shared secret. Its resolution, or the number of dots that make up the picture on the screen, was about 704 x 480 pixels. The only hangup with Dolby Vision is that it is a proprietary technology and not every electronics manufacturer wants to pay licensing fees to use it. So dual-link may be used for larger monitors. Quick Media Switching You know that blank, black screen you get sometimes when you switch sources or from games to streaming apps? I include a link below that is informative on that topic--it's not mine but I saved the link to remind me. I appreciated the fact that the article mentioned the loss of color fidelity the 144Hz compromise forces, although most people seem to ignore that difference. If you encounter any difficulties when plugging the cable into the ports, stop completely and check for obstructions. An would already be connected to the device in order to transfer video and audio signals, and now it could also be used for online connectivity — no muss, no fuss, no WiFi, and no additional cables to run. Using standard Cat5 or Cat6 networking cable, this system is far easier to wire through walls, and much easier to repair if the cable becomes damaged. So, probably just a poor implementation of that process, running on some dog-slow embedded processor. Earlier versions of each standard can use even less data for audio. Digital Compatibility Can convert to other standards like. That only requires 14;08 Gbps for 24-bit color or 17. As has always been the case in the tech world, sometimes watching the change happen is just as fun as experiencing the change itself. Another possibility is connecting a Blu-ray player to a high-definition monitor or television. The dual link form provides twice as much and delivers the data more rapidly than the single link kind. We also like the robust DisplayPort but not mini-DisplayPort connector, which has hooks that latch into place to keep cables secure. Generally speaking, display signals use either 24 bits per pixel bpp or 30 bpp, with the opting for 30 bpp. The receiving device decodes it using the same information. In other words, the cost to end users is easily absorbed in most cases — unless some bean counter comes down with a case of extreme penny pinching. So what does that mean for you and your entertainment system? Officially, the maximum length of a DisplayPort cable is up to 3m 9. That may not be important for a display sitting on your desk, but it can definitely matter for home theater use. In this case, pay careful attention to which specific port you use, as you will need to select this as your designated input at a later stage. Instead of having to run two Ethernet cables, one to an Internet-ready television and a second to the game console, the same connection could be shared on the cable already running between the two components. However, the connection between your display and graphics card will end up using the best option supported by both the sending and receiving ends of the connection. If both keys check out, the sending device moves on to the next step. If you're looking to or you can find recommendations on our page , you'll want to consider the capabilities of both sides of the connection — the video output of your graphics card and the video input on your display — before making any purchases. Gamers will notice much less lag, especially those who like fast-action first-person shooters. Read customer and pro reviews carefully before you buy a long cable and make sure the manufacturer has a good warranty. Both standards are capable of delivering a good gaming experience, but if you want a great gaming experience, right now DisplayPort 1. A 1920 x 1080 monitor at a 60 Hz refresh rate, for example, uses 2,000 pixels per horizontal line and 1,111 lines once all the timing stuff is added. Here is the layout of the pins The analog pins are the four that surround the flat blade as shown in the picture. Because the standard has evolved over the years, not all DisplayPort cables will work properly at the latest speeds. It's a set of rules for allowing high-definition electronic devices to communicate. Ideally, this whole process, known as a handshake, takes place almost instantaneously. And running supplemental Ethernet cables to all of your devices can be a logistical nightmare. Here's what you need to know about DisplayPort vs. Despite these prodigious features, these cables still cost less than a movie ticket and are guaranteed for life. Anything lower than that will also work without trouble on either connection type. The picture was roughly square -- its aspect ratio was 4:3. The encoding step helps protect signal quality by reducing the number of chances for the signal to degrade. They use information in the form of ones and zeros. Jeff Park, director of technology at , informed us that while there are premium chips out there which can be firmware upgraded, they are extremely expensive and rarely used by manufacturers. It uses this information to compensate for any loss of signal along the way. It measures the differential, or the difference between the signal and its inverse. For Nvidia gamers, your best option right now is a DisplayPort 1. Look at the following table and compare it with the first table; if the required data bandwidth is less than the max data rate that a standard supports, then the resolution can be used. The other carries an inverse copy of the signal. Bandwidth isn't the only factor, but in general, the standard with a higher maximum bandwidth is 'better. But in other cases, there's an easy fix -- unplug your components and power cycle your system. Another big issue for me is input switching latency when I flip between sources, which is something missing from product specifications and reviews unless I've somehow missed seeing it. As you can see, the new standard opens up a wealth of new possibilities. The cable itself is composed of twisted pairs of cables that are also shielded. Image credit: Future DisplayPort vs. In many ways, you are planning for the future as much as for the present when buying an. Display timings are relatively complex calculations. Some of that will depend on the hardware you already own or intend to purchase. Both are digital standards, meaning all the data about the pixels on your screen is represented as 0s and 1s as it zips across your cable, and it's up to the display to convert that digital information into an image on your screen. But just as importantly from a gaming perspective, it allows for variable framerates. The current standard can carry 1080p high-definition signals, and it supports eight channels of uncompressed audio, enough for a 7. I'm not sure if it's just poor firmware, or a cheap scaler, or something else. As the technology improves, you can swap out the transmitter and receiver for newer devices, without rewiring. Think of each transition as a sharp drop-off -- as the signal travels, this drop-off can begin to wear away, degrading the signal. There is a digital to analog conversion applied here, but this still gives higher-quality results than a standard cable. This information travels through cables as distinct electrical pulses. My experience is that it's more the monitor than the input. The changes are exciting, but it will be years more until specs like and 4K at 120Hz are anywhere close to mainstream. This not only makes it easier to run the cable, but it also offers additional protection. CerianK said:Another big issue for me is input switching latency when I flip between sources, which is something missing from product specifications and reviews unless I've somehow missed seeing it. It generates a new key and shares it with the receiving device. Thunderbolt 2 supports DisplayPort 1. With a maximum data rate of 25. Assuming your graphics card also supports both connections and it probably does if it's a card made in the past five years , in many instances the choice of connection won't really matter. The picture was interlaced -- each piece of the moving image was really half a picture, but the pictures changed quickly enough that the human brain didn't really notice. In some people's minds, the lack of conversion means that the signal is in a pure, undamaged state when it reaches the set. When that happens, the display can automatically turn off any picture processing that could introduce latency or lag. DisplayPort isn't fully royalty or licensing fee free, however. The preferred solution, especially over longer distances, is an. Unless you're planning on gaming on the big screen in the living room, you're better off with DisplayPort right now. It also makes sure that the key hasn't changed and that the system is still secure every few minutes. Our will tell you how the various graphics cards rank in terms of performance, but it doesn't dig into the connectivity options, which is something we'll cover here. That's not a very common scenario, but DisplayPort does make it possible. However, it certainly has its drawbacks, particularly when compared with a wired network. Here are the ways these forward-looking cables can work, though. These issues can make relying on WiFi connectivity a major issue if your high-definition television, video gaming console or Blu-Ray player need to be hooked up to the Internet. It is much less commonly-used for computer applications. Let's Talk More About Bandwidth Image credit: Shutterstock To understand the above chart in context, we need to go deeper. When Ampere arrives later this year, it will probably support DisplayPort 2. These can suffer from signal degradation, and you might find that long cables do not maintain a reliable connection between your devices. As such, you might find that locking down the configuration range of the source can speed things up, a bit. In other words, Dolby Vision makes changes to the settings of an image as the image itself changes. A fast and reliable Internet connection is essential for live gaming against other online players, and is even necessary for downloading updates or new software.。 。 。 。 。 。 。
