DisplayPort and HDMI are two of the most popular connector types you’ll find on modern TVs and monitors, serving the purpose of transmitting video and audio from a source device to a compatible display. However, when comparing specific generations like DisplayPort 1.4 and HDMI 2.1, there are distinct advantages and reasons for choosing one over the other.

In today’s fast-paced gaming world, selecting the right display connection is crucial for an enhanced gaming experience. In this article, we’ll delve into the features of DisplayPort 1.4 and HDMI 2.1, examining their differences and determining which one reigns supreme for gaming.

What Is DisplayPort 1.4?

DisplayPort 1.4, one of the latest iterations of the DisplayPort protocol, has been a go-to choice for PC gamers seeking high frame rate 4K gaming experiences. Despite the arrival of HDMI 2.1, DisplayPort 1.4 remains the primary connector type used in the realm of PC gaming. However, outside of desktop PCs, DisplayPort 1.4 is less commonly found, as laptops, tablets, and game consoles often rely on HDMI connections for video outputs.

Characterized by its rectangular shape with a notched corner, DisplayPort 1.4 utilizes 20 pins to achieve a maximum bandwidth of 32.40 Gbps or a maximum data rate of 25.92 Gbps. It supports both 8-bit and 10-bit color and can handle Display Stream Compression (DSC) 1.2a.

With its High Bit Rate (HBR), High Bit Rate 2 (HBR2), and High Bit Rate 3 (HBR3) transmission modes, DisplayPort 1.4 offers ample bandwidth capabilities, enabling it to deliver 4K resolution at up to 120Hz, 5K resolution at up to 60Hz, and 8K resolution at up to 30Hz.

What Is HDMI 2.1?

HDMI 2.1 takes the achievements of its predecessors even further, offering substantial enhancements and positioning itself as the dominant connector type for home entertainment setups. One of its significant advancements is the remarkable increase in maximum data rate.

With a bandwidth of 48 Gbps, HDMI 2.1 surpasses the mere 18 Gbps of HDMI 2.0. This boost is made possible through the use of higher-quality cable materials and a new encoding scheme known as 16b/18b, which significantly improves efficiency and supports the higher data rate.

The improved bandwidth of HDMI 2.1 translates into impressive resolution and refresh rate capabilities. It natively supports 4K gaming at 120Hz on consoles and up to 4K at 144Hz on gaming PCs with powerful graphics cards. Additionally, it can handle 5K resolution at up to 60Hz and 8K resolution at up to 30Hz. By utilizing Display Stream Compression (DSC), HDMI 2.1 even achieves 8K resolution at up to 120Hz with HDR.

Beyond the enhanced resolution and refresh rate support, HDMI 2.1 introduces several new features to the standard. Dynamic HDR allows for scene-by-scene HDR settings changes, resulting in improved picture quality. The enhanced variable refresh rate minimizes stuttering and screen tearing, providing a smoother gaming experience.

Transmission rates

Both DisplayPort 1.4 and HDMI 2.1 provide high data transmission rates, but HDMI 2.1 takes the lead in this category. It offers a maximum data rate of 48 Gbps, which is significantly higher than the 32.4 Gbps offered by DisplayPort 1.4. This increased bandwidth allows HDMI 2.1 to handle higher resolutions and refresh rates more efficiently.

Maximum supported resolution

HDMI 1.4 supported 4K resolution at 30 FPS, while HDMI 2.0 raised the bar to 4K at 60 Hz or 8K at 30 Hz. The latest HDMI 2.1 standard takes it even further, enabling 4K resolution at 120 Hz and 8K resolution at 60 Hz. Impressively, HDMI 2.1 can even support resolutions as high as 10K.

Similarly, DisplayPort 1.4 also supports 4K resolution at 120 Hz and 8K resolution at 60 Hz.

However, it’s worth noting that these maximum resolutions may exceed current requirements for many users. While 1080p remains the most common resolution today, 4K is still gradually making its way into households. Therefore, the capabilities provided by HDMI 2.1 and DisplayPort 1.4 may seem excessive for the majority of users at present.

HDR Support

HDR (High Dynamic Range) support enhances the visual experience by providing superior contrast ratios on compatible displays. HDR displays offer more vibrant and impactful images compared to standard displays.

HDMI 2.1 introduced dynamic HDR support, allowing for dynamic adjustments in HDR settings scene by scene. On the other hand, DisplayPort 1.4 supports static HDR, which provides a fixed HDR setting throughout the content.

Number of Displays supported

When considering the number of displays your PC can support, it’s important to understand the display interfaces supported by your GPU and monitor.

HDMI interface typically supports a single display, whereas DisplayPort offers the advantage of supporting up to 4 displays. If you wish to connect additional displays, you would need to use separate HDMI cables for each one.

For most users, the ability to connect 2 or 3 displays is more than sufficient. Whether you opt for a display with DisplayPort or HDMI, the key factor is compatibility between your GPU and monitors, as both need to support a common communication standard for multiple displays to be connected.

Audio

Both DisplayPort 1.4 and HDMI 2.1 support high-quality audio, including formats like Dolby Atmos and DTS:X. However, HDMI 2.1 provides additional audio features, such as eARC (enhanced Audio Return Channel), which enables high-quality audio from your display to be sent back to your sound system with minimal loss.

Applications

When it comes to applications, the HDMI port enjoys broader adoption compared to the DisplayPort. HDMI ports are found on millions of readily available monitors and televisions in the market. In contrast, the use of DisplayPort is mainly prevalent in gaming and workstation monitors.

In terms of advantages, there are no significant differentiators between the two interfaces, especially considering the continuous evolution of the standards. However, in the case of HDMI 2.1 versus DisplayPort 1.4, HDMI 2.1 holds a slight edge. Nevertheless, for the average consumer, the difference between them is not a major concern.

DisplayPort 1.4 vs. HDMI 2.1: Optimizing Your Gaming Experience

For Xbox Series X/S and PlayStation 5 gaming, an HDMI 2.1 cable is the optimal choice. These current-gen consoles exclusively feature HDMI 2.1 as their video-out connector. While HDMI 2.0 and older cables can still be used, the best experience is achieved with HDMI 2.1, enabling full resolution and refresh rate support. This allows for gameplay at 1440p or even native 4K resolution at up to 120Hz.

The Nintendo Switch also supports HDMI but is limited to HDMI 2.0. Therefore, the benefits of using an HDMI 2.1 cable won’t be significant. However, Ultra High-Speed rated HDMI 2.1 cables are built to a higher standard than older ones, ensuring superior signal quality when playing the Switch on a connected TV or display.

For gaming desktop PCs, DisplayPort remains the preferred choice. While HDMI 2.1 can be used if you have a compatible monitor or TV, it should be noted that using it for multiple monitors will reduce the available bandwidth for each display.

In all other scenarios, DisplayPort 1.4 is still the superior option. It provides ample bandwidth for 4K at up to 120Hz or up to 240Hz for 1440p displays, offering headroom for high frame rates at lower detail settings. DisplayPort is more widely available on PCs, providing multiple ports for easy setup of multi-monitor display systems, with a single DisplayPort connection for each monitor.

When gaming on laptops, tablets, or smart devices, the choice of connector will depend on the specific device’s outputs. While HDMI 2.1 outputs are rare, devices with HDMI and DisplayPort will typically favor DisplayPort. Alternatively, a USB-C connection with DisplayPort Alt Mode support would be a suitable option.

For Steam Deck gaming, the Steam Deck Dock allows you to connect to a gaming TV or monitor. However, the dock only offers HDMI 2.0 and DisplayPort options. In this case, if possible, using DisplayPort 1.4 would be preferable over HDMI 2.0. Additionally, the Steam Deck Dock supports multi-stream transport, allowing for simultaneous use of both connectors for multi-screen gaming.

Conclusion

In the battle of DisplayPort 1.4 vs. HDMI 2.1, the choice ultimately depends on your specific needs and gaming setup. HDMI 2.1 excels in terms of bandwidth, maximum resolution support, and advanced audio features, making it ideal for those who crave the best visuals and audio fidelity.

On the other hand, DisplayPort 1.4’s MST support and prevalence in the PC gaming industry make it a compelling choice for users who require multi-monitor setups or prioritize precise color reproduction.

Ultimately, both DisplayPort 1.4 and HDMI 2.1 offer impressive capabilities and are widely supported in the market. It’s important to consider the requirements of your gaming setup and the specific devices you’ll be connecting to make an informed decision.

Everything You Should Know Before Buying a KVM Switch

KVM switches are widely used in server rooms and data centers today. What are KVM switches and why are they so popular? How can 20 servers be controlled simultaneously with “one-click” if there are 20 servers in the room? In actual applications, KVM switches can accomplish that.

Do you already understand KVM, or are you still unsure of how to connect to a KVM switch? Here, some of the most frequently asked questions about KVM switches will be covered.

What Is a KVM Switch?

KVM, which stands for keyboard, video, and mouse. Using a single keyboard, video display monitor, and mouse, users can control several computers using a KVM switch, a piece of hardware.

Because it connects other devices utilizing copper cables like Cat5, Cat5e, or Cat6, it is sometimes known as a “CATx KVM switch.” The administrator can quickly switch control from one server to the next by pressing a button on the KVM switch.

What Kinds of KVM Switches Are Typically Used?

KVM switches are available in a variety of sizes and configurations, just like the other devices used in homes or data centers. For applications with space restrictions, there are rack-mount KVM switches.

HDMI over Fiber Extender for HDMI Extension

If you need to connect a device farther away, like in another room or across the house, a regular HDMI cable may not be sufficient for some setups. Since standard HDMI cables have a limited reach, with the max cable length of 49ft (15 m), which means you’ll need to find a way to extend the connection.

Fortunately, there are several ways to extend HDMI connections, among which HDMI over fiber extenders are a perfect alternative if you need to connect a device from a father distance.

In this article, I will focus on HDMI over fiber extenders and also explore other useful ways to extend HDMI. After reading this article, you won’t be limited by the distance of where you want to connect your devices to a display.

What is an HDMI Over Fiber Extender?

HDMI over fiber extenders leverage standard single mode or multimode fiber to transmit audio, video and associated signals (such as control and network depending on the extender model). Basically, they are like twisted pair extenders that rely on optical fiber instead of copper.

HDMI over fiber extenders eliminate the typically limited range of standard HDMI cables. When connected, the picture quality will look the same as if you had your device (PC, game console, or similar) connected close by your display.

Advantages of HDMI over Fiber Extenders

Extremely long transmission distances — signals can be extended up to 6 miles or more depending on the model.

Integration of IR, RS232 and Ethernet signal extension over the same fiber.

Compatibility with standard single mode or multimode fiber terminated with LC connectors — basically the same cable used for networking.

Complete immunity to interference, static electricity, surges and other environmental factors that affect twisted pair extenders.

Extremely high signal bandwidth support, including uncompressed HDMI transmission.

Uses of HDMI Over Fiber Extenders

Since fiber cables are made of glass, which eliminates extra electrical interference, such as electricity from lightning, power surges, and static electricity, HDMI over fiber is best for in-wall installations or for extending the connection far further than the other solutions can go.

You may run the cable through the walls or underground, for instance, if you wanted to extend from a building’s top or to another house. If you like, you may still use HDMI over fiber for shorter extensions, despite they’re designed for longer extensions.

While there are other ways to extend HDMI connections, the best choice for long distances is still HDMI over fiber.

Other Ways to Extend HDMI

There are other options available to extend an HDMI connection, such as an HDMI repeater, fiber optic HDMI cable, HDMI over IP extender, HDMI over HDBaseT extender, or an HDMI balun. Each solution has its limits, so it’s best to pick the best type for your situation.

Below, I give more details about each solution:

HDMI Repeater. An HDMI repeater extends the connection by connecting two HDMI cables and amplifies the signals for better transmission. It is best for shorter ranges of 60 to 100ft for 4K displays. Not recommended to go through walls.

Fiber Optic HDMI Cable. Designed to extend farther distances up to 164ft (50m) for 4K@60 Hz, fiber optic HDMI cables are like standard HDMI cables but made with optical fiber inside the cable. They aren’t meant to be used with an extender, repeater, or switch and should be used alone.

HDMI over IP Extender. It uses an existing ethernet infrastructure to distribute HD video signals from one source to an unlimited number of screens. Video signals can be switched from any source to any screen, overcoming distance limitations of traditional CATx video extenders.

HDMI over HDBaseT Extender. A global standard that transmits ultra-high-definition video and audio, Ethernet, controls, USB, and up to 100W of power over a single long-distance cable. Because HDBaseT eliminates cable clutter without affecting performance or high quality, it is widely used in many industries.

HDMI Balun over Cat cable. Baluns allow you to send ultra high resolution signals, such as DVI and HDMI, longer distances. Twisted pair cable is smaller and easier to pull/hide than traditional cable. Baluns help eliminate ground loops and RF interference.

HDMI eARC- 4 Things You Need to Know

If you have tried plugging an HDMI cable in your new TV, soundbar, or AV receiver (AVR) recently, you may have come across a relatively new acronym called eARC. Here’s what it means and why it’s important.

What’s HDMI eARC?

eARC or Enhanced Audio Return Channel is an upgraded version of ARC (Audio Return Channel). It was introduced in 2017 as a part of the HDMI 2.1 specification. Similar to ARC, eARC lets your TV send audio generated by built-in streaming apps, cable, satellite, and other source devices (for example, a gaming console or a Blu-Ray player) to your soundbar or AVR using a single HDMI cable. However, eARC supports far greater bandwidth and speed than ARC, thus allowing the transfer of high-quality, uncompressed audio, which isn’t possible with ARC.

How does HDMI eARC Work?

To put it briefly, HDMI eARC allows a TV to send audio back through the HDMI cable to its source device. Then why would anyone want to do that?

Does your TV have good speakers? No? If so, eARC is the best solution. You will naturally want to hear great audio to enable a better immersive experience, whether you’re playing games with your pals or watching shows on Netflix, Disney+, or other streaming services. Additionally, clear audio creates a cozy atmosphere for movie night.

Before technologies like HDMI eARC were available, you had to run a second cable from your TV back to your receiver. Having more than one cable already looks messy, but you also have to take a few extra steps every time you switch between your speaker and TV as the sound source.

With less setup time, HDMI eARC gives you the same or even better quality.

What are the Benefits of Using HDMI eARC?

HDMI eARC offers much more than just crystal-clear audio. There are other significant benefits of using an HDMI eARC cord. So check these out:

High-resolution images

You will be able to transmit uncompressed digital audio signals and images because of the high bandwidth of HDMI eARC. Higher definition videos and other content are produced thanks to this technology. HDMI eARC will be your perfect match if your TV supports 4K, 8K, or higher.

Automated lip-sync feature

Are you sick of manually adjusting your TV or AV’s delay settings to make the sound and picture sync? What works best is HDMI eARC. HDMI eARC has an automatic lip-sync feature, which means you don’t need to make any adjustments yourself. Simply connect everything, select the proper HDMI settings, and enjoy the show.

No HDMI CEC required

The requirement for HDMI CEC is among the biggest distinctions between HDMI ARC and HDMI eARC. Unlike ARC, eARC does not require HDMI-CEC to function. The device detection system for HDMI eARC is already built in. Once everything is connected and the HDMI settings are correct, you can kick back and watch whatever program you choose.

Is HDMI eARC Backwards Compatible with HDMI ARC?

This depends on what you mean by backwards compatible. HDMI eARC has ARC fallback, meaning that if you hook up one device with HDMI eARC with another device that doesn’t support it, the devices will fallback to broadcasting an HDMI ARC signal instead. That means you will still be able to get some audio, but you won’t experience the high bitrate audio that eARC intends to provide.

How to fix that? You can try to upgrade your soundbar or AV receiver to support HDMI eARC. But this will heavily depend on their manufacturer and the hardware used to make them.

Conclusion

The advantages of HDMI eARC far exceed the inconvenience of having to look for TVs, audiovisual devices, or soundbars that support it as it is a relatively new technology.

Moreover, HDMI cords aren’t regarded “ancient” or “outdated” for roughly ten years (or more). That’s a long time using devices that are incompatible with eARC.

Businesses have begun to make efforts to satisfy the needs of the HDMI eARC community. Before you know it, eARC-compatible devices will be available in all local and online electronics stores.

Wireless HDMI Extender: Everything You Need to Know Before Buying

If you’ve got a projector, or if you just want to get clever with hiding away game consoles or other video sources, wireless HDMI extenders might be something you’re considering.

A wireless HDMI extender enables you to transmit audio and video content from various HDMI-enabled devices, such as gaming consoles, computers, and cable boxes. It allows you to remove unsightly HDMI cables from your setup, and even frees up options like storing the video source in an entirely separate room.

A wireless HDMI extender is very simple to use, but there are certain facts you should be aware of before buying it.

How Does A Wireless HDMI Extender Work?

A wireless HDMI extender comes with two parts: the HDMI video transmitter and receiver. A transmitter wirelessly sends a data signal stream. A receiver receives the data and streams it to your TV.

Transmitter – The transmitter connects to an audio or video source device such as a set-top box, gaming console, or Blu-ray player. Then it sends a wireless signal from the source device to the receiver.

Receiver – The receiver connects to your TV. It then wirelessly receives the audio/video data stream from the transmitter up to a 150-feet away and displays it on the TV.

Will it Interfere with Your Wi-Fi Network?

With your Xbox or PlayStation, wireless router, and wireless HDMI transmitter all stored in the same spot, things can get a little tangled. Since game console has its own wireless network to support its wireless controller, and transmitters and receivers are throwing up their own wireless networks much like your wireless internet. This can result in signal issues, such as audio and video occasionally flickering out for a brief period of time every few minutes before the connection stabilizes.

To spread things out, get all those wireless transmitters away from each other, maybe on their own shelves or in their own corners of the room. Luckily, though, being able to put the hardware wherever you want is the thing that a wireless HDMI extender specifically excels at.

Compare Wireless HDMI Extenders and Streaming Sticks

In the last few years, an alternative has emerged that is even more drop-dead simple to use: content streaming sticks. These include the Chromecasts, the Roku Sticks, and Amazon Sticks.

The absence of video signal encoding and decoding is the main distinction between streaming sticks and wireless HDMI extenders. These wireless streaming sticks, on the other hand, establish a direct connection with your wireless internet and stream content to the screen as necessary.

There are a few reasons why a streaming stick would be preferable than a wireless HDMI extender. First, they are simpler to use, with apps and physical controllers that are familiar and intuitive. Second, it is usually 5–10 times cheaper than any wireless HDMI solution. However, all these streaming sticks use your internet.

But if you are worried about data caps, or if you are in a location where you can’t get streaming speeds over Wi-Fi, then you’ll have to use the wireless HDMI option.

Conclusion

Wireless HDMI extenders help solve some problems like irregular hardware placement and keeping things tidy, the investment in wireless video is worth it. After all, you don’t want to be running tens of hundreds of feet of cables through your walls and ceiling. Use wireless video to keep things easy. That simplicity will be something you won’t regret once you’re up and running.

AV Access has an innovative wireless HDMI extender – HDW100. It can wirelessly extend 1080P full HD HDMI signal up to 200m/656ft in an open field, and 10m-50m (32ft-165ft) through an interior drywall. Click to learn more.

HDR Formats Types: HDR10, HDR10+, Dolby Vision and HLG

Most new TVs have the ability to display HDR content, which has more detail in the bright and dark areas of the image, for a greater “dynamic range” compared to non-HDR content. Billed as a way to get brighter colors and a better image, HDR essentially allows you to get brighter images and more vibrant colors — as long as the screen and the content support the tech.

But what exactly is HDR? And what’s the difference between HDR formats? From HDR10 to Dolby Vision, here’s everything you need to know about HDR.

What is HDR?

HDR stands for “High Dynamic Range”. It is a technology that produces images with a large perceptible difference between bright and dark regions. This capability achieves lifelike images and preserves precise details in lighting variations and gradations for realistically bright or dark pictures without subtle detail loss.

There are a number of different types of HDR that you’ll find on displays these days. The most popular include HDR10, HDR10+, Dolby Vision, and HLG. Next, we will have a closer look at them.

What is HDR10?

Supported by everything

Better image quality potential than Standard Dynamic Range (SDR), but perhaps not as good as HDR10+ or Dolby Vision

Static metadata

HDR10 is the most common and popular type of HDR, since it is an open standard and is used by a huge range of streaming services, including Netflix, Disney+, Apple TV+, and more. Also it is free to use for manufacturers, so it can be decoded by any HDR TV and streamed by any HDR streamer.

HDR10 uses something called “static metadata.” This means that there’s one HDR “look” for the entire movie or show. This is certainly better than SDR content, but it doesn’t allow for, say, a really bright scene to look its absolute best, nor a dark scene its best, within the same movie. The advantage of that is that it takes up less bandwidth than a format like Dolby Vision, which can send metadata frame-by-frame.

What is HDR10+?

Championed by Samsung

Not widely supported

Dynamic metadata

Potentially better image than vanilla HDR10

As you probably figured from the name, HDR10+ is like HDR10… but plus. The plus in this case is dynamic metadata, improving on HDR10’s static. This means that on a per-scene — or even per-image — basis, the content can provide the TV with all the information it needs to look its absolute best. The only problem is that it’s a Samsung format. Although they promise that there will be no licensing fees, it is still a bit of stumbling block.

Although there are many TV manufacturers producing HDR10+ compatible TVs, content and other devices are not as prevalent. The intention is for it to become more popular over time and more competitive with Dolby Vision.

What is Dolby Vision?

Widely supported

Potentially the best image quality of all the formats

Less content than stock HDR10

Dolby Vision is a format developed by Dolby Labs. Since it’s a propriety format, Dolby Labs licenses it, which means that companies have to pay Dolby to use it.

Dolby Vision offers a number of clear advantages over other HDR formats, making a big push for HDR. It supports 12-bit color, and a theoretical maximum brightness of a hefty 10,000 nits, so it is much more future-proof than other HDR standards.

What is HLG?

From BBC and NHK

Free to use

Broadcast friendly

HLG, or Hybrid Log-Gamma, was created by Britain’s BBC and Japan’s NHK. Unlike the formats we’ve discussed so far, it’s actually backward-compatible with SDR TVs. HLG is likely better than SDR, but perhaps not quite the picture quality of the other HDR formats, since it can’t do much to the black levels of an image — so you won’t really get much better detail in shadows and night scenes.

HLG is still in its infancy, and as a result, there isn’t much HLG content out there. We’ll have to wait and see if that changes over time.

Conclusion

Ultimately, the difference between the formats isn’t that important. The quality of the TV itself has a much bigger impact on HDR. There are limitations with HDR, though, because TVs can’t reach the 10,000 nit peak brightness and all the colors HDR is capable of, but most TVs still deliver a satisfying HDR experience.

Look Your Best on a Video Call: 7 Tips You Can Apply

In today’s age of remote work, video calls have become a necessary means of communication. Whether you are conducting a business meeting, attending a virtual event, or catching up with friends and family, video calls have become an integral part of our daily lives.

However, with video calls, it’s not just about what you say, but how you look and sound. In this blog post, we will share some tips on how to look your best on a video call, so you can present yourself in the best possible light.

Dress Appropriately

It may seem obvious, but dressing appropriately for a video call is crucial. Even if you are working from home, dressing professionally or semi-professionally can help you to feel more confident and presentable. Choose clothing that is comfortable and fits well, but is also appropriate for the setting. Avoid wearing clothes with busy patterns or bright colors that can be distracting on camera.

Choose a Neutral Background

The background behind you can have a significant impact on how you appear on camera. Choose a neutral background, such as a plain wall or a bookshelf, to avoid distractions and keep the focus on you. Avoid busy or cluttered backgrounds that can make it difficult for others to concentrate.

Use Angles to Your Advantage

Angles play a significant role in how you appear on camera. Position your webcam at eye level or slightly higher to create a more flattering angle. Avoid positioning the camera too low, as this can make you appear unflattering and distorted. Make sure you position your camera at eye level and adjust the angle to show your best side. You can also experiment with different angles to find the one that works best for you.

Have Appropriate Lighting

Good lighting is essential for looking your best on camera. Make sure you are well-lit, but avoid harsh overhead lighting that can cast shadows on your face. Position yourself in front of a window or use soft, diffused lighting to create a more flattering look.

Mind Your Body Language

Body language can convey a lot about your confidence and engagement during a video call. Sit up straight and maintain eye contact with the camera to show that you are present and engaged. Avoid fidgeting or slouching, as this can make you appear unprofessional.

Upgrade Your Webcam to High-Resolution

If you are using an older webcam, it may be time to upgrade to a high-resolution model. High-quality webcams produce a clearer, sharper image, which can help you to look your best on camera.

AV Access BizEye80 4K AI Webcam, for example, is an excellent option for those who want the best video quality. It provides 4K Ultra HD video resolution and a high frame rate of up to 720P/90fps.
