Things to Consider When Browsing the TVs With 4 HDMI Ports

When shopping for a TV with 4 HDMI ports, there are several things to consider to ensure you get the best value for your money. Here are some important factors to keep in mind:

Screen Size and Resolution

Screen size and resolution are two of the most critical factors to consider when buying a TV. Larger screens provide a more immersive viewing experience, but they also require more space and can be more expensive.

Additionally, resolution plays a vital role in image quality, and 4K resolution is now the standard for most modern TVs. However, 8K resolution is becoming increasingly common, so you may want to consider future-proofing your purchase by investing in a TV that supports this resolution.

Connectivity Options

When browsing for a TV with 4 HDMI ports, it’s important to consider the other connectivity options as well. This includes features like Wi-Fi, Ethernet, and USB ports. Additionally, you may want to ensure that the TV supports the latest HDMI standard (HDMI 2.1) to ensure compatibility with the latest devices and to take advantage of the latest features.

Did you know that you can mirror your phone to a TV without Wifi?

Smart TV Features

Most modern TVs come with smart features that allow you to access online streaming services and other internet-based content. It’s important to ensure that the TV you purchase supports the streaming services you use most frequently. Additionally, some TVs come with built-in voice assistants, such as Alexa or Google Assistant, that allow you to control your TV with voice commands.

If you happen to get a new TV that doesn’t have a remote with it, don’t worry because there are other ways you can turn on your TV.

Audio Quality

While many people focus on picture quality when purchasing a TV, audio quality is also an important consideration. Some TVs come with built-in speakers that deliver high-quality sound, while others require external speakers or soundbars to achieve a similar level of audio quality. Be sure to consider the TV’s audio capabilities and any additional equipment you may need to purchase to achieve the sound quality you desire.

Gaming Features

If you’re a gamer, you may want to consider a TV with features specifically designed for gaming. This includes things like a low input lag, high refresh rate, and variable refresh rate technology, all of which can improve your gaming experience. Additionally, some TVs come with features like auto game mode, which automatically adjusts the TV’s settings for optimal gaming performance.


Finally, price is an important consideration when browsing for a TV with 4 HDMI ports. While it’s easy to be swayed by all the features and options available, it’s important to stick to your budget and purchase a TV that fits your needs and price range. Keep in mind that prices can vary significantly based on screen size, resolution, and features, so be sure to shop around and compare prices before making a final decision.

What is HDMI 2.

1. And is it needed in 2021?

There are more and more devices with the new connector: PlayStation 5 and Xbox Series X consoles, new NVIDIA and AMD video cards. It seems that HDMI 2.1 is simply necessary for the new generation, but is it really so?

The new generation PlayStation 5 and Xbox Series X consoles are equipped with an HDMI 2.1 output and can, according to the manufacturers, play content in 8K and, much closer to the masses, 4K at 120 frames per second. But for this you need an appropriate TV. It is believed that in an ideal TV for new consoles, HDMI 2.1 should be required.

In addition to console manufacturers, AMD and NVIDIA have also caught up: their new video cards are also equipped with modern HDMI 2. 1. However, to connect to monitors with a high refresh rate, video cards have long had a Display Port connector.

However, HDMI 2.1 is still not found in every TV. A modern connector is usually installed in more expensive models, and there are a lot of owners of 4K TVs with HDMI 2.0 now. So is it worth paying more?

How HDMI versions differ and why it matters

HDMI is the main way to connect modern video equipment to a TV. Analog connectors have almost sunk into oblivion: they remain in TVs except to maintain compatibility with older devices.

In the past, picture quality often depended on the price of analog cable—expensive cables were typically thicker, more resistant to interference, and provided better picture quality. The digital signal is always the same and the cost of the cable does not play a significant role. The main thing is that the cable is in principle serviceable. However, in reality this is not entirely true. Image quality still depends on the cable, albeit in a slightly different sense.

Premium is not empty marketing. The fact is that HDMI cables, in fact, do not have versions, only certification plays a role. If the cable can transmit a 4K @ 60Hz signal, then it is called Premium

It’s all about versions. Like the USB interface, HDMI has gone through many revisions, from the first version in 2002 to the most modern version 2.1 at the moment, announced in 2017. The main difference between versions has always been primarily throughput, measured in gigabits per second.

So, the main feature of HDMI 2.0 before its predecessor HDMI 1.4 was the ability to output video in 4K at 60 frames per second, instead of only 30 frames. Passport throughput in this case is 18 Gb / s versus 10.2 Gb / s. But over time, even this is not enough, which leads to the emergence of new standards.

HDMI 2.1 benefits

Resolution and frame rate. The most important advantage HDMI 2. 1 has over its predecessor is the ability to transmit 4K at 120 fps and 8K at 60 fps. The still exotic 5K and 10K are also supported.

This feature is heavily advertised for gamers. 60 frames is now considered the minimum comfortable even for calm single-player games, not to mention fast-paced or competitive multiplayer games. The frequencies of gaming monitors and gaming laptop displays have long overcome this barrier towards 144 Hz, 240 Hz and even 300 Hz.

When it comes to 8K and above, despite the increasing number of TVs with this resolution, there is still little content. Even in 4K, there is still not much content – most movies and TV channels are broadcast in Full HD.

Dynamic HDR. Simply put, HDR (high dynamic range) makes the dark areas of an image darker and the light areas brighter. Due to this, the picture becomes more saturated. Dynamic HDR is different in that the metadata needed to display the content correctly is transmitted for each frame.

Screenshot of PlayStation 5 settings. Due to HDMI 2.0 bandwidth limitations, the 4K@60Hz HDR signal is in YUV 422 format, but this is not critical for a game console.

Dynamic HDR also works on HDMI 2.0, but subject to bandwidth limitations. Dynamic HDR includes, for example, Dolby Vision and HDR10+.

Enhanced Audio Return Channel (eARC). Improved audio return channel. Simply put, Audio Return Channel is the sound output from the TV to the receiver or soundbar via HDMI. Its more advanced version, Enhanced Audio Return Channel, allows you to transmit high-quality multi-channel audio in formats such as DTS Master, DTS:X, Dolby TrueHD, Dolby Atmos and others.

Auto Low Latency Mode (ALLM). Automatic low latency mode. In modern TVs, as a rule, there is a mode in which post-processing of the image is turned off, which makes the picture smoother and improves its quality. Movies and video content do look better, but in games where instant response to player actions is important, this only gets in the way.

That’s why TVs have a “Game Mode” that needs to be turned on manually. In the HDMI 2.1 specifications, this function is given to automation – the game console tells the TV when to activate the low latency mode and when it can be turned off.

Variable Refresh Rate (VRR). Variable frame rate. When the frame rate rendered by a game console or computer does not match the refresh rate of the monitor, the so-called tearing occurs – the image becomes torn. Essentially, you only see part of the new frame. This happens because the hardware cannot provide a stable frame rate due to lack of performance.

This does not happen with variable framerate, as only fully rendered frames will be displayed. Roughly speaking, the display frequency adjusts on the fly to the capabilities of the hardware on which the game is running. This is especially important at high frame rates, when it can be difficult for the hardware to maintain stable performance.

The function is really useful. Similar AMD FreeSync and NVIDIA G-Sync technologies have already proved their worth.

Quick Frame Transport (QFT). The technology allows to reduce the input lag by optimizing data transmission over the cable. Simply put, the time it takes for a signal to travel from a source to a receiver is reduced.

Quick Media Switching (QMS). Can be translated as fast switching between signal sources. When switching between inputs or when changing the image output settings on the source, a black screen will inevitably appear for a couple of seconds until the TV adjusts to the new settings. With this technology, this delay should be a thing of the past.

4K@120Hz – what’s the catch?

In fact, the main advantage of HDMI 2.1 can be called support for 4K at 120 frames per second. And first of all, this mode is relevant for games. But there are nuances. The fact is that the power of the PlayStation 5 and Xbox Series X, as well as most video cards, is not enough to provide high frame rates in 4K resolution. Especially when it comes to ray tracing.

For example, Control Ultimate Edition on consoles runs at 1440p at 60 frames without ray tracing and 30 frames with ray tracing. It is worth noting that the picture is still displayed in 4K, and 1440p is the rendering resolution. That is, in most graphically advanced games, at best, you should expect 4K at 60 frames per second, and HDMI 2.0 is enough for this.

Native 4K at 120 fps is only achievable in undemanding titles like Monster Boy and the Cursed Kingdom.

However, there are already games that officially support 120 FPS mode. However, this does not change the essence of the matter. According to Digital Foundry, in the console version of Nioh 2, the resolution ranges from 792 ₽ to 1080 ₽ and the graphics are rather poor. Even if the console menu is set to 4K, rendering still occurs at a lower resolution. In this case, there is no particular point in 4K, the picture will still be soapy.

The good news is, if your TV or monitor with HDMI 2. 0 supports a 120Hz refresh rate at 1080p, then you will be able to enable 120 FPS mode on PS5 or Xbox Series X. Considering that at this frame rate, games will still run at resolutions below 4K, you will not feel much difference in picture quality.

Computer hardware is a little better. Graphics cards like the RTX 3080 and 3090 can actually run well-optimized or undemanding projects in native 4K at frame rates above 100.

In addition, DLSS technology is of great importance, which significantly increases performance even on weaker cards. The same Nioh 2 produces about 90 frames per second already on the RTX 3070.

DLSS works only on NVIDIA graphics cards, but AMD has its own equivalent in development – FidelityFX Super Resolution. The technology will work both on Radeon graphics cards and on consoles. There is no exact launch date yet. However, on consoles, you should expect support for 4K 60 FPS + ray tracing than at 120 FPS.

How to tell if an HDMI 2.1 port is “fake”

The presence of an HDMI 2.1 port in the specifications does not in itself guarantee that all the claimed benefits will work on a given TV. The ability of the interface to transmit 120 frames in 4K does not mean at all that the TV matrix is ​​capable of reproducing them. If the matrix by characteristics has a refresh rate of only 60 or 100 Hertz, then this will be the maximum frame rate for the signal.

Simply put, if the specifications say HDMI 2. 1, it means that only some functions can be implemented. Before buying, you need to make sure that the features you need, such as 120 frames per second, are really present.

LG SM8200PLA TV Specifications. Screenshot: lg.com

It also happens vice versa, there is no mention of HDMI 2.1 in the specifications, but there is support for some characteristic functions. As a rule, these are functions that do not require large bandwidth: VRR, ALLM, eARC. For example, in TV 2019LG SM8200PLA announced support for ALLM.

Difference HDMI 1.4 from HDMI 2.0, HDMI 2.0a

For more than a decade, the HDMI connector has been the most common high-definition signal transmission standard. The choice in its favor was made by almost all market participants, thanks to availability, support for all modern technologies and constant development. Developers of HDMI adapters are constantly improving their brainchild, providing manufacturers and users with the very best that the AV industry has achieved.

HDMI switching is updated more often than other AV signal transmission standards, and sometimes this creates certain difficulties for ordinary users. From version to version, trying not only to keep up with the times, but to set the development vector, the developers add more and more new “features” to the standard.

When it’s something revolutionary, the new version is assigned an ascending number (1, 1.2, 1.3, 1.4, 2, 2.1), and when it comes to expanding existing functionality, an alphabetic value is added to this number (1.2a, 1.3 a, 1.4b, 2.0a, etc.). Today I would like to tell you what is the difference between HDMI 1.4 and HDMI 2.0, HDMI 2.0a (b) and other versions that are not related to 4K resolution.

Current HDMI Versions

Today, the current version is HDMI 2.0 (a/b), which was officially announced on September 4, 2013. Equipment with its support began to appear on sale in 2014, and now this interface is already on board many devices.

But this does not mean that devices with support for earlier versions should be thrown away. Not at all! As you will see from the tables below, for the average user to watch satellite / cable / terrestrial HD TV channels and movies, and for laptops and home computers, HDMI 1.2-1.4 will be enough.

Although, of course, the version 2.0 specification contains more “goodies” with an eye to 5-7 years ahead. But running ahead of the locomotive and now trying to look for a TV with HDMI 2.1 “on board” is absolutely not worth it. It has simply not yet been produced, because it was presented only at the beginning of January 2017. So, let’s proceed to a detailed study of the specifications of various versions of HDMI …

The main characteristics of HDMI of different versions

Let’s turn to the main characteristics of different versions of HDMI, and most importantly, find out what is the difference between HDMI 1. 4 and 2.0 (the most current versions). Note the almost fivefold increase in throughput of the latest version compared to version 1.4.

This data from the official HDMI specification says little to the average user. Much more often people are interested in what resolution and frame rate the standard supports, because it is these data that are widely advertised by manufacturers of TVs, monitors, computer hardware and other equipment, and are also indicated in the characteristics of games and video files.

Maximum HDMI support frequencies and resolutions

Now that’s more interesting! And it’s more interesting because the lion’s share of consumers wants to know not data on TMDS or color depth, but “will the new video card pull 4K”, or “can I watch Full HD channels on this TV”, etc.

As you can see, almost the full potential of Full HD, which is quite enough for a simple viewer, was revealed in HDMI version 1.3-1.4. It is with a resolution of 1920 × 1080 HD TV channels are broadcast.

4K content is quite possible to watch (or play) already on equipment with HDMI 1.4 support, however, only at a frequency of 30 Hz. But a huge number of people do not even know about some kind of Hertz … HDMI 2.0 and higher gives a huge increase in resolution, bandwidth, and frames. But is it necessary right now? To whom and for what?

Supported HDMI functions of all versions

Now let’s talk about the HDMI functions supported by different versions.
In version 1.4, everything most needed (3D, ARC, CEC) is already available, and what is introduced, starting from version 2. 0, looks rather redundant for most users. Judge for yourself: HDMI 2.0 has Full HD 3D at 120fps, 4:2:0 chroma subsampling, 25fps 3D formats, and HE-AAC and DRA audio standards.

And in fact: few people are interested in 3D anymore (this year Samsung and LG have curtailed the production of 3D panels, other manufacturers will soon follow them). 4:2:0, DRA… “What is this?” – ask 95% of buyers, and what really matters is only support for 4K at 60 frames per second (FPS).

Protecting HDMI ports

What really matters is protecting HDMI ports from burn-in. Here, unfortunately, no new version of the standard will save … HDMI ports were on fire from “hot plugging”, i.e. connections without de-energization, and they burn. Although manufacturers are trying to somehow alleviate the situation by adding additional protection to the circuits of their devices, this does not always help. This happens because there are quite high (about 100 volts) static potentials on the device cases.

Protecting HDMI interfaces Dr.HD HDMI Protector

When devices are connected, these potentials are equalized (discharge), resulting in equipment damage. This problem has been known since the very beginning of the appearance of the HDMI interface. All this is a consequence of the general cheapness of components. Such is the circuitry … It doesn’t matter who the manufacturer of your TV or video card is. The problem lies in the interface itself.

Therefore, whatever version of HDMI your devices support, they should be switched only when all devices in the circuit are disconnected from the socket! If this is not possible or you just want to additionally secure expensive equipment, you can (and sometimes need to) use HDMI protection. Such devices can be easily bought in specialized stores.

Such passive elements (in other words, fuses) will protect equipment with HDMI interfaces from electrostatic discharges, potential difference when connecting equipment “hot”, as well as lightning. They are active on all TMDS channels and will act as the ultimate ESD protection. If suddenly the discharge goes through the cable, the defender will take the whole blow on himself.

In conclusion

So, I hope we managed to clarify not only the difference between HDMI 1.4 and HDMI 2.0 (a / b), but also other versions of the HDMI standard. Now you know that it makes no sense to try to set the resolution to 4K on your new video card if you have an old monitor, and you can watch satellite HD channels in excellent quality on a TV with the very first version of HDMI.
