The two main 3D technologies on offer today – which one should you choose?

Today, you don't always have to go to the cinema to watch a 3D movie. Three-dimensional images can be reproduced by new generation TVs that support 3D. You just need to purchase a DVD with a stereoscopic effect, which will cost you a little less than a movie ticket. If you have already purchased a TV that supports this function, then you are only a few steps away from watching a three-dimensional movie. So, how to enable 3D mode on your TV?

How to watch 3D on TV from an external hard drive

3D TVs are now becoming increasingly popular. Many people know how to connect and configure them correctly, but for some, figuring out the configuration is quite difficult. Also, many questions arise when connecting different types of 3D glasses. When viewing three-dimensional images from an external drive, the main problem that arises is the inability to display the images. This arises because you want to watch a movie directly from a flash drive or disk, and it should be converted using a special audio/video converter and the filters offered for it. Most often, TVs themselves transform the image, but when such problems arise, the solution lies precisely in the wrong format. If you have problems with sound, try finding the movie on another resource. After converting the format, insert the USB flash drive and turn on 3D viewing again.

Types of 3D image playback

The main division of three-dimensional video playback technologies involves three categories. It is impossible to safely say that one or another of them is better than other types due to significant technical differences used to create a 3D image.

1. Anaglyph. This technology is familiar to almost everyone - glasses with multi-colored lenses. The advantage of anaglyph reproduction of a three-dimensional image is the ease of manufacturing 3D glasses. At the same time, this does not mean that the better the screen, the better the picture. After all, the problem with accurate color reproduction present in modern-generation TVs from all manufacturers, including LG, makes the use of anaglyph glasses impossible.
2. Shutter. The essence of transmitting a volumetric 3D image using this method is to alternately change the “seeing” eye. Support for this type of 3D technology requires the use of special glasses with LCD lenses. Using a built-in power source, they actively change the transparency of each lens one by one at high speed.
3. Polarization. Its operating principle is based on the capabilities of the image polarization effect. The glasses themselves select which image is transmitted to the selected eye, and no power source is required for their operation.

Before settling on a specific option, it is best to try them all one by one. This will allow you to choose the most optimal option for using LG technology without unpleasant consequences for your eyes.

How to watch 3D on TV from a computer

You can also enjoy 3D images through your computer. To do this, you need to make sure that the computer has enough resources to do this. It must meet basic requirements, which are the availability of free memory, a specific operating system, etc.

Next, connect your computer to the TV via the HDMI1.4 connector. You will then be prompted to select it as your primary monitor. Make an ISO image of the movie you recovered. Next, we edit it through Alcohol 120% or Diamond Tools and watch through one of the players:

• Stereoscopic player;
• Cyberlink Power DVDultra 12.

In the player we find the 3D viewing mode, put on the glasses and enjoy the spectacular picture, like in a cinema.

Which 3D playback system is safer for the eyes?

People's opinions are divided on which of the modern technologies created for viewing 3D video is better. The pros and cons of the systems are actively discussed, and the opinions of doctors and world experts are given. But, in fact, 3D rips for any 3D technology existing today are absolutely the same. The difference in the picture lies only in the quality of production and the hardware model of the screens installed in the TVs, as well as the selected 3D glasses. After all, three-dimensional images can also be viewed on LG projectors - but this technology does not have screens.

There is an opinion that the passive model of glasses is safer for the eyes than the active one. But there are some nuances here. The first version of the glasses does not put as much strain on the eyes and, at the same time, all the flaws of half resolution are visible on the screen. In the second option, active lens switching, some people are able to see. Unfortunately, this means that they will have to stop using them - or endure this inconvenience. At the same time, these glasses provide a better picture, although they put strain on the eyes.

All of the above means: it is impossible to confidently say that the first or second type of glasses is better. The main issues are the length of time of continuous use of special lenses and the user’s requirements for picture quality.

How to watch 3D on TV using a player

Most current players read all 3D formats. But it is important to consider that even the latest version players have their own shortcomings and shortcomings that can cause viewing problems. Connect the player to the TV via HDMI1.4 connector. If you use a harddisk as a storage device and connect it via USB, this can cause a lot of troubles, including freezing of movies and problems with sound. You can resort to a proven method: burn the movie to a Blu-ray disc, and then you can watch it through the player. A description of the main problems with playback through the player, as well as ways to solve them, can be found in the instructions for using the player.

Time spent using glasses is an important indicator

No matter how actively they convince you that certain 3D glasses are ideal for specific LG equipment, this is not the case. The right question is not “which is better,” but “how long can you use them” and “what will be the picture quality?” Distance to the screen, eye fatigue before watching, stress - many, without taking these factors into account, declare that the chosen type of glasses is bad. This doesn't mean it's actually true, but sometimes it confuses other people. Therefore, remember - the visual system of each person is unique, and sometimes individual selection of the distance to the screen, the intensity of room lighting and customizing the standard factory settings in the technology used can help solve any problem of “low-quality” images in 3D format.

How to connect 3D glasses to TV

Most often, special glasses already come with the TV, but if you bought them separately, check them for compatibility. To turn on the 3D glasses, go to the TV, press and hold the power button for three seconds, and then again when you turn on the 3D movie.

TVs with 3D effect can make watching any movie more interesting and exciting. You will be able to watch films, cartoons and video clips in a completely different quality. To do this, you just need to set the mode correctly, and our advice will definitely help you with this.

Production of 3D TVs has ceased, 3D television is dying

Although, I’ll say right away that I’m not at all worried about this miracle. But read to the end and everything will become clearer and clearer that this is me.

Just the facts!

Reduced sales of 3D TVs and players indicate that buyers are now guided by other criteria when making their choice. It is unlikely that these or other users will want to get 3D TVs or players again in the near future.

So we shouldn’t expect a revival of this trend in the coming years. Of course, there are still adherents of 3D, but there are fewer and fewer of them. I responsibly declare that a TV with 3D function support is no longer interesting even to those who own it.

According to the owners, they tried their new product 1-2 times, after which they stopped using it. Just like me!

But why?

And so we’ll figure it out thoroughly

Firstly

3D TV of new formats 3D TV is a double-edged sword. For it to truly become widespread, it is necessary not only to update the corresponding fleet of subscriber equipment (TVs), but also operator equipment (TV set-top boxes or set-top-boxes).

Secondly

3D glasses are active and passive, but this still interferes with viewing. Previously (about three years ago), when choosing a modern TV in the middle or premium price categories, you received support for 3D technology. I have already written about this topic, look here .

Thirdly

In the development of 3D television, the readiness of the TV operator to broadcast such 3D content plays a role, as well as the availability of the most special 3D content, such as films, programs, and this is a problem for 3D.

Simply, there are not enough gears. And there will be no more of them, for the reason of indecency!

From the point of view of artistic perception, the 3D format is incompatible with films where the plot is based on revealing the inner world of complex characters. In a word, it’s bad, in fact everything is critical. Let me remind you that NTV+ has stopped broadcasting its only channel in 3D.

And how wonderful it all started!

I remember it was even announced that a new era of three-dimensional television had arrived. Any TV with 3D function was much more expensive than its analogue. It even got to the point of ridiculousness; manufacturers of tablets and phones began to produce 3D devices.

However, the common sense of the buyer prevailed and they were not particularly popular, and over time, sales of 3D TVs began to fade. Several large companies have announced that they will stop producing 3D TVs.

Samsung was one of the first to report this.

Its representatives stated that very little content is produced for 3D, so users cannot fully enjoy the three-dimensionality of the “picture”. And they slyly added that there was simply no point in releasing TVs with a 3D function without the ability for viewers to use this function.

In principle, everything was explained by the fact that 3D TVs, almost immediately after the boom, simply stopped being bought. After Samsung, Philips made a similar statement, whose management directly said that no one needed 3D.

In particular, LG made such a statement. They have decided to stop making 3D TVs in 2021 so they can concentrate on HDR, a much more versatile technology.

High Dynamic Range Imaging, or simply HDR, is the name of technologies for working with images and videos, the range of brightness of which exceeds the capabilities of standard technologies.

At about the same time, Sony announced the release of only two 3D TV models this year.

But I came to my senses in time!

Just the other day, Sony announced a complete cessation of production of televisions of this type. None of the new models, including the most expensive ones, will support 3D mode.

In addition to the companies mentioned above, lesser-known manufacturers, including Vizio, TCL and Hisense, have also stopped producing 3D TVs. By the way, none of the companies presented a new 3D TV model at the Consumer Electronics Show.

Features like 4K and HDR have become much more in demand and this, along with screen size, is now a key factor in buyers' considerations.

As you already know, I have become a fan of UltraHD 4K television, although I also have a 3D TV but do not use the 3D functions. I suggest reading about the prospects for the development of Ultra HD 4K until 2019.

Good luck, Friends!

View 3D home

For home viewing, you can choose inexpensive and lightweight anaglyph glasses. To convert a horizontal/vertical stereo pair, you will need special programs. Such applications pre-process downloaded videos or work with the image as they are viewed. As a result, using a regular monitor (such as LC24F390FHIXCI) + special. glasses + program, you can watch 3D movies.

Review of popular software solutions

There are free and paid options. But they must first be installed on the device you are using.

Let's look at the features of popular programs:

Stereoscopic Player

It resembles a regular media player, which is designed for viewing content with a stereoscopic image. The program independently converts a 2-dimensional image into 3D.

Users have access to:

• standard tabs - file, view, playback (on the top panel);
• video control - start, pause, stop, select mono or stereo image. You can change the left/right angle ratio (at the bottom of the utility).

sView

Easy to use and functional program. Installs on devices with any operating system: Windows, Linux, Mac, Android.

There are several tabs on the top panel:

• media - you can open an image from one file. Or select left and right, and also select the desired stereo format;
• view - adjusting aspect ratio, panorama, working with colors. You don’t have to change anything in this section if you are satisfied with the picture on the screen;
• anaglyph glasses - you need to select a device and decide on the type of glasses (red-cyan, yellow-blue, green-purple) and the type of filters.

Bino

The program takes up minimal space on the device and has basic functionality for viewing 3D content.

Peculiarities:

• You can open several files at once. For example, if the left and right video sequences are recorded in different docks;
• adjust colors, quality, sound, subtitles, etc.

Standard options are also available, such as video rewind, pause, and repeat mode.

MakeMe3D

The utility automatically converts 2D content into 3D. Supports importing files from popular formats: MP4, DVD, AVI, etc. You can convert several videos at once. Using manual settings, you can adjust the brightness of the picture, adjust the depth of the 3D effect, and frame shift.

Axara 2D to 3D

Creates three-dimensional video based on standard 2D films. Automatically converts video and saves it in formats suitable for viewing on various devices: DVD, Xbox, iPod, etc. The program allows you to change the video size, resolution and frame rate. The feature of the application is the ability to extract and save sound from the content being played.

A 7-day demo period is available. Then you will have to pay to use the program.

Note: How to connect a tablet to a TV or monitor: 7 methods for all occasions

The table describes brief information about popular video converters:

You can download and test every program. The choice depends on personal ease of use and the availability of the necessary functionality.

A caveat : the quality of the picture obtained using such programs will be worse than that of a movie shot in 3D. But it will be possible to watch movies in 3D on a regular monitor. Like G24C4.

Is it possible to watch 3D on a regular TV?

TVs with 3D glasses are almost not sold in 2021, but some users still want to watch 3D movies, because the content is still available on the Internet to this day, and is also sold on discs. 3D on a regular TV , but several conditions must be met.

• High resolution – FHD minimum, 4K ideally.
• The frame rate is at least 120 Hz.
• Availability of content encoded accordingly.
• Availability of glasses.

It was described above how different 3D technologies work. Active requires certain “skills” from the TV, which create a stereo effect, that is, regular TV cannot do this. But passive technology and anaglyph will do. The last option is the simplest - just download the 3D movie and find glasses or make them yourself from cardboard and transparent colored plastic. Actually, such 3D was known back in the times of the USSR with the first color televisions. It does not even require compliance with the above conditions. For those who want to watch high-quality 3D, you will need not only passive polarized glasses and appropriate content, but also a suitable TV.

Important! Why minimum FHD? The image of passive technology is divided into two parts, that is, each eye receives not an FHD image, but an image in a lower resolution. The situation is similar with the update frequency. 120 Hz, because each eye receives a frequency of 60 Hz, and this is the minimum for comfortable viewing.

Another interesting segment

But the 3D industry market doesn't end with just films. Many people interested in buying a new TV are not interested in cinema...

Of course, we are talking about gamers! They are primarily looking for the best 3D TV not for cinema, but for entertainment with the possibility of almost complete immersion in the virtual world. This was facilitated by the release of two favorite consoles – Xbox One and PS4. A kind of dream that unites modern schoolchildren and guys over thirty! And even if the range is not yet broad and cheap, there is room for growth. Many games have been announced for release in 3D. Well, let's wait...
