Frequently Asked Questions: 40 Inch Smart TVs

What is a 40 Inch Smart TV?

A 40-inch Smart TV offers intelligent functions and allows direct Internet access, among other things. Thus, it is not a classic TV, but the modern variant.

The innovative extras simplify operation and make it possible to watch shows time-shifted or retrieve them via the online media library. You can also rent movies from the online video store and stream them directly. Once you have connected your 40-inch Smart TV from the test to the Internet via Wi-Fi or with the help of a cable, the online functions are available at any time.

The additional interface for LAN Internet or WiFi access can be provided by a stick in many new smart TVs. Typically, the 40-inch Smart TVs from the test have a few more connection sockets so that USB sticks and other connections can be used. This expands the possible uses from the Smart TV, which can be easily controlled via the apps. The apps are available in the corresponding library, which is accessed via the smart menu.

Most 40-inch smart TVs from the test were set up for the established streaming providers, so you won’t have any problems accessing Netflix, Maxdome or Amazon Instant Video. There can be some differences in the menu control. The newer smart TVs sometimes have voice control as well as easy-to-use touch controls. Meanwhile, more and more TVs can be connected with a keyboard, which also facilitates operation.

The new generation of 40-inch Smart TVs from the current test corresponds to the digital standard of today and thus proves to be very flexible. The Internet-enabled applications support the direct connection of TV, Internet and multimedia devices.

With a screen diagonal of 40 inches, such a TV is perfect for use in the living room at home. Converted, the diagonal is just over 1 meter long.

How does a 40 Inch Smart TV work?

The typical 40-inch Smart TV from the comparison test is a multifunctional device that bridges the gap between TV and computer. The Smart TV supports non-linear TV, because you can access the media libraries of the individual channels via Internet access and also surf online directly. Videos on YouTube are available as well as the comprehensive streaming offer.

Whether it’s the favorite series or blockbusters recently made available by video stores, the user decides when the show starts.

Many of today’s 40-inch Smart TVs work via WiFi, so you don’t need a LAN cable to connect to the Internet. After establishing the wireless connection, one simply accesses the online videos and no longer needs to adhere to the specified broadcast times.

Not all current 40-inch Smart TVs come with the Internet functions pre-installed. In this case, you need a streaming box to access the online content. The ports on the Smart TVs also give you the option of connecting your smartphone or laptop to the TV to watch movies or pictures on the larger TV screen.

One of the useful functions of the 40-inch Smart TV test winner is the time shift. This records the current TV program and stops playback if you are disturbed or want to take a break. Later, you press the button again when you want the program to continue.

The program is stored continuously on the TV’s internal memory, so you never miss a scene. Depending on how large the built-in memory is, it can make sense to connect an external hard drive. This is also useful when recording complete movies or shows that you only watch after a longer period of time. During programming and saving, users are supported by the electronic Program Guide.

This contains the important information about the broadcast program. If you install a Smart TV app on your smartphone, operating it becomes child’s play and you save the awkward typing via the classic remote control.

Advantages of 40 Inch Smart TVs

With a 40-inch Smart TV, you have found the ideal centerpiece for the TV corner. The pleasant size fits in the living room or even in a not too small teenager’s room. While the smaller TVs with only 32 or 34 inches have certain limitations, the 40-inch Smart TV from the test collects many plus points with its picture quality.

The HD resolution of the current test winners in the 40-inch Smart TVs only comes into its own when the screen is also large enough. However, it does not necessarily have to be the XXL TV with 55 inches or more, because the viewing experience becomes too exhausting in the long run if you sit too close to it.

The usual outer dimensions of a 40-inch Smart TV are about 90 cm wide and 50 cm high. The screen diagonal of 40 inches or around 101 cm is usually accompanied by a frame. This should be taken into account when selecting a Smart TV to avoid problems when setting it up.

With their modern processors, the current 40-inch Smart TVs from the comparison test are very powerful, which is reflected in the shorter access and response times.

When you pick up the remote and make settings, the desired adjustment is made immediately, whether it’s the brightness of the picture or a program change. With the test winners of the 40-inch Smart TVs, you can reach for your smartphone or a touch remote, so navigating is even easier.

A Smart TV is not only suitable for linear TV, but also for surfing the Internet, recording and time-shifting programs, and gaming. For this purpose, the 40-inch Smart TVs are equipped with various apps and a practical menu navigation. This allows users to quickly access their favorite sports shows, the media library or streaming services.

Consumers also increasingly have a pay TV contract that requires a smart card. This pay TV card is inserted into the designated slot and the user has direct access to the pay TV channels ordered.

The menu navigation favors the intuitive use of the customizable user interface. This is a visible improvement compared to the previous TVs.

It is worthwhile for prospective buyers to look at several operating systems to find the TV that best realizes their own wishes. The main focus is on the comfortable and error-free operation of the menus and buttons. However, the quality features and the design should also be kept in mind.

Types of 40 Inch Smart TVs

The 40-inch Smart TVs have a set screen size, but there are some other distinguishing features that allow categorization. Many of today’s Smart TVs have an integrated tuner. This means the reception technology is already inside the TV, so you don’t need a receiver. You simply plug the antenna cable into the socket for cable reception or connect it to the satellite system.

If it’s a Smart TV with a triple tuner, there are three reception modes to choose from. In addition, there is the interface for the CI+ card, which is now available on all Smart TVs.

The 40-inch Smart TVs can be devices that access the Internet via a cable connection or work with WiFi. For the cable connection, a LAN interface must be available on the TV in any case. A WiFi-enabled TV works wirelessly.

The television transmission technology must also be taken into account. Classic cable TV works with the appropriate cable connection, which may have to be installed first. However, today’s homes often already have several connections.

The cable providers pay a monthly fee for this cable connection. In return, consumers have access to many programs, but in addition to the jack, they need a receiving device, i.e., a receiver.

Satellite TV, which is somewhat more susceptible to interference than cable TV, offers even more programs. In addition, users have access to modern HD quality, even if they have to pay more money for this extra with the private broadcasters. Depending on the TV subscription in question, it is not always possible to record a program and watch it time-shifted via the time-shift function.

Traditional terrestrial television is now almost obsolete. DVB-T has significantly fewer transmitters than the other two transmission technologies, and reception is also somewhat more susceptible to interference. The introduction of the DVB-T2 standard has led to some changes that have a positive impact on picture quality and support ease of use.

The advantages of a 40-inch smart TV:

  • versatile use through smart functions,
  • high-quality picture,
  • easy connection options with other devices,
  • large TV screen to be used as a flexible monitor.

The disadvantages of a 40 inch Smart TV:

  • Higher price than a classic TV set,
  • Security risk due to integrated Internet technology.

How are 40 Inch Smart TVs tested?

The test of 40-inch Smart TVs examined which quality features are particularly relevant and what these devices are suitable for. If you watch TV in the traditional way, you don’t necessarily need Internet access. But this online connection opens up completely new possibilities and transforms the classic TV corner into a modern multimedia area.

Home cinema or gaming, many things are feasible with the new Smart TVs. The following criteria should be checked when making a purchase decision, so that your own wishes are fulfilled as well as possible, depending on the respective priority.


Indoor antenna, cable TV or satellite, the 40-inch Smart TV should match the existing reception type. Not every modern TV can be connected to DVB-T2. However, most of the devices in the comparison test are equipped with a triple tuner that is designed for all three types of reception. Furthermore, the integrated tuner eliminates the need for an additional receiver, so you only need a remote control.


The resolution is one of the important features for all screen devices. This is especially true for the larger TVs from 40 inches. Smart TVs today often have the Full HD standard, which is 1,920 x 1,080 pixels minimum. Even slightly larger TVs have even more pixels, but up to the screen size of 40 inches, Full HD quality offers sufficient resolution.

HD Ready, on the other hand, has a lower resolution of 1,280 x 720 pixels. The image dynamics and color brightness are directly related to the resolution.


Most 40-inch Smart TVs are equipped with an LED or LCD screen. These two types are based on the LCD principle and have a display that is composed of liquid crystals. The actual distinguishing feature is the illumination. In the case of LCD televisions, the image is generated by differentiated illumination.

For this purpose, individual phosphor elements are used, which illuminate the liquid crystals from the rear side. Due to this design, LCD sets are significantly wider than LED sets.

LED TVs work with light-emitting diodes that are located at the edge or just behind the screen (edge LED, direct or full LED backlight). Backlighting also requires a wider display. However, the edge LED can cause uneven illumination, resulting in a clouding effect.

The innovative OLED technology is not available for the 40-inch Smart TVs, but can only be found for larger TVs.

Refresh Rate

The manufacturers of the 40-inch Smart TVs from the test often advertise a high refresh rate, which is not always comprehensible. The standards of 50 or 100 hertz are perfectly sufficient for the 40-inch TVs, so you should not be confused by higher numbers. With the current screen technology, the sharpness of movement is displayed well so that no flickering is perceived.


First of all, you need a LAN port to connect the smart TV if it is not a TV with Wi-Fi. Furthermore, the modern 40-inch Smart TVs from the test are equipped with various other connection sockets. There are often at least two USB ports as well as HDMI and audio jacks.

For the frequent use of external devices like memory sticks, smartphones or cameras, even more USB ports might be worthwhile so that the connections do not have to be changed every time. If there are enough USB sockets, the hard drive can stay in its slot all the time. This makes it easy to save a recording at any time. The HDMI ports are suitable for connecting the notebook, an additional monitor or a gaming console.

Operating System

The operating system in the 40-inch Smart TV can be directly compared with the operating systems of PCs and smartphones. This is also referred to as OS (operating system). A look at the product data of the TVs shows that the manufacturers usually stick to one operating system.

Panasonic’s devices use Firefox, for example, while Samsung relies on Tizen and Sony on Android. A fourth operating system is Web OS, which is used by LG, for example.


In addition to the operating system, there are special apps for the TV programs. These applications are downloaded online from the corresponding OS store. For example, there are free or paid weather apps, program information, time and calendar functions, and games.

What should I look for when buying a 40 Inch Smart TV?

When deciding on a 40-inch Smart TV, there are many details to pay attention to, even if you have already decided on the size. The Internet mode offers users many options when using it. When watching movies and documentaries, viewers will be happy about a good Full HD resolution. This provides a nice viewing experience without any loss of quality.

The equipment with sufficient connections is also an important point when choosing a TV. After all, you often do not only want to watch TV, but also use the other functions of the Smart TV.

The 40-inch Smart TV from the test is a modern TV that fits nicely into medium-sized rooms and allows comfortable viewing for up to five meters away. This TV enjoyment is especially pleasant if you choose a device with a nice design. Although manufacturers focus primarily on the innovative technology of their devices, the look also leaves nothing to be desired. Glossy or matte black and silver gray are clearly in first place when it comes to TV design.

In addition to the color, the width of the frame or the shape of the stand also play a role. Or should the 40-inch Smart TV perhaps be mounted on the wall? Then you should pay more attention to the mounting parts.

Depending on which TV reception you use, the Smart TV must of course be adapted to the respective reception type. Generally, modern TVs have triple tuners, so you can use all three reception methods: Satellite, cable or DVB-T2. If you already have a receiver, you don’t necessarily need a 40-inch Smart TV with a built-in tuner. But for the future, it makes sense to order this modernized version now.

The modern 40-inch TV becomes a smart device thanks to its Internet capability. Its “intelligence” helps users go to the Internet and access videos directly here. However, before setting up the 40-inch smart TV, one should check how secure the Internet connection is.

In addition, it is worth taking a look at the menu navigation and automatic functions in this context. Do you have to reconnect the TV to the WiFi every time or does the connection remain intact? How is the operating system structured and how complicated is it to use?

40 Inch Smart TV Accessories

The 40-inch Smart TVs that were examined in the test now all have a preparation for pay TV. The corresponding slot is designed to accept the smartcard, which is simply inserted. Such a card is available from the respective pay TV broadcasters.

Storage media such as hard disks and USB sticks are used for saving pictures, movies and other data. Especially those users who take a lot of pictures or record videos themselves already have several USB storage media, which can be used in a variety of ways and also enable fast provisioning. Depending on individual habits, a USB storage device specifically for the Smart TV makes sense.

The 40-inch Smart TVs from the test are often the center of the evening and can be supplemented with many accessories. If you like to watch movies or follow sports tournaments, it is not only important to have a high quality picture, but also a realistic sound. There are various audio devices for home theater and also for watching sports events together. Surround sound offers a three-dimensional experience and is also suitable for larger rooms.

In smaller rooms, a 2.1 sound system is sufficient. Meanwhile, soundbars are popular, which are practical to install and reproduce the multi-channel sound very well.

You can use your 40-inch Smart TV mainly for linear TV or gradually get used to streaming. There are also other usage and connection options to choose from. The classic DVD and Blu-Ray players are not yet obsolete, but can be connected directly to the Smart TV. It is important that these additional devices are compatible with the TV and that the features match.

Among other things, it is worth checking the 3D capability. For perfect movie enjoyment in three dimensions, you also need the appropriate 3D glasses. Various technologies are available here, which should not be overlooked when choosing glasses.

If there are a lot of cables leading to the 40-inch Smart TV, you might need cable channels to avoid tripping hazards in the room. Unobtrusive cable channels also make the ambience look tidier and more attractive. In a rented apartment, you should make sure that these channels do not have to be screwed down.

The markets now offer more and more solutions that can be easily glued and removed without leaving any residue.

The remote control is already included in the scope of delivery of a 40-inch smart TV from the test. However, this can be replaced if necessary, for example via an additional keyboard or by the smartphone on which the required application is installed.

The handling of the standard remote control is basically unproblematic, but it can get a bit awkward especially when surfing and downloading. A Bluetooth keyboard is clearly the more convenient solution here. Such a TV keyboard often has a touchpad, which makes maneuvering in the menu easier.

You might need a WiFi repeater to boost the signal. Such a device ensures a better transmission to the Internet. Alternatively, you can also use a LAN cable for some 40-inch Smart TVs to establish a stable connection.

40 Inch Smart TV Alternatives

If you want to avoid buying a 40-inch Smart TV from the test, you can find out whether the existing TV is Internet-enabled and can be retrofitted. For this purpose, you need a compatible Smart TV Stick. Smart TV boxes are also offered as a substitute. To connect this additional part, the TV needs an HDMI input.

After that, you have access to the usual Internet applications like streaming and program media libraries. Compared to a real Smart TV, however, this retrofitted TV is not as high-quality, which can be seen in the native apps, for example. Depending on the quality, there can also be limitations in the picture display.

A simple TV without smart features is suitable as a kind of small alternative with fewer usage options. Nevertheless, it is still possible to record movies or import pictures from the smartphone and other devices.

Depending on the installed technology, even two-channel reception is possible. This means that you can watch one program while recording another. The stop function and replay cannot be compared with Time Shift, because time-shifted TV is not possible here. So you need a bit more patience and there are fewer functions available. Simple gaming without Internet access is still possible if the TV has the necessary connections.

Meanwhile, young people in particular watch TV on their notebooks. They save themselves the trouble of buying a TV, because on the PC they can access the Internet, media libraries and the extensive video offering at any time. Streaming, time-delayed transmission, saving and recording is child’s play on the notebook. On the other hand, it lacks the large display, because the PC’s small screen allows a maximum of two people to watch TV at the same time.
