The Best Smart TV 40 Inch: Our Choices

Guide: Questions you should ask yourself before buying a 40-inch Smart TV

What is a 40-inch Smart TV and who is it suitable for?

A Smart TV is an all-rounder that allows you to stream videos, series, films and music, but also to surf the Internet, by connecting it to the Internet. Basically, a Smart TV is suitable for all those who want to use their TV set for something more than just watching TV.

Smart TVs are often also called "hybrid TVs"!

Smart TVs, on the other hand, have several advantages over conventional TVs. Probably the biggest difference is the number of different interfaces. "Smart TVs can be seen as a combination of TV and PC, as they often also have connections such as USB, HDMI, network or for memory cards. Most smart TVs also have powerful processors that offer the opportunity to run a wide range of applications.

Probably the most important interface is the connection to the internet, which is either via a network connection or wirelessly via WLAN. This interface enables the TV to call up functions, such as streaming films, series or videos, that were previously only possible on a computer. If the TV also has an integrated camera, video telephony via apps such as Skype is also possible.

What does a 40-inch Smart TV cost?

The price of the various 40-inch Smart TVs varies greatly. Cheaper models are available for as little as €250, while high-class models can cost up to €750. Depending on the brand, functions and screen resolution, the cost varies.

If you opt for features such as voice control, recording function, 3D or an integrated hard drive, the price of the TV set increases. In addition, Full HD sets are much more affordable than UHD 4K (Ultra HD) sets.

Screen resolution price range
Full HD 250 - 400€
UHD 4K 450 - 700€

When buying, it is particularly important to pay attention to the functions you need. You should also compare the prices of different manufacturers, as they can vary greatly.

Which design is ideal for me?

When it comes to design, the colour of the TV, the frame and the difference between flat screen and curved screen play a special role.

The most common models are available in black, silver or white. While the somewhat cheaper models usually have a wider frame, the more expensive models usually have a frameless design that looks modern and classy.

In contrast to the classic TV screen, the curved screen has several advantages.

So-called "curved screens" are not only available for gaming or at work, but now also for entertainment purposes. These can score points not only with their elegant design, but also with their flowing screen curvature. In addition, such TV sets are easier on the eyes and allow a panoramic view.

What alternatives are there to a Smart TV with 40 inches?

If you do not currently own a Smart TV and are not considering buying one, but would still like to use some of the functions of a Smart TV set, you can also consider these following alternatives.

The most common options are the Amazon Fire TV Stick or Cube, the Google Chromecast and the Apple TV. These are simply connected to the TV via USB and connected to the internet via WLAN.

Alternative Price
Amazon Fire TV Stick/Cube 60€/120€
Google Chromecast 40€
Apple TV 160€

Among these alternatives, the Google Chromecast delivers the best "Smart TV experience". While the function of the other two devices is limited to streaming services, the Google Chromecast also allows you to surf the Internet through the integrated Chrome browser.

Decision: What types of 40 inch Smart TVs are there and which one is right for you?

Basically, most 40-inch Smart TVs have either Full HD or Ultra HD screen quality. The resolution of the TV screen differs. In the following, we will explain these two types and go into the advantages and disadvantages.

What does a Full HD Smart TV with 40 inches offer and what are the advantages and disadvantages?

The term Full HD (Full High Definition) refers to a TV screen with a resolution of 1920 x 1080 pixels. Synonyms for this include True HD or HD ready.

The following table lists the advantages and disadvantages of a Full HD Smart TV:

  • Usually cheaper than UHD TVs
  • Recording Full HD movies requires less storage space
  • Lower resolution than UHD TV
  • Picture can be blurrier than UHD TV

What does an Ultra HD Smart TV with 40 inches offer and what are the advantages and disadvantages?

Ultra HD TV (Ultra High Definition Television) refers to the quality of TV screens with a resolution of 3840 x 2160 pixels. Especially in the future, more and more picture material will be offered in 4K resolution.

In the following table we show you the advantages and disadvantages of an Ultra HD Smart TV:

  • Very high resolution due to high pixel count
  • Investment for the future
  • Recommended if sitting distance to the TV is rather small
  • Currently few UHD movies and series
  • Human eye can't tell the difference between resolution
  • UHD usually only makes sense with larger TV models

If the sharpness and resolution of your Smart TV is particularly important to you, you should go for the UHD version.

Buying criteria: These are the factors you can use to compare and evaluate 40-inch Smart TVs

In the following, we will show you which aspects you can use to decide between the many possible Smart TVs.

The criteria you can use to compare 40-inch Smart TVs include:

In the following paragraphs, we will explain what is important in each of the criteria.

Screen resolution

Screen resolution is clearly one of the most important buying criteria you need to consider. Simply put, screen resolution describes the number of pixels that are displayed on the screen. Most 40-inch Smart TVs are either Full HD or Ultra HD devices.

labelling resolution (pixels)
Full HD - 1080p 1920 x 1080 pixel
Ultra HD - 2160p 3840 x 2160 pixel

Full HD is now one of the standards for displays of all kinds. As shown in the table above, Full HD Smart TVs display a maximum of 1920 pixels horizontally and 1080 pixels vertically. While UHD Smart TVs can display a maximum of 3840 pixels horizontally and 2160 pixels vertically.

Basically, buying a UHD TV set with 40 inches makes sense in most cases. In addition, it can be assumed that the closer you sit to the Smart TV, the more likely you are to go for a 4K device.

Operating system

Roughly speaking, the operating system is the interface or software on the Smart TV, comparable to Windows 10 or Apple IOS on a computer. Different manufacturers have their own operating systems, as the following table shows:

TV manufacturer Operating system
Samsung Tizen
Panasonic My Home Screen
Philipps, Sony, etc. AndroidTV

The operating systems usually only differ in terms of the interface, the design and the app store. In addition, most operating systems offer the same functions, only in terms of apps or recording options there are deviations.

To choose your personal favourite, you can go directly to your nearest electronics retailer and try out and look at the various systems. There are also many pictures and videos of the various operating systems and interfaces on the internet, so you can form a good initial opinion.

Connections and additional functions

A special feature of Smart TVs is the large number of connections and additional functions, but which ones do I really need? This list shows you the most common connections on a 40-inch Smart TV:

  • USB connection
  • HDMI connection
  • Ethernet connection for the Internet
  • Headphone jack
  • Audio output/input
  • CI+ slot for HD+ customers
  • WLAN function
  • Bluetooth function

Your 40-inch Smart TV should have at least two HDMI connections, a USB connection and either an Ethernet connection or the WLAN function. If you want to connect Bluetooth headphones or a Bluetooth keyboard to your TV, make sure that your device has Bluetooth.

If you want to connect a game console, your PC, a projector or your home cinema to the TV set, make sure that you have at least two HDMI connections so that you don't have to keep plugging them in. To connect your smartphone or camera to the 40-inch Smart TV, you can use the USB ports.

Basically, when it comes to connections, not only "the more, the better" applies, but also "the more up-to-date, the better". To enable faster data transfer, make sure that the HDMI connections support HDMI 2.0 and the USB connections support USB 3.0.

Many 40-inch Smart TVs offer additional functions such as voice or gesture control, parental controls, USB recording or surround sound. Before buying, consider whether it is worth paying a slightly higher price for these additional functions. Many of these are usually just "gimmicks" that you don't really need.

Energy efficiency class

The energy efficiency classes provide information about the energy efficiency of technical devices, buildings or machines. In the area of TV sets, the classes range from A++ (very high efficiency) to E (low efficiency). In addition, further information such as the power consumption, the power in watts and the screen diagonal must be stated on the label.

However, it should be noted that the energy efficiency class does not provide information about the actual power consumption of the TV set. It is more important to focus on the power consumption in kilowatt hours per year (kWh/annum) and compare this figure with other Smart TVs. This data is usually also noted on the energy label.

Smart TV 40-3

Since 2013, manufacturers have had to provide information on energy efficiency. Smart TVs are classified from A++ to E. Nevertheless, you should also pay attention to the actual electricity consumption per year.

So if you are looking for a 40-inch Smart TV and don't want your energy costs to explode, compare the electricity consumption per year of the different models. This serves as a very good guide, especially for devices with the same screen diagonal.


The processor ensures that a Smart TV is not just a normal TV set. That's why you should keep a close eye on the processor when making your choice. The processor ensures the smooth functioning of the operating system.

The processor is the heart of a Smart TV.

Most 40 inch Smart TVs have a Quad Core processor or a Quad Core Plus processor. To be sure that your Smart TV's processor is powerful, you can also check various magazines on the Internet, as they constantly conduct performance tests on processors.

Reception mode

When it comes to the reception type of Smart TVs, a basic distinction is made between the following options: DVB-C (cable), DVB-S (satellite) or DVB-T2 (terrestrial). DVB-T has no longer existed since around 2016 and has been replaced by its successor DVB-T2.

When selecting the reception, you should pay particular attention to whether your previous connection to the TV set is suitable. You should also consider whether you want to watch content in UHD, so you should choose either DVB-S2, DVB-T2 or DVB-C with a connected receiver.

If you want to be on the safe side, you can opt for a triple tuner TV, which supports all three types of reception.

Facts worth knowing about 40-inch Smart TVs

How do I connect my 40-inch Smart TV to the Internet?

A connection to the Internet is necessary to use most of the functions of a Smart TV. How you connect to the Internet depends on your TV set. Does it have Wi-Fi or a network connection?

If your 40-inch Smart TV has a network connection but not Wi-Fi, you must connect your TV to the line using an Ethernet cable and then select the desired network in the settings. If you have a wireless connection, simply select your Wi-Fi in the settings, enter the password and you are connected to the Internet.

If you still have any problems connecting, first check to see if your software on the TV has any updates. If this is not the case, you can check the homepage of most manufacturers to find out where the problem is.

How do I install an app on my 40-inch Smart TV?

Basically, installing and downloading an app is a piece of cake. First, make sure that your TV is connected to the Internet. Then you have to go to the App Store of your Smart TV. For Samsung and LG devices, this works via the Home button or the "Smart Hub" button, and for Panasonic devices via the "Viera Cast" button.

Then you only have to select the desired app with the arrow keys and confirm with the Enter key. After you have pressed the "Install" button, you can open and use the app. To delete an app, simply click on the app and then on "Remove".

Which Smart TV apps should I definitely use on my 40 inch Smart TV?

To be able to use all the functions of the Smart TV, it is advisable to install various apps from the App Store. I will now list some interesting apps that you should definitely take a look at.

To easily stream your favourite series and films on the Smart TV, you need the app of a streaming provider, e.g. Netflix, Amazon Prime or Sky Go. To extend this, you can download the YouTube and Spotify app.

Gaming apps turn your Smart TV into a gaming console.

The app "Zattoo" allows you to watch TV wirelessly even without satellite. For a monthly fee, you can stream over 100 different TV channels. About 70 channels are even free. If you want to use social networks on your Smart TV, you can also install apps like Facebook, Twitter or Skype.

How do I connect a PC/beamer/PS4 or XBOX to my 40-inch Smart TV?

In most cases, these devices are connected via HDMI cable. However, your device may already have Bluetooth and you simply need to pair it in the settings.

To connect your PC, projector or gaming device to the TV, a conventional HDMI cable costing between €5 and €10 is sufficient. Older devices, such as home theatres, may be connected via a VGA connection.

How do I connect my smartphone to the 40-inch Smart TV?

If you want to play the content of your smartphone on your TV set, you can do this by connecting it directly. With your Android smartphone, you can either use the "Screen Mirroring" app. To do this, select the desired TV on your mobile phone, enter the security code and the screen of your smartphone will be displayed on the TV.

Alternatively, there is also an app called Miracast, which works in the same way and connects your mobile phone to the TV via WLAN. There is also the option of connecting your smartphone via USB, but this is not as convenient as using an app.

How can I record programmes and films on my 40-inch Smart TV?

You can choose whether you want to save your films and series either directly on the TV, on an integrated hard drive or on an external hard drive / USB stick. The slightly more expensive 40 inch Smart TVs usually have an internal storage space, otherwise you have to take the variant with the USB stick.

A 500 GB hard disk is sufficient for about 50 films in HD. After you have formatted the hard disk, you can start recording by clicking the "Record" button on the remote control. To stop recording, simply click the "Stop" button.

How do I clean my 40 inch Smart TV?

To clean your 40-inch Smart TV, it is recommended that you use a special TV cleaning product. You can get these either at your nearest electronics shop or at online shops and they usually cost between €5 and €10.

Use microfibre cloths to avoid leaving scratches. Do not use harsh cleaning agents, as this could damage the screen. Switch off the TV before cleaning and, if possible, unplug it. After wet cleaning, wipe the TV dry.

What is the optimum sitting distance from a 40-inch Smart TV?

Basically, you can calculate the optimal sitting distance from the TV set using a rule of thumb. This is: screen diagonal in cm x 2.5 = distance in cm. However, other factors such as your own eyesight, the resolution of the set and your own perception play a major role.

Generally speaking, the higher the resolution of the TV set, the shorter the necessary distance to the 40 inch Smart TV. This is because the further you sit from the TV, the less you notice the poor and blurred resolution. So if you have a Full HD set, you should sit further away than if you have a UHD set.

With a 40-inch Smart TV, i.e. a screen diagonal of 101.6 centimetres, the optimum sitting distance, regardless of vision and screen resolution, is 254 centimetres, i.e. approx. 2.5 metres.
