Shopping guide

If until a while ago 32-inch televisions were the basic reference in terms of size, today it is 40-inch televisions that have replaced this measure. A measure in which it is possible to implement 4K resolution, enjoying higher image quality and definition in any compatible content. So if you’re thinking of getting one of these new models, all you have to do is read our guide to buying the best 40-inch 4K TV and find out what you should look out for.


Image quality

To start making a comparison of 40-inch 4K televisions, it is necessary to talk about image quality. Something that may seem absurd, given that a 4K television uses a standard that should look more or less the same in all models, both in the most expensive and in the economic price. Nothing is further from reality.

A 4K television has a certain resolution, which is what establishes the standard. However, the rest of the parameters that the TV uses to mount those images are not set. We are talking about details such as contrast or brightness, that the higher they are, the better results they generate when viewing those images. The same happens with the brand’s own technologies, which give an extra quality to the image presented on the screen. These are issues that influence the final appearance of our programs on the television and also, in part, how much a specific 40-inch 4K television costs.

By the way, when it comes to getting the most out of this resolution, it is important to have quality elements but also to configure them properly. So if the product includes an assistant or similar with which to manage everything that 4K can do for us, much better.

Sound quality

As with the image, the sound quality is also variable. In this case, there are more notable differences in aspects such as power or the formats supported by the television. Regarding the first aspect, it is convenient that the model exceeds the 10 watts of output power that the usual televisions usually offer, even when they are products that are not going to be in especially large rooms.

As if that were not enough, it is essential that this television has compatibility with the audio formats used in the 4K system, such as Dolby Digital Plus or DTS HD. Although if it reaches Dolby True HD or even DTS HD Master Audio it will always be much better. And if this is not the case, we will always have the option of resorting to a sound bar or a Home Cinema, in case you need it.

With Smart TV or not

One of the aspects that is always part of our guides, as far as televisions are concerned, has to do with whether or not they have Smart TV functions. An aspect that, with regard to televisions of this size, is given by their characteristics, or rather by their resolution.

The issue stems from the fact that, at this level of resolution and size, it is practically impossible to find models that do not include these Smart TV functions. The question is logical, given that a user who bets on a resolution as high as this surely wants to have all the options at his fingertips. Therefore, removing the Smart TV function is not something “logical”. In any case, some lesser-known manufacturers do offer a product with these characteristics.

connection ports

Another important aspect of these televisions is to evaluate how many connection ports the equipment includes. We must think that to this television we surely want to connect not only our conventional antenna, but also a DVD player, a digital decoder or even a video game console. To connect all these devices it is obvious that we are going to need ports, so the more the better.

Among these ports we should have a good range of HDMI ports, no less than 3 and at least one of them capable of using the ARC system, with which to remotely control the TV when connecting certain devices. We must also have one or two USB ports, with which to connect pen drives to record or some other device. And if we also have other additional sockets, it will always be easier to have the product connected to everything we need.

Frequently asked questions

Q1: Is there a white 40-inch 4K TV?

There are several manufacturers that offer white 40-inch televisions in their catalogs. As an example we have Philips, which was one of the pioneers in “whitening” its televisions, to which companies such as Grundig, Samsung or Telefunken, to name a few, have been added shortly after. However, in case we want a 40-inch 4K TV in white, for now, to our knowledge, there is no manufacturer that has them in its catalog.

Q2: What is a 40-inch 4K frameless TV for?

Without having a specific utility, the idea of ​​frameless televisions is to offer better viewing sensations. In any case, it is important to know that the television still has a frame, since it is essential, but in exchange, it is covered with glass, to better hide its presence. In practice, this system offers a more elegant finish and a more interesting display, in line with what happens with phones with curved or infinity screens.

Q3: What is the minimum distance for a 40-inch 4K TV?

The distance to the screen for a 4K model is given by a relationship with its diagonal, this being equivalent to 1.3 times the diagonal of the television that we are evaluating. Thus, for a 40-inch or 101-centimeter diagonal 4K television, the distance would be approximately 1.3 meters. In any case, if we take a look around the net, we can find various other recommendations regarding the distance, so it’s all a matter of trying.

Q4: What to do if my 40-inch Samsung TV won’t turn on?

The first thing we must do is check that the television is really on and has not hung up, which can happen. To do this, we will press the buttons on the remote or we will leave the power button pressed, to see if there is a response. If there isn’t, we’ll unplug the TV from power and plug it back in a few seconds later to see if that resolves the issue.

This would be an important step also if the television does not turn on, having to check both the plug that goes to the wall and the one that goes to the television itself. Finally, if all this does not solve the problem, it will be advisable to change the TV plug, to see if it was a fault, as a last step before calling the technical service.

Q5: What are the dimensions of a 40-inch 4K TV?

A 40-inch diagonal 4K TV measures 101 centimeters across, along with a height of 49.8 centimeters and a width of 88.6 centimeters. However, these measurements belong exclusively to the visible part of the screen, and may vary considerably with respect to the final measurements of the television, which will include the frame and the base of the product.

Q6: What mount to use for 40 inch 4K TV?

Since each manufacturer has its own measurements, as far as establishing the distance between the screws in a VESA mount is concerned, it is difficult to indicate a specific type of support. Fortunately, current supports are very versatile and even more so for 40-inch televisions. So it is enough to see the VESA measurements of our television and check that they match those of the support that we have chosen.

Q7: Which 40-inch 4K TV to buy for a second home?

Given that it is a television that we are not going to use much and that it is surely in a place where we do not have WiFi or an Internet connection, the most reasonable thing would be to bet on an economic model that does not include Smart TV functions and that has a Full HD resolution.. Obviously, if this falls short and our budget allows it, we can always go up to the higher range, with Smart TV or with a 4K image.

Q8: Is it possible to find 40-inch 4K TVs without Smart TV?

Due to the characteristics of these models and the offer that manufacturers have, it is quite difficult to find a 40-inch television with 4K resolution that does not have a Smart TV included. However, there are some lesser known manufacturers that offer some of these products to consumers.

How to use a 40 inch 4k tv

When using a 40-inch 4K TV, there are simple functions, such as setting a channel, and more complex ones, such as accessing the Smart TV function, optimizing the image or playing content. Since the first ones are easy, we are going to focus on the second ones, offering you some guidelines so you don’t get lost when you have to face them.

tune the channels

One of the first processes carried out during the installation of a new television is to tune in to the DTT channels. However, there are many reasons why you may need a retune, ranging from a change in frequencies to the presence of new channels. To have an updated channel list, simply access the television settings from the remote control, access the television functions and here those that correspond to tuning. Options that vary by model, but shouldn’t be hard to find.

Accessing and using the Smart TV

Another advanced function of one of these devices is to access and use the Smart TV functions, which are common in 40-inch 4K televisions. Accessing them is usually easy, since most televisions include a button for direct access to the general menu or even to specific apps, such as Netflix or YouTube.

If this is not the case, simply access the TV functions, using the menu button, to see the different options and choose the Smart TV option. Once inside, we only have to move through the functions of the television and choose the app that suits us. And if you need an app that is not included, the TV will have a “store” where you can install whatever is necessary.

Connect your mobile

On 40-inch 4k televisions with Smart TV, it is possible to connect our mobile directly to it. A process that we can carry out directly by HDMI cable, if the phone is compatible, or through wireless options such as Bluetooth or WiFi. In this case, we can use the Miracast functions, which are usually the simplest. Anyway, check what your phone offers you to know which is the best option.

Record and play content

Current 40-inch 4k televisions include a USB port, where we can connect a USB device or an external hard drive to record our programs or load multimedia content. The use of this system is very easy, since it is enough to use the remote control keys to record content, which we can also program from the EPG. As for playback, it is easy to access it from the device’s functions, having the same options to advance or pause its progress. By the way, the process is identical to control the playback of files on the network, from your PC or another device.

Optimize the image

Optimizing the image is another of the necessary steps to take better advantage of the functions of our television. An especially more complex process in models with 4K resolution, which require more time to squeeze it. Fortunately, we have predefined profiles for certain broadcasts, such as sports, movies or concerts. In some 4K models, it is also possible to have an assistant, which helps us optimize the image according to our preferences. All these options are within our reach from the menu settings, on the remote control.
