What to look for when choosing the best 40 inch TV
Below are the main characteristics that you should pay attention to when buying a TV in order to get not just a good device, but also maximum functionality in the appropriate price category.
Screen resolution
Screen resolution is a value that denotes the ratio of the number of color dots, pixels that form an image, in the horizontal and vertical directions. The more pixels in the screen matrix, the clearer the reproduced image.
Today the highest resolution is 4K (4096x2160). The image on this TV is brighter and clearer than its predecessors UHD (3840 x 2160) and FuLL HD with a resolution of 1920 x 1080 pixels (1080p).
However, it is worth noting that UHD models are often advertised as 4K, and in order not to fall for the bait of marketers, it is worth double-checking the resolution.
When buying a 40-inch TV, FuLL HD and UHD resolutions are perfect for the average user, because the difference in the image on a small screen is almost unnoticeable, but the price is quite large.
Availability of HDR technology
Not many people know what HDR does, but this technology has a much stronger effect on image quality than simply increasing the resolution. HDR improves pixel quality, making images appear more realistic on screen. This happens due to the advanced backlighting of the screen, which releases brightness where it is needed (where the sun is shining), increasing contrast. TVs with this function have a brightness reserve several times higher than ordinary ones: up to 1,000–1,500 nits (standard HDR TVs have 300–400 nits).
In addition, the format helps to transmit colors previously unavailable for transmission on the screen, so the image becomes richer, more realistic and clearer, which causes a “wow” effect from the difference.
When asked whether this function is really so important, experts answer that this is the first significant leap in development after the transition from SD (Standard Definition) to HD television (High Definition TV).
Screen frequency
Screen refresh rate is an indicator showing how many times in one second the TV changes frames on the screen. It is measured in Hertz Hz.
High frequency ensures smooth images and clear storyboards of moving objects. That is, a person running on the screen will not “crumple”.
Important! The smoothness of the image is also affected by the fact that each frame is duplicated. This also reduces flicker, which negatively affects vision and well-being when watching TV.
The minimum acceptable value is 50-100 Hz, and 200 Hz is considered normal. Well, the higher the better, the image at 400 Hz is much more dynamic, but models with this parameter are much more expensive.
Note! A frame refresh rate that is too high, for example 1200 Hz, although it may be real if it is a product of a well-known brand, the human eye will not see it and will not be able to check it.
Backlight type
The type of backlight is how the LEDs are arranged, depending on which the characteristics of the matrix change. Today there are four types of backlight:
- Edge LED . LEDs are placed along the contour of the screen - a kind of luminous frame. These TVs are thin and economical and have a good viewing angle.
- Direct LED. LEDs are located along the entire plane of the screen. You can perform local dimming or adjust each diode separately, and the resulting image will become clearer and more contrasty.
- QLED . There is no “illuminating” block, and the illumination function is performed by quantum dots. Such screens convey colors that are more comfortable for the human eye. The image is bright and as natural as possible.
- OLED. Diodes are also used here, but they are coated with phosphor, a substance that glows when an electric pulse passes through. The viewing angle is small, but viewing is as comfortable as possible for the eyes.
The OLED screen type is recognized as the best today, but its cost is an order of magnitude higher than the alternatives. Therefore, here you should focus more on the budget.
Smart TV technology
Smart TV is a set of functions that I can use from a regular TV:
- search for information on the Internet;
- Watch movies online;
- view your feed on social networks;
- download applications for video streaming;
- make video calls.
But this technology has a significant drawback: you will have to control Smart using the remote control, and this is quite long and tedious. Therefore, this feature is not very popular among buyers. If there is no special need, then you can safely choose a model without Smart TV, saving a lot of money.
WiFi support
Wi-Fi-enabled TVs are devices with a built-in module that automatically finds and connects to a wireless Internet network. Using this TV, you can open presentations, use various applications (Skype, Viber, WhatsApp) and play online videos.
This is a very useful option, and if you don’t have one, you can purchase a wireless adapter that connects to the TV via HDMI or USB.
Number of built-in tuners
A tuner is a device that receives and decrypts digital television signals. It can be built directly into the TV, one or several, or individual.
Built-in tuners can process a television signal in one or more broadcast formats.
Most often, DVB-T/C tuners are built into TVs. If the specifications for the TV indicate DVB-T/C/S, then it will receive a digital signal from terrestrial, cable and satellite television.
But even if the purchased TV does not have a built-in tuner corresponding to the type of signal, you can always buy a separate one.
3D support
3D is a three-dimensional image that some TVs support. This technology developed with great strides, but soon stopped developing and large companies abandoned the production of such TVs.
They primarily justify this by saying that production costs were very high and sales were low. Consumers also complained of headaches and eye fatigue when watching, which undermined interest in the 3D format. The third reason is the lack of relevant content, although many disagree with this.
You can find a 40-inch TV with 3D support, but you should take into account that the prices for such a model will be higher.
Additional Information. A fairly large part of the population has such a visual feature as stereoblindness - the inability to perceive the depth of an object, its three-dimensional image. This manifests itself as unpleasant sensations and even headaches when watching 3D films. At the same time, in ordinary life, people may not complain about their vision.
