Did she go out in lingerie on the street? look at the picture that went viral – Bajo Palabra



México.-You come to a store and you go to the electronics section, ready to buy tv that will give you hours of entertainment. You do not know which model you want to buy, but you're sure of two things: you want a big screen and have a good picture quality.

Then a man in a black suit comes up to you and says: This TV has OLED panel, 4K resolution, HDR mode, loud sound system and blah, blah, blah …

It is thus easy to get lost between names of brands, models and technical specifications. Therefore, we compile a list of things to consider before paying your wallet or sweeping the credit card to purchase a new TV. Because the important thing here is to not buy the best screen by everyone, but the one that best suits your needs and pockets.

Size matters

Let's Be Clear In addition to technology, the first thing you should do is consider the space available. If the place you are going to install is the TV small, with a very large screen you will not get a good point of view. On the contrary, if the room is very big and the TV is small, you will miss the details.

In the following table you will find the connection between different sizes of screens (in inches) and the recommended distance to view:

TV size Recommended distance
26 "1.0m – 1.7m
32 "1.2 m – 2.0 m
37 "1.4m – 2.4m
40 "1.5m – 2.5m
42 "1.6 m – 2.7 m
46 "1.7m – 2.9m
50 "1.9m – 3.2m
52 "2.0m – 3.3m
55 "2.1m – 3.5m
58 "2.2m – 3.7m
65 "2.5m – 4.1m
70 "2.7m – 4.5m

Without a doubt, one of the most important aspects is to consider screen technology. LCD panels dominated the market for a long time, but at present, very few televisions continue to use this technology.

In fact, there are two predominant trends. On the one hand, we have OLED screens, which get cleaner black and a better level of contrast and colors. This is because the pixels in OLED panels emit light instantly, unlike LCDs. Its main problem is the decomposition of light emitters, which is why this type of monitor is not recommended for prolonged use, such as on static display monitors.

On the other hand, we have the QLED screens: a technology developed by Samsung under the name Quantum Dot (consequently the letter "Q"). QLED TVs use LCD panels and LED backlighting, but the on-screen pixel activation is done individually, which enhances the contrast and provides an image quality comparable to that of OLED screens. The disadvantage of this technology is that it is used only by Samsung, and its cost is higher than the average.

Let's talk about resolution

The resolution is the number of pixels that can be displayed on the screen and measured horizontally and vertically. The higher the number of pixels on the screen, the higher the resolution. These are some of the formats:

HD (720p): The pictures ended up having a 4: 3 aspect ratio to make the jump to 16: 9. It offers 1 280 x 720 pixels. Current TV models no longer use this format, so it is considered outdated for this kind of screens.

Full HD (1080p): It is the current standard for high resolution and offers images of 1 920 x 1,080 pixels.

Ultra Full HD (4K): If we consider 1000 pixels equal to 1K, then 4K resolution refers to 4000 pixels in horizontal mode. Thus, 4K or Full HD TV offers 4 966 x 2160 pixels, that is, almost four times full HD format.

While the current trend is against 4K, the truth is that you can only benefit from your TV if the content you play is also in that format. 4K is the future, but it's a future that will still take a long time to come.

If your pocket allows, buy a 4K screen; but if it's not your budget, do not worry, a full HD will do the job for a few years.

HDR and Dolby Vision

But the resolution is not everything. TVs have long begun to include the HDR (High Dynamic Range) legend in their boxes, which refers to high-dynamic range technology. This allows for a better light range between lighter and darker areas in an image, ie whiter white and black more black. What is this for? To get a picture with better light and color, which gives us a more natural result.

As usual in technology, the HDR standard is not the only one in the industry. There is an option called Dolby Vision, which requires more power in the hardware compared with HDR, but that produces a similar result in image quality. The difference is that it's a proprietary technology from Dolby Laboratories (HDR10 is an open standard), so there are only some brands that use it.

Importance of a SmartTV

Smart TVs are characterized by an operating system integrating with applications like Netflix, YouTube, Spotify, etc. Some brands develop their own platforms and others use third party systems: LG has WebOS, Samsung has Tizen and Sony uses Google's Android TV.

In this case, it's important to consider the brand on your TV, as most products of smaller brands take too long to update their operating systems, or never do it. In such cases, it is better to buy a device such as Chromecast, Apple TV, or Roku, which is responsible for keeping their platforms up to date.

The myth of the sound

The struggle for increasingly narrow televisions has led manufacturers to put away the sound. If you're looking for a quality experience, you can buy your own audio system and connect it to your screen. But if you want to watch comics and movies like all deadly, it's likely that the system that already integrates your TV is enough.
