What is the best TV refresh rate: what is the refresh rate, what is affected by the refresh rate.

Television is one of the most popular entertainment, and in recent years it has appeared in almost every home. Modern technology continues to evolve, so the latest TV models are distinguished by an increasing number of features and improved image quality. But how to choose the perfect TV? What should I look for?

An important role is played by the indicator of the refresh rate of the screen. What is it and what indicator will be an evidence of an excellent image?

What is the screen refresh rate?

All modern TVs work so that frames are constantly changing on their screens. This principle is valid not only for televisions, but also for laptops, as well as other devices that have a display.

In order for the viewing to not cause discomfort, the refresh rate of the screen should be quite high.

IMPORTANT! In addition, doctors note that with a slow-motion image display, a person has various unpleasant symptoms - for example, a constant headache. Many people of the older generation who had to work on old models of computers, where the picture changed for a long time and often on the screen still had “traces” of the past image, when a new one appeared, they recall that spending a lot of time at the display was just impossible. A headache appeared after several hours of such pastime.

What is more important update frequency?

What is affected by the screen refresh rate

This indicator is directly related to image quality. The higher the frequency, the clearer and more pleasant the picture will be.

This dependence can be easily traced using a good example. Surely everyone remembers the old TVs, which are still standing with someone in the country or at grandmothers. The screen refresh rate for such devices is 50 Hz. Pay attention to the fuzzy image and some "blurry" picture. Now compare with the new models, where the frequency is several times greater - the difference is obvious.

Thus, you should definitely pay attention to this parameter when choosing a TV receiver.

What screen frequency should a good TV have

Now let’s dwell on which indicator is the key to good image quality.

You already understood that frequency is measured in hertz. The number indicated in the characteristics of the device shows how many frames it can show in a second! Logically, the higher the number, the better for the TV.

Currently, digital television is spreading more and more. Some sellers may assure you that a 100 Hz readout will be ideal for such a signal, but this is not entirely true.

IMPORTANT! The best option is the TV with a screen frequency of at least 200 Hz.

Scan and screen type

In order to better understand the principle of frame change and understand the frequency parameter, you should know the characteristics of those technologies that are currently used in the manufacture of televisions.

1. LCDs are one of the very first liquid crystal screens, which are now the most budget ones. After their creation, a huge number of other, more modern technologies have appeared that significantly surpass them in quality. The frequency of the screen, which is suitable for these monitors, is about 100 Hz.
2. LED is the next generation of displays, which nevertheless can also be considered obsolete. They differ in the presence of special diodes that provide the screen with backlight. There are several types of such monitors, in each of which the diodes are located in different places, which significantly affects the image quality. The price also depends on this.
3. Plasma models provide the ability to watch TV with an even sharper picture, but their disadvantage in the short period of operation - after a few years the panel burns out, which affects image.
4. OLED - at the moment it is the most advanced technology that does not require additional illumination.

Along with the advent of the digital signal, the screen frequency increased significantly, which became a real revolution in the field of TV. This allowed us to get rid of flicker, and in the future to achieve the greatest smoothness of the image with the help of additional frames.

What does the TV market offer today

Now the technology has improved so much that modern manufacturers offer customers such televisions, the sweep of which ranges from 600 to 800 Hz. This means that such TV receivers provide unsurpassed image quality, although this requires some additional conditions.

IMPORTANT! Please note that the clarity of the picture, although it depends on the scan, but still there are other factors that significantly affect it. This can be a signal level, screen resolution, or other parameters.

Now you know what the screen refresh rate is, why it is important to pay attention to this indicator when choosing TV and how many hertz will provide you with a magnificent image for the most comfortable viewing of your favorite shows and TV shows.
