All About TV Refresh RatesSeptember 13, 2016
Watching movies, series, and news have become a big part of millions of Filipino’s lives. In this regard, getting an affordable TV in the Philippines is a must for most families. Purchasing and owning a television entails plenty of things. You have to be knowledgeable about certain factors if you want to get a TV. One of the basic information that you will be required to know is TV refresh rates.
What is a TV refresh rate?
Refresh rates are known as the count of frames per second that a television is capable of displaying and Hertz is a unit of frequency used in televisions; it is equal to 1/second. If your TV’s refresh rate is 60Hz, then your television can exhibit about the same number of images per second in its screen. The common refresh rates are 60Hz, 120Hz, and 240Hz.
- 60Hz – affordable televisions usually have a refresh rate of 60Hz, which is still pretty good. These TVs have the ability to show 24fps and 30fps clips at 60 times per second. Since it is impossible to distribute 24fps in 60Hz, blurring might occur. This is due to a technique called “pulldown,” wherein some frames are displayed several times. This is used especially for 24fps displays wherein some frames are shown two or three times. Meanwhile, the 30fps has no problem in displaying 2 frames per second at ease, showing clear quality displays. Most displays for video game consoles show about 60 frames per second.
- 120Hz – just imagine that a 60Hz display is improved. It can sync well with a 24fps and 30fps displays. When it comes to the former, a solo frame is shown 5 times before shifting to the next frame. On the other hand, when it comes to 30fps, frames are displayed at 4 times before moving on to the next one. Because of this, watching TV with this refresh rate will be undoubtedly nice and flawless.
- 240Hz – the 240Hz produces the best display, especially compared to the other two displays. It can also display more frames than the others and it projects crispier displays. In addition, images are less likely to be blurry when it comes to TVs with a refresh rate of 240Hz.
Simply put, a high refresh rate means that images and videos will be displayed in better quality. With the innovations and advancements these days, televisions will further evolve and improve to improve people’s viewing experience.
Is it the same with LCD, LED, and Plasma display?
The answer to this question is “no.” LCD or LED maintain an image for the overall frame length, while plasma uses short pulses to display a picture caused by the greatness of colors. A plasma TV produces greater display compared to LCDs and LEDs. However, LCD televisions are more compact and thin. Despite boasting high refresh rates, LCD and LED TVs are arguably inferior when it comes to the quality of display compared to plasma televisions.
Knowing about refresh rates is important if you want to purchase a TV. However, it is not the only aspect of televisions that you should consider or learn about. Choose a television that will suit your liking and needs.
