What do tv hertz mean




















When you're watching a talk show, you won't notice the difference. A Hz TV is especially suitable when it comes to fast moving images, like soccer or tennis matches and races or action movies. Each quick action is displayed smoothly. As a result, a Hz TV will display the fast games of these consoles even more smoothly. Older gaming consoles don't support a Hz refresh rate. If you play with these consoles, it doesn't matter if you have a 50Hz or Hz television.

TV brands always have their own names and calculations for refresh rates. That's why, for every TV, we communicate a general rating that's equal for every device. This is called the native Hertz rating. This way, you can easily compare TVs made by different brands. The first is filming the show, and the second is displaying it. When a TV show or movie is filmed, a camera speed of 24 or 30 frames a second is used depending on the camera.

There are some variations between camera makers, but in general 24 or 30 frames per second is about right. As you know, technophiles love abbreviations, so 24 frames per second is usually shortened to 24fps. Every second of filming contains 24 or 30 snap-shots that when viewed in succession give the illusion of movement.

It's the same process that made your childhood flipbooks work or for those that are older: the nickelodeon machines. Now that we have the image recorded, we have to play it on a television screen. To do that, you must understand the second part of the television process: displaying the image. The speed at which a television can switch between one frame and another in one second is called the "refresh rate" and is measured by "hertz. Congratulations, you have a very expensive digital photo frame.

If you want to watch a movie, which is shot in 24fps, then your TV has to at least be capable of displaying 24 images per second. We also can say, it must be at least 24 hertz. Especially with competitive PC gaming, titles often excurse well above 60fps, and many modern gaming monitors will offer Hz or even Hz refresh rates in order to capture the best gaming experience. While a Hz TV isn't necessarily the perfect display to pair with a PC game, it's going to handle things much better than a 60 Hz option.

I wish I could say it was as simple as checking a spec sheet, but refresh rates are often represented in a confusing manner. For at least the last decade, TV manufacturers have implemented so-called " motion interpolation ," sometimes called motion smoothing, motion assistance, or the " soap opera effect. Keep in mind that this kind of interpolation, while available in some form on almost every TV, doesn't have anything to do with whether the TV is a 60 Hz or a Hz model.

And while some types of content can certainly benefit from these modes, they aren't the same thing as a hardware-level refresh rate. Manufacturers often list refresh rates on TV product pages, but you should always cross-reference with professional reviews and sites like Amazon or Best Buy. However, there are ways to find out a TV's true refresh rate. Spec sheets on sites like Amazon and Best Buy often list real refresh rates, and often times manufacturers' product pages are reliable too.

But if a manufacturer lists an "effective" refresh rate, the TV's actual native refresh rate is usually half of the advertised effective rate, and other factors—like smoothing and backlight scanning—are sometimes used to multiply refresh rates into higher and higher numbers, such as " Hz. Ultimately, your best bet is to check out unbiased sources like enthusiast forums and professional reviews— here's a good place to start. We'll help you find the best stuff and love the stuff you own.

When a movie is running at 24 frames per second, for example, but the refresh rate is higher, the TV may insert extra frames to fill the gaps. This can be relatively straightforward when the refresh rate is divisible by the frame rate, as the TV can show multiples of the same frame.

A Hz refresh rate showing fps content, for example, can display each frame five times. But with a Hz refresh rate and fps footage, you end up showing an uneven number of frames, which can cause a juddering, shaky effect for some viewers. Some TVs use motion smoothing or frame interpolation. They generate and insert new frames by processing and combining the surrounding frames. At least with movies, the frame rate is fixed.

With games, the frame rate can fluctuate wildly. This solution to the difference between frame rate and refresh rate has been around in PC gaming for many years.

This is important for console gamers playing on TVs. Some of the latest smartphone and tablet displays support some kind of VRR. Changing the refresh rate like this reduces the risk of stutter or other unwelcome effects, and it can also reduce power consumption.
