Refresh rate refers to how many frames your screen can display per second, while frame rate is how many frames the video source can display per second.
All movies and TV shows are made of a series of still images or frames. These frames are shown in quick succession to give the appearance of motion. Videos with higher frame rates usually have smoother motion, as long as your TV has an equal or higher refresh rate.
Most TV shows in the US are filmed at 30 frames per second fps , while most movies are filmed at 24 fps. So, you only need a TV with a refresh rate of 30Hz to watch most content. However, getting a TV with a faster refresh rate is a good idea for a few reasons. While they will both look identical when watching TV shows filmed at 30fps, TVs with a faster refresh rate are generally better at handling motion when watching movies filmed at 24fps.
That same video will look identical on a Hz TV since the TV will just display each frame four times and play them a quarter as long. However, the problem comes when you want to watch a movie on a 60Hz TV.
This is because most movies are shot at 24 fps, which is not a good divisible of To do this, the TV will display one frame twice and then the next frame three times. And since that makes for the majority of content, many find Hz unnecessary for TVs. Alternatively, an exception to this would be watching native 24 FPS content from a media source such as Blu-ray. Think about it: because the source feeds the display 24 frames per second, a 60Hz TV has to alternate between adding 3 and 2 frames in-between those 24 FPS in order to produce the picture.
Since refreshes per second can allocate a smooth ratio for 24fps content, Hz TVs can handle native 24fps content without judder. Complicated mathematics aside, whether you need a Hz TV or not really comes down to content. You might think, "I definitely want to be able to watch native 24p content! No way am I getting a 60 Hz TV," but it's less of a discrepancy than it seems at first glance. While you'll want a Hz TV to enjoy "filmic" Blu-ray content with the least amount of fuss, most other kinds of content work with either.
Broadcast television in the U. Other than a few exceptions, getting 24p playback from streaming providers like Netflix isn't possible. Almost every streaming service adjusts resolution and buffering to play smoothly at 60p, making a 60 Hz TV perfectly capable of good playback.
If you enjoy console gaming at home, you'll be glad to know a 60 Hz TV is, again, just fine. Even the newest consoles—namely the PS4 and Xbox One—only support up to 60fps right now, and likely will going forward. Where this differs is in PC gaming. 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.
This works because motion blur is caused in part by the pixels of the TV screen not switching color quickly enough. With TVs, they use a process called sample and hold , resulting in the pixels holding on to their color for a fixed period.
One solution to this problem is to make the screen black in-between frames, making the color transition of the pixels much sharper and cleaner.
You just need to know that some people think it can be pretty effective. Many people get confused between television refresh rates and the motion blur that they see on screen. Progressive video recorded at 60 fps will look smoother than that recorded at 30 fps because it captures more detail in the movement.
Motion blur on a TV occurs when the image appears blurry when there is quick movement on the screen. It is a misunderstood issue because the motion blur that you see can be caused by several different factors:.
All of these can contribute to what people see as motion blur. As you can see, none of these are directly caused by a low refresh rate. While higher refresh rates can help to make these techniques more effective, they are just a small part of the whole problem of TV motion blur reduction.
Motion blur on a TV can be very annoying. However, some people are more sensitive to it than others. If you like delving into the menu and changing a few settings, you may improve performance in some circumstances. If you want some quick and simple answers to common questions, here are a few frequently asked questions about TV refresh rates. It may also show 24 Hz movies with smoother motion and reduce motion blur for some people. The difference in performance between 60 Hz and Hz is relatively small.
In some circumstances, viewers may notice smoother motion on the screen, but it will make little difference for most people. It can be challenging to know the native refresh rate of your TV because many manufacturers quote elevated numbers. The native refresh rate can only be 60 or Hz. Another way is to check quality reviews for that TV, and that should quote the actual number.
Otherwise, it will unlikely make much difference. A 60 Hz TV can only display 60 frames per second. A 60 Hz TV can use image processing to interpolate 30 fps video up to 60 fps — but the TV cannot display more than 60 frames every second.
