What is the difference between hz on lcd tvs

These images can be jarring to the viewer, a phenomenon known as motion blur. With fast-moving video such as sports and console gaming, the effect can be more pronounced, simply because objects on the screen may have moved more between images.

A TV running at Hz rather than 60Hz cuts the time between each fresh image, reducing motion blur. Because a 60Hz display shows 30 frames per second, the TV has to use a workaround to rectify the disparity. This workaround means that in some cases the content of the screen will be made up of two separate frames from the original movie, creating a blurry image known as judder.

Not all viewers like the effects of removing judder from movies. It can make the picture look like it was shot on video rather than film, which can change the visual effect. Ironically, some viewers may also find that the smoother picture that comes with Hz looks less realistic. As a very rough rule, sports and game lovers may find the benefits of Hz outweigh the drawbacks, while movie lovers may find the opposite holds true. Wherever possible, spend some time auditioning a potential purchase with the type of video content you watch most often.

Most other listings are extrapolated. Just keep in mind that regardless of the TV's refresh rate, it can't create more information than the source is displaying.

This is a key detail in determining whether or not you need a Hz TV, or can settle for a 60 Hz option. If you just want the most high tech TV money can buy, a Hz option is never going to do a worse job than a 60 Hz option. Sure, it isn't twice as good just because it's twice as fast, but logically it won't ever miss any source information that a 60 Hz variant wouldn't. In the early 20th century, cinema experts decided that 24 frames per second—also called 24fps or 24p—was the minimum necessary amount of frames to convince human beings that they were seeing moving pictures.

Far from outdated, many of today's Blu-ray discs still default to 24 frames per second to preserve the filmic aesthetic you'll get at the movies. To combat this, many modern 60 Hz TVs use a telecine technique called " pulldown," where frames are doubled in alternating sequences in order to "meet up" with the locked 60 Hz display speed. Unfortunately, pulldown usually results in a motion artifact called "judder," where in-motion sequences during playback have a stuttering or skipping effect.

While many modern 60 Hz TVs do pulldown so successfully that you'll never notice the tiny amount of judder, you can save yourself the trouble by purchasing a Hz TV instead. 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. The refresh rate dictates the maximum frame rate that can be accomplished by your monitor. So if you have a Hz television, then it can refresh times per second. But, your can never exceed your refresh rate in terms of fps. The refresh rate is its overall capacity. Or if you have a TV capable of 60Hz, it will still try to run films at their original frames per second, which is typically 24fps.

Now, when watching TV on a television with a higher refresh rate than the standard 24fps, you may end up with something called motion interpolation, or motion smoothing. Basically, what this does is add additional frames in-between the current frame rate that the TV show or film was filmed in. As most films are made in 24fps, if you were to watch this on a Hz television, it would add an additional 4 frames in-between the ones that were filmed. Whilst the process is meant to help smooth the picture and minimize any motion blur, it can end up making things look realistic.

One exception was The Hobbit , which was actually filmed in a faster 48fps. It ended up being widely viewed in 24fps, as it was decided that it was a better viewing experience after some initial testing. In most cases, a 60Hz television is going to be absolutely fine for your purpose. Many of the smart TVs being released today are going to be 60Hz refresh rate. This is just because television networks broadcast at a 50Hz limit in Europe. This is the same case for higher refresh rates too — in the UK, you might see a TV advertised as Hz, but this can play video games at a higher Hz refresh rate just fine.

Most televisions that are Hz will have the option for you to reduce the rate back down to 30 or 60Hz if you want to.
