It becomes more obvious when playing video games or watching fast-paced sports games, including any kind of content where the camera has to quickly pan horizontally. If you have a TV with a Hz refresh rate or higher, then you will see a significant reduction of these effects. Are you thinking of upgrading your existing TV and splurging on one with a higher refresh rate? If you are a sports or action fan, plus you love playing games on your HDTV, then every dollar you spend on it is worthwhile.
Bear in mind, if you watching it through traditional terrestrial network you might need an outfoor HDTV antenna too. But even if you only occasionally watch fast-paced movies or shows, the investment might still make sense, so long as you master setting the appropriate refresh rate based on what you are watching.
You will end up with having the best of both worlds and enjoying the best viewing experience at all times. Save my name, email, and website in this browser for the next time I comment. July 7, Understanding The Refresh Rate. Gamers Will Love Hz. Conclusion Are you thinking of upgrading your existing TV and splurging on one with a higher refresh rate? Lisa Hayden. You may also like. The problem with LCD and current OLED TVs is that they hold that image there for the full 60th of a second, so your brain actually smears the motion, thinking it should be moving, when in fact it's just a series of still images.
It's actually quite fascinating, but the details are beyond the scope of this article. I recommend checking out BlurBuster's great article for more info. The motion blur we're talking about here, despite coming from your brain, is caused by how the television works. This is separate from whatever blur the camera itself creates.
Some people aren't bothered by motion blur. Some don't even notice it. Others, like me, do notice it and are bothered by it.
Fortunately, it can be minimized. Refresh rate itself is really only part of the solution. Just doubling the same frames doesn't actually do much for reducing motion blur. Something else is needed. There are two main methods. The first is frame interpolation, where the TV itself creates brand-new frames that are sort of hybrids of the frame that came before, and the one that comes after.
This can fool your brain enough that it doesn't blur the image. Depending how aggressive the interpolation is, however, it can lead to the soap opera effect , which makes movies look like ultra-smooth reality TV shows. Some viewers like the effect, but it's generally hated by film buffs and others who pay close attention to image quality. There are different levels of this processing, where a little might reduce motion blur some, and not cause undue harm to the quality of the image.
Or on the other end of the "dial," it's cranked up so that there's even less motion blur, but the movement is hyper-realistic and for many, distractingly unreal. Some TVs let you choose how much of this processing gets applied to the image, others have just a single setting.
More on these settings further down. The other alternative is black frame insertion BFI or a scanning backlight. Visual defects, such as combing, can occur when deinterlacing is used on footage that is not interlaced in the first place. If you're picky, you may often need to change your TV's settings to accommodate the range of footage it may come into contact with.
All modern TVs offer refresh rates of Hz or higher, but 60Hz TVs are still around and may be two to three hundred dollars cheaper, depending on TV size. Some manufacturers now say they offer refresh rates of Hz or higher—usually for a much higher price—but in late , CNET reported that this is often just clever marketing , and that a number of Hz TVs actually have a refresh rate of Hz or lower , only with added smoothing effects.
In any case, refresh rates higher than Hz probably do not add any obvious value outside of some decrease in motion blurring. Share this comparison:. If you read this far, you should follow us:. Diffen LLC, n. Comparison chart hz versus 60hz comparison chart hz 60hz current rating is 3.
What Is Refresh Rate? Frame Rate Difficulties Film can complicate matters, as it is typically shot at 24fps. Follow Share Cite Authors. Share this comparison: If you read this far, you should follow us: "60Hz vs Hz Screen. There's a feature called variable refresh rate VRR that aims to match the refresh and frame rate on-the-go, so if the frame rate of the game drops, the TV automatically lowers its refresh rate as well.
Learn more about variable refresh rate. TV companies will often market their refresh rates in ways to make it seem like it's higher than it actually is.
A company like Samsung uses the term 'Motion Rate'; the Motion Rate on a 60Hz TV is , while a Hz model has a Motion Rate of ; they effectively double the refresh rate to come up with this number, and there's no real explanation as to why it's marketed like that. These marketing numbers don't really mean anything, and you need to check the TV's specs to find the real refresh rate. Learn more about fake refresh rate. What this means is that the backlight turns itself off every few seconds, so it doesn't get too bright.
It's not visible to the human eye because of how fast the frequency is. Flicker frequency, like refresh rate, is measured in Hz because we want to know how many times it flickers every second. If the flicker frequency doesn't match up with the refresh or frame rates, it can create some image duplication.
As you can see in the images below, motion on the LG UN has image duplication because its backlight flickers at Hz; this is double the 60 fps source. However, the Sony XH has a flicker-free backlight, so there's no image duplication - the motion blur is caused by a slower response time. A refresh rate defines how often the screen refreshes itself every second. Although we can't see it, the TV draws a new image from the source every few milliseconds.
Generally, a higher refresh rate TV results in better motion handling, but it's not always the case as there are other factors that come into play with motion. It's important that your source's frame rate and the TV's refresh rate each match in order to create smooth, stutter-free motion. For most people, a TV with a 60Hz refresh rate is good enough since there isn't much 4k content that goes past 60 fps.
