Written by Laurence 9 November How many Hertz should my TV have? While looking for a new television, it's important to pay attention to the Hertz rating Hz. You can, for instance, choose from 50 or Hz TVs. This rate determines how fluid your image will be during rapid action scenes. If you often watch sports matches or action movies, go for Hz instead of 50Hz. What is Hertz?
Why Hz? Brand-specific vs native. View all Hz TV's. Brand-specific vs native TV brands always have their own names and calculations for refresh rates. Did this help you? Yes No. How can we improve this page?
And, in many cases, not at all. Hopefully, you will too. The quicker a picture is refreshed, the more it should help motion appear smoother to the human eye and have less flicker. As you probably know, video recordings capture live-action by taking a series of still images — or frames. If these frames are close enough together in time, then we will see this as smooth motion when played back. Historically, the frame rate of analog video was based on the frequency of the local power supply. To save bandwidth during transmission, analog video was always interlaced.
The TV screen would then display these fields in the correct order to play the video. Many people just round these up to 30 and 60 frames per second.
So, they are actually two different rates. By the way, Hertz is a standard for describing the frequency of something, i. It can be used to describe the frequency of anything, not just video frame rates. Content recorded on film is traditionally recorded at 24 frames per second fps.
This still holds today — although some movies have been shot in higher frame rates. Simply because when movies were first made this was the lowest frame rate considered suitable for viewing.
It was easier and cheaper to build and use the hardware to film and display movies. And it looked good enough to the human eye to be realistic. Now, these frame rates were developed for analog TV systems.
The frame rate is sometimes added to the end of the TV picture resolution to describe the frame rate used:. The higher video frame rate will display smoother motion as there are more frames to capture it.
This is what determines how smooth the action will appear on your TV — not the TV refresh rate. So, why do we see different TV refresh rates quoted when we buy a new TV?
You can see quoted refresh rates of Hz, Hz, Hz and more. To begin with, you should understand that the maximum native refresh rate of a modern flat-screen TV today is Hz. So, the TV you buy will either have a Hz refresh rate — or the older standard of 60 Hz. So, if you are looking for the TV with the highest refresh rate, the answer is that most of them are the same as each other.
And, we now know that the frame rate of the content, and the refresh rate of the TV, are two different things. If we take a video recorded at 60p, then to display this image on a Hz TV, each frame is repeated twice:.
However, this makes no difference to how smooth the image looks, and there is no increase in detail of the movement. So, again, no difference to a standard 60 Hz TV. So, while there are some benefits of a Hz TV, you may not find many of them that useful in your day-to-day viewing. Anything else you see is marketing smoke and mirrors released by the manufacturer to make their TV more appealing.
Still, at times, tearing an effect of some of the image hanging behind the others or choppiness can be experienced. 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.
