FAQ

Those who are looking for an answer to the question «Why do plasma tvs have only 60hz and lcd tvs have 120hz?» often ask the following questions:

👉 What is 120hz or 60hz in tv's?

North American television delivers images 60 times each second. Technically, most television standards deliver half an image each time, with the full image being delivered 30 times each second. This is known as a 60Hz field rate. Some televisions offer a 120Hz display. The television takes the original signal and adds a new image between each of the original images so producing 120 images every second. The aim is to make motion appear smoother and to reduce flicker. However, the process means that new images have to be created 60 times each second and this is a complex process. Similar techniques are used in broadcast systems and the converters cost thousands of dollars. $50,000 is not an unreasonable figure for a top end converter. Frame doublers inside televisions are manufactured at a much lower cost and are not as good as the top end converters. In many cases this won't be a problem but sometimes, the final output can suffer from lack of definition and juddering of fast moving objects on the screen. It is important to see the frame doublers at work before investing money. The test is very simple - if the image looks clear and smoother then without the doubler, it is worth buying. Remember to watch a variety of content, especially with fast movement. In Europe, television runs at 50Hz, so an equivalent TV will offer 100Hz display rather than 120Hz but the principle is identical.

👉 What is better 60hz or 120hz tv?

  • It allows the TV to generate frames between existing ones, increasing the frame rate to match up to the refresh rate. Most TVs have this feature; a 60Hz TV can interpolate 30 fps content, while a 120Hz TV can interpolate 30 and 60 fps content. This is why a 120Hz TV is an advantage over 60Hz since it can interpolate more types of content.

👉 Can a tv be upgraded from 60hz to 120hz?

Currently in 2014, there isn't a way to upgrade a television from a 60hz to 120hz. The only way to upgrade is to purchase a different television.

Actually plasma screens are in total 600hz but they are divided in 10 subfields, each of which run at 60hz. But in conclusion, 10 subfields of 60hz reduce motion blur almost to zero and look alot cleaner than 1 subfield of 120hz, 240hz, etc.

Can a 60hz tv display 60fps?

10,640. 4. Dec 15, 2012. #4. A 60hz monitor refreshes the screen 60 times per second. Therefore, a 60hz monitor is only capable of outputting 60fps. It can still feel smoother to play at a higher framerate than your monitor can display however, because input lag with your mouse will be reduced.

What is plasma in plasma tv?

The plasma in plasma TV is actually real plasma. Many people tend to think that plasma is something made up by science fiction novels, but it's actually closer to home then you might think. plasma is a state of matter like a solid, liquid or gas but with different properties. It is best described as being similar to gas, but is not exactly the same. The reason why plasma is used in televisions is because it can be manipulated into showing different colours. Plasma is matter heated to roughly 10,000 degrees and so if you pause an image on a plasma screen TV and leave on for a long time it will begin to burn into your TV. Plasma is often commonly found in households as it is used in light bulbs.

Can you watch 24p movies on a 120hz tv?
  • Depending on your TV’s refresh rate and the frame rate of the source content, these motion features can add two to four times as many frames to the original video. But just as a 120Hz or 240Hz TV can make movies look less like movies, it can also be the ultimate screen for watching 24p content as intended.

Will 120hz on a lcd tv affect a video signal from your tivohd or does 120hz just affect 24 frames per second sources?

A 120Hz television features a frame doubler. Normal television signals have 30 frames each second with each frame made of two fields so there are 60 fields each second. A 120Hz television is thought to eliminate some of the flicker from an image by generating intermediate fields between each of the broadcast fields. Whether or not it improves the image is a matter of opinion. Adding fields introduces small errors in the image and although more fields can be created, never can a frame doubler add information that wasn't in the original signal. The 120Hz feature refers directly to broadcast signals at 60Hz and not to 24 frame material. 24 frame material is derived from film and instead of being made up with two fields, the complete image is produced 24 times each second. A frame doubler will increase the rate to 48 frames per second if it takes the 24 frame material in it's native format. However, film is normally converted to a 60Hz signal using a technique known as 3:2 pulldown. This means that the first film frame will be sampled twice and will create two fields. The next film frame will be sampled 3 times and create three television fields. So, in 1/12 of a second, two film frames generate 5 television fields. If, at any time, the 24 Hz material is converted to 60Hz using 3:2 pulldown, the television will simply double the frame rate to 120 Hz. Indeed, the line doubler may use this technique anyway. The precise methods employed vary from one manufacturer to another so although it is safe to say that a 120Hz television will affect all incoming signals, the way they handle signals will vary. As a final note: European television runs at 50Hz, not 60Hz. Line doublers will convert to 100Hz. Also, 3:2 pulldown is not used in Europe. As the European frame rate is 25 FPS, film is run slightly faster than its normal 24FPS to comply with television standard frame rates. It means that films become 4% shorter on television than in a movie theater.

What is better a 240hz or 120hz for a lcd tv?

Television signals are broadcast at 60Hz, that is 60 fields every second. To make movement appear smoother and to reduce flicker on televisions, some models refresh the screen at twice or four times the rate of the incoming signal. Theoretically, the faster the refresh, the smoother the image will appear so 240Hz might be considered better than 120Hz. But, it's not quite that simple. Some people prefer this processing while others will say that it does not benefit the quality. Increasing the frame rate is not a simple task. Each additional frame needs to be created by examining the frames before and after with all movement predicted and calculated. It takes a lot of processing power to do it properly and the image processing still gets it wrong sometimes. The result can be smearing of the image or even adding some high speed jerkiness. These processes can never create information that was not captured originally so the end result always adds errors. Whether the end result appears better, worse or just the same is always a matter of opinion. Get into stores and see for yourself. If you like the effect of 120Hz or 240Hz refresh, it's a good thing to have. If you don't, then it's not worthwhile. If you are buying, remember it's your television so like what you like and not what you are told to like.
