240Hz LED TV The LG LX9500 - A Great 240 Hz LED TV 3D

I’ve said in many of my articles that the pace of advancement in 3D and LED TV technology moves fast and 240Hz LED TV is one result! We have seen processor rates and screen refresh rates go through the roof, from 60Hz, to 120Hz and now 240Hz LED TV is common with some sets even coming in a 480Hz refresh rates. I’ll answer the quesion “What is 240Hz LED TV“? in a minute, but first let’s look at some of the other advances in LED TV technology.

1080p 240Hz LED TV

Resolution has gone to 1080p and virtually every manufacturer of HD TV sets now has some form of “new technology” (with a very flashy sounding name) to counter image and motion blur. We also hear about “local dimming” where the more advanced LED TVs can actually turn off the LED lights in the black area of the screen making blacks about as dark and deep as it’s possible for them to go!

The aim of all this plethora of technology is to offer you a brighter, crisper and more colorful image with stunning contrast and an image that remains clean when you watch the most frantic sport (like hockey or soccer) or fast paced action movies (I just love those bangs and crashes!).

And, if you watch some of the later TV models, there is a difference for the positive in my opinion. Having said that a question we get asked many, many times when people are considering a new LED or 3D TV is this…”what’s the difference between 120Hz and a 240Hz LED TV and what does it mean for you?”

As I get asked this question a lot, I thought I’d write a quick article about it.

The Difference on 240Hz LED TV Sets

When I started to dig deeply into this issue the first thing I found out is that the content that is pumped out to your TV via whatever source (cable, satellite etc) comes in no more than 60Hz! Video is shot at 60 frames per second and, would you believe this, film at just 24!

So, what does the Hz mean then?

Well 60Hz, for example, means that exactly what I said above…60 frames per second. Now if you watch an old 60Hz Plasma or LED TV and then compare the same content on a 120Hz TV, I am willing to bet you’d notice a big difference (in favor of the 120Hz in case you were wondering). Most of the early version HD TV models (LCD or Plasma) had a maximum of 60Hz. A 120Hz will definitely demonstrate a clearer, cripser picture with stronger color and better contrast.

Now don’t get me wrong a 60Hz picture is still pretty good and quite stunning when compared to the old Cathode Ray Tube sets. But if you really want to benefit from native HD content, you really do need a set that offers at least 120Hz. For spare rooms that need smaller screens you can pick up an older model 60Hz at base bargain prices and they will serve you well.

Now, I’m willing to guess you probably have a question nagging away at you right now…so, Derek, if there is only 60Hz content available…how does a 120Hz set offer a better picture? Good question!

MEMC!

O.K, I’ll answer the question. Motion estimation and motion compensation…are you any the wiser? MEMC for short.

Motion Flow on the Sony Bravia XBR gives a superbly crisp and clear picture with little or no 3D Crosstalk

What this clever system does is insert an extra frame in between all the existing frames. Therefore you get double the frames hence 120Hz. The technology is so clever it actually predicts (or interpolates to use the correct term) what the minute movements between the frames and inserts an “interim” frame. Not sure that’s the right word, but you get the drift.

The result is a massive decrease in motion blur and a much crisper image.

Now imagine doing that again? Now you have 240Hz LED TV.

Outstanding Picture Quality

In my reviewing for Planet LED TV I have watched a lot of 240Hz LED TV sets. In my opinion, they are simply outstanding in everything they deliver to your viewing experience. Especially if the set employs local dimming which really does offer outstanding contrast making colors seem even brighter and more vibrant. I am a big sports fan, and since going to 240Hz LED TV I can tell you, sport is amazing. Alison wouldn’t agree and says I watch far too much of it, but even she admits to the amazing quality of the TV image.

There are two variations on the theme for 240Hz TVs. I talked previously about MEMC and for 240Hz three extra frames are added for each original. Again the technology is now so good the picture is enhanced. With three “generated” frames for every actual frame you would maybe think you might get a degradation, but nothing of the sort. The image is enhanced for sure. Go watch one and I know you will agree.

Secondly there is Scanning Backlight (240 effect): Other manufacturers use what is called “scanning backlight” technology. TVs employing this technology use MEMC once to go to a 120Hz picture, but instead of doubling the the frames produced per second, a special backlight flashes on and off (very, very quickly – so you can’t see the flashing) to achieve what has become known as the “240 effect.”

240Hz LED TV Major Technology Breakthrough

Vizio - Coming Up On The Rails With New Technology

In essence and in most cases a 240Hz LED TV TV is processing four times faster, and these sets confirm the major breakthrough in LED TV technology. Faster, more stable and far less likely to break down, the newest LED and 3D TV sets offer a major leap forweard in the quality of components in both the processor and panel.

A 240Hz processor in a major brand named TV (Sony, Samsung and more recently LG) assures you quality.  This is why you should go for one of the major brands – always check out our reviews as we keep on top of this. For example the latest Vizio and Toshiba sets are a huge leap forward in those brands technology and they are getting close to competing at the top end?

A higher quality TV, which will always have a 240Hz LED TV  processor, will also have almost the same quality picture the last day of its life, unlike the old Plasma screens that burned the screen and burnt out in pretty much 6 or 7 years.

These new LED TVs retain their vibrancy and picture quality and that means real value for moeny even if you pay a little more up front. Longevity and high performance (for not a lot more) are the keywords here.

And now 480Hz is here. To be fair I have only watched one 480Hz TV and not for long so I am going to reserve judgement. Some say the image is so good, it can show up programs and films that use tacky scenery and poor CGI. Some say you can see the paint lines and programming bugs! If that’s true, then the scenery makers and CGI proggies are gonna have to up their game somewhat!

The bottom line though is that a 240Hz TV will produce a significantly better viewing experience, great longevity and great value even if the up front cost is that bit more. So if you’re a big fan of sports and action movies (and who isn’t?) you won’t go far wrong with a new 240Hz HD TV…and power consumption is preety good as well. I hope that has answered the question “what is 240Hz LED TV?” Enjoy your new 240Hz HD TV!
