Real-World Benefits of 240 Hz Debated
While the option of 120 Hz for HD sets may be the latest to promise better displays of sports and other action scenes compared to the more typical 60 Hz, now comes 240 Hz—which likely be added to some higher-end HD units in 2009.

But like the debate regarding 120 Hz vs. 60 Hz, whether 240 Hz will make a “noticeable” difference (quite literally) to the typical customer is arguable. While inclusion of 120 Hz typically adds a couple of hundred bucks to most HD sets, it’s expected that the new add-on of 240 Hz will do the same.

While some CE makers like Sony are predicting that 240 Hz will soon become a ubiquitous quality of all HD products, as it says 120 Hz has already become (a debatable point, to date) some analysts voice skepticism that most viewers will never discern the differences of 240 Hz and 120 Hz (and likely will never see a side-by-side comparison to make it a bit less difficult.)

Other industry observers have chimed in and said the obvious benefits of 240 Hz have yet to be proven, according to the Wall Street Journal.

Sony soon plans to offer its first 240Hz models with price points of about $4,200 (without mentioning screen sizes). That’s more than twice as expensive as Sony’s current 120 Hz units, and more than three times steeper than many of its 60 Hz models.

The televisions in my home are all 240 HZ, but my HD cable service is by Com and it seems to be 60hz. How can I appreciate the difference of 240 HZ (or 120 Hz for that matter) if what is coming down the line is 60 hZ?

As far as I can tell 120hz makes sense because it allows the reproduction of both 60 hz video and 24 fps (hz) film without having to interpolate frames. The motion blur that it is supposed to remove to is defined by the rate at which the materail was recorded. So unless you have a source that is recorded at a frame rate (hz) that cannot be divided equally into 120 or you have a frame rate (hz) that is higher than 120 fps (hz) I don't see what 240 hz does for you.

Terrible review, please never start two consecutive sentences with while. It makes your reader cringe. The difference between 120 and 60 is easy to see if you actually have good 120 model with anti-judder. Trust me if you cannot tell a difference between the two, then you have not seen what 120 hz can do, it is remarkable.
