I am considering the purchase of an LED television. However, before I do, I would like to know what the difference is between 120 & 240hz; other than the numbers. I've done some research, but there seems to be a wide array of conflicting opinions. I know that it has to do with refresh rate, jitter, and blur. So, if anyone has some straightforward input on the matter, I'm all (grateful) ears.
An alien with 240Hz eyes might appreciate[*] the higher frequency version, but unless you're such an alien living on Earth incognito, don't waste your money.
Sylvia.
[*] Ignoring the fact that colour displays are finely tuned to the way that human colour vision works, and an alien would likely wonder what we'd been smoking.
First, the only televisions that use LEDs use OLEDs. There are none using conventional LEDs.
Second, there are no strict definitions of what these refresh rates mean. In some cases, the set generates an interpolated image at that rate, in others, a blank (black) raster is inserted. Some sets combine both.
I don't like this enhancement (which was one of the reasons I bought a plasma set). It has a nasty side-effect -- it makes motion pictures look like video. This might be fine for a TV show; it isn't when you're watching movies. Be sure that whatever set you purchase has some way of defeating it the enhancement.
You need to actually look at the sets you're considering with program material you're familiar with.
Your Wiki reference says it all. These are NOT LED televisions, as we discussed on here a few weeks back, no matter what misleading crap the manufacturers use to try to convince dumb punters otherwise. These so-called LED TVs are conventional LCD sets, with all the drawbacks of that technology, but backlit with LEDs instead of CCFLs.
Seconded on all counts, and also the reason that I recently bought a plasma TV (Panasonic, 50" full HD panel, 400Hz). I have not seen a single thing about this TV that I don't like so far, unlike the LCD TVs that I have in the house, and the LCDs that cross my bench for repair, all of which suffer from motion artifacts, scaling artifacts, and motion blur ...
This plasma TV has produced absolutely stunning HD pictures from the Winter Olymics, with not the slightest sign of motion artifacts of any description, even on the fastest content like downhill skiing, and bobsleigh etc. In contrast, the same content that I have seen on LCDs, has been perfectly dreadful.
Since the subject's been broached, may I ask: are you a woman? I ask because, well, 99.9% of the other posters here aren't, and it's unusual to see a woman posting in such a newsgroup (actually pretty much on Usenet in general, a few newsgroups excepted).
None of my business, I know, but I'm curious.

You were wrong, and I'm man enough to admit it.

Ah that explains why I cannot watch these things for more than a few minutes, I'm an alien. Would anyone know what the equivalent refresh rate is for good old CRT technology ? As far as fast movement across the image is concerned, motion jitter or judder or whatever the term is. What refresh rate would have to be there before I cannot tell the difference between that part of the technologies?
And it's time something was done about that. The manufacturers are relentlessly plugging this as though it's some new and wonderful display technology, and it's not (although I have to say that the TV ad campaign that was running here seems to have stopped now). It is misleading nonsense, and although all civilised countries have laws against misleading advertising, for some reason, they seem to be letting this one go, presumably because like you, they don't have any understanding of what is actually *meant* by the term, rather than *implied* by it.
By the way the OP was talking, he doesn't understand either, and is in the process of *being* misled by it and, since he asked, it is up to those of us who *do* understand, to help him out with his question, and stop him potentially wasting his hard-earned on something that is not exactly what he thought it was.
Now if you have anything sensible and informative to say on the issue, go right ahead Philip. Otherwise, if it's just more of your normal anger and abuse that's festering ready for you to unleash, go have a beer or whatever instead, and chill ...
