120hz versus 240hz

Chris

Guest
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.

Thanks

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.

[*] 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.

This has nothing whatever to do with color rendition.

Who is Sylvia, anyway?

Nope. The only sets available use LCDs, plasma, and OLEDs.

I think when they refer to LEDs, it is LEDs used for backlighting
probably for an LCD.

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.

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 ...

Yup :)

Don't know in the US, but over here when folks speak of an LED
television, it's now accepted it's an LCD with a LED backlight.

Besides I've read that Sony have dropped their plans to go to large
scale manufacture with OLED for the moment.

Wonder what name they'll invent for proper LED TVs when they arrive?

And why aren't all LCD sets known by the name of the backlight?
