HDMI cable

Hi,

I have a SamSung HDTV which is capable for 240Hz. But why there is no
HDMI cable which is 240Hz (only ones I find is 120Hz) and why the
bluray player I see does not say what Hz it can support?

For the life of me I cannot understand why any good HDMI cable would not
work at 240Hz.
It's any HF content that could become an issue

you have no 240hz signals to feed it.
blu rays - 24hz.
tv, 60hz
240hz is just the rate at which the screen updates - by repeating each
frame a number of times and trying to guess what might be inbetween.

Therefore anybody hyping a 240Hz ready HDMI cable is,well, conning the
public!

Stocked right next to the HD TV antennas.

Any different from digital ready cables to begin with?
But I am happy with my Hi Def coffee table........

As others have explained, it is the processing in the TV that increase
the displayed frame rate by motion interpolation. The highest input
frame(field) rate that any of these TV:s can work width is (to my
knowledge) 60Hz.

Assuming that you like to know more about the 120/240Hz feature I
include below an explanation on how I understand it:
-----
240Hz is an attempt to take a step further in the same direction so
first a discussion on the 120Hz:

The first scenario is with material that has truly interlaced
content at 60Hz, which shows the objects at a new position in each
field (= half frame) .

Consider an LCD with essentially a steady back light.
The problem here is a blurring that is created in our eyes when a
picture is shown for 16ms at one position on the screen before it
moves to the next position and is held still. The blurring is created
when we try to follow the motion with your eyes (of a scrolling news
ticker for example).

In this scenario the goal is to reduce this blur width by moving the
objects on the screen to a new (calculated) position between the
positions in the input material. 120Hz (8ms) means that the blur
effect is halved. Interpolating to 240Hz should decrease this part of
the blur further, but there is also a response time in the LCD pixels
that might limit the visible advantage.


The second scenario, which for me is more important, is when the
material is from the low frame rate of film. (In Europe it is common
to play back 24Hz material frame by frame in a 2:2 sequencing so
that the shown frames effectively is showing as progressive material.
That means that we don't have the 3:2 "judder" but the displayed
motion is 25Hz and this is so low that a low frequency "judder" or
stroboscope effect is visible.
This is similar to the 24Hz from a Blu-Ray when played back at 24Hz.

The goal when processing such material is to achieve a
smoother motion.

In both these scenarios, the key point is that new positions of the
objects must be calculated in the created intermediate frames.

The discussion above is based on LCD that is backlit with effectively
a steady back light but the low frequency stroboscope effect can also
be seen on plasma panels.

Yes, and it cost only three times that of the regular, old-fashioned
analog coffee table. Looked awfully similar, though.
