Motion Clarity Index of 100 on TV ?

MoneyMate

Does anyone know if Motion Clarity Index and eg 100 Hz are the same, just bought a tv which has MCI of 100 but is stated as 50 Hz ?

I would be interested to know are they the same number to number. :beer:

Manufacturers now use their own measurements so can not necessarily be compared between brands. Examples include LG - Motion Clarity Index (MCI), Samsung - Clear Motion rate (CMR), Philips - Perfect Motion Rate (PMR), Sony - Motionflow XR and Panasonic - BLS (Back Light Scanning). All these figures are twice or more than the traditional 100Hz/200Hz refresh rate figures. No abbreviation indicates traditional measurement. Plasmas generally use a 600Hz sub-field refresh rate.

Thanks Norman Castle all great info, I know now :beer:

The manufacturer ratings (such as MCI) take into account the TV's picture processing capability and so forth to give an effective refresh rating. (for example, you may find that the TV can detect moving images and refresh those parts more often as it's quicker than refreshing the whole thing).


The native refresh rate refers to the number of times per second the entire screen can be refreshed by the TV

As I suspected then, it's a marketing term that can simply be ignored.
Films are 24 frames per second.
Our TV is 50Hz, interlaced.
Therefore 100Hz is just showing the same thing twice, or making stuff up inbetween, which can cause more problems than it solves.

Does this mean that the difference between 400 and 800 motion clarity rate is not worth bothering about?

WTFH

It's worth bothering about if you can spot the difference and it's important to you.
If you can't spot the difference, then you're wasting money going for a higher spec.

The best solution is to go to the shop you are going to buy from and compare two screens side by side.

Much like many people don't get much better picture from 1080p or the forthcoming 4k standards than they ever did on analogue on a CRT TV. It's one dimension to measure, but meaningless on its own, much like so much HDTV is so digitally compressed that all it does is look a clearer kind of crappy.

Basically, watch whee kind of thing you watch on a wall of TV's and see which you like. What's good for sport might suck for nature shows etc.

jicms - I don't know what those terms mean - what brand is using them? If it's 400hz and 800Hz I'd certainly ignore them. British TV is broadcast at 50Hz interlaced. What are they going to fill the gaps with?! Blu Ray is often 24 frames per second so I don't see any advantage there. UNLESS you know that you are susceptible to flickering images.
paddyrg - I know what you mean (broadcasters squeezing the quality out of the picture) but we're talking about screen technology here - so those resolution measurements - the number of pixels the screen has, are still important.

There are two things going on here, native panel refresh rate (will be either 50/100/200 Hz) and manufacturer numbers for calculating how well an LCD/LED screen handles motion.....

Motion clarity index and such like ARE marketing terms for how well an LCD/LED display will handle motion. They do factor in the native panel refresh rate but also other factors such as the backlight and processor speed. Now on a LCD/LED when you watch fast moving action such as sports you may see motion blur, this is when things move faster than the screen can refresh or change the pixels......

So things like the motion clarity index are essentially a measure for how well the TV manages motion blur. The higher the number the better. They are LINKED to refresh rate but manufacturers mislead people into thinking they ARE the refresh rate. When in fact several different MCI or equivalent numbers can all share the same native panel refresh rates (but have faster backlights and processors which mean they handle motion better).

So yes it is a "gimmick" in some ways, but no it isn't something that is irrelevant and getting a higher number can matter if you watch fast moving action.

iwb100 - I still think they're gimmicks. Response time is a much better way to measure with less chance of manipulation by manufacturers.
Fortunately with the big names at least, the newer LCD screens are far better with motion so this issue has become less important.
