Hi,

I just bought a new Samsung Series 6 LED/LCD TV. On the box it says 200Hz. The salesman explained to me that it's really 100HZ but they have some method of speeding it up to 200Hz in some circumstances. That's fine, 100Hz will do me. The thing is, when I switch it on and go to HDMI it says on the screen HDMI 1920 x 1080i @ 50Hz. What's going on? My reason for upgrading my previous LCD was because it was only 50Hz and I thought I'd bought one running at least at 100Hz. I can't find any way of changing the speed of it.

What's going on here?

Thanks for any advice.
Pugwash.

This is more than likely because the output device can only output upto 50Hz or is set to output at 50Hz

is is probably an input specific setting where the input used will determine the refresh rate. There may be a setting similar to Sony motionflow where you can specify an extra burst to the refresh rate. It may or may not make your viewing better.
On our Sony, putting it up to the maximum makes things look like a video game, which is a bit weird.

It's very probably describing the input sources details.
ie that description on the screen is what the device on hdmi is outputting.

You'd need to check the manual to see for sure what it's explaining and if you need to do anything to get it running 'properly' at 200Hz.

It is indicating the video source details. What have you got connected to that hdmi port? If it is something like a MySkyHDi, that is normal. The frame creation involved in doubling (or quadrupling) takes place within the TV after the source characteristics are sensed at the hdmi port.

There will be a setting in the video setup to set or deselect the 'clear motion' (or whatever the Samsung name for it is). Some people like the reduction in judder on panning that it provides, while others think it makes the picture look over-vivid.

And for the record...
The 200Hz claim is just marketing BS. I'd say it's about as useful as comparing dynamic contrast ratios.
The TV can create 100 frames per second at its maximum, but they claim their amazing processor / backlight performance etc etc etc can 'in theory' make it equivalent to a 200Hz TV. *Yawn*

No way, 200Hz is 100 x better than 100Hz, that's like 100% better! 
And some panasonic TV's have 600Hz written on them, so that's like 500 more than 100 so it must be like 500% better or something.  That must be amazing.  I'm just waiting until someone brings out a 3D 1000Hz TV, wow, just think of it, how cool that would be.....

I'm personally yet to see any kind of trumotion or clear motion 100-200hz technology, that I haven't wanted to vomit at when viewing in that mode.
They're a complete waste of time. And make the motion look false... Stay away!..

Hi Guys,

Thanks for all the replies. It sounds like its's the DVD player that is connected to the HDMI that is causing this. Do I need to pugrade the DVD or will the TV still run at 100Hz internally?

truemotion or whatecer you want to call it on different brands make things look "weird" in my opinion.

When I 1st got my TV with this feature I turned it on and things just looked strange. Its very hard to explain.

Hated that stuff ever since pixel plus.

The only things that look better on it are scrolling credits on a solid background.

Is this the same as the "intelligent frame creation" that my Panasonic 50V20 has?
If so, I'd agree with the comments made above.
Things are MUCH better now I've turned it off.

The effect it has is very odd, as if a trail of distorted space follows every moving object, lagging by a few tens of milliseconds; or, as if every moving object is encased in a thick glass shell that distorts the image of background elements.

What were Panasonic thinking?
Actually, never mind the "what". Were Panasonic thinking?

Source > TV Processing > Output

DVD/Bluray movies are typically 24 fps, TV is typically 25 or 50 (PAL), 30 or 60 (NTSC).

Converting a 1080p/50 or 1080p/24 source to 1080p/100 or /200 requires simulating the additional frames in some way, since they are not in the source. There are three ways to do this: interpolation of new frames, repeating the original frame multiple times, or making every other repeated frame a black frame. Motionflow creates these addition frames by the first method—temporal interpolation.

The 100hz or 200hz feature on your tv is probably using motion interpolation to insert calculated frames in between the real frames from the source in order to try make video look smoother.

Because these are not "real" frames from the source and some magic is used to create them these features can introduce artifacts.

Some people like it, some people hate it... you always want to turn it off when gaming.

To answer your question.  No you don't need a new DVD player.  Your TV will run at 100Hz as long as you tell it to in its settings menu. 
Having said that you could convince yourself that you do need a new BLURAY player, because new gadgets are always a good thing Laughing.......
