nothing to do with refresh rate at all...
hehe, i love your confidence despite your incorrectness.
like resolution, the refresh rate of LCD/Plasma/DLP/etc HDTV's is a constant number, it is fixed...it cannot change...and there is NOTHING you can change about this...
in general most HDTV's that people have a 60hz...meaning they refresh at a rate of 60 times per second...now here comes the fun stufff....
we all know that to make video, it is simply a series of still frames, displayed continuously to create the effect that the image we are watching is actually in motion....60hz is generally considered to be plenty fast enough for the human eye to PERCIEVE that what it is seeing is a constant fluid motion...
there are two major flaws in the 60hz display....
1. Unfortunately some people still perceive a blur in the motion at 60fps...
2. Movies are filmed at 24fps (what you see in the theater)...Unfortunately...24 does not divide evenly into 60...because of this TV's need to perform 3:2 pull down in order to properly display the movie...that means each frame is not properly displayed...which is bad...
Now...enter the 120hz display...120hz displays always refresh at 120hz...and this is great because there are so many things you can do with them...
30fps material?...each frame is displayed 4 times in a row...awesome...
60fps material?...each frame is displayed twice...awesome...
24fps material?...each frame is displayed 5 times in a row...
this eliminates the need for any conversion or changing of the image and allows for the material to be displayed EXACTLY how it was intended...
Now...most sets also include some sort of motion processing...for example Samsung calls it AMP (auto motion plus). What these features do is actually CREATE frames that don't exist and slide them inbetween REAL frames in an attempt to further smooth out the motion...some like it some don't...this is an entirely different beast altogether...
there is NOTHING you can do to change the refresh rate of your TV...now that being said...not all 240hz sets are created equal some are not really 240hz and use tricks and gimmicks to simulate 240hz...
You really do not know much if you think modern LCDs still have to do 3:2 pulldown. And my z5500 supports 50Hz, 60 Hz and 24Hz content without pulldowns and makes it 200Hz, 240Hz and 96Hz.
