Well, your display will show a number of image per second equal to its refresh rate. If you want to display a 24 fps movie with a 120hz display, you will show each image 5 times in a row, resulting in 24*5=120.
If you try to display the same movie with a 60hz rate, you will need to show some frames 3 times and some frame twice to make 24 images fit in the 60 available slots. We call this 2/3 pulldown. It looks like a judder effect, especially noticeable when the camera pans (move sideways). Indeed, some frames will remains on screen 33ms and others for 50ms. In other terms, this means the frame rate will jump from 20 to 30 all the time and 20fps is pretty damn low.
Setting your display to 24Hz, can resolve this, but again, movies aren't real 24hz, they are actually 23.976 fps. To sync the display and ensure no frames are dropped, you can distort slightly the audio (speed up) to make it fits with a real 24 fps. This will not be noticeable but it will prevent frame being dropped and the media will now be 24hz. Reclock does this well.
Now, this comes as a surprise. The motion enhancement effect (AMP) of Samsung D630 resulted in very large amount of stutter (lag, frame skip or pauses) at 60Hz. It was so bad I thought the TV was defective. However, it works very well with 24hz. Watch BBC life or Planet Earth at 24hz with AMP is very impressive and smooth. While no frame are dropped, it seems that AMP misses a few times per minute but it is still infinitely better with than without.
However, to make sure AMP and other image processing are available, you must not use the game mode or edit the source name as PC. Doing this, will require you to correct the image by adjusting the HDMI overscan. One also needs to reduce sharpness a little bit.
If you have a 120hz set with an HTPC, you should enforce a 24hz desktop refresh rate when playing movies and other 24ish sources. Autofrequency does this very well and fully automatically. You don't want to keep the 24hz on the desktop due to terrible mouse lag.
More testing to be done shortly.Edited by GrandMax - 6/2/11 at 1:33pm
