samsung LED and refresh rate question (un55b8000)

[paulfromtulsa]

hello i have a samsung led model #un55b8000. I know that this tv has a refresh rate of 240hz but when i hit the info button on my remote it reads as follows. when watching a bluray it reads 1920x1080p 24hz. hidef channel 1920x1080i 60hz. regular channel 720x480 60hz. my question is what does the 60hz and 24hz stand for and why is it lower when watching a bluray movie? thank you.

Blu-ray movies play at 24 fps(frames per second) so the screen refreshes at 24hz to match the frames per second, so as to minimize and eliminate any judder that could occur. TV/Cable/Sat and DVDs all play at 30 fps, and using the 60hz refresh rate allows for the 3:2 pulldown that most TVs use as the easiest way to do that so it minimizes the judder that can occur.

your 240hz refresh rate is the speed at which the tv refreshes the screen to eleminate motion blur. The reason they use 120hz and 240hz is that they are both number divisable by 24 and 60. So what happens is the screed on a 240hz LCD is that it adds 10 additional frames every 1/24 of a second or 4 additional frames every 1/30 of a second to eliminate "Motion Blur"

To add to what Callas was saying, your TV is displaying the signal's resolution and refresh rate. This is useful since the TV is going to take that signal and upscale it to 1080p and 240hz.

that shows you only the info for the signal. You won't see any signal higher than 60 hz. Your tv will take that and do its processing to 240hz.

hz = fps...... refresh rate is a total different thing - normally measured in ms...
