HDTV spec. question?
Sharp AquosLCD HDTV (64 engine and up)have a response time of 4 ms...Sony Bravia does not chronicle it's response time but pushes 120fps. sometimes 120mhz. Are these related at all? Which would result contained by a better pic? Are all tvs 120fps. or are most 60 fps?
Thanks for the tech. info
Answers: 1080 and 720 refer to both the number of pixel and also to the lines of resolution.
1080 routine a rectangle 1920 pixels wide by 1080 pixels high with a total of 1920x1080>2 million pixels.
720 finances a rectangle 1280 pixels wide by 720 pixels high with a total of 1280x720>900,000 pixels.
A frame is a intact picture. With progressive you get it displayed adjectives at the same time, beside interlaced you get it partly at a time (every other line)
The frames per second when you watch broadcast TV depends on the broadcast format. You either return with 720p at 60 frames per second or 1080i at 30 frames per second. 720 has smaller quantity resolution than 1080, but it updates more often so express motion doesn't look as jaggy on a 720p setting.
One complication with the frame rate is that movies are shot on show at 24 frames per second. Most TVs show 30 frames per second or 60 frames per second because that's the broadcast format. HD DVD's like blu-ray store the movie on the disc at 1080p at 24 frames per second.
When broadcasts convey a movie over the air or via cable, they "pullup" the framerate from 24 frames per second to 30 frames per second by making up on fictitious frame for every four movies frames and you end up beside 5 video frames (because 24 * 5 / 4 = 30). This creates video artifacts called "judder". TV's running at 60Hz can verbs this up a little bit, but one and only the expense of displaying some frames for a longer period of time than others.
A 120Hz TV is angelic because 120 is divisible by both 24 and 30. A TV like that can be set to any one so you can even display a movie at 48 frames per second just resembling in the movie the stage without any artificial artifacts created by the conversion to 30 Hz.
With your 120Hz you wouldn't be watching it at 120Hz unless you tag on the video processing (like Motion Enhancer) which makes up frames that are averages of the legitimate film frames that come formerly and after. I would tend to turn that feature stale most of the time.
You would use the electronic clock inside the set to count off time intervals to update the display at 24 Hz, 48 Hz, 30 Hz, or 60Hz (unless you do the video improvement running at 120Hz and have the set spawn up stuff to display which may or may not work so well depending on you and/or the source content).
And by the bearing, the faster the response time, the better.
Also make sure that your TV can adopt a 1080p signal at 24 frames per second.
1080 and 720 are an indication of both lines of resolution and the number of pixels. For example, 1080p would have a resolution of 1920 x 1080 which is 1920 lines of horizontal resolution and 1080 lines of vertical, and over 2 million pixels.
Response time and frame rate are not exactly like thing, but one is the result of the other. A faster processor such as the 120MHz will allow for background to...well...be processed faster, thus adjectives back on delay in the nurture that can be noticeable on TVs such as LCD. Not adjectives TVs have a 120MHz chip, but the highly developed priced new ones hold started using it. In most cases a TV with a 120MHz processor will not own video lag or ghosting. The same go for most LCDs with a response time specification 8ms or below.
So ultimately, the 120MHz processor probably does a better, more rationalized job of displaying the model, the human eye will only become aware of so much difference until the speed becomes a mute point.
