Hitachi led 65" TV have maximum 120hz.but I can get only 60 hz.how to setup to 120hz..plx help me


The television panel itself is a 120hz panel, and it should be understood that regardless of the picture being fed into the television, it will always display at 120Hz. There will also be some signals being sent at different resolutions, such as 480, 720p and 1080i/p. Since the panel is a 1080p panel, the picture will also be upgraded to a 1080p picture, regardless of the source.

What you're seeing in the INFO bar are the Hz-ratings that are being sent to the television. Most sources will generally send a 60Hz signal, some will send a 24Hz signal, but all of them will be upconverted inside of the television to 120Hz. This is done by internal processing inside of the television.

My tv is 1080p, but when I turned it on it says it's only 720p..


Your tv may be matching the source resolution. If your BluRay player, Cable Box, etc. is set to put out 720P, the TV will not / can not magically make it 1080i or 1080P. Otherwise, you should check the Menu for Picture settings and make sure it is set to 1080i or 1080P so that it is displaying the highest resolution possible.

How do I go from 480p to 1080dpi on my 65inch HDTV


If you're using an HDMI cable your display will automatically adjust the settings based upon the video source. Make sure that your source is capable of outputting 1080p. If it's an HD Cable Box or DVR, the maximum resolution it can display is 1080i. If you have one of these HD boxes, set it to only display 1080i as there will be a delay every time you change channels from a channel that is not naturally at 1080i.
If your source is a standard DVD player, it can only display images in 480i (or 480p if it is Progressive Scan) and therefore your TV will display the picture in 480 resolution. If your source is an upconverting DVD player it will display up to 1080p however, Keep in mind that DVD's are in 480 resolution and that regardless of upconversion (or upscaling, though improved, the picture will not be in HD.
The only way to achieve a true 1080p (not dpi... that's dots per inch... that's a printer term. The "p" is for Progressive Scan as opposed to an "i" for Interlaced) is from a 1080p source, i.e., a Blu-Ray disc player playing a Blu-Ray Disc with the use of an HDMI cable. Component Cables can achieve 720p/1080i only with your TV as it does not support 1080p over component cables.
As an aside, there are some media players that support 1080p output and some DirecTV Boxes and DVR's d oas well for 1080p Pay Per View movies.

My tv is Samsung TOCa750. How do I set it up for 1080p and 120Hz?


Resolution such as 1080p,1080i etc. set by your source of the signal, for example, if your cable box set to 720p that is what you going to get from the TV. Cable box is ont capable of resolution more then 1080i because there is nobody broadcast in 1080p yet. Only way you can get 1080p is BD player, upconverting dvd player or media player. 120 Hz is just a frame rate convertor - takes stendard 60Hz and doubles number of frames to 120. So, you will see 120 frames per second instead of 60.

4yr old Mitsubishi DL 52525, HDMI input vide problem


Are you sure its the TV and not the source? Are you sure its only the HDMI port on the TV? The only reason why you must HDMI is to get 1080p and your TV doesn't support 1080p. Its supports up to 1080i. Your TV has a native resolution of 720p which means it can accept a 720p image and not need to scale it, so the picture will look the best at 720p but will support 1080i. I would use component cables to connect your sources and set them to output 720p.

Mitsubishi 55 in. 1080 series


If I remember correctly, this TV has a couple of constraints that will cramp your style:

1. It supports 480i, 480p and 1080i. NO 720P
2. It has component video inputs, but NO HDMI. (as you stated)

There is no easy solution here, because I've never found an upconverting DVD player that would upconvert anything past 480p using the analog component outputs...

So..

Perhaps you can find an Upconverting BLU-RAY disk player that may allow older DVDs to be upconverted to 1080i via the component outputs.

MOST Blu-Ray players allow 1080i output via the analog connections on Blu-Ray discs, so perhaps there is your solution.

HD BOX SETTINGS


The Auto setting does exactly what it sounds like. It detects what the native signal is coming in e.g.(480i, 480p, 720p, 1080i, 1080p) and auomatically sets the box to the optimum setting. P=Progressive scan. I-interlaced. Progressive is much better than interlaced. 720p actually has more clarity than 1080i. Basically 1080i=520p! So I would set it at 720p if possible. But automatic is the easiest with the least amount of configuration. If you set it for 720p, then odds are you will have to set yout tv to 720p also.

Picture size/aspect ratio in HDTV and upconverting DVD


In the digital world, you can't have a 4:3 aspect ratio DVD title (720x480) on a 720p (1280 x 720) / 1080p (1920x1080) display without some kind of centering or stretching to some extent. (square vs rectangle) Now, on a 16:9 aspect ratio title (wide screen format) you should have any scaling issues regardless of the pixel resolution. Despite what the sales person told you, trans-coding ("upconverting") lower resolution titles to a higher resolution does not increase the quality of the image. Any attempt to do so would be only to try to reduce block noise and any kind pixelation at higher resolutions. (blurring square pixel blocks)

In the analog world, the quality of the image is based on the encoder and signal depth. If your TV excepts HD analog, you might be able to have your cake and eat it too. That would force your display to convert an analog signal into a digital resolution, letting the TV hardware do all the trans-coding. Manufactures are completely phasing out analog signal receiving, but might have the RGB RCA connectors for backwards compatibility. Eventually, it will not be supported and you will be forced to buy higher resolution content.

Hi - Here is a description of a few terms that might help, especially if you're in the market for a tv. If this answers your question PLEASE rate this as fixed. If you need more help just add a comment and I'll be glad to assist you further. Thanks.

High definition television is the highest form of digital television. It has a 16:9 aspect ratio, which is the same as a movie theater screen. This is possibly HD’s biggest selling point. The other is the resolution. High definition is the best available picture on a television. It comes in three different flavors: 720p, 1080i and 1080p.
What do 720p, 1080i and 1080p mean?
High definition programs are encoded with a type of resolution: 720p, 1080i or 1080p. The number stands for the amount of lines embedded within the signal. The letter describes the type of scan the television uses to display the picture. The ‘i’ means interlaced and the ‘p’ means progressive.
Why does the amount of lines matter?
The number of lines on a television is important because it allows for greater detail in the image. This is a similar concept to digital photos and how dpi determines print quality. The type of televisions all of us grew up watching had 480 visible lines on the screen. By doubling the amount of lines in combination with the type of scan, HD essentially doubles the quality of picture.
Does it matter if the resolution is interlaced or progressive?
The type of scan is arguable considering the amount of lines for each HD format. Progressive scan is a better type of scan because it doubles the amount of times the TV displays the image per one second in comparison to interlaced. Still, the difference between 720p and 1080i is so minimal that is isn’t an issue at all. While 1080p is better than 720p and 1080i, very few programs are made in this resolution so it really isn’t a factor right now…and, it might never be.
