All LCD displays use progressive scanning, namely the whole frame is built up line by line rather than odd lines followed by even lines. Therefore, by default, 1080i will be converted to 1080p, but at a frame rate of 25Hz or 29.97Hz. 1080p sets take 1080i cable or satellite signal and convert (deinterlace) it, creating a progressive scan, meaning the picture is painted from the top to the bottom line (there are 1080 such horizontal lines) in a single pass, and this process (in the US) happens 60 times per second. 1080p is normally run at 50Hz (Europe) or 59.94Hz (North America). 1080i is normally half that frequency. Even if the signal is converted from 1080i to 1080p, there is no additional picture information and therefore, little is gained by the conversion. If the television actually does the conversion, it is worth doing a comparison between converted and unconverted to see which produces the most pleasing results.

∙ 15y agoWell, in my opinion 720p. But, technally speaking, 1080i is the better resloution. ---- The sharpness of picture will be as follows from the sharpest to the least sharp: # Watching 1080p signal on a 1080p TV set # Watching 1080i signal (e.g., on many cable programs) on a 1080p TV set # Watching 1080i signal on 1080i or 720p TV sets (see explanation below) # Watching 720p on any of the above sets All flat panel HDTVs (i.e., plasma and LCD), as opposed to CRT tube sets, are inherently progressive in nature. For marketing reasons, however, some manufacturers promote 720p (p for progressive) HDTV as 1080i (i for interlaced), mainly to signal, I suppose, that it supports 1080i signal and to improve their sales after 1080p models have appeared. The so called '1080i HDTVs' take a 1080i signal and downconvert the picture to the 720p resolution. Additionally, they de-interlace the 1080i signal and display it in progressive scan mode but in 720p resolution. However, According to a CNET reviewer, see the link below, the extra sharpness afforded by the 1080p as compared to 720p televisions is not noticeable when watching 1080i sources on 50-inch or smaller sets from the distance of at least 8 feet. Last but not least, according to some professional consultants in this area, the most important aspect of picture quality is contrast ratio, the second most important is color saturation, the third is color accuracy, and only the fourth is resolution, despite being easily the most-talked-about.

How do you convert a TV into a 1080p TV?
1080p and 1080i both refer to the format of a video signal. Any HD television will receive the signal and display it. If the television reports the signal standard being received, it will let you know what the signal is. Therefore, the television cannot be changed from one standard to another as it simply handles the incoming signal. Currently, broadcast HD signals are almost exclusively 1080i with a few formatted as 720p. Both are considered full HD even though the resolutions are different. 1080p is found on some local sources such as games consoles and Bluray players but has not yet made it to mainstream broadcast services.
Is 1080p or 1080i better for an HDTV?
A 1080p set has higher native resolution and supplied with 1080i (e.g., from some cable or satellite programs) or 1080p signal (e.g., from Blue-Ray discs) will provide sharper picture, especially visible on bigger sets (42-inch or more) and from up-close. 1080p sets are however way more expensive than 1080i ones. All flat panel HDTVs (i.e., plasma and LCD), as opposed to CRT tube sets, are inherently progressive in nature. For marketing reasons, however, some manufacturers promote 720p (p for progressive) HDTV as 1080i (i for interlaced), mainly to signal, I suppose, that it supports 1080i signal and to improve their sales. The so called '1080i HDTVs' take a 1080i signal and downconvert the picture to the 720p resolution. Additionally, they de-interlace the 1080i signal and display it in progressive scan mode but in 720p resolution. So, a 1080i TV set is in reality a 720p set, but many manufactures designated 720p sets as such as soon as 1080p sets came along. 1080p sets, on the other hand, take 1080i cable or satellite signal and only deinterlace it, creating a progressive scan, meaning the picture is painted from the top to the bottom line (there are 1080 such horizontal lines) in a single pass and this process happens 60 times per second (in the US). This means that same size HDTV sets designated as 720p and 1080i have identical native resolution of the display. Quality of the picture depends only in part from resolution, however, and according to some professionals the most important aspect of picture quality is contrast ratio, the second most important is color saturation, the third is color accuracy, and only the fourth is resolution.
Will a 1080p home theater system work with my Panasonic 1080i CRT HDTV?
1080 is a video standard and has nothing to do with the audio. Connect the stereo audio outputs of the tv to the inputs of the home theater. Check the HT menu to be sure it is set for multi channel audio on the input you are using.
What is the highest resolution?
1080p
When did 1080P Plasma TV come out?
2005, major tv companies such as samsung lg and Panasonic offered 1080p HD TVs
Is a 1080i TV compatible with 1080p cable?
Most modern LCD/Plasma TV's are capable of receiving and displaying 720i, 720p, 1080i and 1080p signals. Therefore your TV, if it can receive 1080i, should be quite happy with a 1080p signal.

Can you convert 1080i into 1080p?
The real reason to convert 1080i to 1080p is for archival purposes. In most cases, 1080i video is a program or film recorded off a television broadcast and "trapped" in your DVR (until a full hard drive forces deletion). However, those who still have a working Windows Media Center (hint: if you upgraded to Windows 10, you DON'T), are able to capture live 1080i broadcast video as playable files (*.WTV). These files can then be converted to the format of your choice. Herein lies the problem. Most (if not all) conversion software out there is unable to successfully deinterlace 1080i broadcast video. Certainly not in the most popular file formats (*.mp4, *.mkv, *.avi, *.mov, etc.) The result is noticeable motion blur. Hopefully one day the technology exists to do this without Final Cut Pro, After Effects and a whole lot of man hours at the professional edit bay. It will remain an issue until 1080p is adopted by the cable and satellite providers.
Your tv box shows 1080p but when you put it on it is saying 1080i how can you change that?
HD televisions are capable of displaying a wide range of image resolutions and timings. Most larger HD televisions will accept 1080p, 1080i, 720p, 576i, 480i and each of these in several different field rates. The standard broadcast format for HD is1080i with 720p used to far lesser extent. The television shows "1080i" because that is the signal being received. It will only display "1080p" if it receives a 1080p signal. Currently, broadcasters do not transmit 1080p and have no plans to do so for a number of years from now. When playing standard definition material into the television, it is likely to display 576i, 480i or perhaps show the letters PAL or NTSC to indicate the standard definition signal format.
What does an upconverting DVD player do?
It attempts to convert standard definition DVD's to 1080i or 1080p video.
Why is your 1080p television showing 1080i?
It's to do with the resolution. The 1080 identifies the number of lines that create the image, so 1080p and 1080i have the same number of lines. The letter stands for the type scan the TV uses. The P stands for progressive and the I stands for interlaced. Progressive will process the image twice as fast as interlaced and therefore produces better colour and clarity.
Will a 1080p signal work on a 1080i tv will it downconvert?
1080p signal may not work on a 1080i TV set. You may not get a picture, but just a blank screen. And that blank screen will not let you undo the changes because you cannot see anything on the screen. In this case, you may have to make an analog connection, such as a composite video connection, to your TV set just to undo the changes you have made. Or you have to press a combination of buttons on the 1080p signal source to restore the picture. I suggest you read the documentation that came with your 1080p signal source.
Dynex 46 LCD 1080p running at 720p change back to 1080p?
HD televisions are capable to displaying several HD formats. The most common are 1080i, 1080p and 720p. All HD signals will be in one of those three formats and the television will automatically accept and display any of the formats. The on screen report that the display is running at 720p is simply an indication that the incoming signal is in that format. Change the incoming signal to 1080 and the status will change to show 1080. Note that 1080i and 720p are both true HD formats and broadcasters are free to use either format. 720p is less used but it may be found on sports channels as it handles high speed movement a little better than 1080i.
Can a 720p TV be used as a 1080p?
All HD televisions are capable of displaying both 1080i and 720p formats. They are both considered to be minimum standards for HD capability. 1080p is a higher data rate than the others and a few older HD models cannot handle the format. Any of the later HD televisions will also accept 1080p. In all cases, the television will convert the incoming signal to a size to suit the native resolution of the television.
Do satellite TV companies offer 1080p signal in the US?
As of summer 2008, all satellite and cable companies in the US transmit only 1080i digital signal. When a cable or satellite service is used, there is no advantage of 1080p TV set over 1080i TV set. However 1080p sets usually come with some other more advanced specifications, which may make the image higher quality. Cable and satellite companies do not intend to upgrade the 1080i signal to 1080p in the near future, since this would involve high investment outlays and greater broadband capacity in their network. 1080p TV sets can fully utilize their potential when blue ray discs are played from DVD players.
Is dish network 1080P?
Some of the movies on PPV or Video on Demand can be purchased in 1080i. When an attempt is made to order a 1080i movie, the receiver will run a test to make sure the TV can handle this format.
Are there HDTV's that can switch between 1080p and 1080i?
If the TV is 1080p capable, it will switch automatically when it receives a 1080p signal. Keep in mind that not all cable and satellite systems will have this service. Look for the INFO button on the remote to see what standard you are receiving.
