Smaller screen phones. What other monitors are. But only those designed to monitor different objectives, both used the technique only.
1080p, 1080i and 720p
Section A: resolution (resolution).
The first thing you should understand the resolution (resolution) of your TV - from the fact that before each new HDTV (microdisplay, LCD, DLP, LCoS, Plasma and directview LCD) can display resolution 480. lines, 720 lines and 1080 lines (more: HDTV support PAL system can display 576 lines of resolution with - the translation).
Many people still think that "bigger is better (bigger is better)" ... very much a high-resolution TV. The more detailed the picture will have only increased. But the problem is that these ideas are not always the reason is that even your TV screen much smaller size of the color point (pixel) is even smaller only. When the size of the pixel level to a very small. You will not be seen from the difference between the definition above. With lower resolution than longer.
Let us a preview. Suppose you're reading this article on the giant screen size 350 inches if you walk into this giant screen near you. Then look at the letter one. Suppose a point (.) As you like, you can see that the point here is comprised of multiple pixel to pixel Sort close together below the image
.
The image will be noticed. See you there, perfect. And good details. When the number of pixels, which is assembled here is you have to count exactly 20 pixels.
Here we try to reduce the screen resolution on the same 350-inch by half. When we go see nearby. At the same point. We will see it become like this.
In the second picture will notice that. Point of view it is not perfect here longer. Because it's not so much the number of pixels is enough to combine a point here is that it seems that theory. "How much more detailed view. More pictures will look good only "as I have said previously will be required. But it is not so. Because we look at that this point of view. "Closely" on the screen size of 350 inches.
Now, assuming you are sitting reading this article on the 19-inch screen size, we try to point the other point of view Let.
Where you can see consists of 4 tablets pixels based on pixel resolution of your screen. (And the resolution you set the control panel - a translator), visit fancy write that. If you adjust your screen resolution up to a 38928282 x 38928282 you will see a different point that there? ... Yes, some do not see? Although when you adjust the resolution increases. And this resolution will make the point that is comprised of 100 tablets tablets pixels you will not see the difference of it. Work? Point comprises 4 pixels will see "exactly identical" to the point that consists of 100 pixels fact that small details may be lost, but with the screen size is not large. Your eyes can not tell the difference of point to point size size 4 pixels by 100 pixels found with 19-inch screen size.
For that reason. Allowing the TV to a 720 line display is good enough any more. TV on the 1080 line will have to depend on the size of the TV itself. If even a small TV. And pixel size much smaller. We will not even notice the small little details that have disappeared.
What factors like whether these are subject to the human eye view, the size of the screen to display the distance between the audience. The following chart shows the relationship between the resolution of the screen (resolution) with viewing distance (viewing distance) and size of the TV.
Based on the above chart. Suppose you are purchasing HDTV screen size 40 inch ... the only way you can tell the difference between 1080p with 720p resolution is sitting watching TV at or near term than the 5 feet. If you buy a 50 inch screen size appropriate term would be 7 feet, 60 inches screen size will be 7.5 or 8 feet, therefore if you buy a HDTV to watch sitting in the living room to watch the regular term of most people. You will not benefit from 1080p resolution no.
Another theme that has most people do not know. That I want to say before we get to talk about is ... Interlace and Progressive
I hear many people always say that. "I have a TV version xxx 1080i is fine enough, I was more beautiful than the 720p images significantly" - which is indispensable in almost every case these people will see the difference between 720p and 1080i with here is why. ...
(More from the translation: the author is said to 480p/720p TV can receive a 1080i signal is).
If you have a TV microdisplay (DLP, LCD, LCoS or Plasma and directview LCD), the receiver has the highest 1080i - Virtually all of these TVs will support the highest resolution only 720p many people might argue that I am ". blah! ... I set my TV at 1080i resolution to always "ครับ ... Yes, you can set resolution to 1080i, your TV because it supports the resolution was. But the problem is. Processing unit within your TV, it only works at 720p resolution, which means that 1080i signal that you enter into the TV. Will be processed and reduced size (downscale) to 720p to display on screen. Therefore, switching back and forth between 1080i to 720p, it does not affect the quality of images displayed on the screen, but a 1080i image is motion artifact, which will make it more difficult than. (I will explain about this in Section B).
For someone with a CRT TV and argue a lack of dance wholeheartedly that display your HD display has a beautiful view over another free xxx - I have described here that CRT monitors are able to receive HD signals but it can not be true. display resolution that you entered the signal definitely. (The limitations of the processor inside. And the actual screen resolution in the last paragraph - the translation) you see that picture come out better view when you enter into the HD signal because the principle is "loss of detail".
"Loss of detail" is the same principle used to photographers who take pictures with the lens / filter soft focus long years since the elements of the face that people (not including the full range of facial - translator). When the camera close-out will not see well. Photographer must make use of soft focus images come to see Moore (blur) the image slightly to see out beautiful. This same principle was applied to a CRT monitor by using the same methods and softening blur to the image signal not good to have a better view. If you compare the image from CRT screen with a truly HD picture and you will see a difference indeed.
In other words. Although the TV will ensure you get 1080i signal but it does not mean that it will display the resolution. Actual resolution your TV is expressed 720p.
Next topic, you should understand. Is on the differences between the images with a Interlace Progressive Let's read that some work?.
