Resolution

Give me an example of a resolution! Did you say 16:9? WRONG! That is aspect ratio not resolution. They are however directly related to each other. Read on to see how…

Some of you are familiar with term “Resolution” when it comes to computer monitors. And you would not be far of in thinking about it that way. Resolution dictates how many pixels can monitor (TV) display. If you have resolution of 800×600 pixels, that means that there are 800 pixels horizontally and 600 vertically.

Now, what is pixel you might be asking? Pixel is the smallest unit of light or part of and picture, that a display can show. You can kind of thing about it as atom in the compound, where the compound is the picture.

How does all this relate to a TV resolution? All the TV’s still do run on the pixels. If you are buying 1080p or 1080i TV you have 1080 vertical pixels. (Read “720i vs. 720p vs. 1080i vs. 1080p” for more detailed info) Now how do you figure the horizontal pixels? That is simple; remember the aspect ratio of 16:9? 1080 is directly proportional to 9 and 16 is directly proportional to horizontal pixels. With a little algebra you find out that the TV with 16:9 aspect ratio with 1080i/p has 1920 horizontal pixels. Don’t worry you do not have to do math is store when buying. Just look at the box and you will find 1920×1080 somewhere, if you are buying 1080i/p TV.

If you go to a store to buy a TV, you will probably not hear your salesman tell you something like: “This TV has 1920×1080 pixels of resolution. “ The will tell you that: “This TV has 1080 lines of resolution” And both statements are technically true, just the second one is more correct TV lingo. Each one of the 1080 vertical pixels belongs to one horizontal line of pixels, thus giving you 1080 lines of resolution. How many pixels are in one horizontal line? Well if you read carefully you would know that there are 1920 in each line. So, all together a TV with 1920×1080 pixels of resolution has 2,073,600 pixels all together. Feel free to count them, just bring a magnifying glass.

Why or how do I pick the right resolution for me? The simple answer would be that bigger the resolution the better. Let me give you an arbitrary example of why. Lets say you are deciding between two 50” TV’s, one with 1080 lines of resolution and one with 720 (ore near to that number) lines of resolution. Anyone who knows will tell you that there is no choice at all, and smart decision will be to get the one with 1080 lines of resolution (for more that one reason). Picture below will illustrate why. (keep in mind that it is over exaggeration, just to portray the point I want to make.)

1080p vs 720p

Let’s assume that the picture displayed is in full 1080 lines of resolution shown on 1080 TV on the left and 720 on the right. Keep in mind that both TV’s have are 50”. The TV with 1080 lines of resolution has more pixels to display than the TV with 720 lines of resolution, thus the 1080 TV generates better looking image.

Bottom line is; if you have choice go with 1080 lines of resolution. Trust me it is the better choice. (Read “720i vs. 720p vs. 1080i vs. 1080p” article to find out the difference between 1080i and 1080p)
