I am sure some of you already know that the term "resolution" isn’t correct when it’s used to refer to the number of pixels on a screen. Let’s look at what today’s terminology is, and what it means. However, this also means that there are a lot more options to choose from, with something to suit almost everyone’s preferences. With the advent of high definition video and the increased popularity of the 16:9 aspect ratio (I’ll explain more about aspect ratios in a bit) selecting a screen resolution is not the simple affair it once was. For the sake of nostalgia, here’s a look at a once well-known CGA display. Regardless of the capability of your monitor, you’d still have to choose from one of the few options available through your graphics card’s drivers. CGA was first, followed by EGA and VGA–color graphics adapter, enhanced graphics adapter, video graphics array. The color graphics technology was first developed by IBM. In this article I would like to take you through a bit of history and explain all the important concepts. Today we have lots of options when it comes to displays, their quality and the supported resolutions. As time went on, you could choose better video cards and better monitors as well.

Windows came with a few preset options, and to get higher resolution or more colors (or both) you would install a driver for your video card. This is because at 1080p, the webcam and CPU have to process much more information than at 720p, thus slowing the frame rate down to 10FPS or lower, which in turn creates less fluid video.In days gone by, screen resolution (also called display resolution) wasn’t much of an issue.

You will find webcams that have HD-quality video 1080p resolution but have better quality video with less skipping or choppiness at 720p at 30FPS.
The higher the frame rate, the more fluid the streaming video will be. Frame rate is usually described in terms of frames per second (FPS). Frame Rateįrame rate is an extremely important specification to recognize.

When you see that a webcam can take up to 20MP interpolated photos, it actually means that the webcam itself doesn't have that capability, but the software can upgrade the quality of the photos to 20MP. The software that comes with the webcam is what digitally enhances the quality of the pictures. This doesn't necessarily have anything to do with the webcam itself. You may notice that a webcam may not have great video quality but is still able to take high-quality photos. (Image credit: Logitech) Photo Interpolation As you can see, the formula to arrive at both descriptions of resolution are exactly the same, just described differently. 9 megapixels (MP), or one megapixel if you round up (mega means one million). Taking our last example of 1280x720, or 921,600 pixels, this would come to. Megapixels are an image quality description usually associated with digital cameras. The more pixels that can be progressively scanned onscreen, the better the video quality. A 720p television will progressively scan 921,600 pixels (1280x720) on the screen every 1/60 of a second - older CRT screens used interlacing (switching between odd and even lines every frame) but progressive scanning provides a better picture. For example, 720p really means 1280x720 pixels, where 1280 represents the number of horizontal pixels and 720 represents the number of vertical pixels. The 'p' is short for 'progressive scanning'. While this is now a common resolution for all the best TVs, is something you're probably not going to be managing with a simple webcam. 720p and 1080p are high-definition resolutions, with 1080p being the best available (and likely built into the best laptops) until you get to 4K Ultra High Definition.
