Resolution

  • Number of pixels per one square inch is called resolution
  • Measured by number of pixels in horizontal by number of pixels in vertical.
  • Units are pixels per inch.
  • When resolution increases, images become crisper due to a higher pixel density. 
  • In fact, text and images may also become smaller because more pixels per square inch are being displayed.
  • For example, going from just 800x600 to 1024x768 would increase the total number of pixels by 306,432. Those extra pixels are added to the screen with the same amount of text, thus making the text appear smaller.
  • When resolution decreases text should appear bigger, images are not as crisp, and performance requirements go down.



  • If two different sized screens have same resolution, image looks bigger in the wider screen, remaining everything is same.


 Examples:
  • Most of monitors have 1920 x 1080 resolution.


  • Our mobile phones have resolution 720 x 1280 in common. Depending on the type of mobile, it changes.


  • We normally adjusts the quality stream of video in Youtube.
