 HD, 2K, 4K – What does it all mean?

Monitors are in more sizes today than ever before. But with all the resolutions to choose from – which one is right for you?  Lets’ start with the basics – screens are made up of pixels.  A Pixel is basically a point on a monitor that is composed of 3 dots Red, Blue, and Green.

And the term Resolution refers to how many pixels are on the screen both horizontal and vertical.

The standard from a few years ago was 720P, nowadays we’ve gone way past that.

  • 720 x 1280 — HD is 720p
  • 1920 x 1080 — FHD is 1080p
  • 2560 x 1440 — QHD (Quad HD) is 2K 1440p
  • 3840 x 2160 — UHD (Ultra HD) is 4K 2160p

Also, as monitor physical sizes have increased the need for more resolution has also increased.

This is because of the number of pixels needed to create sharp imagery. The term PPI or Pixels Per Inch basically measures pixel density. The higher the PPI the more pixels make up any image and create a sharper visual.

The benefit of a larger screen and higher resolution is that images onscreen are sharper and you can fit more windows and programs on-screen for increased productivity. For anyone using graphics or video programs this is a no-brainer, but even spreadsheets and web browsing is enhanced with greater resolution displays.
