Screen Resolution or Aspect Ratio Size for HD and UHD 4K


Their are many reasons why you will need to know the correct screen resolution and aspect ratio size. Depending on the kind of device you are using, changing to the correct setting is important for correct operation and better display quality.

Screen Resolutions

720p Resolution:
– 1280 pixels x 720 pixels
– 16:9 aspect ratio (widescreen display)

1080p Resolution:
– 1920 pixels x 1080 pixels
– 16:9 aspect ratio (widescreen display)

Standard definition (SD) is used by older television models (before the introduction of flat-screens). SD resolution goes up to a maximum of 480p.

High Definition (HD) Resolution and Usage

Both 720p and 1080p are considered High-Definition (HD) and are used (and not limited to) by the following devices:

  • Gaming Consoles (PlayStation 4, Xbox One, etc.)
  • Digital Camera Video Recordings
  • Television Screens
  • Computer Monitors
  • Video Streaming Services (Netflix, Hulu, YouTube, etc.)

Ultra High Definition (UHD)

The step up from High Definition televisions is Ultra High Definition also known as UHD or 4K Resolution. 4K Televisions have become the new standard on the market and are getting less expensive as the months go by. 4K UHD resolution is 3840 x 2160 pixels and the step up from this one is 8K UHD which runs at a whopping 7680 pixels x 4320 pixels. Both Sony and Microsoft came out with UHD versions of their PlayStation 4 and Xbox One consoles to accommodate with the new emerging technologies.

UHD will become the standard name for the newer televisions that hit the market, especially when resolution hits 16K and 32K in the next few years.
