If you saw the Quality option on YouTube when you play a video and you’ll see 1080p HD, 1440p HD, and other options, you’ll already have some idea of what are Display resolutions.
So a Resolution is basically the total measure of the number of pixels in an image or what is displayed. If you want to increase the quality, you need more pixels.
Going back to resolutions, those commonly used video resolutions are called ‘Formats’, like High Definition (HD) format or just simply say HD will do.
To get the total Resolution, here’s a simple equation:
Resolution = Pixel width x Pixel height
Now, we will show you what are the most common resolution used to date:
|Resolution||Common Name||Pixel Size|
|Standard Definition (SD)||480p||640 x 480
|High Definition (HD)||720p||1280 x 720
|Full HD (FHD)||1080p||1920 x 1080
|Quad HD (QHD)||1440p||2560 x 1440
|2K video||1080p||2048 x 1080
|4K video or Ultra HD (UHD)||4K or 2160p||3840 x 2160
