Screen resolution is the pixel count of a display, given as width by height. A Full HD (1080p) screen has 1920 by 1080 pixels, about 2.07 million in total.
Why it matters
More pixels give sharper images and more working space, but demand more graphics power and bandwidth. Common names are HD (1280x720), Full HD, QHD or 1440p (2560x1440) and 4K UHD (3840x2160).
Sharpness also depends on screen size, so resolution should be considered together with pixel density (PPI), the number of pixels per inch.
On high-density displays, operating systems apply scaling so text stays readable instead of tiny.
Example
1920 x 1080 = 2,073,600 pixels
3840 x 2160 = 8,294,400 pixels4K has exactly four times as many pixels as Full HD, so a game rendering at 4K has about four times the work per frame.
Common mistakes
- Running a monitor below its native resolution, which blurs text.
- Assuming higher resolution always looks better regardless of screen size.
- Forgetting that the cable and port must support the resolution at the desired refresh rate.
