Display Measurements Display measurements are another factor to watch out for when you choose a new monitor. Some of important display measurement terms are explained below: The aspect ratio of a monitor refers to the horizontal size compared to the vertical size of the monitor. If you look back to the history of computer monitors, a typical old and classic monitor had aspect ratio of 4:3. But for the latest widescreen LCD monitors, the aspect ratio is 16:9/16:10/15.9. HDTV and Blu-ray are in widescreen and so 4:3 is phasing out.

- Contrast Ratio
The contrast ratio refers to the ratio of the brightest (white) to the darkest (black) on a screen. The higher the number the darker the black is displayed. For example, 800:1 represents that the white pixels of the monitor is 800 times brighter than a perfectly black pixel.
“Brightness is measured in nits. The average LCD currently is in the range of 250-280 nits. Ultra-bright models are capable of 450 nits. A higher nit level isn’t always good. In a darker room, 450 nits would make you reach for your sun glasses.” - Ahinc.com
- Diagonal Size
The diagonal size of a monitor refers to the distance between two opposite corners of the monitor screen. It’s common for this to be expressed in inches.

Display Resolutions is a term that generally refers to the number of pixels that can be displayed on a computer’s monitor.
The higher the resolution, the higher the potential quality of image or video. (The ultimate quality is determined by the
graphics hardware in the PC). Dot pitch refers to the distance between two pixels. Dot pitch is usually given as a fraction of a millimeter, such as 0.28 mm or 0.35 mm. A crispier image is produced when the Dot Pitch is lower. In simple terms, the smaller the distance between two pixels, the sharper the image.

The refresh rate of a monitor refers to the number of times an image is displayed on a monitor, repainted or refreshed per second. The refresh rate of a monitor is expressed in hertz. For example, a refresh rate of 85 indicates that the image is refreshed 85 times in a second. If your monitor supports low refresh rates, the screen will have irritating flickers and significantly strain your eyes. 
Response time refers to the amount of time it takes the crystals to change from one color to another (from fully white to black and vice versa) and the amount of time is measured in milliseconds. The lower the response time, the faster the screen refreshes. The latest display panels offer much lower response times and hence, higher quality displays. |
