 Refresh rate, Resolution and Dot pitch with  reference of computer Monitor and video card

(a) Refresh rate:

Refresh rate is the number of times your phone screen (or any electronic monitor or display) updates with new images each second. For example, a 60 Hz refresh rate means the display or monitor updates 60 times per second, while a 90 Hz refresh rate means the display or monitor updates 90 times per second.   

(b)Dot Pitch:

Dot pitch (sometimes called line pitch, stripe pitch, or phosphor pitch) is a specification for a computer display, computer printer, image scanner, or other pixel-based devices that describe the distance, for example, between dots (sub-pixels) on a display screen. In the case of an RGB color display, the derived unit of pixel pitch is a measure of the size of a triad plus the distance between triads.

(c) Resolution: 

The graphics display resolution is the width and height dimension of an electronic visual display device, such as a computer monitor, in pixels. Certain combinations of width and height are standardized (e.g. by VESA) and typically given a name and an initialism that is descriptive of its dimensions.
