Monitor size and resolution

The basic element to make up the visuals to a computer monitor is pixels. Monitor resolution is measured in pixels, the width and height of the screen. example 640 x 480. This means that the screen in 640 pixels wide and 480 pixels in height.

'You can see by the chart below how screen size and effective resolution are linked. Compare a 15-inch monitor and a 21-inch monitor, both set to 800 x 600 pixels: the 15-inch will have a higher resolution. Larger monitors must contain smaller pixels in order to maintain the same resolution, but when a smaller monitor is set to a high resolution, the images would be much too small to read. A 14-inch monitor set to 640 x 480 is very readable, while a 21-inch needs at least 1024 x 768. Here are some recommended resolutions for the different screen sizes:'

	14"	15"	17"	19"	21"
640x480	BEST	GOOD	TOO BIG	HUGE	TERRIBLE
800x600	GOOD	BEST	GOOD	TOO BIG	HUGE
1024x768	TOO SMALL	GOOD	BEST	GOOD	STILL GOOD
1280x1024	TINY	TOO SMALL	GOOD	BEST	GOOD
1600x1200	TERRIBLE	TINY	TOO SMALL	GOOD	BEST
