Price
The price mainly depends on the screen size. Common monitor sizes are 15-inch, 17-inch, 19-inch, and 21-inch. The price also depends on aperture grill pitch, resolution, and the number of controls.
Screen size
The size of the screen is the diagonal distance from one corner to another. The actual area for images is smaller than this.

Aperture grill pitch
This controls the space between the dots which make up the image. The less space between the dots, the better the display. Most monitors offer 0.25mm dot pitch but some go as high as 0.31 mm or as low as 0.22 mm.
Maximum resolution
The quality of the display depends on the number of dots which make up the image. The more dots, the better the display.
Refresh rate
The monitor refreshes the image on the screen all the time. The faster this happens, the less the screen flickers. You should have a refresh rate of at least 72 Hz.
Safety standards
These are international standards to control harmful signals.
Power-saving features
The power the monitor uses automatically reduces when it is not in use.
On-screen menu
Digital controls on the screen allow you to adjust the image.
Printers
There are many different types of printers. These include inkjet, mono laser and dye sublimation printers. Basically, you get, what you pay for. The more you pay, the better the printer.
Inkjet printers are the cheapest, but their print quality isn’t as good as the other two types of printer. They are expensive to run compared to mono laser printers, but are able to print in color. Inkjets are the noisiest of the three types of printer.
Mono laser printers are more expensive than inkjet printers, but give you a better quality of black and white output. They cannot print in color, but are the fastest type of printer and cost the least to run.
Dye sublimation printers are the most expensive type of printer, but their print quality is extremely high. They are quiet in operation, but are relatively slow and very expensive to run.
