LCD Monitor: What to look for
the measurement of the

Question is: how are manufacturers measuring this?
you want a ratio of at least
and
hopefully or
greater
(measured
in )
A good level is about 250 – 280
you want at least
degrees
Amount of between on monitor
You want less than (preferably less than )
the amount of time needed for a

you want at least 17 ms and preferably less

The set of all possible colors
The monitor’s ability to display the colors the graphics card produces numerically (RGB value)
Can be over 100%
Go for at least 70% (considered “normal”)Slide5

Uses more than the 4 basic (up to 9)
Use a special technology to transfer to

How to choose a printer
:

Higher
=
better quality.
600
means the printer can print 360,000 (600x600) dots in a square inch : measured in Most printers have different rates for text and for graphics
Initial CostCost of : How much is it to replace the ink or toner cartridgesPrinter in the pc that works with printer for printingSome just deal with printing, others do things like balance color, resize photos, adjust individual colors, etc.
The straighter, the better, and the heavier the paper the printer can handle. Straight (in front, out back) is better than (in front, out top), which is better than ( in front, out front)).
