When every one of us is buying a computer monitor there are some things to consider that will ansure we are purchasing a product that meet all our needs. You will won’t find any new analog Cathode Ray Tube (CRT) monitor, most of the are outdated as technology, and you will probably find some second or third hand CRT monitor if you search well enough. They have been replaces by the thinner and brighter Liquid Crystal Display (LCD) flat panel. The advantages of LCDs are visible: they consume less power, emit less radiation and take up less space.
The 3 main panel technologies currently used in LCDs are: vertical alignment (VA), twisted nematic (TN) and in-place switching (IPS). Samsung created a new panel tech in 2011 called Plane to Line-Switching (PLS). Monitor manufactures uses TN for making most of consumer monitors.
