When it comes to buying a computer monitor, we have to take care of many factors of monitor technologies before we make a decision. Let's take a look at the major features of these technologies.
Brightness-
LED monitors are much brighter than the other two technologies. Plasma is not as bright as LCD and LED. LED comes first, LCD comes second and Plasma comes third in brightness. However, it is not that the brightest is the best. It always depends on the conditions. If your monitor is going to be in a place where there is too much sunlight during the working hours, then you should go with LED or LCD. Plasma will be the worst in this scenario. For a dark room, Plasma will be a good option because you don't need as much brightness in a dark room as LED.
Contrast Ratio-
Contrast is the difference/ratio between the brightest and the darkest pixel/part of a screen. Contrast plays a great role in increasing the quality of the picture and making them more realistic. In the contrast arena, plasma takes the lead. Plasma monitors provide the highest contrast ratio. In the contrast benchmark, Plasma monitor comes first, LED comes second and LCD comes third. Recently an LED, Elite LED TV has been unveiled, which comes with advanced local dimming backlight. This makes the Elite LED TV's contrast ratio comparable with Plasma TV. However, this is an exceptional case. Normally LEDs don't have as good of contrast as Plasma TVs/monitors have. Most of the LED monitors have a lower contrast ratio as compared with Plasmas. LCDs don't have a good contrast ratio. On an LCD monitor, you will notice that the black portion of the screen is not really black in a dark room.
Energy Consumption-
LEDs consume the least energy and therefore they are the best choice when it comes to saving energy. However, they don't save as much money on energy as their price costs. LEDs have very expensive light bulbs, but at the same time they are energy efficient. Light emitting diodes, the technology at the back-end of an LED screen, produces light from the electricity in the same way a typical incandescent lamp produces but with quite high efficiency. This makes LED monitors energy-efficient. LCDs come second in energy consumption. These two technologies, LCD and LED, are somewhat similar to each other, therefore they both consume nearly the same amount of energy. However, LEDs consume less energy. Plasma TVs are highly inefficient with respect to energy consumption. In an environment where energy is the first priority, Plasma TVs are highly unfit.
Price-
If you want to go with the cheapest option, then LCD is the best bet. You can get a high definition large screen LCD monitor at an affordable price. It is the cheapest option available on the market. LEDs and Plasmas normally cost more than LCDs. LED is the high-end technology on the HD monitor list. The main reason for its expensiveness is that it uses the latest technology to bring the greener and most energy efficient product to the consumers. The use of the latest technology increases its production cost, but it helps the consumers in the long-run. Plasmas are in the middle of LCDs and LEDs.
Conclusion-
When buying a TV or a monitor, you don't have to go with the most expensive one or the one with the highest contrast ratio. Go with the option that suits you best. Buying the high-end product does not necessarily guarantee satisfaction. Also, buying the most cost efficient product doesn't guarantee that you will have a huge saving on your monthly bills. Study your condition and needs, then go with the option that suits you best.
