Specs: Windows 7 Ultimate x64, 2.793 GHz / 2047 MB
So I am finally going to get a new monitor. The current one I have is a Fujitsu 17" Square monitor.

Now I have 2 options to choose from

First one is- Samsung S20A300B 20" LED monitor
Here is the link to the webpage:

Second one is- DELL IN2020M 20" LED Monitor
Here is the link to the webpage:

Both are widescreen monitors and now I am confused with these two. I have heard that there are monitors which have LED on the edges and do not give a good result and that they are same as an LCD, I just know that both these are LED Monitors but do not know that whether the LED is on the edges or behind the screen.

I want advice on which one is the better option. Which will give a better quality while watching movies because that is all I do. I don't do gaming.

✔ Best Answer
LED is a backlight used by LCD monitors. Both Dell and Samsung monitors listed use LED backlight.
IMO Samsung monitor is better(glossy black, external adaptor, use only 19w).

To to add what kuwese saiys, before LED back lights the back light was a CCFT (Cold Cathode Florescent Tube)

The problem with CCFTs was that they do not give a pure white light where LEDs do so you get a better colour rendition. CCFTs tend to be brighter than LEDS but LED technology is improving all the time and they do not require an inverter as CCFTs do which cuts down on the power consumption quite dramatically..

The back light, whether CCFT or LED is on the edge of the screen so the light goes between the different layers of material in the LCD assembly.

The names are confusing only. Almost all modern displays for desktop have an LCD display in front of some light source. That light source is either a florescent lamp(s) or a LED array.

Cold cathode florescent lamps are quite efficient. In fact they are more efficient than all current LEDs. The reason a LED display can be more energy efficient is because they can control a LED faster. They basically can't control a CCFL lamp in a monitor situation and they don't, they use the lcd to control. As to color they can correct for all of that from either source.

I think you could look at them at a store to be sure. Then include energy star as a consideration. Many LED systems can waste a lot of energy even in the off or standby state. It never hurts to put all of your computer stuff on a power strip and turn it all off when not in use.

Both monitors are Energy Star 5.0 certified. Now I think that Samsung is the better option like Kuwese said. Any other suggestions.

The liquid crystal pixels in the display do not produce light - they let through the white light or modify (color) or block (black out) that white light that is being produced by a light source behind the liquid crystal pixels.

The back of the display assembly is constructed such that the white light source has it's light evenly distributed behind the liquid crystal pixels - for conventional LCD displays , the CCFL(s) is(are) not directly behing the liquid crystal pixel grid - there are reflectors back there - I don't know whether that applies to LED LCD displays too.

The biggest advantage of an LED LCD display - which uses LEDs as the white light source behind the liquid crystal pixels - is, in theory, the LEDs have a MUCH longer useful life.

For that matter, I don't recall ANY led on a computer that has EVER burnt out.

CCFLs will burn out eventually, the same as any other florescent lamp (tube).

We get Topics here constantly about conventional LCD displays - LCD displays that have one or more CCFL(s) - producing an overall tint, or the display going very dim, or there being no display at all (blackness). If the laptop or monitor has not been subjected to a physical jolt, usually that's caused by the CCFL(s) being in the process of failing or having failed completely, not by the voltage inverter for it(them) malfuctioning or failing.
