I am looking to buy a 24" monitor. Sometimes I watch movies, but mostly it will be for document editing and programming (Visual Studio). I have found a product I like, and it has an 'LED backlit' model and a standard model for about the same price.

I have read that backlit displays have advantages, but could they be too bright/high contrast for working with text?

(Note I'm not looking for shopping recommendations - just advice on how 'backlit' monitors display text.)

Is this question about LED/non-LED monitors or about monitors which use LED backlight with LEDs on the edge of the screen and lightguides versus monitors which actually have LEDs behind the screen? –  AndrejaKo Nov 26 '11 at 12:25
    
@AndrejaKo It's the BenQ G2420HD vs BenQ G2420HDBL. –  James Nov 26 '11 at 12:35
    
That makes it then a question about LED/non-LED monitors. –  AndrejaKo Nov 26 '11 at 12:39

Basically, 'regular' LCD monitors use one or two cold cathode lamps for backlighting - these tend to be somewhat bigger and use more power. LEDs tend to provide brighter, more even lighting, and probably should last longer (They're simpler, needing no inverter, and use a lot of smaller lamps rather than one large one) .Taking into account that you can adjust and display brightness, the LED is probably a better choice. Just remember to adjust settings to your liking with both the monitor, and the system - for example tweaking cleartype.
