How much better is LED monitor

I am thinking of returning my h243h acer because the brightness on 25 or lower is still incredibly bright and in my dimly lit living room it glows brightly. With the lights out even at this low brightness I am looking at dark gray.
So I was thinking of getting a Dell LED 24" which would be about $60 more. Is that gonna be worth it?
 
Its hard to say. I have a samsung XL2370, which is an LED backlight TN panel. It looks nice, but its hard to say how good the contrast ratio really is. Its really bright, I had to turn the brightness down. That being said, I know the thing with LED backlighting is that it can be switched off completely, so dark colours should come out darker. Reading reviews on them is probably the best thing.

Yes
 
I have been reading reviews. Man they don't help. Some say that they are better than cfl others say they are way to bright and wash out colors. Most say there isn't a huge diff. *sigh*
 
Why not go to a brick and mortar store such as Best Buy and visually compare them yourself?

Well that's probably cus many of the LED monitors are just crappy monitors with LED's thrown on as a selling point.
 
led has nothing to do with image quality when dimmed😛 image quality is a matter of the panel quality. led is just a backlight. some nicer lcds used regular backlights and were high color gamut. unless its RGB led its just a little power savings is all.
 
I think hes referring to backlight bleed, in which case LED would definitely have an effect, since it can be more completely turned off. But yeah, it doesnt affect colour space or anything.
 
Do current LED monitors actually turn off the backlight when dispalying an all black screen? Cause that is the issue I have with my current setup. Brightness at 10 and it is still super bright in a dark room and black screens look dark grey.

Have you used any software or hardware calibration methods on your screen?
 
Yeah.. screen itself on non black looks fine. It is just that on all black it is almost a dark grey or a dark blue. My living room is very low light. brightness is all the way down to 10. Lights off and it is like a dark grey spotlight.

So few desktop LCDs are LED backlit or IPS. It is like cheap wins and I feel technology is really moving damn slow when it comes to desktop LCDs. There are tons of TV that are LED backlit but I can't name a sing desktop LCD that is.

almost no chance, no mainstream desktop screens i know of use local dimming, most are edge backlights just like the old tube ones were. local dimming is more expensive, uses more power and in dodgy implimentations deliver artifacts because knowing when to dim is hard. led resolution aka number of zones of backlight depends on price, and you aren't going to get any resolution worth noting for cheap. the only real good one i know of are tvs, the really expensive top of the line sonys that deliver rgb led backlights. those are sweet. if it claims to save power its almost garranteed not to use zone backlight/local dimming as that tech isn't thrifty.
 
so LEDs are just as bright as current ccfls?
is there anyway to get a dark screen in a dim room?
cause here it is 7 in the morning. curtains closed, one light on and my blacks at 10 look dark blue. Well blue is not really the right word. It just doesn't look black like my bezel or even black like when it is in sleep mode. It has a kinda bluish look(only way I can describe it.
Now granted when anything else is there to contrast against it then it does look more black, but still I want better.
 
Most references say LEDs are brighter than CCFLs. Dimming the monitor with LED backlight is not an easy thing to do. This article is pretty good in explaining some of the pros and cons.

Brightness control of LEDs is not an easy thing:

Maybe a polarized screen would darken it a bit?

Turning up the contrast might make the blacks a little more black. If you've tried all the adjustments and still not happy with the blacks then I suppose it's just not a great monitor... poor black levels. My blacks look pretty darn good here on an NEC 20WMGX2 but it does help that it's a glossy screen. That antiglare coating is not good for your blacks.

cnet link is probably wrong on this point.

I didn't see any marketing material from a laptop manufacturer that mentioned the expected lifespan of LEDs vs. CCFLs. But, a company that manufacturers LEDs did claim they last longer than CCFLs. When I ran this by Alfred, he said:

The difference is probably not important, but yes, CCFLs don't last as long. Even more significant is that their output decreases over time. End of life is when they are half as bright. LEDs are solid state devices, and "fall off the cliff" in failure mode; in other words, they keep working like when they were new until they stop working. Most people aren't going to keep their notebooks long enough for the CCFL aging to show any difference.
Market Share"
i think leds fade as well.
 
One LED advantage has not been mentioned . . . that the screens can be made thinner and lighter with LED than with CCFL.

Oroo Oroo brings up good points. With large TVs, LEDs seem to be worth the extra cost in terms of thickness, weight, and "greenness" (energy conservation.) Less so with notebooks - but, they should result in measurably longer battery life if that is of any importance. With me it is not - I rarely use the battery even when traveling.
