CCFL Versus LED: Is There A Downside To Going Green?

Quality Tests: Samsung P2350

Now on to Samsung’s CCFL unit. Despite having the same default settings as the BX2350, this LED unit had us reaching for sunglasses the first time we fired it up, thanks to its relatively nuclear 315.5 cd/m2 luminance (0.3 cd/m2 minimum). While near the end of this roundup, the P2350 was actually the first monitor here on our bench, so we spent the most time experimenting with it. To illustrate the point of how there’s more than one way to calibrate a screen, here’s an Eye-One Match 3 summary for a calibration in which we nearly hit out 120 cd/m2 and 6500K goals. The standout point is that we left the blue channel at 100 and had to dial back the red to 39 and the green to 28.

See how far the blue line pulls away from the others? Now, here’s a calibration at 6500K with a 117.1 cd/m2 luminance. The color channels are dialed in at R60/G35/B50.

Better, right? Now, in the first calibration, we had the monitor set at a brightness of 36 and a contrast of 83. In the second, we kept the same contrast but notched back to 34 brightness. This was the configuration we finally settled on. We point all this out to illustrate how calibrations are not fixed; there’s no one right way. If you prefer, say, a brighter screen or stronger blues, you’ll want to prioritize those attributes at the outset and calibrate around them.

The P2350 flags a bit in overall luminance. It’s strongest at the center, with a moderate fall-off toward the left.

At these color settings, the P2350 turns in good results in our gamut test, showing a total volume of 897 107. The sRGB only escapes past the monitor’s capabilities in the violet range. For the curious, we left ColorThink Pro’s control UI showing in this screen capture.

The P2350 performs very well on accuracy in the grayscale tones. We see the usual bumps in blue inaccuracy, but overall, the Samsung CCFL remains true enough to average only a dE of 4.37.

  • How about doing this with IPS panels ? :>

  • In the "Wrapping It Up" section, perhaps you meant "LED" instead of "LCD"?

  • I am going to get such a monitor later this year. Imagine the leap from CRT to Led LCD.

  • I personally can't wait until the OLEDs manufacturing process becomes cheaper. Having seen Sony's new OLED displays at this year's NAB in Vegas, I can say they are VERY VERY impressive.

  • I know that I have been rocking a pair of Gateway FHD2400's for a few years now and love them as they meet all my needs and have never left me wanting

  • Ummm ... LED? They are all LCD :).

    "Ultimately, we’d pick LCD for media consumption, but we’d pick CCFL for editing work where detail and accuracy are paramount. LCD is more fun to watch; CCFL is more reliable."

  • Please substitute "LCD" with "LED" everywhere in the conclusion section!

  • Basically the differences are very dramatic right? I'm gonna sound like a hippie for this but I'd definitely go for the greener option. Just being polite for our future generation is all.

  • what g00b said. At the end you start saying LCD instead of LED, might confuse some poor soul.

  • May not be too relevant here considering that this article was based around image quality, but as a gamer, I'm still plenty satisfied with my trio of 25.5" Asus TN monitors. Yes, they bleed a bit of light around the edges and the colors may not be very accurate, but they handle fast moving images with no problems and only cost $750 for the set. And my favorite feature is the 16x10 aspect ratio, which is becoming quite hard to find these days; not sure why people are so willing to give up vertical screen space.

  • still does not beat a high quality CRT in image reproduction. size/weight/power are another thing.

  • if you check the evidence of osama's death on a ccfl screen you would discover he isn't really dead but it's just some random bearded dude they shot

  • X-Rite's iMatch software doesn't have a correction for LED backlighting. A colorimeter like i1 Display 2 is not a spectrophotometer and can't just measure any screen thrown at it. It requires corrections for LED and WCG-CCFL backlighting. Not sure how you can make far-going conclusions from these inaccurate measurements.

  • HOW ABOUT SOME CHEAP IPS SCREENS?

    It's starting to look bad- if you're spending 200+ dollars you might as well be buying a REAL screen instead of these ones.
    Even 40 more dollars buys you a screen FAR superior to these crappy TN panels.

    So why aren't they being reviewed?

  • It would be interesting to look at which LED lit panels use local dimming and which ones do not.

  • The funny thing in the opening of the article, it typically isn't the CFL that goes out in monitors. It is the power inverter, that powers the CFL. When I did dell repairs, it's funny they didn't let you just get the inverter to replace, you had to replace the whole panel.

    I image it's a leap off a cliff. You'll be dissapointed if you place them side by side. Well, depending on what your looking at, but try a dark image with detail in it,hint: you'll have to use the CRT to identify that image. Black crush sucks.

  • I was going to make the switch from a 24" VA panel to a newer LED panel (in which I tried two). The first was an Acer LED 23" and the blue hue this thing put off was gross. It didn't how much I calibrated it the colors were dull and the blue hue remained. The next LED I tried was the Samsung BX2450, 24"; the colors were better and the blue hue was less noticeable but it was still apparent (at least to me). I realize both are TN panels as well but I think I'll wait it out until a nice LED-IPS panel comes out for sale in the States.

  • @ masterbinky Have you looked at top quality IPS panel LCD's calibrated compared to a CRT lately? The HP LP2475w at work beats out an old NEC Multisync 22" CRT with darker blacks even though the whites are brighter, has very accurate colors after calibrating, and has zero black or white crush - every shade of extreme blacks and whites can be discerned on test images. If you don't want crap for LCD's you still have to spend over $500 for your monitor, no getting around it.
