Power Consumption

With the U2711 Dell opted for a CCFL backlight to deliver a wider color gamut. Apple moved to LED to reduce the size of the display's chassis and cut power consumption. Even while charging a MacBook Pro and running at full brightness the 27-inch LED Cinema Display never got more than warm. Part of this is due to the vent in the back of the display:

The display is also just generally power efficient:

LCD Power Draw (Kill-A-Watt)

The 27-inch LED Cinema Display tops out at 98W at full brightness, only saving about 14W compared to my old 30. The power efficiency is greatly improved however. At 98W you get a brighter display than almost anything on the list. Note that this is peak power consumption without a notebook attached to the MagSafe port. I plugged a 2010 15-inch MacBook Pro that was nearly dead and measured a max power draw of 166W at the wall for the display + charging the notebook.

LCD Power Draw (Kill-A-Watt)

At the lowest brightness setting the new Cinema Display sips power, 23W to be exact. You can even go up to 50% brightness (~100 nits) and never pull more than 40W at the wall.

    Does the system fonts on this appear too small like the iMac 27 inch? I have the Apple 24 inch LED now and love it since I can see the font. I want to get the new 27 inch but if it's like the iMac 27 inch, I will pass.

    Please confirm.

    I guess the Apple premium (perhaps excepting accessories) has really gone away over the years. Now all the major manufacturers have the same business model - a little distinctive design then outsource to Asia - so prices come back a wash. I remember when Apple wanted $1-2k more for their 30" monitor than anyone else. Now this comes in cheaper than the Dell U2711. Reply

    I don't understand why the manufacturers are pushing for such high density displays - for me, 1920 x 1200 at 27 inches is the ideal resolution. Mostly because of font sizes and such, 2560 x 1440 just makes things seem too dang small.

    I don't known if it's a factor of getting old, but most people I work with seem to think the same.

    It's because things just look better at a higher DPI. If the fonts are too small, change the font size. Windows 7 has great support for this. My old 17" CRT (I'm too picky to use a TN panel LCD, and too cheap to spend $1000 on a nice IPS LCD) is 130dpi and things just look so much clearer when I run Windows at 125% font size. The number of apps that don't recognize the setting is much smaller than it used to be. Pretty much all apps that were released in the past 5 years support high DPI.

    I can actually see large differences at 12pt between fonts like Arial, Cambria, and Verdana, where on 96dpi they were very slightly different.

    I have a high-dpi display, and can't use any desktops, because they all have crap DPI.

    I wish someone would make a 30 inch 2560 x 1600 TN so I could actually afford one. Im surprised Asus or Alienware or one of those doesn't get with some OEM and make a $500 30 inch TN for us gamers who don't need all the perfect viewing angles/colors etc......

    I am ready for more rez (currently on 19x12) but just can't stomach the 10 benjamins to get to 25x16

    I disagree, strongly.

    Your display is just as important as what video card you have driving it, simply because if you're in dark corridors, and the viewing angle makes more of a difference than the video card, then the rendered picture is worthless. Likewise, vibrant colors tend to get a faster response from the brain than colors that are washed out and leave the image ambiguous without looking at it for a few seconds.

    I've got two solutions:
    1) Go with a projector. Variable screen size, plus a low resolution to keep frames high.
    2) Stick with the stuff in your price range.

    It's this kind of demand that gets us huge, high resolution screens, with images worse than current solutions.

    I'm disappointed with this offering from Apple, because it really is all-glitz and not much substance. As a consumer, I expect to pay a price and get a superior product. And I acknowledge that the price is ridiculous, but at least I don't have to play the "mixed bag" game. I am not wow'ed by the ability to pay a lower price and get something "like good". That's not Apple-like at all.

    Second it. The price of 30" has been frozen at ~$1200 level for what, 3 years already? Those who claim that the cost of IPS panel is high, should look no further than LCD TVs, which prices steadily declined in all size categories. Today one can buy two good-enough 46" TVs (they are IPS!) for a price of one 30" monitor. Reply

    It's harder to make more pixels perfect so some of the cost is found there but it's also a question of to little a market so that mass production effects are limited.

    To many people are simply content with what they got and the majority looks at screen size vs. prices and then get the terrible TN panels. It's like in the old days with CRT's where most people ran them at 60 Hz because that was Windows default not knowing good screens could do so much better.
  • Dustin Sklavos - Tuesday, September 28, 2010 - link

    Disagree. TN technology starts to really hit limitations at around 24", when you get bigger than that you start to lose uniformity and the sweet spot for viewing gets that much harder to find. A 30" TN panel would look awful. Reply
