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.

    At $999 this display is a bit overpriced.

    The low-end 27" iMac starts at $1699, featuring core i3 530, 4GB DDR3, Slim DVD, 1TB HDD, Radeon 5670 mounted on a notebook LGA1156 mobo.

    This hardware costs more than $470 on newegg, and the miniDP on the iMac can receive external video sources ( not to mention a possible hack to directly mount the iMac display externally).

    It would solve the main problem showed on the review: the self fulfilling prophecy that this display will only be used with Macs.

    The ideal Imac for hacking is the $1999 i5 + Radeon 5750. For another $1000 you get the very same display coupled with a valid mid range hardware all-in-one.

    Nice assumption but I doubt if it really is the case.

    What I recall is that when this S.Korean company introduced one of their IPS monitors in U.S a few years ago, they increased price about $300 (compared to S.Korean price) and people went crazy for it as it was considered very cheap compared to what was availbe in the market.

    Being interested in that, I did a breif research on IPS monitor market in S. Korea. What I found out is that a. there are so many feature packed IPS monitors b. they are much cheaper.

    Of course, LG - the IPS pannel maker - is a S. Korean coporation and that should explain the difference in market situation. However, what's interesting is that all other products that came from S. Korea - Samsung, LG, and even Hyundai automobiles- are cheaper in U.S than in S. Korea.

    After all, I couldn't figure out why IPS monitors are so much more expensive in U.S, not to mention lacking availability.

    P.S: After writing this, I did a simple search of IPS monitors on S. Korean electronics site. Keep it mind below are only a very small representation of hundereds of monitors in the S. Korean market. Last time when I did throughout research, it took me days and days.

    27" 2560 x 1440 IPS for $420 (sales tax included),
    26" 1920 x 1200 IPS for $500 (built-in HDTV tuner, speaker, PIP, D-SUB, HDMI, Component, DVI, RF Antenna, Tilt Swivel)
    30" 2560x1600 IPS for $620.

    Because this is a high-density IPS panel. It's really not too outrageous a price. Reply

    I'm more annoyed that they are going for 16:9 in even the highest-resolution computer displays. There is no reason for it, you're only losing desktop space. Reply

    Seeing how most applications have their palettes and settings in a column (either to the left or to the right of the main working space), I don't see how a wide ratio is a problem? Also, the ratio has nothing to do with the amount of pixels you can show—if you want higher pixel count, you want higher pixel count. If you want a ratio that's more of a square, you want that. If you just want a taller screen at the same width, go with one of the 30" ones. Reply

    I'll base my response on the fact that I am a computer gamer.

    For that kind of stuff, perhaps a LCD like this might be overkill... and considering the very slow response time of 12ms, might not be good at all, as you can find many TN panels around with a quarter or less response time (GTG) compared to that.

    Anyways, the vertical loss of pixels is an issue for several games, specially ones with customizable UIs, where you can move around windows and whatnot. MMOs come to mind. Those missing pixels, in this case, do make a big difference in your viewing area.

    Customizable UIs generally have the ability to put menus on the side, but true "gamers" would rely on a better keyboard than the onscreen interface.

    As xype has said, it's pixel count that you want. 27w" is the diagonal width, which would have the same vertical pixels as a 20-21" monitor at 4:3.

    BTW, if height is what you're after, you can rotate your monitor to 9:16 instead, it's only a matter of switching a setting in video preferences, but wider field of view is actually more important for gaming, especially in FPS, but also in MMORPGs.

    "but wider field of view is actually more important for gaming, especially in FPS"
    That is if you play "flat" FPS where everyone is at the same level, if you play FPS where players can be on top of buildings and what not the height becomes a very important factor, 16:10 is for me the best ratio available... also a 16:9 doesn't necessarily have a wider field of view than a 4:3, both could have the same horizontal resolution while the 4:3 would have a higher vertical one.
    I really don't get how the 16:9 is becoming the norm when its not a progress for gamers on the contrary...

    MS Word 2007 has the menu at the top of the screen, not to the side. Reply
