Power Consumption

Unsurprisingly, power consumption hasn't changed much in the past year. The Thunderbolt Display draws a bit less at its dimmest setting (likely just panel efficiency variance) and draws a bit more at max brightness:

While powering a 15-inch MacBook Pro and reading data from an attached Pegasus R6 (copying to a local SSD at around 200MB/s) I measured total power consumption for the display (max brightness) at 179.6W. That number could go up if the battery in the MBP was near empty and thus being charged at a higher rate.

    I wish someone would have the balls to step up and end this moronic glossy-screen fad.

    Glossy sucks in all lighting conditions. It doesn't matter where the illumination is coming from in the room, or even if there IS any. At the very least, the light from the monitor is going to illuminate YOU, putting your reflection over those supposedly "deep blacks" and "rich colors." Glossy screens work for one customer: the ninja in the closet.

    Going from a glossy screen to matte is like cleaning a filthy windshield: You wonder how you put up with it until that moment.

    At the risk of outing my secret identity, we closet Ninja's reject your claim!

    You and me both. I can tolerate it on my phone but my desktop or laptop are matte only.

    That and widescreen resolutions. Gimme a 4:3 high res matte screen anyday!

    Well, 16:9 with a 2560-pixel display still gives me 1440 pixels vertically, surpassed only by the 1600 in a 16:10 30" panel which costs double the price and significantly more than in any of the smaller resolutions.

    So I can live quite comfortably with my iMac 27" (same panel as in the TBD). "Suffering" on a very high level, so to speak. 8-)

    I've always felt like integrated monitors are a waste. The trouble with iMacs (and all All-in-Ones) is that you have to buy your monitor over and over again each time you buy a computer. So ~$800 of your computer's price went toward getting that 27" monitor, and when your computer dies, so does your display, and that money is lost.

    I've been using the same four high-end LCDs for my last three computers. I'll gladly spend $500/yr to ensure I have the latest and greatest computer without having to invest an additional dime in new displays.

    Macs generally life for many years. Actually, none of mine has ever "died". Even my first one from the early 1990s still works as on the first day.

    Plus, recent iMacs can serve as external monitors for other computers.

    Maybe you're just switching your computers a little frantically compared to most other people. My Macs have so far been in productive use for 5-6 years each and are just mostly collecting dust since retirement because I chose not to sell them to someone who could get good use out of them even after that.

    This is my first iMac. I'll see whether I'll keep it around as a monitor for its successor or if I'll just sell it off when the time comes. It's a pretty good concept, however, and it works very well in practice.

    I am stepping up (balls?) but to say you think you know what you are talking about but you are not.

    The thunderbolt display is a high end consumer display not a professional level display.
    Even the Dell 2711 is an entry professional monitor. Dell Is better suited for color correction and wide color gamut space but not the real broadcast deal.

    Where, where in a broadcast professional production environment would you even consider an Apple display? Maybe on press production for everyday news or on production studios for independent production on constrained budgets who don't depend on critical wide color gamut.

    80% of consumers and most professional not working on critical color correction don't care for mate screens. Glossy screens are better for watching a movie or content and in a controlled environment this is acceptable.

    "The thunderbolt display is a high end consumer display not a professional level display."
    "Where, where in a broadcast professional production environment would you even consider an Apple display?"

    If only there were professions OTHER than "broadcast professional"...
    But sadly we live in a world where every professional is a broadcast professional, and clearly Apple has screwed up in making a device that appeals to print workers, or programmers, or musicians. None of them, after all, are professionals...

    80% of people buying from Apple opted for glossy screens, this is a fact. The 20% that opted for mate screens still have the "optional antiglare display" in 15-17 Mac book Pros.

    Now, photographers, programers, musicians or other professional working with a "Mac Pro" have great options from other very well recognized vendors like LaCie, NEC, EIZO, HP, Dell and others.

    Apple as well as Dell have always been a cheap competitive alternative for higher end displays but never the best dedicated option for professionals who depend on the most accurate screen.

    The only ones abandoned are the casual, or entry level professionals that got use to working with Apple displays and some high end aficionados. That is true, but those could buy today a LaCie Monitor for around $950.

    I don't know, Apple could launch a mate display line whenever they see the opportunity, but they appear not seeing a good one in the present. Maybe they don't consider the number of professionals buying from Apple enough to produce more mate displays.

    Cheer up!
