iMac 24" panel; _discrete_ value comparison to other LM240WU2 panels

    I'm in the market for a new computer and the iMac is hanging in at the top of the list. The one thing holding it there now is the panel it uses (LG LM240WU2).

    My other top option is to build my own system (in that case I would use a Linux or some other *NIX OS). The main benefit to this is, well, everything but the monitor in comparison to the iMac.

    I'm also a sucker for value. I will, in reality, never require all that the iMac display offers with its viewing angles and color reproduction. Similarly, I will never need 6GB of RAM and a quad core processor that I would get if I built my own system. But I want those things because there's always great sweet-spot deals for the exhaustive shopper, and I get the warm fuzzies thinking I've gotten the greatest current value for the least input

    So here's the deal, there's a lot of great talk about the iMac's display being the same as that found in $1000 monitors like the NEC LCD2490WUXi. However, I want to know what that actual iMac display (not another monitor using the same [or similar] panel) is worth.

    I can't really find any conclusive data to help me answer this question. I've dug up stuff at tftcentral comparing all monitors using the LG LM240WU2 panel. There is of course the iMac, then NEC, and then a brand called Hazro. The first indication of discrete value is the response time:

    NEC LCD2490WUXi    8ms G2G	24"WS LG.Philips H-IPS A-TW Pol (LM240WU2)
    NEC LCD2490WUXi-BK 8ms G2G	24"WS LG.Philips H-IPS A-TW Pol (LM240WU2)
    Hazro HZ24W        5ms G2G	24"WS LG.Philips H-IPS (LM240WU2)
    Apple iMac 24"     12ms G2G	24"WS LG.Display H-IPS (LM240WU2-(SL)(B1))
    Apple Alu 24"      12ms G2G	24"WS LG.Display H-IPS (LM240WU2-(SL)(B1))
    the iMac has higher response times than either, this however isn't really conclusive, as these are inflatable by manufacturers.

    Next up is comparing the prices of the NEC and Hazro models. NEC models are $1000 dollars or more, while Hazro is about $675 (I actually only found a site listing its value in pounds, and had to convert). This is a wide value for two monitors using the same panel (and the one with greater response time is the cheaper!) Through googling I found a claim that the price, through apple, to replace the iMac screen is $750 (however, I think apple's prices for components are inflated, seeing as they charge $50 for 1GB of RAM). I also found a replacement panel on ebay (with 2 light scratches!) for $250. Only other price data is through mass sellers oriented towards industrial clients; however they only give prices through direct contact, and even then I would only get the price for buying 500 of them.

    Ultimately this data doesn't settle the question about what the real value of the iMac 24" panel is. It does however show the distinct possibility that the panel used by the iMac is not in every way equal to that in a $1000 NEC. That said, I do believe it is still a VERY nice panel, worth more than the average LCD monitor. I would really like at least a mildly accurate estimate of the value of this panel is.

    From what I've read, the panel used in the iMac lacks the A-TW polarizer found in the NEC. Otherwise, they're both H-IPS panels.

    Sounds like you're taking this cost/value mentality way too far, as you admit you'll never require all that the iMac display has to offer.

    that's beside the point. I can enjoy it without requiring it. Strictly speaking, we require very little...

    So I'm sorry for taking it too far, but ambiguities just bother me, I must find out what is the relationship between a panel, the third party value-added installer, and the end user.

    the NEC offering with that panel is $1000
    the Hazro one is $650

    Why is there such a big discrepancy when using the same panel? NEC and Hazro must add some value, some features, different technologies, maybe underlying algorithms that influence response time and input lag and other stuff. What does Apple actually add to the value of the LG LM240WU2? I'm sure the value of just the panel at retail is well under the panel installed in a display with some bells and whistles added. What if Apple doesn't really add any bells and whistles? Is the Apple display closer to the NEC monitor? or the Hazro monitor, or is it less than both?

    Why all the worries. Simply buy what suits you best. If you don't like the iMac screen get a NEC and some Linux box.

    I will not buy the NEC because it's $1000 :eek:
    I wouldn't buy the Hazro for six-fifty either

    the question is where does the value of the iMac screen fit in there? If I got a display of those calibers it would only be because I bought the iMac. Otherwise I wouldn't go over $250 for the monitor.

    Consider it this way: save for the screen I can price out every component of the iMac (and in fact already have). I have done this for comparison purposes to see how the value of buying an iMac stacks up to the value of building my own system. As I said, I don't need a high caliber monitor, I don't need a blazing fast system, I don't need to drink beer, I don't need to have sex... but I want to. I also want to know how the market value of an iMac compares to the market value of components I use to build my own system.

    For comparison's sake, in building a system versus buying an iMac, what is the value of the iMac display? I am quite sure it isn't that of the $1000 Nec, I'm thinking it probably isn't even up to the $650 Hazro using the same panel. But I don't know. I want to know just so I can make a solid comparison and see what is really the best value.

    The iMac 24-inch is a seriously good screen... even if you don't need it, it is definitely worth it. Trust me. I convinced a couple who are good friends of mine who are in their 50's to a) switch to Mac, then b) Upgrade to a 24-inch, as their original intention was to get the 20.

    Do they need a massive 24 inch screen? Hell no, all they use is internet and email. Do they love it and are glad they upgraded?


    Even if you don't explicitly need it, when you consider the extra RAM and hard drive you get in the base 24 inch model, it's a damn good upgrade. And the screen is amazing. If you buy an iMac, you must get the 24 inch one!

    thanks for the sales pitch

    can someone answer my question. I'm guessing no....

    A simple googling will tell you that a difference between the Hazro and the NEC is that Hazro does not feature SpectraView II (although they both have A-TW polarizer). The same panel used in the iMac does not have A-TW polarizer. Apple is able to purchase the panel in bulk for significantly cheaper so assigning a value to it is kind of moot.

    WHy hasn't the lp2475w been mentioned in this thread yet, it also uses the same panel and can be had for 500-600.

    You probably want to be aware that an uneven backlight was (and I think still is) a major issue with the iMac 24 screen. If your iMac has it, any solid color that goes across the screen (even a thin line) will look like the color is not completely solid, but rather has a gradient going across it.

    Personally, I am afflicted by it, and I have sent it for repair a second time in the hopes that it will go away. Here is a simulated image (from my other thread about this) showing what looks like on my iMac:

    That said, if you can get an iMac without a crappy backlight, then you are IMO getting a good deal.

    It has a slightly different model number LM240WU4.

    That just means its slightly revised in some way, probably extremely minor. Its still a 24 inch wuxga H-IPS screen.

    Yes, but someone asked why it wasn't included along with those with LM240WU2. Otherwise, the OP would have included LM240WU2, LM240WU4, LM240WU5 and LM240WU6, all of which are H-IPS.

    FYI: LM240WU1 is an S-IPS and LM240WU3 is a TN Film.

    There are several things you are completely missing here.

    You aren't just paying for the cost of the 24" iMac "screen" in comparison to other displays of the same caliber. You are paying a premium for the fact that the iMac display is integrated seamlessly to the computer, keeping the overall foot print low.

    Additionally this over priced screen includes an integrated camera, microphone and speakers.

    You can talk value all you want but at least compare products in the same category. Sheesh.
