Display Calibration 101: Step-By-Step With Datacolor's Spyder4Elite

Spyder4Elite How-To: Wrapping Up

On the final screen is a CIE chart that displays the calibrated result. You can toggle between three different gamuts (sRGB, NTSC, and AdobeRGB) to see how your display stacks up.

If you have multiple profiles saved, you can plot up to two of them at a time on the same CIE chart in order to compare their results.

The View Info button opens a new window displaying detailed Brightness, White Point, Primaries, DeltaE, and Gamma measurements.

The Print Report button combines the CIE chart and contents of the View Info window on a single page.

We’d like to see additional graphs for white balance and gamma added to this window; perhaps a future version will include them. However, for those interested in seeing full measurements, there are individual tests available when you click the Advanced Analysis button.

Advanced Analysis

From here, you can perform the Gamut, Tone Response (gamma), Brightness and Contrast, White Point At Different OSD Settings, Screen Uniformity, and Color Accuracy tests seen in our laptop reviews. All results are displayed in a slick printable graphs or tables. These kinds of graphs make it easy to see just what your display is doing. Below are the results of the Tone Response (gamma) test performed on our AOC I2757FH.

The upper Tone Response chart shows the reference in blue and the actual measurement in black. In the lower Gray Ramp graph, the color temp is plotted on the X axis and the signal level, in percent, on the Y axis. This is our AOC I2757FH again, and you can see it needs a bit of tweaking in the grayscale department and the white balance is running just a little towards blue. But we're getting a little ahead of ourselves, we'll explain what all that means next time, when we delve into the principles of color science behind calibration.

    I still don't understand why we have to buy a $250 device just to get a proper picture on our screens. Why are they not factory calibrated? After all, in these days, the input is digital, so the display data should be 1-to-1 identical to (for example) game RGB data... I'm sure I'm wrong somehow, but about what?

    That was actually a genuinely interesting article! Good work Tom's.

    The problem is twofold:

    Variance in the panels. Each panel would need to be calibrated individually adding time and cost

    The WOW factor. Many manufacturers will ship monitors with the saturation set too high so when you fist set it up it gives you the wow factor. I believe. This second one might not be 100% true and more of a showroom trick.

    A great article, a good introduction on an often overlooked aspect of the PC setup. Every screen I have ever bought has had a ridiculously high brightness out of the box, which I suppose could be put down to a 'Wow factor' for sure... The kit is expensive though, but if it is going to make every screen you own 20% better and last for 5 years it starts to look like a good investment.

    I was wondering if the re-calibration of the cheaper units (such as the Spyder) can be done with the Spyder itself or do you need specialist kit?

    It is IMO ridiculous to suggest the spending of near the cost of a monitor to calibrate it.
    There are several Blu-ray Discs (Disney World of Wonder for example) that will achieve 80%+ of the levels of calibration for 10% of the cost.
    Was the author sponsored by DataColor or, just wildly out of touch?

    How does a blu-ray calibrate a screen then?

    Is short (for the example I mentioned) , you get several display patterns shown and adjust your screen until they display as they should. You will need to do this a few times for each as some will impact others (you would have to with the Datacolor as well unless it can adjust your monitor automatically afaik). The colours are adjusted the same way but with a filter used by you to help 'understand' the data.

    Hopefully that will help

    So do you have like a physical card to compare with what's on screen?

    No, the only physical item (other than the disc) is a blue tinted filter which is used for one of the several tests.
    Brightness (as an example) displays a test strip and you adjust the brightness until your screen shows certain details but not others (as instructed by the previous 'chapter' of the 'film').
    There are several levels of testing and reading the review I linked will give you more of an idea.

    I did the setup for TV, projector setup (Datacolor products won't work on projectors as the device blocks the very image you need to measure) and my monitor. The projector wasnt far out and made a small difference, my monitor and TV were 'miles' out and the tuning with the disc worked wonders :)

    It's very much subjective still, rather than absolute. While I agree for most people this is pointless, if you need it calibrated you need it done properly. I wouldn't surprised if you could rent one of these if you looked hard enough.
  • timbozero
    It is not at all subjective, you need to use it to realise that it is 'absolute' but, it is not as accurate as digital metering (only close to).

    If you're using your eyes, then it is subjective. You can't say that everyone's eyes are the same, 20/20 or not.
  • timbozero
    *sigh* Think how you will , I am not here to change your mind.

    The brightness test (for example) is done with a graduated display thus :-
    http://static.highdefview.com/wp-content/uploads/review/wow/wow_brightness_thumb.jpg.pagespeed.ce.JIxKCdd3ek.jpg
    There is only 1 point on the brightness adjustment where the correct graduation will match and the only 'downside' (which you could even remotely call subjective) is that it will not be spot on (as a digital meter might be).

    There is another for contrast etc., etc., etc.. Once they are all completed .....

    Ah hell, try it or don't. It made a massive difference to my cinema room and for only 25$ which is a bargain compared to the digital meter (which was my initial point, that it's overkill to buy a meter)

    Peace, Out :)

    We'll agree to disagree.

    Very interesting and much needed article, keep up the good work!

    But there is one thing that comes in mind, about the licence of the S/W.
    Is it possible to install the S/W and the colorimeter on more than one computer, or is it locked to the first computer once one has entered the activation code?

    Because I have several computers at home and really would like to use the equipment to do this calibration on them all.

    I assume that there should not be a problem to calibrate two monitors on the same computer?

    Best Regards from Sweden.
