The Eye-One is a device that lets you calibrate monitors (CRT, LCD, or notebooks). I decided to pick one up and calibrate every monitor in the house to see what kind of results I'd get.
The device itself looks like a suction cup (google pic) and there's a white plate used for measuring ambient light. I should add that it does not take ambient light into account in the color profile, though it does give you measurements of the brightness and temperature of the ambient light in your area.
The Eye-One Display 2 hooks up via a USB connection. This was very convenient since I have a USB hub right on my monitor. The circular black weight in the picture above attaches to the USB cord to keep the calibrator from moving. The color sensor cup hangs by the wire.
Some may find the installation confusing. There was a zip file containing drivers on the CD that you had to extract, and the software on the CD was outdated and unstable (v3.1). The latest Eye-One Match software (v3.6) works very well however, and even supports XP x64.
Upon starting the Eye-One Match program and selecting 'Monitor' you are presented with your 'target' calibration settings. For white point, I chose 6500K (daylight). Gamma was set at 2.2, the default for PC monitors. I left luminance at 120 nits, the recommended for LCDs.
Enough with the philosophy though. After you go through the whole process of adjusting contrast, brightness, and color channels on your monitor's OSD, how much difference does it make?
Prior to the calibration my 20WMGX2's settings were about 30 brightness and 50 contrast in the sRGB (6500K) preset (which isn't exactly 6500K). These settings were measured at about 250 nits, very bright for general usage. After, my settings ended up being 10.9% brightness, 82.0% contrast, and R:93.3%,G:88.2%,B:89.4%. This, coupled with the ICC profile it generated (which contains the gamma curve compensation), made the monitor absolutely beautiful. It was very easy on the eyes, and white looked consistent and pure without being overpowering. Black was 0.3 nits, a very respectable deep black. Even websites looked better: colors were more even and I found myself not fiddling with the brightness settings anymore depending on what I'm doing.
The calibration itself was quite tight.
NEC 20WMGX2
Color Temperature 6500K->6500K
Gamma 2.2->2.2
Luminance 120.0 cd/m2->120.6 cd/m2
deltaE2000 avg: 0.56
Needless to say I was very impressed with the results. Before I could say I had awesome colors, but now I can say they are even more accurate and comfortable. The gamma profile seals the deal by making fine adjustments that you yourself are unable to make on your monitor (or reliably on the video card). If you just had the brightness/contrast settings correct, color temperature could still be way off, and things would definitely looked washed out without proper gamma compensation. These are crucial to having impressive on-screen color reproduction, and only possible by using a colorimeter device like the Eye-One Display 2.
Measurements of other monitors:
Samsung 710t dE2000: 3.00
ViewSonic VP930b dE2000: 1.20
The 710t is a low-contrast LCD to begin with, so results were less impressive but it was easy on the eyes. The VP930b returned quite respectable colors after calibration. The colors were more precise, and it was a lot easier on the eyes than the monitor's preset SRGB mode. They recommend you recalibrate every 4 weeks to retain color accuracy. Even after a year it'd be much better than the defaults though.
