Depending on what you use your monitor for color gamut and/or color accuracy may be very important. If you are a serious photographer you will fall in this category. Anyway, there is a on-line test that can measure the color gamut (spread or separation of color/hues) on your monitor. Many laptop monitors have limited 6-but gamut and the average desktop monitor, like the current iMac, is 8-bit. High end monitors like LaCie or Eizo offer large gamut and 10, 12 and even 14-bit LUT (look up tables) which allow for great color separation.

Below is a link to a test anyone can take to measure the color gamut. I thought it would be useful to start a thread that we can use to share information on various monitors to make the purchase decision a little easier. A perfect score is 0 and the test is simple for those with high-end monitors. It is tricky for average monitors so take your time. This test will only measure your monitors abibility to separate colors, not color accuracy!!!

Please state the following after you have taken this test:
http://www.xrite.com/custom_page.aspx?PageID=77

1) Monitor Tested
2) Was the monitor calibrated and if so how?
3) Score
 
1) 20" iMac Core Duo, (early 2006, first intel iMac, matte screen)
2) Calibrated with Spyder3 Pro (one with ambient light sensor)
3) Score of 0. I am male in the 20-29 age bracket. Supposedly this means I have perfect colour vision!

Unfortunately this isn't going to tell you conclusively whether your monitor is accurate or not as we are using different measuring devices to measure each monitor (i.e. our eyes) - better would be to post your ColorSync profile for your calibrated monitor vs a standard, say sRGB.

1) 27 inch iMac i7
2) calibrated by my own eye
3) score of 3

Ooh I shoulda used digital color meter :D
 
I should have listed mine

1) Samsung 215tw (S-PVA)
2) Calibrated with Eye-One Display 2 sensor and software
3) Score 18 (age 51)

Those iMac scores are impressive.
 
I wasn't particularly optimistic about the imac scores but with the low scores of the few that responded was enough for me to place and order for a 27" imac from the refurb store. I should have it by this time next week - I just hope that I don't have any trouble with yellow :)

The colours on the iMac are excellent. The only problem is getting one that has a perfect screen.
 
1) 23" ADC Cinema Display
2) Default calibration (I'm lazy)
3) Score of 0 (I'm 23)
 
That was fun. Did it on not Yellow affected area of screen.

Thanks. I did do a quick search but I guess I was not thorough. However, that thread did not ask people to state which monitor was used and that is important since this is more than just an eye test it is also a monitor test. The person that told me about this scored a 20 on one monitor with difficulty and got a score of '0' with not effort at all on a his new NEC 2690. Same person/eyes but different monitors/score.

Fingers and toes are crossed for when my new iMac arrives. I am hoping it is a good one since it is a refurb and therefore likely to have had this problem and had it fixed. But, we shall see - I mean that literally :)

Forget the above as this is a complete misinterpretation of the test. Your monitor can make it easier to do the test when it is properly calibrated and that's about all it has to do with this test. This test is not about your monitor whatsoever, this test is about YOU. This is a colour vision deficiency test not a "how-well-does-your-monitor-display-stuff" test!!

This is very easy to understand because it's exactly what the caption mentions:
FACT: 1 out of 255 women and 1 out of 12 men have some form of color vision deficiency.
Take the online color challenge, based on the official FM100 Hue Test by X-Rite.

So for people who scored 0, congrats, you most likely do not have a colour vision deficiency. For those who didn't score a 0...you might have one (doesn't mean it's a bad thing btw).

Thank you.

And it is the same test as the one in the other tread.
No need to create a new tread just for this extra info. on what monitor is used.
If OP just read trough the other tread it would have been clear that most people have stated what monitor is used.
 
27" iMac i7 Quad Core
Based on your information, below is how your score compares to those of others with similar demographic information.

Invalid thread

For those that stumble upon this thread the site mentioned is not for testing monitor calibration but for testing the users ability to differentiate colors. While calibrating your monitor is not required I am sure it helps. If you score less than perfect you should see an eye doctor to confirm your color vision if you are in a business where color is critical. Tests similar to this are used in the prepress industry to test potential employees. Only 25% of males score 100%. Women have a higher percentage.
 
Are you experiencing any display issues on your monitor? Use these colors to test your screen and make sure everything looks as it should. pure black, white, red, green, blue, cyan, magenta, yellow, and grey colors in a variety of sizes and formats to help you quickly identify potential issues with color reproduction between your display and the content you're viewing. Pure colors to test screen​
