Sev, The following from the Datacolor website may be of some help: 'Please also keep in mind that older sensors are not able to deliver correct calibration results for displays with LED backlight (included in most MacBook Pros for the last 3 years), wide gamut displays or displays with a high-gloss surface. All these newer monitor technologies require a current technology sensor for proper calibration results. When a sensor adjusts Brightness, it is important to eliminate as much ambient light as possible. If you can't eliminate all the ambient light in your room, you can drape a dark cloth over the monitor and meter during the readings..'
Also of interest for members looking to buy a monitor for their Mac, or a new TV: Why is my picture so Red after using Spyder3TV? Solution When a display is shipped, it contain excessive amounts of Blue. This is to help it sell in the retail show room. However, this excessive Blue also makes people on screen appear cold, sick and ghastly. Some displays perform a "trick" where Red is added just to the portions of the gray scale where human flesh tones are located in order to make people look more alive and natural. This is also known as "Red Push". When we then optimize the image using Spyder3TV, and remove the excessive Blue to make the color more natural, the display may still be putting extra Red color into human flesh tones, making them TOO Red. What was previously a feature to help with sales is now a big problem in the home viewing environment. Without low-level hacking of your display's color decoder, this "Red Push" can not be fixed. Our recommendation for displays with Red Push is to turn the "Color" control down a few clicks until flesh tones are no longer overly saturated. We have provided a tool to assist you with this process in Spyder3TV. Click on the "Tools" menu and select "Color Verification" and you will be given instructions on how to use the Spyder3TV DVD Before and After test patterns to visually improve Red Push using human flesh tones as a guide.
