The visible spectrum is a rather narrow portion of electromagnetic spectrum. Roughly speaking ‘perfect’ human eyesight can perceive wave lengths from 400 to 700nm range. To create a standard that covers this range the international Commission on Illumination (aka ‘CIE’) created the 1931 color space that we still use to this day as the ‘gold standard’. The roughly triangular colored shape in the image below represents this ‘perfect’ color space. The smaller ‘inner’ triangle represents the sRGB color space standard and is the bare minimum any modern monitor should be able to display.
Default Red, Green Blue output
In a perfect world every monitor would accurately blend RGB levels optimally, and provide a score of 100/100/100. After all, a monitor blends these three colors to create the image displayed on your monitor. Unfortunately, not every monitor is tested at the factor and ‘color calibrated’. We consider a variance of 2 (99-101) to be very good, a variance of 4 (98 – 102) to be good enough, and anything beyond this requiring color adjustment before the monitor is really ready to be used.
Power Consumption
We have included two numbers for power consumption. Maximum is taken with the monitor to set to 100 percent brightness and 100 percent contrast, while ‘calibrated’ is taken at 120cd/m2 after color calibration.
