David R,
I agree, if you are printing your own images, then that control is important, but what gets sent to FAA's printer and how they print it, will also have slight variations, just the nature of the beast. For David K's purposes, his monitor is fine. Remember, buyers looking on their devices, phones,tablets,laptops and desktops, ALL have different "color" and most if not all, won't be accurate.
Anyone can take an image and go to a Sam's or Costco,etc. and get a "test" print and then see how it comes out, relative to their monitor. I have and IF I remember to turn off the "Auto Enhance" feature, the prints are perfect! Sam's larger prints, 11x14 are ALL done on the Epson system and are very accurate,so a test print that size will be fine to judge your monitor, for most people here,
Rich
