Damn Rube, another zinger that fell flat at my feet

Professional photographers are 110% OCD about color, luminance and sharpness on their displays. Getting natural skin tones is tough. Making sure that the brightness and color of what you see on the screen is the same as whats on the print takes skill and the right equipment.
Even with proper calibration there is no way you can trust what you see on a Dell laptop's screen for final editing. All of them are 6 bit panels, and you have to have an 8 bit LCD to edit. Further than that you have to have an the right type of LCD panel. The 2407 with its Samsung PVA panel has great grey transitions, but it is a little bright overall. If you calibrate it once evey couple of months you are good to go.
One thing you also have to remember is that pro photographers have really only had decent digital SLR bodies since Canon came out with the D30 (not 30D) in 2000. Back then people went for 17 - 21" CRT monitors that they had to calibrate every week because of tube drift. My guess is that most people running VGA were doing so at less than 1600x1200. Running VGA on a 1920x1200 LCD will work and gets you around the speedy drift of CRTs, but you still have to deal with drifts from converting from Digital to analog VGA, then back to Digital. You also have to deal with NOT having 1 to 1 pixel representation on VGA. That lack of 1 to 1 is one of the reasons VGA is less sharp.
I know that a lot of graphic designers with high end monitors back in the 90's would use BNC connectors because they could not live with VGA 10 years ago. Sorry to shoot down your 10 years of living with VGA statement. Go read a book.
