I am about to calibrate a new Dell 2707WFP LCD moniter with SpyderPro
2.2. If I use the DVI connection, I do not have access to the front
controls on the moniter such as brightness and contrast. I only have
access to these when I use the analog connection. Since I want to
calibrate the moniter with my SpyderPro 2.2, am I better using the
analog or DVI connection?
I usually explain this in terms of someone who has always had a standard transmission being dissapointed with a new car with an automatic transmission, since it no longer has a shifter, clutch, etc...
Using analog to gain controls not available digitally does not necessarily improve your results, and lacks all the virtues of digital video. There aren't actually hardware adjustments for brightness or contrast in your LCD anyways, so most of the value of adjusting them is lost, since its applying the adjustments at the videocard, not to the display. The one that is actually a hardware control is backlight. So I'd suggest hooking up digitally, and adjusting your white luminance via the backlight control, and leaving it at that. You aren't loosing much in the way of real hardware controls, and you get direct digital color.
