I'm a web developer, and for a hobby I take photos and edit them on my computer. I've found that sometimes I miss stuff on my own monitor that are apparent on other monitors (aliased edges that didn't appear on my screen, for example.)
What tools/methods can I use to get the optimal settings for my computer?
Also, is it common for VGA (DE-15) cables to show less color detail than a DVI cable? I recently got a new monitor at work and it turned out that I couldn't see the difference between white and any color with RGB values above 230 or so until I switched to a DVI cable.
