I recently did a clean install of Win XP Pro on my desktop. I'm using an e-machines CRT for my monitor. I plan to use this machine for photo editing. But before I do, I would like to know the truly proper way to calibrate this monitor. When following a monitor calibration guide (which are everywhere on the net) should I use the built in contrast/brightness controls on the CRT or the desktop color settings in the Nvidia Control Panel software that came with my motherboard. Or should I use both? I have an Asrock N68PV-GS motherboard with GeForce 7050 onboard video graphics. Please let me know if you need any additional info.
