Monitor Calibration

I assume that when one calibrates a monitor, the adjustments are actually on the computer video card, and not the monitor itself.

Is this correct?

Thanks in advance.

Basically, yes.

It loads the profile into the LUT (look up table) which I believe is part of the videocard driver software.

However, esp with hardware calibrator, this is all relative to any adjustments you made with the actual controls on your monitor. So if you use a colorimeter to calibrate you monitor, then afterwards adjust your monitor controls (or video card's software color controls, you've effectively ruined your calibration.) Important thing to remember is after you calibrate, leave all those other settings as they are be they on monitor or in display settings.)

Good points about not fiddling with the monitor after the calibration is done. In fact one of the steps in the calibration is to set the monitor to its default settings.

The reason I asked is because I use two computers with one monitor, and want to do two calibrations - just had to make sure that it is the video card settings that are adjusted during calibration and not the monitor.

My Samsung 910n monitor has it's ON/OFF button right next to the AUTO button. It's no surprise to anyone that I spend my life re calibrating because I've accidentally brushed the wrong button and the screens gone back to manufacturers default settings.

Anyone know a good way to disable this? Gaffer taping a metal guard over it might be one answer.

I'd use Gaffer tape

I didn't think the Samsung's Auto button reset the defaults, but instead changed it to calibrate for the input (still, a very bad thing to push if you want a calibrated monitor). Am I misunderstanding this button? Is it a nice, easy way to reset to default before I calibrate?
