Question about U2410 calibration

I have a Dell U2410 and a Colormunki Display.

After calibration I notice the display is dimmer, which is what I'd expect. My question is; if I go into my monitor settings, the brightness is still set on 100. Does that sound correct?

Does the calibration software target luminance or do you need to manually adjust it? I'm also not familiar with the monitor, but if it's a software calibration then I'd expect you'd need to (possibly manually) drop brightness to around 15% to get somewhere between 80 to 110 cd/m^2. It should look disturbingly dim compared to 100% brightness.

100% brightness is 400cd/m^2 for this monitor which four times higher than it should be for image editing. Not sure, but I don't think the brightness control is linear.

My Eye-One Display 2 requires that I adjust the brightness (luminance) and contrast manually with assistance prior to starting the automated calibration run.

There are two ways that a monitor can be made darker; The hardware method in which the backlight is dimmed or the software method in which the profile's tonal response curve is pushed way over to the right. If you don't do the first, the calibrator will do the second, but the hardware solution is the better one, better than a truncated TRC. That is why most software packages will request that you manually reduce brightness first, before the calibration measurements are made. You do most of the work and then the calibrator completes the job.

Ah, that's excellent info!
