    Can anyone confirm that the Quadro 2000M on the W520 has multiple LUTs? I'd assume that there at at least two - one for the onboard display, and one for externals.

    Thanks!

    EDIT: Does the whole "optimus" thing muck with LUTs? IE, will icc info for the monitor be tossed every time it does its thing?

    it's a 6-bit display.   the hardware LUT doesn't change.   the ICC profile you choose is based on the display, not the GPU.

    if you calibrate your display and employ a special ICC profile, nothing will be "mucked" with when switching from discreet to integrated or vice versa.   once you set your ICC profile once per GPU using the windows color management control panel, it will be applied during any subsequent switch.

    Thank you! What about setting different icc profiles for external displays? Will that play cleanly as well?

    definitely.   WCM can assign an ICC of your choice to a specific device.   everything is handled in the 'color management' control panel.
