Spyder calabration effected by M8 at well

[AlbanRampon]

Hello John,

I have a few questions to better understand and because I'm not familiar with Datacolor.
Would you please be able to attach log files as described in my forum post signature?

Does your wife uses the Datacolor external tool to calibrate the monitor colours?
If so, then this is because this feature is not yet supported through DisplayLink chips. We take content to display directly from the graphics card and we don't (can't) do any colour correction. This feature is my roadmap once we have rolled out DDC/CI on all recent products (products which can do it): this is to use the computer to remote change brightness/contrast. Colour correction (like in f.lux) is more complex as we need to modify the image we get from the graphics card, something we don't have support for at the moment.

About graphics card selection, it depends on the generation and NVidia driver.
Do you base your observation based on performance or from a tool? If from performance, there is a bug that Microsoft has fixed (in Windows build 14906, we verified in 14909). The graphics card is erroneously put to sleep when no direct monitor is connected. We have a couple of companies 300 times my company size pushing for the fix to be rolled out through servicing (= a Windows Update to the current Windows version) instead of waiting until the next version of Windows. Microsoft is being very reasonable about this and I believe it will be done!

If from a tool, you might have a way to force the Intel graphics off so it uses the higher performance one. The log files might give me a bit more info about what is possible.

Kind regards,
Alban
