Regarding the Power Off problems - no idea, sorry.
Regarding bit depth I have a few:
Windows or Mac?
What graphics adapter do you have? Does it support 10bit output?
Is the Monitor connected via Display Port? Neither Thunderbolt nor HDMI does support 10bit, afaik.
Is the monitor a real 10bit display or does it use 8-bit+FRC (Frame Rate Control)?

"It is also worth mentioning there are some monitors advertised as offering 10-bit color output, but are not true 10-bit, but rather 8-bit+FRC. 8-bit+FRC (Frame Rate Control) monitors are 8-bit monitors that essentially fake the output of a 10-bit monitor by flashing two colors quickly to give the illusion of the color that should be displayed if it were a true 10-bit monitor. For example if the color that should be displayed on the 10-bit monitor is number 101 in the Look Up Table (LUT), and an 8-bit monitor is only capable of displaying color number 100, or 104, an 8-bit+FRC monitor would flash the color number 100 and number 104 quickly enough that in theory one should not notice the flashing. It's goal is to fake the human eye into thinking it is really color number 101. To do this the 8-bit+FRC monitor would flash between color number 100 for 75% of the time, and color 104 for 25% of the time, to give the illusion of color number 101, similar to how rapid succession still shots work to give the illusion of motion when displayed one after the other quickly enough. If color 102 needed to be displayed, an 8-bit+FRC monitor would flash between displaying color number 100 for 50% of the time, and color number 104 for 50% of the time to give the illusion of color 102, as opposed to a true 10-bit monitor which would be able to simply display color number 102 from the LUT."

The True Color Finder software only works with a hardware calibrator device if you want to recalibrate, I think.
If you have not purchased one of those which are supported by the software it is pretty useless.
But i could be entirely wrong about that.
Using adapterslike dvi-hdmi or dvi to display port may cause issues.
I think the USB Port simply works as a hub.
