I recently bought a Spyder X. I have a Dell XPS 9370 laptop with a
powered Dell TB16 Thunderbolt dock. The dock has two 24" LED screens
attached. If I use a USB A to C convertor and plug the Spyder into
the laptop directly, the software can find it. If I plug the Spyder
into the dock, which is much more convenient, I cannot select the
Spyder as a calibration source, it keeps resetting to "none".
I have queried this with Datacolor and received the replies, "The
dock is the issue - Be sure not to connect your Spyder through a USB
hub or extension cord; only connect directly to your computer" and
"Fact is, that the SpyderX hardware must be directly connected to the
USB-port of the computer on which the SpyderX software is installed.
Furthermore, the computer display(s) you want to ICC calibrate with
the Spyder need to be directly connected to the computers graphics
card (no docking station, no switch, no connectors, no hub, no
Does this make sense? My laptop has Intel UHD Graphics 620. This
supports up to three displays. My understanding is that the
Thunderbolt dock is simply taking two digital streams from the
laptop's internal graphics "card" and transferring them to two
DisplayPort connectors on the dock. If displays could only be
connected directly to the laptop, that would immediately rule many
Apple laptops out of supporting multiple displays.
In any case, I don't see why the way the displays are attached
relates to how the Spyder has to be connected. Surely the USB data
stream is just extended by using the dock. Nothing else that I use
will work only when directly connected to the laptop. That includes
mouse, keyboard, external disk, camera, DVD writer, bar code scanner,
printer etc. It seems to me that the Spyder, or its software, is the
issue - not the dock.
