Can the Wacom Cintiq 16 DTK1660K0A be powered by USB? I know the Wacom One can be, as the AC adapter can be removed. Wacom’s website only mentions that the Cintiq Pro 16 cannot be USB powered.
As far as I can tell, the Wacom Cintiq 16 should work fine under Linux. Is anyone able to confirm?
Thank you!
Three 3 in 1 cable carries 3 signals: hid interface for the drawing capability, power, and hdmi signal.
I have seen some tablets that uses a single usb c cable: https://www.huion.com/pen_display/Kamvas/kamvas-13.html but it is rare for bigger pen displays. Without usb power delivery the usb is limited to just 5w output and the display will be too dark to use most of the time if works at all. Some tablet will fallback to lower brightness or with the panel turned off but that varies from vendors to vendors
Unless the product page specifically calls out for usb c to usb c cable you can be pretty sure that it uses 3 in 1 cables.
The device you mentioned has been selling for 2 years now and the latest distro should work out of the box, otherwise this thread might be useful.

I don’t understand; I intend to plug it in, I am just wondering if the power cable is a USB cable or if it is a electrical cord?
The link you posted led me to here:
Which answers my question. The Cintiq 16 is supported by kernel 4.10 and later.
Thank you for your help!

The cable has three ends, you need to plug them all in to function. In cables like this the USB end only carries data signal.
Now I understand, thank you!
