Which means you can use it to do this...
...or this! Microsoft calls this Continuum, and it means that you can connect the phone to a monitor or TV screen to see your phone contents on a larger screen -- like a photo slideshow or a Word document you're working on.
So long as you have a compatible dongle, or an aftermarket dock that uses a bunch of cables.
Three of them for the dock, minimum, including an HDMI cable and two USB-C cables (one connecting the phone to the dock, and another going from the dock to a power outlet).
Here's a closer look at the type of HDMI dongle and the Microsoft Display Dock, which you'll have to buy separately if you want to use Continuum.
The dock has a bunch of connector ports on the back, for wired keyboards and mice, and the HDMI cable.
A closer look at the USB-C port where you connect the Lumia 950 phone.
You can also add wired or wireless keyboards to make typing (and composing longer documents) a lot easier than scrolling and typing on the phone to see your work on a monitor.
A mini tutorial gets you started with setup (but doesn't go far enough).
Here's the screen you get after connecting the phone to a TV screen using the Display Dock.
Tap the Start button to view and interact with your Start screen.
Documents and images fill the display. You can scroll, tap and navigate with your digits.
Here's the phone connected to the Display Dock.
The whole setup, including a wireless keyboard and mouse.
And here it is again with me. I used this setup to write much of the Lumia 950 review.
The Lumia 950 has other tricks, too, like biometric iris scanning to log you into the phone.
After it recognizes you, it winks!
The 20-megapixel camera utilizes a triple flash, which is meant to bring more natural color.
Here it is, all lit up.
The dedicated camera button takes shots and also triggers the camera to open when you double-click it.
The Lumia 950 has a newfangled USB-C type port for its connector. This is the wave of the future, but you may need to buy extra cables.
Although it's made of plastic and not more aspirational metal, you can remove the backing and battery.
A microSD card slot stacks above the SIM card tray.
Microsoft also spiffied up the look of the software inside. Just take a look at the new app store.
