I've got a new laptop that came with a 4k UHD screen. The GUI on QGIS doesn't scale well making most of the menu elements too small to easily see.
Is there a way to change the scale of the gui?

Find the qgis executable. If installed with OSGeo installer, it is in C:\OSGeo4W64\bin.
Right click on qgis-bin.exe and choose Properties.
Select the 'Compatibility' tab (the second tab).
Select 'Change high DPI settings' at the bottom of the tab.
Check 'Override high DPI scaling behavior' at the bottom.
Select 'System (Enhanced)' from the drop down.
Now, Start the application.

It's an ongoing process to update the whole user interface to be compatible with hidpi screens. Basically it boils down to revisiting each icon which is not adapted and redo it. The last couple of days many icons have been updated.
Please try a recent nightly build (master version, to become 2.16 soon) and report issues for icons which are still not updated.

As @Dave Pitman points out in his answer, that a user, Stu Smith, got the manifest hack to work.
I actually got it to work too. Follow the instructions using the link:

Once the manifest.txt file is downloaded, copy it to the QGIS bin folder. In my case:
and rename it to 'qgis-bin.exe.manifest'.
Additionally, you'll need to ensure display scaling is disabled.
To do this, you'll need a shortcut to 'QGIS Desktop', for example, by pinning it to the Windows taskbar.
Right click the QGIS icon, then right click 'QGIS Desktop 2.18.3' in my case, and select 'Properties'.
Click the 'Compatibility' tab, and uncheck 'Disable display scaling on high DPI settings'.
There's a minor niggle that the text and icons are not as sharp as they would be otherwise, apart from that the hack works pretty well.
Update: For the Windows 10 Creators update, in the 'Compatibility' tab, check 'Override high DPI scaling behaviour. Scaling performed by:', and then select 'System' from the drop-down menu.
