Apple released the LG UltraFine 4K Display and LG UltraFine 5K Display as the successor to its Thunderbolt Display but there are other USB Type-C based displays that should work with the MacBook Pro (Late 2016).
If you want to stay with LG, the LG 27 inch Class Ultra HD IPS 4K 27UD88-W Monitor (click here for pricing on Amazon) was the world's first 4K USB Type-C monitor.
Here are some other USB Type-C Displays out there.
The Lenovo ThinkVision X1 Wide 27” Wide UHD IPS Monitor (click here for pricing on Amazon) is a desktop based USB Type-C display that supports DisplayPort Alternate Mode and a 4K (3840x2160) resolution.
The Acer H277HU kmipuz 27-Inch IPS WQHD 2560 x 1440 Display (click here for pricing on Amazon) is another desktop based USB Type-C display that supports DisplayPort Alternate Mode but a lower (2560x1440) resolution.
If you want portability, the ASUS MB169B+ 15.6" Full HD 1920x1080 IPS USB Portable Monitor (click here for pricing on Amazon) is a unique mobile display that supports a (1920x1080) resolution and only has a USB Type-C port supporting DisplayPort Alternate Mode for a video interface.
Of course, if you don't have access to any of these displays you can always use the USB-C VGA Multiport Adapter (Click here for pricing on Amazon) or the USB-C Digital AV Multiport Adapter (click here for pricing on Amazon) to connect to any VGA or HDMI monitor.
