Windows 10: Windows 10 4k Output Option Disapeared

I am working on a 1st gen Microsoft Surface Laptop. I recently purchased a Samsung 4k monitor, and connected to my Surface Laptop using a DisplayPort to HDMI cable. The very first time I plugged it in, within Windows display settings, the option for 3840x2160 appeared in the resolution list, and the image on my monitor was in 4k.

Windows 10 Tweaks

Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

4K Monitor Loses 4K Option

Last night (11 Dec 2015) there was a Windows 10 update (I am running Windows 10 Pro). This morning my 4k monitor (ASUS PB287Q) was showing up as 1080p, and Settings does not recognize that this is a 4K monitor. The 4K resolution simply does not show up as
an option. Nor does the graphics card (NVIDIA GeForece GT 370) recognize that it is 4K.

Why would Microsoft mess with any of that? I find this really troubling. Do I reinstall a driver for the monitor? They don't have a driver specifically for Windows 10, just Windows 8.
