W8.1 Update 1 screwed up my display

As you can see from this, after updating to Update 1 on my desktop, my display settings are all fucked up. (this is how it looks on my monitor) It's displaying it at native resolution but I'm getting this weird black box like it isn't scaled properly. I keep trying to install the Nvidia beta drivers to see if that's the problem but it refuses to work.

Is anyone else having this issue?
