PC Graphics

So, I came back to my pc this morning to this stupid, over-the-top overscan.  My monitor has no overscan settings and windows is adamant it's displaying at full resolution (2560x1080).Also, my second monitor is not detected at all.

I have tried:

• removing + reconnecting cables
• swapping cables
• restarting
• updating radeon software + drivers

My system:

CPU: Intel i7 6850K

GPU: AMD Radeon RX Vega 64

Motherboard: Asus X99 Deluxe ii

Monitors: LG 25UM58 25 inch Ultrawide (2560x1080)

Display cables: Rankie DP -> HDMI cables

Any ideas as to what has gone wrong?  Cause this was working fine last night.

Just randomly decided to try running a fullscreen program, decided on the Hitman 2 benchmark, and it runs fine (no overscan).  When it finishes, however, windows still displays with crazy overscan.  And the secondary monitor was still off through all this.
