Already there and available via functions that can be called from the XB1 graphics layer. Which is why 99.99% of the games that are cross-platform between XB1 and Windows 10 display correctly on the XB1. Sega just doesn't bother to use the code libraries.
@zaffy2005 Any recent LCD monitor designed for desktop computers will likely work fine. I run PSO2 with my XB1X connected via HDMI to a 23" LCD I bought 2 years ago for $130 and the game displays correctly with no clipping at edges. When displayed on my 8 year old Sony Bravia HDTV though, there's clipping and no easy way to resolve it.
