Yes, everything aligns properly. The only issue is with the screenshots.

I'm having issues with the resolution of screenshots. My computers resolution is 1920x1080 and I play on a 28" monitor. Before I played on a 21" monitor and never had an issue with this. I've went into the screenshot settings and the highest it lets my resolution go up to is 1280x720. The best I can get the picture to look is if I choose "original" and even then it comes out like the image below. Does anyone know a fix for this?
