Display issues

[Anghellic33]

Hello, I have two problems. Firstly, after the rising tides update when I sign in my display SAYS it's in 1080p but it's zoomed in to only part of the screen until I switch to a different quality then back to 1080 then it's fine again. I've been playing warframe for over a year and never had this problem. Secondly, I can't slide or crouch. Pressing control seems to cut my video feed for a second like my computer is turning off then on. Any help would be much appreciated, I do love this game.
