Try re-setting the camera options and things like field of view back to their original settings in the game and then adjust them to your liking after that. I still had mine set for playing with my old monitor before I switched. That helped a little too. Unfortunately for movies and other internet video, unless it is filmed in ultra wide you will always have some black bars on the sides even for 4k and 1080p. on the other hand though, things that are filmed in ultra wide look amazing.
