You could use the crt-geom shader from BGFX, as it has a tilt-prameter, that you can adjust on the fly. Also its easier to "correct" the screen, by doing it with the artwork itself, i.e. creating proper orthagonal views with Photohop or similar, rather than changing shaders. If you are satisfied with the tilt settings, you can duplicate the shader and change the tilt settings accordingly inside them. Afterwards you can change the game .ini setting to load your copy of the shader file. This way you dont need to change it everytime the game is loaded. This is a provisionally solution, until we have BGFX shader settings, that are saved automatically.

"fisheye" settings (and to some degree manipulations to fit the screen), can be done with HLSL with these parameters:

distortion 0.0
cubic_distortion 0.0
distort_corner 0.0
round_corner 0.0
smooth_border 0.0

you need to play with them, to find your settings.
