Both solutions require running game from AvP.exe (enforces DX9). Fullscreen: SoftTH (DX9 x86). In-game select massive resolution. OR Borderless: Shortcut/launcher argument -subwindow. ShiftWindow (+ border = borderless). Optional FOV (not needed, recommended): Use FOV Changer *, run it from any folder. Enter preferred FOV, click Set & Enable & DX9. Bind to e.g. F12, trigger in-game. When FOV reverts, repeat (rarely).

* Predator's FOV is bit weak, ~75 is better (stock ~69). Alien's FOV bit strong, ~82 better (stock ~88). Marine's stock FOV great as-is.
