Complex setup, but easy PLP once done & game looks perfect.
(PLP screenshot with bezel effect)
1. In-game fullscreen, play to safe place, change the resolution (adds file entry), save, quit.
2. Edit %USERPROFILE%\Documents\BioWare\Mass Effect 3\ BIOGame\Config\GamerSettings.ini. ResX & ResY= your base PLP resolution.
3. SoftTH (DX9 x86).
4. Flawless Widescreen (FWS):
A. Load game plugin, checkmark all (enable, FOV, Renderer, HUD), leave FOV slider 0.0, then quit.
B. Find (path-to-FWS)\PluginCache\FWS_Plugins\ Modules\MassEffect3\ Dependencies\Scripts\MassEffect3.lua.
C. Replace (Notepad) the following strings (no quotes), then save:
i. "DisplayInfo:GetWidth()" becomes #### (base PLP width).
ii. "DisplayInfo:GetHeight()" becomes #### (base PLP height).
iii. "DisplayInfo:GetiOffsetX(0)" becomes #### (side screen's width).
iv. "DisplayInfo:GetiOffsetWidth(0)" becomes #### (center screen's width).
v. "DisplayInfo:GetiOffsetHeight(0)" becomes #### (center screen's height).
5. Start FWS, start game. It spreads full at player view.

NOTES:
1. Hor+ & FOV looks proper. All these are rendered perfectly on only center screen: HUD, menus, Galaxy Map, FMV & rendered cutscenes.
2. Optional FOV (not needed): FWS slider. Slider at 0.0 looks proper (screenshot), but may feel a hint too close for 3P in multi-monitor.
3. FWS must be restarted to recognise edits. Should backup lua file. If game reverts in future, paste file back in.
