There's two ways to do this that I know of. In the Mod Organizer program, click on the puzzle pieces at the top of the page. Under SkyrimPrefs.ini go to [Display] and search for 'iSize H' and 'iSize W'. Those are the the height and width. respectively. Change them to what ever you need them to be. Go into where ever you have Mod Organizer installed and go to Mod Organizer>Profiles>(whatever your main profile is [Most likely default])>SkyrimPrefs.ini. Once in SkyrimPrefs.ini seach for iSize H and iSize W. Change them to your needed resolution. Whenever I do that and try to launch SKSE through MO, it says " Failed to initialize renderer. Your display doesn't support the selected resolution. Please set a different resolution in Skyrim's Launcher under 'Display Settings'." Sorry, Ik you posted that a long time ago. Edit: I made a new profile, and it seemed to help with the resolution.
