Hi! I'm attempting to increase the screen resolution in my game mid-development, but am a bit confused about the pixel scaling. I have set the screen size to 1104x624. This looks fine in windowed mode, but the graphics turn disastrous when I go into full screen. Here it is windowed:



And here it is full screen:


(It doesn't look as bad in the screenshot, but is very noticeable when playing.)

I know it's normal for this to happen because of pixel scaling, but how can I reduce the jaggedness/make it look smoother? I have tried plugins like Galenmereth's pixel perfect, but it doesn't work for me (I assume because of the style of my graphics). I don't know if this is possible, but is there a way to get RPG Maker MV to recognize the player's monitor's resolution and automatically adjust to the best resolution for that? (Possibly a silly question.)

I see fullscreen work just fine for many other RPG Maker games (Ib, Lily's Well, Mad Father, etc) that start out in windowed mode. How can I get fullscreen to work smoothly like that? Do I have to redo the graphics/scale them to match a new resolution? I'm not necessarily looking for a plugin here, but appreciate any answers. Sorry if these questions are too obvious.
