I'm planning on my game being fullscreen, and I'll use the Unity pixel camera to remove sub-pixel movement, but because the resolution 84x48 pixels can't be scaled to 1920x1080, is it a problem if there is a tiny bit of pixel distortion (like for example, 1 in-game pixel is 23 on screen, but another one is 22), or should I just make it be windowed 840x480 or 1680x960?
