I've been learning my way through this the last few years. Started small and cheap, have gotten to "good enough for me" and cheap. Bought about 5 <$200, and a ~$400 low-end epson.

Looking to do outdoor video graffiti and VJing.

You appear to be thinking in terms of resolution, where you'll get better details/sharper focus the higher you go.

For projectors, I've learned to move up in lumens. 6-7k minimum.

Keeping in mind: the higher the luminous flux, the more expensive.
