I've never had a problem with scattered light curing any surrounding resin at normal layer times. I have left the projector shining on the vat for long periods just to see the outcome and it did cure most of the bottom of the vat. My favorite resin is MakerJuice, and it is not very sensitive to room light or scattered light from the projector. The ideal brightness is 3000 lumens, but I would think a threshold depends on the brand of resin.
I use a Acer H6510BD projector because there are no mods required to use it. Some people install a shutter like the one in the link below from Muve3D to stop scattered light, but I have never had a need for it.

And those would be good ideas to try!

To further improve the projector performance you can do what I did to mine. I removed the color wheel and replaced the hot mirror on the halogen lamp with a UV pass filter. I cut my cure times in half and don't get any background curing. I am currently using Autodesk Magenta resin.
