Most of us wait thirty minutes before setting zoom and focus adjustments for storing in the memory positions. However, in my own case, I have found that a warm up period of a couple of minutes is adequate for actual viewing. (Most of that is to allow the lamp to reach its full light output.) As you observed, the small changes that occur in focus as the projector warms up are virtually impossible to see at normal viewing distances IF the projector has been properly focused when it is warm.











I am now happy. I will have to figure out the dimensions and tape off my area, then save projector zoom settings. Then paint.
