One thing I’ll mention is I know it’s so tempting when that projector arrives to open the box and fire it up.One more observation, the extreme bright corners have dissipated further for me and a 100% black screen is smoother now; Im guessing there was some moisture/residue inside there that is slowly dissipating away that is causing internal reflections.
This may be fine if you live in the warmer climes but if you’re like me in the northeast or even worse in the midwest, with this frigid weather we are experiencing, that is not a good idea.
Your projector is likely close to the same temperature as the outside temperature as most delivery trucks are not heated in the cargo area.
You would not believe how quickly that warm moist air in your house can condense on those cold parts of your projector.
This can cause all sorts of problems from moisture droplets inside your lens to causing shorts in circuits and motors.
Let your projector stay in it’s box a few hours, even a day is preferable to allow it to slowly equalize with the room temperature. You will be happy you did in the end.
