Hi there, We have an Epson powerlite 2165 that we need to move a few times during a production. We use a/v mute and have it spiked so it rolls on and off stage to the same location each time we bring it back on again. I'd like to turn off the auto keystone or whatever feature is making it try to adjust when we reset the projector. Is this a possibility? If not, any other tricks? Thanks!
