It's a JVC RS10, wondering if flipping it after 150 hours table mounted right side up and then flipping it over and ceiling mounting it will cause any issues? I had heard the lamp 'burns in' and then can flicker if you flip a projector.
I have an HD2K Optimized by William Phelps in 2007. I had it on for like ten minutes on a table, and he could tell when he had it ceiling-mounted during his optimization process. However, you have to consider the source.
