I've recently purchased a 4805 and want to mount it on the ceiling to get it out of the way. The problem I have is that my house is a timber frame construction and is linked with our neighbours. Everytime they close a near outside door there is a loud bang which also will transmit a reasonable shock through the ceiling (its within 10 feet). I would like to purchase a ceiling mount that can dampen any shock received so that this shock doesn't pass to the projector (and bulb). Are there any ceiling mounts available that have this facility. Again with people walking around an upstairs room will transmit shock through the mount. I really want to ceiling mount the projector but am concerned about this so much that I have not done this yet. Before anyone asks, it is not practical to leave the projector where it is on a table as I have to keep moving it. I've looked around but found nothing yet. help.
