I’ve seen the Eidophor projectors in use around 1980. They were very large and gave brilliant pictures fed from 2” video tape. The screen used was a cinema type about 30 feet across.
I worked for a dealer that sold the Sony projectors at that time and they cost about £7000. The Eidorphor was about £200,000. So not going to be a domestic product, plus you would need a spare room to house the projector and it’s associated equipment.
