@TechConnectify a friend used to have one of these old CRT projectors set up in his lounge on a huge scaffold. Given the small size of typical UK houses there wasn't enough throw for more than the picture size of an average TV for the time, and the logistical issues of a lounge full of scaffolding, but he swore by the picture quality. (Also yes, a temperamental beast in need of constant adjustment, so in addition to the scaffolding said lounge needed a stepladder present at all times.)
