All of this sounds good on paper. But surely, the manufacturers have done their research? You can get decent projectors for £500 or less, far cheaper than the large TVs. The biggest issue with the projector is the need for a dark room. The vast majority don't have a dedicated cinema room, and a lot of living rooms where the TV resides, are very bright. All my friends are impressed with my projector, but only 1 of them is going for one. Others don't think their room is suitable for one. Money isn't an issue.
No manufacturer holds the patent for 4K chips as far as I'm aware, unless you can provide any news proving otherwise.
What you say may be true for the average 3 bed semi in Surbiton (or wherever) but the World doesn't end at Dover, and over here an awful lot of homes built in recent years have either dedicated movie rooms or basements that can be, or indeed have been, turned into movie rooms. We also have these things called "night time" and "curtains". I am sure they're not confined to the Americas. The potential American market alone must be huge, yet prices remain stubbornly high. I'm not going to waste my time doing a patent review for Sony and 4K projectors. Just typing in "Sony" and "projector" came up with 184 international patents filed by Sony in the last ten years. You are free to do so yourself. There must be a reason why their competitors, rivals even, haven't entered the 4K PJ market, however. I very much doubt it's got anything to do with demand. Think about it. Just about every niche product has a competitor, whether it's the iPod, iPad, iPhone, iToiletSeat, i-you-name-it. Likewise, although Honda has sold gazillions of Honda Cubs (C-50, C-90 step-throughs) across the globe, it still makes 1000cc sports bikes sold in the UK in the hundreds or perhaps a thousand or two each year, and the small market doesn't stop them. Rivals like Suzuki, Yamaha, Kawasaki, Ducati even, also produce competing 1000 cc motorcycles for that small, niche, super high performance market. Likewise, some brands build super-super-prestige 85 inch 4K HDR OLED TVs (costing $10,000 or more over here) as much as to be walking / rolling / sitting advertisements for their mainstream, mundane products (like 40 inch 1080p or even 32 inch 720p sets) as anything else. Anyway, for whatever reason, Sony seems to have a monopoly
right now, and until that monopoly ends, prices will remain high. Why would they cut their prices anyway, if "money isn't an issue" to your friends?
