It always blows my mind what ideas people have what "rich people" have or want.

I know a few 'filthy rich' people and some of them don't even own any TV or projector, because they're totally content with a laptop screen and don't want their kids to be exposed to TVs. You will not see their wealth unless you know where to look.

Once people have money, most of them begin to think about what actually serves them and what doesn't; if you can afford anything you want, you usually become more humble and selective. There's simply no point in owning things for the sake of owning them any more. Displaying your wealth usually has far more downsides than upsides. What we see is the outliers.

Truly rich people do not have TVs.

Or if they do own a ultra high end TV like a C Seed N1 they hide them away inconspicuously.

It is like eating cheap and nasty junk. If you are rich you avoid it or eat it discreetly...Or your acquaintances laugh at you.

Multi use rooms require TVs.

Projectors cannot handle ambient light without being a fire hazard.
