Buy a projector if you can control the light in the room and want an image well over two metres wide; buy a television if the room has daylight, or if the screen has to work at any hour without preparation.
Where the projector wins outright
Image size for the money. Beyond about 165 cm diagonal the cost of a television climbs steeply, while a projector produces a three-metre image at no extra cost beyond a larger screen. It also disappears when it is off, which matters in a room that is not a cinema.
Where the television wins outright
Any room with ambient light, and every situation where switching on has to be instant and casual. A television produces its own light behind a filter that rejects the room’s; a projector adds light to a surface that reflects everything.
The point people underestimate
A projector is a system: the machine, the screen, the mount or stand, the cable run, and usually a soundbar, because the built-in speaker is an afterthought on almost every model. Comparing a projector price to a television price compares one component to a complete product.
The middle answer
An ultra short throw laser projector on an ambient-light-rejecting screen is the configuration built to bridge the gap, and it works. It also costs what a large television costs, which is the honest way to describe it.
Questions people actually ask
Which is cheaper for a very large image?
The projector, by a wide margin, and the gap grows with size. A projected image of two and a half to three metres is ordinary; a television of that width is not a consumer product. Below about 165 cm the comparison reverses, because televisions at that size are mass-market and projectors still need a screen.
What about running costs?
A lamp projector has a genuine consumable, replaced at a few thousand hours; a laser or LED machine largely does not. Televisions have no consumable. Where a lamp is involved, its price and stated life belong in the purchase decision.
