In almost every case it is ambient light landing on the screen, not the projector: any light in the room adds to the image, and the part it damages most is the black.
Why light hurts black and not white
A projector adds light to a surface. It cannot subtract any. The darkest part of your image is the screen with no light on it — so whatever else is illuminating that screen becomes your black level, and every shade above it is compressed toward white.
The order of things to try, cheapest first
Close the curtains and look again; that establishes whether the room is the problem. Then look at what is reflecting: a white ceiling above the screen, a pale wall opposite, a lamp behind the seating. Then consider the screen itself — a grey or ambient-light-rejecting surface is designed for exactly this situation, and matters more than the projector in a bright room.
What to change in the menu
Switch out of any “dynamic” or “vivid” picture mode. Those modes raise brightness by pushing the whole image up, which is the same thing ambient light is already doing. A cinema or film mode is dimmer and looks better.
When it really is the projector
If the room is dark, the picture mode is neutral, and the image still looks flat, the machine’s native contrast is the limit. That is a specification you can read before buying and cannot change afterwards.
This does not replace the manufacturer's own instructions. Every brightness figure, contrast ratio, power rating and load capacity on this page is reported from the manufacturer's own documentation, with its unit written as published, and named as such — none of it is measured here. A brightness figure that is not expressed in ANSI or ISO lumens is reported as the manufacturer expressed it and is never converted, because no conversion exists.
Questions people actually ask
Will a brighter projector fix it?
Partly, and expensively. Brightness raises the whole image, including the black level, so a brighter machine in the same room gives a brighter washed-out picture. Controlling the light, or changing the screen, addresses the cause instead.
Does a grey screen help?
In a room with ambient light, yes: a grey surface reflects less of everything, which lowers the black level more than it lowers peak white in perceptual terms. In a fully dark room it costs brightness and gains nothing.
