Can I use a projector in a bright room?

Yes with enough lumens (2,500+) and an ALR or CLR screen, but a TV will always look brighter in daylight.

Do projectors last as long as TVs?

Lamp models need a bulb every 3,000-5,000 hours; laser/LED projectors last 20,000+ hours, closer to a TV panel.

Projector or TV for gaming?

Both work; check input lag. A low-lag projector gives a huge immersive image, a TV gives higher peak brightness and HDR.

Projector vs TV: Which Is Better for You?

Guide

A projector wins on sheer size and cost-per-inch — 100 to 200 inches for the price of a much smaller TV — but needs controlled light or an ALR screen. A TV wins on brightness, convenience and lifespan. For movie nights on a big screen, choose a projector; for all-day bright-room viewing, choose a TV.

The real trade-off is size versus brightness. Projectors make a far bigger image cheaply but their light spreads thin, so they shine in a dark or dimmed room (or with an ALR/CLR screen). TVs are self-lit and stay punchy in any light, but big sizes get very expensive. Many people use both.

Frequently asked questions

Per inch, yes — a 120-inch projector setup often costs less than a 98-inch TV, though you add a screen and a dark-ish room.

How many lumens do I need?

Lumens needed scale with screen area and ambient light. As a rule of thumb, a 100-inch screen needs about 600 lumens in a fully dark room, around 1,300 for a living room with some light, and 2,700+ for a bright room. Bigger screens and more light need proportionally more.

Guides

ALR vs CLR screens

The two are not grades of the same thing, they reject light arriving from different directions, and the right one is decided by where your projector sits. A **CLR** (ceiling-light-rejecting) screen has a horizontal sawtooth structure that only works with light coming from below — that is, from an ultra-short-throw projector on a cabinet. An **ALR** screen rejects light arriving off-axis and suits a short-throw or standard projector further back. Put a UST projector on an ALR screen and you get a washed-out hotspot. Of the 110 projectors we track, 29 are ultra-short-throw (throw ratio below 0.4) and need CLR; the other 81 do not. And the number on the box will not help you tell the materials apart: across our 24 screens, CLR runs 0.5–1.0 gain and ALR runs 0.8–1.65, so 9 of them — 38% — sit in the 0.8–1.0 band where both types exist.

Guides

Projector viewing distance

A common guide is to sit about 1.2 to 2 times the screen WIDTH away. For a 100-inch 16:9 screen (87 inches / 7.3 ft wide) that is roughly 9 to 15 feet. Closer is more immersive (THX); further is more relaxed (SMPTE).
