Projector vs TV: which is better for your room?
At 100 inches, in the prices we checked, the gap had closed. So the decision is about light, size and the room.
Choose a TV for a bright room, daytime sports, simplicity and the best contrast; in the prices we checked, a 100-inch TV cost about the same as a projector with its screen. Choose a projector if you want more than 100 inches, a picture that can disappear when it’s off (with a roll-up screen), or a dedicated dark room. On October 4, 2026, LG’s 100-inch TV was $3,299.99 and a Hisense ultra-short-throw projector with a 100-inch ALR screen $3,599.99; a conventional Epson 4K projector was $1,799.99 before a screen and mount.
Side by side
| TV | Projector | |
|---|---|---|
| Brightness in daylight | Excellent | Fair to poor; needs light control and an ALR screen |
| Contrast and blacks | Excellent (especially OLED) | Good in a dark room, weak in a bright one |
| Size | Mostly up to 100 inches; very heavy at the top end, and the few larger models cost far more | 80–150 inches is common; a bigger image mostly means a bigger screen |
| Installation | Wall mount into studs or a stand | UST: a low cabinet. Conventional: ceiling or back shelf, cables, beam clearance |
| When it’s off | A large black rectangle | A screen (some roll up) |
| Sound | Built-in speakers, usually weak at this size | Built-in speakers on some USTs; plan a sound system for either |

Prices from the makers’ US websites on the evening of October 4, 2026, before tax and promotions; they change often.
At 100 inches the complete projector setup we priced was $300 more than the TV, not less. The projector’s advantage appears at bigger sizes: the same projector can usually fill a bigger screen, so the extra cost is mostly the screen, while TVs past 100 inches are rare and expensive. These are three products on one evening, though, not a market survey; check current prices for the specific sets you’re weighing.
Which room suits which?
A TV, if:
- the room is bright and you watch in the daytime;
- you want the simplest install and the best contrast;
- 100 inches or less fills enough of your view from your seat (sit within about 13.5 feet).
A projector, if:
- you sit far enough back that you want 110 to 150 inches (about 11 to 20 feet away for the recommended 30–40°);
- you can darken the room for films;
- you’d rather not have a huge black panel on the wall.
Questions people ask
Is a projector cheaper than a big TV?
At 100 inches, not necessarily. On October 4, 2026, an LG 100-inch TV was $3,299.99 and a Hisense UST projector bundled with a 100-inch ALR screen $3,599.99. Past 100 inches the balance tips toward projectors: the same projector can usually fill a bigger screen (the PX3-PRO is rated for 80 to 150 inches), so going bigger mostly means a bigger screen, while TVs larger than 100 inches are rare and carry a steep premium.
Is a projector or TV better for a bright room?
A TV. Even with an ALR screen, daylight lifts a projector’s blacks and washes out color far more than a TV’s.
Do projectors cause eye strain compared with TVs?
We found no good evidence either way. The bigger factors are viewing angle and room lighting: sit at a distance where the picture fills 30–40° of your view, and avoid a very bright screen in a pitch-dark room.
