When choosing a home entertainment projector, brightness (also known as lumen) is one of the most important considerations. It is also worth noting that, depending on the placement and location of your home projector, you can double or reduce the brightness by half!
Different lumen range recommendations
The brightness unit of the projector is lumens. The human eye perceives the brightness of the screen based on two things-the amount of light output by the projector and the reflectivity of the screen. However, higher light output does not mean that the viewing experience will be better. When using the projector, the screen should be bright enough to make the projection clear and delicate, but not too bright, otherwise it will cause eye fatigue.
The choice of lumens depends on the lighting conditions of the room where the projector is placed. For example, if you plan to use the projector in a bright room, or use the projector in a room where the lights cannot be dimmed, only a high-brightness projector can project a bright screen image.
| Lumen range | Suggested location |
|---|---|
| Less than 1000 lumens | Low-brightness projectors are only suitable for use in dark environments. |
| 2,000 to 3,000 lumens | This is the common lumen range of projectors. This type of projector is suitable for dark or dimly lit rooms. |
| 3000 lumens or more | This type of projector is very bright, suitable for dark rooms and brighter rooms. |
Where do you use a high lumen projector?
The main advantage of high-lumen projectors is that they are suitable for most environments, because high lumens can provide a sharper screen image in a larger space and a bright surrounding environment.
- Brightly lit environment
- In an environment with a large screen, low-lumen projectors cannot provide enough brightness
- Need to specify the screen brightness level of the environment.
Note: The screen brightness depends on the image size, the gain of the screen surface and the light output of the projector; the projection distance and the projection ratio of the lens have no effect on the brightness. - Meeting rooms and living rooms-most of these venues contain some level of lighting
The advantages of adding a high-brightness projector at home
Some people may worry that if they want to buy a projector for their home, they may need a special room with very low lighting or a home theater with well-controlled lighting. But in fact, a projector with a brightness of 3,500 lumens has enough versatility to project bright images in most environments. Some 3500 lumens projectors, such as the ViewSonic PX747-4K, use 4K UHD resolution, which is currently the perfect resolution because 4K content can give full play to the clarity and finesse of 4K.
