When it comes to projectors, brightness isn't just about the amount of light a device can project onto a screen. It's about how that light translates into image quality in different environments. How the human eye perceives brightness is influenced by several factors: the projector's lumens, the size of the projected image, the projection surface, ambient light, and the content's brightness. Let's break these down:

1. Projector Brightness: Measured in lumens, this indicates how much light your projector can emit. Higher lumens mean a brighter image.

2. Projection Size: Bigger isn't always better. As the image size increases, the same amount of light is spread over a larger area, reducing perceived brightness.

3. Ambient Light: The natural enemy of projectors, ambient light can wash out your image. More ambient light requires higher lumens for a clear image.

4. Projection Surface: The color and material of your projection surface can enhance or detract from image brightness. A white wall reflects light better than a dark one.

5. Content Brightness: The actual content you're viewing also plays a role. A scene set in bright daylight will appear differently from a dimly lit interior shot.
 

For the Capsule 3 Laser projector, controlling the projection size and ambient light is crucial for the best viewing experience. Although the Capsule 3 Laser supports a screen size of 30-120 inches, maintaining optimal brightness at each size requires strict control of ambient light. The projector has recommended screen sizes for different ambient light conditions, as shown in the following table:

Q1: How can I improve the viewing experience if my projector is used in a bright environment?

A1: If your projector is used in an environment with brightness exceeding the recommended levels, we suggest turning off the lights or adding curtains to adjust the ambient light brightness. This will help ensure a good viewing experience.

Q2: What should I do if I can't adjust the ambient light brightness?

A2: If you are unable to adjust the ambient light brightness, consider moving the projector closer to reduce the screen size. This will increase the viewing brightness. Note that reducing the screen size through keystone correction will not enhance the viewing brightness, as it crops the output brightness at the edges and does not increase the brightness per unit area in the display region.

Q3: How can adjusting the battery mode affect the brightness of my projector?

A3: Ensure you check the current battery mode of your projector. When plugged in, it is recommended to use Standard Mode. Using Low Power Mode or Eco Mode while on battery power will reduce the light output, preventing the projector from reaching its maximum brightness. To restore brightness, select Standard Mode in the battery settings.

Q4: What picture modes can I use to enhance brightness?

A4: Standard Mode provides a balanced setting for color accuracy, color gamut, brightness, contrast, and battery life. For more vibrant colors, select Vivid Mode. If you are presenting documents and do not require high color accuracy, choose Conference Mode for maximum brightness. Generally, we recommend using Standard Mode.
