Unlike a TV set, a projector is vulnerable to light. Therefore, you need to pay more attention to the brightness when you pick a projector. Many projector beginners wonder how to make the projector brighter.

In this guide, we will conclude the top 10 effective methods to make the image brighter and answer related FAQs.

How to Make Projector Brighter?

Here are the top 10 methods to improve the brightness of your projector.

Clean the Lens

If the lens module is covered by dust, the light output will be affected. Therefore, the lens should be cleaned regularly to ensure normal light output. You can use a vacuum cleaner to clean the dust on the lens and do not use any other erosive reagent.

Increase the Brightness

Some projectors’ brightness can be adjusted in the image Setting. You can find the brightness in the setting and adjust the image to a higher level. Let’s take the Epson projector as an example, enter Settings, then choose Brightness level, you can adjust the brightness level to a higher level from 0 to 100%.

Adjust the Color Mode

Some projectors don’t support brightness adjustment and you can switch the color mode or image mode instead. For instance, the Epson LS500 projector has four color modes, including Dynamic, Bright Cinema, Cinema, and Game. Dynamic is the best for videos or games in a bright room.

Quit The Eco Mode

The Eco Mode is suitable for saving power consumption and prolonging the lamp’s life span. But if you switch to the Eco Mode, the light output will be reduced greatly. Then, the image brightness will also be lowered. If you want a brighter image, then you need to quit the Eco mode.

Clean The Vent

You need to clean the vent regularly to avoid overheating. If the projector is overheated, the overall performance and brightness will be affected.

Replace the Lamp

Some projector adopts lamp as the light source, which has a relatively short lamp life. After long-term use, the projector’s brightness will be lower and lower. You can replace a new lamp for the projector and improve the brightness. Generally, a lamp-based projector has a lamp life of 5,000 hours while a laser projector has a long lamp life of 20,000 to 3,000 hours.

Use an ALR Screen

An ALR screen refers to an Ambient Light Rejecting screen, which can bounce a large amount of overhead lightning back and provide a brighter image for the viewer.

Lower Ambient Light

To improve the image brightness, you can try to lower the ambient light. For example, you can turn off the light in your room or close the curtain to make the room dark. This is especially important for some projectors with low brightness.

Reduce the Image Size

Generally, a projector will label the max image size on the projector specification box. To ensure the best image quality, the image size can be slightly smaller than the max image size. For example, a projector has a max image size of 120 inches, but a 100-inch screen delivers the best image quality. If the image is too big, the image may become blurry. Therefore, you need to check the recommended image size of the projector when picking a projector.

Shorten the Cables

If the connection cable of the projector is too long, the signal and the brightness of the projector will suffer severe attenuation. Therefore, please do not use a long cable to connect the projector.
