Wondering how to watch projector in daylight? It seems ridiculous, but it's totally necessary if you want your screens visible. Check out the following steps on how to properly set up a projector for outdoor use.-Use a 3200K bulb with at least 90 lumens brightness to lower the temperature of emitted light. These are designed for integration into outdoor building surfaces or off-site applications that are exposed continuously to sunlight.-Install an anti-glare filter on your projection lens, which can reduce image reflections by as much as 90%. Such filters are available for purchase or can be made with DIY materials like window tinting film cut into strips and applied over the lens using silicone sealant adhesive.-Use a long throw projector to maximize the range of view outdoors. Long throw projectors cover large areas with minimal distortion, which is important for outdoor use.-Use a 3:1 zoom ratio, or higher screen size with a smaller projection distance, which reduces the need for image scaling and greatly improves image quality. A maximum screen width of about 4"x4" is recommended for both indoor and outdoor use. However, using a smaller screen size on an outdoor environment when illuminated by the sun will result in higher glare from the sun and lower contrast ratio from uneven illumination sources.

-Projector images should always be viewed under ambient daylight conditions to ensure that viewers can see the content clearly. Indoor viewing under artificial light is not recommended for viewing best-quality images.-Projector colors, regardless of model, should be calibrated to accurately reproduce colors under actual outdoor illumination conditions. Check that your projector meets the projector color temperature specifications specified by the manufacturer. If you're familiar with color temperature from photography, you may want to choose a model that has a color temperature lower than 5000K and higher than 5500K if you plan to view content outdoors and close to midday. This will reduce unnecessary glare from the sun and provide for better image contrast ratio at an equal brightness level.-Choose a projector with a lens shift function. This feature allows you to use the projector outside with minimal distortion and glare, which is preferred for viewing large screen content at a distance.-Ensure that the greenhouse covers and fans are installed properly to prevent unwanted light reflections. Ensure that both screens are shielded from direct sunlight during operating conditions. It is recommended to keep these screens in operation for at least an hour after sunset or before dawn so that the screens may be cleaned and washed.
