There are a few things you can do, like positioning the screen in the right way, using covering and so on, that will make it “work” but the movie you are seeing will not be as clear as it will if you were watching it during an evening. To be fair, very few projectors will actually claim that they are a video projector for daytime use. Some may say that they are “suitable” but in my years of experience, I have yet to see a screen or a projector (that is not thousands and thousands of dollars) claim to be a screen for outdoor use.

Why do we need window treatments?
The primary reason why we opt for window coverings is to safeguard privacy inside the home and light control. Your home is your sacred sanctuary where you can feel safe and comfortable. Window shades help to seal off your interiors from the eyes of intruders or even harmless curious neighbors. Light control is another major consideration. Unfiltered natural light contains harmful UV rays and too much glare that can cause irritation to the eyes. UV rays can cause health hazards and also damage your furnishings. Diffusing natural light will help you to enjoy the benefits of sunlight sans the harmful effects. There is also another consideration that most of us will agree to and that is the need for an outside view. Once you are inside your house you are cut off from the outside world and the windows are the only means of connecting with your surroundings. If you have a beautiful view to behold, or you have a pretty manicured lawn or porch, or your house gets treated to an amazing sunset or sunrise, you would want to preserve that view. While privacy is extremely valuable you would not want to cut yourself off from all the prettiness around you. And finding that balance between privacy and view is what makes choosing a window treatment a challenging and rather daunting task.
