Is a projector screen necessary?
Many new comers to projectors may wonder, can I use a projector without a screen? Can I directly project the images to the wall? Is a projector screen necessary? Does a screen make a great difference? The answers are out below.
Before everything, can you use a projector without screen? The answer is yes! A projector is merely shining a light on a surface, and if that surface is clean and reflective enough, then you'll be able to see a picture on it. A white wall, white sheet, or another light-colored semi-reflective surface will do just fine in a pinch. Now that, what is the value of a projector screen? The simply answer is a projector can help to make the great use of a projector.
A projector screen will cater to the pursuit of picture quality perfectionism.
Projector screens are specifically developed to cope with the images emitted from the projector. If the walls or sheets with mismatched colors or the surface texture degrades the quality of the reflections, you will experience less than ideal image quality. The biggest advantage of buying a projector screen is that it gives you more control than you’d get with a bare wall. A perfectly smooth wall is great, but any minor imperfections could harm your projected image.
The projector screen is flat and has a special coating designed to improve its reflective quality. This ensures a brighter, more detailed image than what you would get with a wall or sheet. Since the projector screen has a clear border, this can help frame TV shows or movies in the center of your home theater or living room.
There are also some inconveniences of owning a projector screen. A screen is at least somewhat permanent. If there is some stuff around the wall, you need to move them away to take place for the setup of the screen. And it is not that easy to move or realign.
What is it like to directly project the images onto a bare wall?
The main appeal is that you don’t have to shell out any money for a screen. At the same time, the bare wall is able to support a decent image quality with a normal projector.
Second, projecting against the wall also makes moving the projector super easy: place it where you want it, make minor adjustments as needed, and enjoy the giant image.
A bare wall will compromise the projection effect, especially color contrast and picture details. Then, it can be easily influenced by ambient light and space conditions.
Do you need a projector screen?
If your projector is a pretty expansive one and you plan to replace a TV with it or build a home theater, then it would be a must-one. If you have higher requirements for picture quality and color, a screen will be more than enough to fulfill you. A projector screen will greatly improve your experience and entertainment.
If you have a low-resolution projector, are just setting up a quick movie for the kids in the garden, or don't plan to use your projector in that particular room again, then a sheet is acceptable for the odd movie night.
