There are many different things to think about when you’re setting up your own film area. Whilst finding the best projector screen is definitely of importance, you need to consider what type of screen you actually need.
You’ve probably seen “screen gain” used online, and most people aren’t exactly sure what it means. Although it might appear to be confusing, it’s actually pretty easy to understand. And knowing what screen gain means will help you to choose the right screen that’s compatible with your projector.
So, let’s look to learn a little more about screen gain.
What is Projector Screen Gain
Screen gain is quite simply the brightness of the image that you’re projecting, which is determined by the screens surface. It is a measurement of the reflectivity of the screen at a zero degree viewing angle, which is directly in front of the screen itself.
If you have a screen gain of 1.0, and a projector has 3000 lumens of brightness, then the image that you’re going to see is 3000 lumens in brightness.
However, if you’re using a screen with a lower gain, then the brightness that you see will be less. So, that same 3000 lumen projector on a 0.8 gain screen will only be seen as 2400 lumens.
And similarly, if you’re using a screen with a higher gain, then you’re going to end up with a brighter image. A 3000 lumen projector used with a screen with a gain of 1.1 is going to result in a 3300 lumen image being display.
Simple, right? Well, this is the basic answer to the question, but there is a little more to it than that. If you’re not sure whether you should opt for a high gain or a low gain screen, then let’s look at some of the benefits and drawbacks of using a high or low gain screen.
Pros and Cons of a High Gain Screen
There are some benefits to using a high gain screen, especially with a less powerful projector. Let’s take a look at a few of them, as well as the drawbacks too.
Pros and Cons of a Low Gain Screen
In some scenarios, a low gain screen might actually prove to be the better choice. Here are some pros and cons to using a low gain screen.
In conclusion, it’s actually pretty easy to understand what screen gain is. If you’re looking to project outside or in daylight, then a high screen gain might be the best way for you to project enough light to be displayed clearly.
However, if you’re always watching films in a darker condition, then a neutral or even negative gain could prove to be the better choice. it all depends on the environment you’re going to be using your projector screen.
