Melissa Forrester If you are learning about the projection plane, you must have heard the term “screen gain” no less than once. In fact, “screen achievement” is more important than you think. This parameter plays a vital role in the screen’s performance, affecting how this device reflects light.
So, what is projector screen gain? What is the best parameter above? This article will answer your questions through the information below.

What Is Projector Screen Gain?
Projector screens work on the principle of light reflection. It also means that the more reflective this device is, the brighter the image quality will be.
The main gain is a technical parameter to measure the reflectivity of the projection plane.
Experts will determine the brightness to gain by calculating the ratio between the light reflected from the projection plane and light reflected from a standard reference table.
For example, a device with a gain of 1.0 means this projection plane has a reflectivity equivalent to a standard reference panel.
Meanwhile, a 1.5-gain screen will reflect up to 50% more light. The device with 0.8 achievements only has 80% reflectance of the standard reference panel.
Therefore, the higher the above parameter, the greater the achievement, and it is not difficult to understand that thanks to that, the brighter the FHD image.

Higher Or Lower Screen Gain, What Is Better?
In terms of gain, there are two main types of monitors: one with high achievement and another with a low one.
The question here is, which is the ideal choice? Why should users be hesitating between two different models when 1.0 screens are the norm?
Each option has its pros and cons, and even a 1.0 monitor isn’t always the ideal choice for your needs. Specifically, with a high-gain device, it will impress with its excellent reflection ability.
Focusing light on a narrow reflection angle is both an advantage and a disadvantage. Because the viewer may only pay attention to the central area of the image, it isn’t easy to have an experience that covers the entire screen.
The product has a lower reflective ability, which will naturally reduce the image’s brightness significantly. However, the viewing angle of these devices is wider.
Combined with that, these devices can also increase the projector’s contrast ratio, delivering commendable vivid images.
That is also why devices with not-so-excellent light reflections are often one of the most optimal choices in home cinemas.
High Gain Pros & Cons
There are many reasons to favor a high-gain projection surface. However, this type of product is not in all cases able to provide the most impressive experiences. Before making a choice, consider some pros and cons:
Pros:
- Deliver bright and vivid images
- Come with a special coating that eliminates light.
- Very suitable to appear on mobile devices.
- A project without worrying about ambient light.
- Ideal for outdoor displays.
Cons
- There is no wide viewing angle.
- Color reflectivity is not perfect.
Low Gain Pros & Cons
When choosing any device, most buyers choose products with the best parameters. Yet, low parameters can bring better experience in some cases.
To better understand the benefits you can get with low-gain devices, as well as the problems you might face, here are some pros and cons you can consider: :
Pros:
- The viewing angle is more comprehensive.
- Reproduction of colors such as red and green is quite good.
- Enhance the contrast ratio, especially the dark colors.
- Ideal for movie nights.
- Low dynamic range.
Cons:
- Not suitable for projector models with low brightness.
FAQs
Like every other parameter of the projection screen, there are quite a few exciting things that you may not know. If you are interested, don’t miss the answers to frequently asked questions that will appear shortly:
1. Is a higher growth projector screen better?
As mentioned, each option has its pros and cons. The most significant advantage of the high-growth projection screen is the brightness, but in terms of viewing angle, this option does not prevail.
Therefore, devices with good light reflection are only great if you are facing the center of the screen or not sitting too far from the center.
2. How do I check my screen gain?
You don’t need too much-complicated equipment to conduct the test. Your task is to perform a series of simple actions below:
- First, paste a small piece of the standard reference sheet on the screen.
- Then use the PJ to illuminate the reference piece. Don’t forget to measure the reflected light of the projection plane and the reference panel with a dedicated test lamp.
- Once you have two critical parameters in hand, you can calculate the growth of the device.
3. Do I need a particular projector for rear projection?
The answer is no. Nearly all options available on the market today can flip the image, meeting users’ needs on the rear projection surface.
If you are not confident about the display quality, you may need a projector model with a short-throw ratio.
Is the rear projection brighter than the front projection?
The front screen will give a better projection effect in a dark room. The reason is the contrast; saturation in this aspect is quite suitable for the use environment.
