The first and foremost important thing that matters in a projector’s image quality is its “Contrast Ratio”. Since now you are having a projector, it’s important to know how you can get most of the purchase yield in expressions of image quality.
Every of single detail matters in image quality. How and what is a good contrast ratio for a projector is a question that disturbs many projector users. From perfect resolution to correct vibrancy and sharpness, everything has its importance in its shoes. All these balanced things together, give us the desired image quality. However, the game-changer card in the game is the Contrast Ratio.
What is Contrast Ratio
Before we tell you the best contrast ratio for your projector, first let us see what contrast ratio is. There is no such hard and cold definition of contrast ratio: don’t panic.
The contrast ratio is the difference between the white and black light of the image expressed by numbers. To better understand this, you need to understand that the sharpness of an image is at its high peak when comparing the whitest and the darkest light of the light.
The come out contrast ratio of this is will be 1000:1. Where represent the white side of the picture and 1 as the dark side. Similarly, if you have 3000:1 then, 3000 is the white contrast and 1 is the dark one.
So, What Is a Good Contrast Ratio For a Projector?
Well, according to the good rule of thumb, the best and the most recommended contrast ratio is 10,000:1. This contrast ratio is best to avoid every wear and tear.
“The higher the contrast ratio, the better will be the image quality.”
However, this contrast ratio will also be affected by the surrounding. If you use this ratio in a dark environment, then you will notice that the image quality is extremely impressive as you may think of it. For better experience and results, spend some time in your environment to figure out the desired contrast ratio.
Note that, every person has its likes and dislikes. This recommended will prove to be best for some people, while for others it may be just so so.
9000:1 contrast ratio is also a good one. But as mentioned above, some may find it okay, while others take it as a bit off. Personal experience and preference will win in the end.
Why Is Contrast Ratio So Important?
Many people ask that why do I even care about contrast ratio, mean is it that important? To all the people out there who have the same question (even if you), the simplest and the honest answer is, Yes, its Hella important to maintain the contrast ratio of the image.
Think honestly what is the use of having an image quality that doesn’t even show the image properly? According to the good rule of thumb once you spend your money on any product, and then it is your right to get the best outcome from it.
What Affects the Contrast Ratio?
The biggest enemy of contrast ratio is none other than “Light.” A little amount of room light or any other outdoor light is enough to destroy the settled contrast ratio. Either you have a 1000:1 or 10,000:1 ratio, just turn on the light, and then try to distinguish between them.
Try the following method to keep the contrast ratio maintained.
- Cover the windows: Try your best to eliminate all the outdoor light coming from the windows
- Turn the light off: Keep the dark as possible
- Dark walls or ceiling: As mentioned above, the darker the room, okay will be the contrast ratio
Lastly, even after trying all these mentioned ways, the contrast ratios remained disturbed, and then try some electronic techniques to increase the contrast ratio. Or you can go with the second option of having a bright projector.
A bright projector can reduce the effect of explosive light but cannot eliminate it.
How to Measure the Contrast Ratio?
There are two common ways to measure the contrast ratio. The first is ANSI contrast and the second is On/Off contrast. The first method “ANSI Contrast” is the valid method to measure contrast ratio. This method is hard to handle only used by some manufacturers. While on the other hand, the On/Off method is the easiest one, but it gives false readings. Let us see the difference between them.
1. On/OFF Contrast
The On/Off contrast measure reading by measuring the brightness of the white block of the IRE trial design (on) and the brightness of the black block of the IRE trial design (off). The outcome 10,000:1 contrast ratio will indicate the ratio of white is 10,000 xs brighter than black.
2. ANSI Contrast
This method is a more advanced and accurate one. ANSI contrast doesn’t use the IRE test pattern method; instead, it uses a checker rectangular board. The rectangular board is consisting of 8 black blocks and 8 white blocks. The brightness of the white & blocks are measured than an average is calculated. After taking the average values, the ratio is calculated.
The calculated ratio is known as the ANSI Contrast.
We do hope that after reading this article your all queries must all solved. In this article, we give you detailed information about what is a good contrast ratio for a projector and how to calculate it.
Figuring out the best contrast ratio for a projector is not such a difficult task. We have mentioned the methods to calculate it.
To enjoy a good image quality, do maintain the contrast ratio. The contrast ratio is the actual game changer of image quality.
Lastly, every person will prefer a different contrast ratio per its taste and priorities. Do figure out your preferred contrast ratio or try our recommendation.
