Last Updated on

Now that you have your projector, how can you get the most out of your purchase in terms of picture quality? Perhaps you are using it for a big outdoor movie marathon or simply a new indoor visual experience with gaming. When dealing with either of these activities and many more, the ability to see all the minute details inherent within the entertainment may be overlooked if not calibrated correctly. 

Needless to say, we all want the best possible quality available from our projectors. The right resolution, appropriate sharpness, and the correct vibrancy of the colors all play a significant role in creating a memorable viewing experience, however perhaps the most important of these to consider when creating aspiring towards that beautiful image is the contrast ratio.

Remember, even the best home theater projector won't be able to meet your needs if it's not set properly.

Contrast Ratio

Contrast ratio is essentially the reflection of light from an all white and black image. To better simplify this concept, all you need to really understand is that the most intense white in contrast to the darkest blacks will give you a much sharper picture; bringing out all faint colors and tiny details found throughout the image.

The ratio for this contrast is given in a numerical value such as 1,000:1 where the 1,000 represents the white of the image while 1 serves as the black. Therefore, if you are presented with a 2,000:1 contrast ratio than it is simply stating that the white of the image is 2,000 times brighter than the black.

So what influences the contrast ratio? Primarily, light affects the contrast ratio the most severely. You could have determined the perfect contrast ratio for you to thoroughly display your power-point presentation within a classroom; however, natural light beaming through a simple open window would without a doubt disrupt the quality of the picture significantly.

Thus, when determining what contrast ratio best suits the environment that you chose to utilize your projector in, you should pay close attention to what light sources may come into play during usage. Some methods to remedy this, chiefly with indoor areas.

Removing All External Light Sources

Beginning with covering all windows and switching off any electrical lights that will be abrasive to not only the image but also to yourself as well.

Choose, if possible, a darker room for the projector. It is recommended to appropriate a space that is painted with a darker tint of color; thus, when all light sources are eliminated the space is then completely filled with darkness.

Finally, instead of using a unspecialized flat surface, such as a wall within the room, invest in a projector screen. All of these methods, though simple, will aid in minimizing any additional sources of disturbance affecting your overall picture quality.

The Best Ratio

Contrast ratios upwards of 10,000:1 are highly recommended when beginning to find that exact ratio that best suits your individual preference; really, the higher the ratio, the better as a rule of thumb.

However, this is not always the case depending on your environment. If you are utilizing a dark enclosed space, you will find that your image quality will not be drastically affected by your modifying of the contrast ratio.

So, in essence, you will spend more time perfecting your surroundings, ridding them of any intrusive light sources, rather than you will adjusting your projector’s contrast ratio.

In the end, the perfect contrast ratio falls upon your individual preferences, and what you personally view as the best picture quality you have produced through experimenting and fine-tuning the ratio.

You may discover that a 9,000:1 contrast ratio creates the ideal visual image for you specifically, however, your audience may find that the image is a bit off in their opinion; leaving them with a far less enjoyable experience.

The best solution for this issue is to find a happy medium where both you and your audience are satisfied. If you alone are the only one that will be using the projector you will have no problem here and should be able to find that perfect contrast ratio without ever having to make alterations to it in the future.

However, learning what best ratios fit for every situation will be the best course of action; for you will always be prepared to produce the ideal visual for a variety of conditions quickly and with great results.
