Every year consumers spend money to buy a TV that will give them a better user experience. We all want to upgrade to bigger and better screens that provide us with more immersive sound. Since these TV screens are expensive, not everybody can afford it. People who wish to have a better TV experience but do not want to spend a lot; we have good news for you.

With the advent of bias lighting, you can improve your TV’s power consumption, colors, contrast and black levels without having to spend a lot. This trick will work on any TV and will simultaneously reduce eye strain.

What Is Bias Light?

Popularly known as bias light, this light is adjusted behind a computer monitor or TV screen to provide an ambient light on the sides of the screen without hitting the user's eye. This improves the contrast ratio of your screen. It also reduces the eye strain that is caused by changes in the brightness of pictures that occurs during games, TV shows, movies and browsing.

Bias lighting is invented to improve the performance of your TV screens. This technology is not only limited to modern computer monitors or TV screens but it works on every size and every model. Despite all advantages, a bias light is very affordable. It can be installed very quickly. People who have a USB port in their TV can plug it into it. It powers your light and also gives you the option to switch it on or off. They come with a remote control which makes it easier for viewers to control it.

In some cases using bias lighting can negatively impact the situation. The light adjusted behind the TV gets so bright that it darkens the display on the TV screen. In such a case, viewers can dim the light as per their preferences. However, some LEDs face a color shift when they experience dim light, so it is recommended that you look at the specification carefully before buying it.

How Does Bias Lighting Improve TV Performance?

Bias lights are known to improve the overall performance of TV screens and these are some of the points that will prove it:

1. Increasing the Contrast of Your Screen

You may think that adding lights at the back of your screen will have the same effect; however, it is not true. Placing a bias light behind your TV screen will improve the picture quality, without having any extra glare. It does not only improve the picture quality but makes your TV have a higher contrast.

These lights do not increase the contrast but it creates an environment which allows your eyes to see better contrast.

2. Improving the Screen's Color

Humans use receptors to detect colors. These receptors are called cones and they only allow humans to see 3 limited colors- red, green and blue. The rest of the colors are a blend of these colors that are interpreted by our brain. Once it interprets correctly, you are able to see the original colors. This process works fine most of the time but sometimes it faces issues.

To counter these issues, bias light makes an unchanging and solid light behind the screen which is used by your brain as a reference. This will improve how you see colors on screen.

3. Selection of Color Temperature

The color temperature plays an essential role when it comes to improving the TV performance using a bias light. The color temperature of this light sets a reference point which determines how the brain will perceive colors. There are two types of lights- cool and warm. The warm side will have orange and red tones, while the other one will have blue tones.

Both of these lights give off different vibes. Warm lights create a calming atmosphere, while cool lights make it livelier. You can choose any light according to your preferences but it is recommended that you match the temperature used by the manufacturer of your computer monitor or TV screen.

4. Less Eye Strain

When you watch TV or use your computer monitor, you tend to stare a lot at the screen. This screen is usually surrounded by a black area which makes you focus at it with greater intensity. Your eyes perceive the screen to be extremely bright as compared to the environment of the room. They do not adjust to the light displayed on the screen but the light that is present in the rest of the room. This will neither allow you to see the actual colors and nor will you be able to perceive a clear contrast on screen. 

Another problem that comes with it is that watching TV with dark surroundings makes your eyes fatigued.

Unlike other lights, a bias light does not increase glare and decreases contrast. It is placed at the back of the screen and illuminates its surroundings without shining towards the screen or into your eyes. Since the light does not originate from the sight line of the user, it illuminates the room without shining directly into your eyes. This improves the performance of your TV screen and provides you with quality screen time without creating any issues for you.

Final Thoughts

Bias lighting is a technology which is made to enhance the performance of your TV and provide you an amazing screen experience. Apart from its aesthetic look, a bias light provides you enough light that illuminates the surroundings of your TV screen or computer monitor. This mitigates the darkness and enhances your experience. A bias light improves the contrast and colors of the screen. Along with this, it also decreases the chances of eye strain.

Some people may choose to switch on a lamp or ceiling light and think that it will have the same benefit as a bias light. However, it is not true. Using light through other sources will hit directly at your viewing surface and add glare to the display of your screen. This increases your chances of eye strain and weak eyesight.

Using bias lighting will make your experience enjoyable and comfortable. The texture will appear richer and the colors will pop out better.
