TV Contrast Problems
Contrast is a concept of luminosity that represents and displays an image in a more distinct manner. The ratio between the brightest color and the darkest color that a television or a video projector can produce is termed as the contrast ratio. A high contrast ratio is generally what viewers want to experience in a display. However, even though it’s stated that the TV contrast ratio is same for every model, there is no standard measure for it and therefore, the actual contrast tends to vary from model to model. Below are frequent asked questions on issues relating to TV Contrast Problems that has been answered by the Experts.

How can I adjust the contrast on my Sharp TV when there is no menu button on my SystemLink RCA remote?
Usually, a universal remote can perform some basic functions on your TV but not all of them. Therefore, in case you see that your SystemLink RCA remote is not functioning or you are unable to activate the menu through this remote or you have tried using all the codes listed for your remote, it means your remote could be universal and is unlikely to work in this case. Thus, in a situation like this, you would need to have the original remote to the TV in order to have access to the menu button for adjusting the contrast level on your Sharp TV.

What would one do if there is a prompt saying to use the “User Mode” to adjust the TV contrast, even though the original remote to the TV is being used?
In most cases, you would find that almost every TV remote has a button on it that is used for changing the preset picture settings. However, these buttons are named differently that varies from model to model. For instance, they are called AV Selection on Pioneer TV sets. Usually, when you push these buttons to change the picture settings, the options that you get are Movie, Standard, Dynamic, Game, User and so on. In some cases, however, you could change and adjust the color, contrast or the brightness of the picture, only if you are customizing these picture control features through the ‘User Mode’. This is because these modes are restored in the factory settings. In your case, you would therefore, need to get to the ‘User Mode’ to be able to adjust the contrast on your TV.
Even though contrast ratio is an important specification in modern televisions and the manufacturers boast about having impressive contrast ratios in their televisions sets, there are many TV contrast problems that viewers face. These problems may relate to issues like excessive backlighting in TV’s, poor contrast ratio in the picture, presence of rainbow effect and so on.
