How to adjust contrast on the avaya 6424d+ screen

The ST651 display adjust settings will vary depending on the specific model of your display, but generally, the settings that can be adjusted include:

1. Brightness: Adjusts the overall brightness of the screen.
2. Contrast: Adjusts the difference between the lightest and darkest areas of the screen.
3. Color temperature: Adjusts the color temperature of the screen, which affects the overall color balance.
4. Gamma: Adjusts the mid-tones of the screen, which can affect the overall contrast and color balance.
5. Sharpness: Adjusts the sharpness of the edges of objects on the screen.
6. Overscan: Adjusts the size of the image on the screen, allowing you to zoom in or out to fit the entire image on the screen.
7. Aspect ratio: Adjusts the proportion of the width and height of the image on the screen.
8. Color format: Adjusts the format of the color on the screen, such as RGB, YCbCr, and so on.
9. Audio settings: Adjust the volume, bass, treble and audio output settings of the display.

You may find these settings in the on-screen menu of the display and you can use the remote control or buttons on the display to access and adjust the settings. Some settings may not be available for certain models, and it's worth consulting your display's user manual for specific instructions on how to access and adjust the settings on your particular model.

Hi,

Dear User...

You can adjust the brightness and contrast of your monitor to improve the readability of text and to make digital pictures appear more like they'll look when printed.

To improve the results when adjusting the brightness and contrast settings for your display, use Display Color Calibration. (Display Color Calibration helps you adjust these color settings and others.) For more information about calibrating your display color in Windows, see Calibrate your display.

The way you adjust brightness and contrast varies and depends on your specific display.

• Brightness and contrast buttons on the front of the monitor. Some monitors have brightness and contrast controls on the front and use the standard symbols shown in the following image.

• On-screen menu. You can change the brightness and contrast settings for some displays by using an on-screen menu, and then setting the brightness and contrast in the resulting menu. Many times, you can view the on-screen menu by pressing a button-possibly labeled Menu-on the front of the monitor.

Thanks....
