BRIGHTNESS CONTROL I CAN NOT REDUCE THE BRIGHTNESS IN THE SMALL DISPLAY WHEN THE MAIN SCREEN IS INSIDE

If the display screen on your Boss MR1308UAB car stereo is completely black and you're unable to find a control setting for brightness, there may be a few possible causes and solutions to consider:

1. Check the backlight setting: Some car stereos have a separate setting to control the backlight or illumination of the display screen. Look for an "Illumination" or "Backlight" setting in the main menu or settings menu of the stereo. Adjust the setting to ensure that the backlight is turned on and set to an appropriate level.
2. Check the dimmer setting: Many car stereos have a dimmer function that adjusts the brightness of the display screen based on the ambient light conditions. Check if the dimmer setting is enabled and set to an appropriate level. If the dimmer is set to its lowest level or turned off, the display screen may appear black. Adjust the dimmer setting to increase the brightness.
3. Verify the connection: Ensure that the wiring connections between the car stereo and the vehicle's electrical system are secure. A loose or faulty connection could cause the display screen to appear black. Double-check the wiring harness and connections to make sure they are properly plugged in.
4. Reset the stereo: Try performing a system reset on the car stereo. This can help to clear any temporary glitches or issues that may be affecting the display screen. Refer to the user manual for instructions on how to perform a reset specific to your model.

Adjust your monitor's brightness and contrast

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.)

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.

Brightness and contrast symbols

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.

Laptop display. Laptop displays don't have brightness or contrast buttons on the front.

For a majority of laptops, there isn't a control for setting the contrast.

However, you can set the brightness of many laptops by pressing and holding the Fn key, and then pressing a function key to decrease brightness ( ) or increase brightness ( ).

When using Display Color Calibration on a laptop, set the display to the maximum brightness setting.

Adjusting brightness automatically using adaptive brightness

Adaptive brightness is a feature in Windows that uses a light sensor to automatically adjust the display brightness to match the lighting conditions in your computer's surroundings.

To use adaptive brightness, you must have light sensors installed and enabled on your computer.

To determine if your laptop or computer monitor supports adaptive brightness, look for the Enable adaptive brightness setting in Power Options (mentioned in the following procedure) or check the information that came with your computer.

To turn adaptive brightness on or off

Open Power Options by clicking the Start button , clicking Control Panel, clicking System and Security, and then clicking Power Options.

Under any plan, click Change plan settings.

Click Change advanced power settings.

In the list, expand Display, and then expand Enable adaptive brightness.

To turn adaptive brightness on or off when your computer is running on battery power, click On battery, and then, in the list, click On or Off.

To turn adaptive brightness on or off when your computer is plugged into an outlet, click Plugged in, and then, in the list, click On or Off.

Click Apply. Click OK.

hope this helps

Examine the keyboard. There should be a symbol on most of the function keys (F1, F2, etc.). Look for one that looks like a sun or lightbulb, either with an arrow pointing up or with the sun/lighbulb filled in. Hold the 'Fn' key, and tap the up/bright sun/lightbulb key a few times. The screen should increase in brightness.

If you cannot find the specified keys, you may be able to adjust brightness from inside Windows. Right click on the battery icon in the taskbar and open 'power options'. Look for a sun and moon with a sliding bar between them. You might also be able to adjust brightness by customizing your desktop (right click on the desktop and look for the proper menu).

Actually, the problem isn't with the drivers. Right click on the battery icon in your system tray. Select "Power Options" (NOT Power4Gear eXtreme). On the right panel, select "Adjust the display brightness." Then, select "Change advanced power settings." Scroll down and open up the "Display" box. The options that are affecting your screen brightness on battery are "Allow SmartDimmer to reduce my brightness after," "Have SmartDimmer reduce my brightness by," and "SmartDimmer full-screen video mode." Playing with the percentages in these boxes will affect how your screen brightness adjusts itself. To get my screen to stop re-brightening itself, I changed "Allow SmartDimmer to reduce my brightness after/ On Battery:" to 100%. I then changed "Have SmartDimmer reduce my brightness by/ On battery:" to 0%. Finally, I set "SmartDimmer full-screen video mode/ On battery:" to Maximum Power Saving. This should solve your screen-rebrightening problems even with the 163.44 drivers (I use those too). Please Rate.

Bootup your computer and display your Windows Desktop. Make sure yourmonitor stays on for at least half an hour before you begin, so that itis properly warmed up.


Seta pure black image on the monitor so you can adjust the brightness. Toget a pure black image, do the following: Choose Start, then ControlPanel, then Display. This will open the Display Properties dialog box.Click the down arrow next to the representation of the desktop color inthe Color field. Choose black from the color palette, then click OK.


Maximizethe Brightness control on your monitor, then slowly reduce it until theblack of the image perfectly matches the black at the edge of thephysical screen. This puts the brightness at the proper setting.


Open a screen with a plain white background soyou can adjust the contrast. One of the best ways to do this is to open aword-processing document without any text in it. Gradually reduce the contrastsetting of your monitor until the white area of the screen begins to lookslightly gray or off-white. Then gradually increase the contrast until thewhite area on your monitor is pure white. This will give you the proper whitebalance. Now you've got your monitor ready for peak performance.

Hope this may help you solve your problem.
