HOW TO SET BRIGHTNESS OF THE SCREEN? - Computers & Internet

If the picture mode is set to Cinema or Custom, the screen could become dark. If the screen is still dark after the picture quality mode has been changed, change the setting Backlight, Picture, Brightness and adjust the brightness to your taste. ... Depending on such settings, the picture brightness level can be higher or lower

Sounds like your keybinding/hotkey combo is not doing its job. (or your bulb in the display is going out)

You can open up Control Panel and adjust brightness from there.

Step 1 Click "Start ' Control Panel ' Hardware and Sound ' Power Options" to open the Power Options window.
Step 2 Click and drag the bottom "Screen Brightness" slider to the right to increase screen brightness and to the left to decrease it. Making this adjustment changes the brightness level only for the current power source; if you change power sources, the screen brightness may change again.
Step 3 Click "Change Plan Settings" on whichever power plan is currently selected.
Step 4 Click and drag the "Adjust Plan Brightness" slider to the right to increase brightness for each of the power sources, such as "On Battery" or "Plugged In." If you want high-precision numeric control, you need to access the advanced settings.
Step 5 Click "Change Advanced Power Settings."
Step 6 Click "+" next to "Display" and then "Display Brightness" to expand these options.
Step 7 Click "On Battery" and enter a percentage in the field provided. Choosing "100" will set the screen to maximum brightness; any other brightness will be a percentage of the maximum brightness. To increase the brightness, make sure the number you enter is higher than the current value.
Step 8 Click "Plugged In" and set its brightness percentage.
Step 9 Click "Apply" and then "OK" to close the Advanced Settings window.
Step 10 Click "Save Changes" to save any changes you made on the Edit Plan Settings page. If you only make changes in the Advanced Settings page, the Save Changes button will be grayed out. If that's the case, just click "Cancel."


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.

1. go into the menu and pick deguass

Check your inverter, it's possibly going bad or loose connection

OPC_ Optical Picture Control
Automatically adjust the brightness of the screen.
You can change the settings in the menu option.
It's in Menu, then picture, then OPC.

OFF- The brightness is fixed at the value set in "Backlight"

ON- Automatically adjusts

ON: DISPLAY- Displays the OPC effect on the screen while adjusting the brightness of the screen.

If you don't want the silly display from popping up all the time, go into to menu and change the setting to ON; instead of ON: DISPLAY

try using the fn key and the brightness keys at the top of keyboard
