Iam unable to adjust screen brightness in windows7


are you pressing the Function key first? the brightness buttons do not work without pressing that first. usually it is in blue close to the ALT.
& Win key
You can also change your brightness from the control panel, click on display then color setting, and you can see the contrast and brightness, as well as gama that does make it brighter or darker as well. Remember to write down the default settings.
these will not affect playing movies, the brightness adjustment for that are different controls, they can be access by the right click on the mouse during playback

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 ( ).

http://windows.microsoft.com/en-US/windows7/Calibrate-your-display#

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

Samsung monitor menu controls (contrast & brightness) inoperable


You're not supposed to be able to use the mouse to adjust these settings. These settings can only be adjusted from the buttons on the monitor!

Please read the user manual for your monitor for exact instructions.

How do i adjust brightness in hp g60


Here's how to adjust the screen brightness for a laptop in Windows 7:
  1. Go to Control Panel -> Hardware and Sound -> Power Options.
  2. Click on "Change plan settings" for your laptop's selected power plan (either Balanced or Power saver).
  3. Now edit your plan settings by moving the sliders next to "Adjust plan brightness" at the bottom. You'll be able to change the brightness for when your laptop is On battery power, or when it's Plugged in.
  4. Once you've adjusting the brightness settings to your liking, then click on the 'Save changes' button.
Alternatively, here is another way: From the Windows desktop, hold the fn key and press the f7 key c00776226.jpg to increase or the f8key c00776225.jpg to decrease the brightness of the display. If using the function keys does not resolve the problem and you have a Lid Actuator on your particular model, check the movement of the Lid Actuator switch to determine that it moves freely and is not stuck. NOTE: The key numbers (f7 or f8 ) may vary depending on the notebook PC; however, the images on the keys should be similiar. If you reboot the PC after using the function keys to change the LCD brightness settings, the brightness may return to the default setting on some models, which is based on the power source-battery or AC. This is not an error. The notebook is functioning as designed. If the notebook returns to the default setting after rebooting on your particular model, use the function keys to change the brightness back to the desired settings.

My laptop display very dim


If your HP laptop has a dull screen, or if the screen is too bright to make out anything that's displayed, you may need to adjust the brightness to get your screen back the way you like it. You don't want to strain your eyes to see your screen, and the fix is really simple. It's about as easy as adjusting the brightness on a TV. You'll have your brightness set the way you want it in a few seconds.

1. Right-click on an empty space on the desktop and a drop-down menu will appear.
2. Click on "Properties." If the HP laptop uses Windows Vista, you'll click on "Personalize."
3. On the "Personalize appearance and sounds" screen, click on "Window Color and Appearance."
4. Click on the arrow beside "Show color mixer."
5. Use your mouse pointer to move the tab on the "Brightness" scale to the left or the right to adjust the brightness and click on "OK" when you're content with the color.

I hope you find it very helpful. Thank you for using fixya.

Best regards.

Is there any way to brighten my screen on my acer aspire 5601 lap top


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).
