CONTRAST ADJUSTMENT


it is best to shut the color level to the lowest setting then try t balance the screens to achieve the best black and white picture. then turn up your color level. Your brightness level should also be set to 50 % then when you adjust for the best B&W picture. You will have better color and brightness when you reset your color and brightness levels.

I am further looking into ur problem..

Goodluck..

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

I just had my Emachines D520 laptop display replaced because it was cracked. The new display is too bright, and the Fn keys that are supposed to control brightness don't work properly. When I use these...


Try going to control panel, then device manager, and try right clicking and updating all drivers that have to do with graphics or your screen. If this doesn't do the trick then try finding the display drivers manually.

Cannot change the brightness


to adjust brightness levels you might want to modify ONLY the brightness, contrast and gamma settings. Others might mess up your colors or god knows what. You can also set up the GPU's brightness settings by going to the gpu's control panel, usually opened by right clicking the desktop and selecting your video card's control panel option. Then adjust the brightness, contrast and gamma options to suit your needs. Hope that helps!

Monitor dims on a black background hanns G 28


Go into monitor settings and turn "off" X-Contrast. X-Contrast will auto change contrast when backgrounds darkens. However, adjust manually the Brightness and Contrast settings to compensate.

Brightness automatically going low when the brightness is at 100


hello, please make sure the magicbrite option is not set to "dynamic contrast" as this will change the contrast levels by itself, change the settings by pressing the down arrow touch key on the monitor, change it to any other setting, game mode is blinding on my one (when the monitor works, but thats another story!!!) good luck with samsung customer care centre 0870SAMSUNG (uk)

Green tint I can't seem to fix


Hopefully someone on here has a manual and can tell you exactly where the tint controls are. Also need to try adjusting the color level, turn it clear down so you have a black and white picture.
Is the picture still green over the screen with the color control
set clear down to black and white? If it does, you might
have an issue with the green gun going out or problem in the
circuitry to it.


By the way, the best way to adjust the picture settings on a
tv are to first turn the color control clear down, then adjust
brightness and contrast for best black and white picture, then
bring up the color level to where it should be and adjust the
tint for best red/green ratio.

Dark picture (HELP)


Open up the back of the set but be very carefull. Notice a large black block with a large red wire that runs up to the picture tube. on one side of that large block where the thick red wire is comming out of are two controls, one should be marked focus or F and one should be marked screen or S. With the set operating normally and not touching anything else, slowly turn the control marked screen or S clockwish till the picture gets bright enough. If you go too bright the set will shut down or you see small thin white lines so back down on the control. then touch up the focus and your good to go. good Luck.
