HOW TO SET BRIGHTNESS OF THE SCREEN?


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....

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.

TV shuts off with high color images . Example: explosions,bright lights etc


Normally, the screen control being up a little to high, would cause this problem. If no one has worked on this unit when it started may be a sign of something else, for example, the 200 volt line may be running a little low. Check the brightness and contrast for starters and if that doesn't help, then, the screen control would be my next step. Hope this helps.

picture adjustment questions


*The brightness control setting determines how bright your picture will be. *The contrast control sets the gain of the video circuit. This determines the difference between dark and light scenes. Low contrast settings make the picture "hazy". High contrast settings make the picture more distinction between dark and light scenes. *The sharpness control determine the frequency response of the video circiut. High sharpness settings give better resolution but also shows more noise in your picture. Lower sharpness settings smoothe out the picture removing noise but also fine detail. It needs to be set for the best all around picture. *Picture Enhancement is pre-set adjustments which give you different picture qualities. You just select the one you like. Stargazer
