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....

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

You can get user manual here:

Try going into the control panel and select power options see if there is way to adjust the display brightness or try holding down the "Fn" key and use F7 to increase the brightness

Does this monitor have an OSD (On Screen Display),
and a button to activate the OSD?
Does the OSD have the capability to adjust the brightness?

Have you tried to adjust the monitor brightness? There is a function in the menu for Monitor Brightness that will allow you to make the LCD display lighter or darker. Go to Mode Menu and then down to Setup tab and then to the icon for Monitor Brightness (page 88 of the advanced user manual explains how to set this up).

Find yourself a dark room or wait for the night to come. The darkest monitor adjustment could somehow reveal some light when there are no other light source available.

You may also hook a conventional CRT monitor and make your changes (such as bringing your computer back to its original settings). The darkest adjustment in CRT monitor could still render discernible displays.

Brightness is adjusted by using the 2 buttons on the left side of the front.
