I can't decrease or increase my screen brightness

HAVING PROBLEM WITH BRIGHTNESS OPTION ON YOUR LAPTOP OR DESKTOP. The problem of brightness disappearing from your system is caused by two or more reasons which i will discuss here.

• Flex or LCD problem
• No Suitable VGA driver
• Unsupported Operating system

firstly:flex or Lcd problem.if your screen started encountering problem visible or invisible to you the user this might cause a technical problem which will result to effect to the VGA software configuration and might cause this error of not seeing the brightness setting option.likewise if your having a flex problem the same problem might arise... So consider contacting your hardware technician for fixing. No suitable VGA driver installed. Mostly the problem of not viewing or accessing this are mostly all because of no suitable driver for the hardware of the the system that works accurately with the operating system.Even if your VGA is installed,thats not a guarantee that you cant encounter this problem,By experience and knowledge of hardware in computer,when you are faced with this challenge, try to get the latest update of your driver providing if for your operating system and version,or you can choose to update the entire system which had greatly helped me to solve that issue severally. locate the company name or board processor company and request for a VGA compatible driver for your computer or update directly which is the best. remember after installation either the driver separately or the total update ,restarting is required for completion of its installations. Setting up. Many people choose to decrease the brightness of there light due to the effect it cause to our eye and its weakness and headache and power saving.many needs a proper setup that will suit there viewing ability and less consumption of power...locate your control panel,goto to display..goto adjust screen brightness and there you have the whole right to decrease the light to night level...or increase it to tough level...yeaaaaaaah ....or sun level... so i hope i tried to solve this problem.. if this worked for you,share it with other friends of sneakcode and other friends outside sneakcode .
