Monitor trable display have no of horizontalline and brightness increasing

Shannon Wagner.,
You can try increasing the brightness using the FN keys on your keyboard. <Fn><F11> Decreases brightness on the integrated display only (not on an external monitor). <Fn><F12> Increases brightness on the integrated display only (not on an external monitor). If needed start the computer and tap the F2 key to enter the bios. Navigate to the Video Section and you will see where to adjust brightness.
LCD Brightness This option (represented by a slider bar for On Battery and On AC) sets the panel brightness when the ambient light sensor is off. Thank You,

he Dell I'm using also has an adaptive brightness, regardless of the fact it does not have a light sensor. It just changes brightness of the screen depending on how much white/black is shown at that moment. Whenever I switch from a very dark to a very bright website I notice and increase/decrease in screen brightness. I'm running Windows 7 by the way.
Good Luck

Occasionally, you may find your laptop's monitor is too dim for your liking. A normal desktop computer's monitor has an on-board menu system that lets you adjust the brightness and picture control settings as you please. A laptop monitor has no such controls. You can adjust the brightness of your laptop monitor using your laptop's keyboard.

1.Press and hold the "FN" key on your laptop's keyboard. This is the "Function" key, which operates much the same way that the "Shift" key does: It allows keyboard buttons to be used for multiple purposes. It's located in the lower left corner of most laptop keyboards, next to the "Windows," "CTRL" and "ALT" keys.
2.Look at the top row of keys on your keyboard for a key with a tiny triangle pointing upwards and the symbol of a sun on it. This is the "Increase Brightness" key. With the "FN" key held down, press the "Increase Brightness" key. On most laptop keyboards this is the "F7" key, but it varies depending on the model.
3.Continue to hold down the "FN" and "Increase Brightness" key until your dim laptop monitor has reached the level of brightness you require. A laptop monitor can only get so bright. It will stop at its highest setting.
4.Release the "FN" and "Increase Brightness" keys. You have now fixed your dim laptop monitor.

I hope you find it very helpful.
