Do you know of any tool for Windows that let me adjust the backlight brightness of a monitor?

If it is a notebook, you will have a combination to press example FN + F4 - birgher, FN + F3 dimmer. If it is a stand alone monitor.. the only way to change it is via the MENU options on the Monitor.. if its not there.. then there is no other way, but to boost the brightness and/or contrast on the graphics driver. – ppumkin Jan 23 at 13:45

Are you talking about an external monitor or a laptop's built-in display? An external monitor's brightness is almost always controlled externally by the monitor, there just isn't any way to pass brightness settings information over any of the usual display connectors (VGA, DVI, HDMI, DisplayPort, etc.). A built-in display on a laptop or all-in-one however has its brightness control integrated with the system, and can be controlled from within windows by some software. The actual software to do so will depend on the manufacturer. Windows 7 can do it automatically from the Windows Mobility Center (press Win+X), but in Windows XP you will need the manufactuer's drivers.

I ask this because I know it IS possible. I use an external monitor with my laptop and in the configuration of my laptop's video card there is a sliding control that let me adjust my EXTERNAL monitor's backlight. Unfortunately, I have to do about ten thousand clicks through the GUI only to reach that sliding control. Simply not practical. – GetFree Sep 11 '10 at 5:51
Interesting. Sounds like it might be specific to the video card's drivers then... I've never seen anything like that before. – nhinkle♦ Sep 11 '10 at 6:04
Me neither. The drivers config dialog box says "Intel Graphics Media Accelerator Driver for mobile" and my external monitor is a Dell 2007FP – GetFree Sep 11 '10 at 6:24
@GetFree Not possible that your laptop controls the backlight of the external monitor.. it must be imitiation, or using a gamma reduction on the driver, to immatate the brightness on the external one. Can you proove that the backlight setting has been turned down? by looking at the stetting on the monitor?? I can bet 10 bux its driven via Drivers and not hardware.. – ppumkin Jan 23 at 13:47

@ppumkin, believe me, it's not emulated via color change or gamma reduction. It really does change the backlight brightness. My best guess is that it must be a propietary mecanism from Dell, since both my laptop and external monitor are Dell. – GetFree May 19 at 10:34

The application Display Tuner can control the brightness for many different LCD/CRT monitors.
However, if backlight is a separate setting on your monitor, you might be out of luck.

  • If you use an Nvidia Graphics Driver (Resource from here )

  1. Right click on desktop and select NVIDIA Control Panel

  2. Click on “Adjust desktop color settings” at the left hand side navigation bar.

3) Select NVIDIA settings and you can now move the slider for Brightness and Contrast.

That doen't change the monitor's backlight but the image brightness. – GetFree Sep 11 '10 at 6:31
Hmm, I think you are right, I removed from my answer – subanki Sep 11 '10 at 6:36
please update your answer, as this does not control the backlight, but the drivers based contrast/birghtness/gamme.. it is off topic.. I rather up vote you than down – ppumkin Jan 23 at 13:48
