If you are using modded inf to install new workstation (180.x) GeForce drivers to a notebook (from for example <a href=\"http:\/\/laptopvideo2go.com\/\">here<\/a>), brightness control via function keys will behave strange. Strange as in &#8211; it won&#8217;t fade at all or will fade, but in strange steps. You can notice hard screen flickering when dimmed.<\/p>\n<p>Solution is to add this to nv_disp.inf:[ftf w=&#8221;490&#8243; h=&#8221;130&#8243;][nv_SoftwareDeviceSettings_G8x]<br \/>\n&#8230;<br \/>\n;Smart Dimmer Controls<br \/>\nHKR,, EnableBrightnessControl, %REG_DWORD%, 1<br \/>\nHKR,, PanelPWMFrequency, %REG_DWORD%, 210<br \/>\nHKR,, PanelPWMDutyRange, %REG_DWORD%, 0x03E80096&#8230;[\/ftf]<br \/>\nWhen I first noticed this behavior I thought that my laptop is dying in slow and horrible death. I updated really old drivers packed with laptop with new modded ones. Late in the evening I use to dim my screen a bit, but after driver update brightness control via function keys would fade the screen in such a nasty way which definitely reassembles laptop screen dying. Beside the brightness problem, the Powermizer would dim the screen to black (instead of a very dark but visible setting), and screen wouldn&#8217;t lit up after laptop has woke from stand by.<\/p>\n<p>New modded drivers didn&#8217;t contain above three laptop manufacturer specific settings and that caused all the problems. It&#8217;s also interesting to note that brightness control in Vista&#8217;s original VGA driver works flawlessly. So to completely rule out hardware failure, test your screen with those drivers. <\/p>\n<p>Each time I update drivers in such a manner, I am happy that my hardware doesn&#8217;t melt. And yes, I&#8217;ve tested above settings on Samsung and Asus laptop and brightness control worked as with original driver set. Hooray! )<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This is rather note to my self then a post.
