reducing the screen light cause the dimmed light to pulse

Research +

Hi Mayer,

Thanks for your quick answers. Unfortunately, i red all the forums on the internet and people seems to mistake 2 things :

1- screen blinking (Some parts of the screen start to flash very quickly, this is a software issue and can be addressed via software update)

2- screen light pulsating (when users reduce the screen backlight to increase battery life, the light start to pulse like we are in a disco party, making our eyes go crazy)

i have problem number 2 : the pulse effect.

Symptoms :

a) On OSX, when using the geforce 9400M GT, i experience the problem very very slightly, but it does happen

b) ^&%% begins when i use the 9600M GT. When the backlight is set to 1, its a disco party on my screen. I have to keep it at minimum 4 to get a good result.

i also noticed that the screen light starts to panic when :

- i am in different room

- Light ambiance is different (day vs night)

- When i use the integrated mouse on my macbook pro (i mean, that if i move the pointer on the screen, its starting to accelerate the problem even more).

i did all the software updates in OSX and in Windows 7 (64Bit) bootcamp (version 3.1)

Nothing i have done or read over the internet has helped me so far.

Personally, i think its the entire screen or the inverter as you said in your early post.

What should i do ? if iFixit can help me, i am willing to do business with you.
