Thanks a lot, worked like a charm, my brightness is much better now,
a few more things i would like to know, whenever i want to change the data, do i have to do it through the script and reinstall the kext, fix permissions, rebuild cache and reboot every time, or is there an easier way, I'm assuming i can fix permissions for just the installed kext right? I also want to know what is the lowest and highest values my panel can take and how to go about editing the values manually.
You can just edit your injector kext's Info.plist directly, then install via Kext Wizard again (repair permissions, rebuild cache, reboot). No need to run the script at this point.
With HD3000 (and HD4000) the range is 0-0x710. You will notice that the script generates right up to the max, where the built-in kext data from Apple usually sets the highest value at somewhat lower than that. Yes, most Macs are running with the max brightness less than what is possible. Notice that with the data I showed, the max was 0x64c (so 0x64c/0x710=89% of theoretical max).
The lowest value will depend on the panel... you'll need to experiment. When you use a value lower than what the panel can handle, you'll either get a flickering display or just black.
