手殘到nVidia官網下載新版的顯卡驅動程式給Mackbook air 2010 內建的nVidia Geforce 320M,
更新過程很順利, 開機進Windows 桌面時, 感覺"哇! 好亮眼, 新版驅動顏色表現差這麼多.",
操作一段時間後發覺不對勁?? 螢幕好刺眼?? 原來是亮度(brightness)全開產生的錯覺...
隨手按下F1降低亮度->沒作用, 按下F2->沒作用, GG了~
移除找回Bootcamp內建的驅動重新安裝, 恢復正常, 再灌一次官網新版, 又失效,
不死心的找Google大神求助, 沒想到還滿多討論,
最後找到一篇有用的:Geforce forums-Brightness controls not working
內文神人敘述到修改Registry來開啟brightness hot key control,
1) Open regedit and go to the "HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Class" key.
開啟regedit 及找到路徑"HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Class".
2) Find the sub-key corresponding to the NVIDIA graphics adapter. I did this by going to Find in the Edit menu and searching for "nvidia".
搜尋"nvidia"字串.
3) Add a new DWORD called "EnableBrightnessControl" and set the value to 1.
增加一筆DWORD設定字串名稱為"EnableBrightnessControl",並設定值為1.
4) Reboot and the brightness keys should work again.
重開機後亮度熱鍵可作用.
死馬當活馬醫, 衝了, 照著步驟做, 重開機後, F1/F2控制亮度熱鍵正常工作~
真是感謝神人~
如果有相同困擾的朋友們可以試試, 至少在我的Mackbook air 2010 nVidia Geforce 320M有作用.
