After Upgrade to win 8.1 I CANT control my screen Backlight

 

In the windows settings it is set to 100 %

But in real life is looking like its set to 50 % max

 

if i want to lower the setting screen is staring to blink 

Backlight on, Backlight off and repeating

if i go lower its staring blinking faster

 

i think thats becouse newer version of amd catalyst does'nt support this laptop ?

 

It there any Backlight Driver for win 8.1

 

My Computer Info :

 

Acer Aspire 5738Z

ATI / AMD mobility randeon 5650 HD 

Driver : AMD Catalyst 15.20

Pentium Dual-Core TT4400

Windows 8.1 64 BIT
