a lower capability for Windows 8?
I dont have this problem before when Im still on Windows 7 Pro.
He managed to solve this problem by installing NVIDIA graphics driver through his PCs manufacturer website.
He first downloaded the original NVIDIA graphics driver that comes with Windows 7 and then upgraded to Windows 8.
Installed the driver and the cable is now working.

Instead, you may hear your PC or laptop sound.
One of the solutions is to set up the latest Graphics media Accelerator driver from Intel.
