Asus N75sl. Flicker by HD3000.

luftoder said:

I have an ancient problem, which I had always on my Asus N75sl and which I cannot solve till these days.

It is Monitor-flicker. It is like the monitor works on 50Hz instead of 60Hz. Especially good is the flicker seen, if you look at gray color.

Some idea or suggestion would be very helpful for me.

Asus N75sl specs:
Intel HM65
i7-2670QM
HD3000/GeForce 635m (optimus)
ALC663
Clover (UEFI)

ok, now I know at least, that nothing can be done to solve the issue. Thanks for tip, next days I will solve this issues.
Just one more question: on this laptop I have additionally a small subwoofer. Is it theoretically possible to get it working?
