Screen flickering

[willem]

I have a sony VAIO VGn_RN11 with windows vista home premium 32 bit.
Next to this laptop i am using a secondary monitor (22" Samsung syncmaster
2232BW) The laptop has a Mobile intel 965 express chipset family graphic card.
When I connect the secondary monitor to the laptop, he monitor starts
flickering... I can see horizontal flickering stripes, that go from the
bottom to the top of he screen. I believe this is obviously a frequency
(refresh-rate)-problem, but i cannot change the refresh rate in the display
settings. I can only select 60Hz
The flickering doesn't have anything to do with any other devices, cables,
or something like that, because when i connect it to my iBook it doesn;t
happen, when i connect the secondary monitor i use on the iBook (same
samsung) it flickers.

I have tried several drivers (windows, intel and samsung) for the monitor
but the flickering stays.

The only time the flickering was gone, was when i did a hard power switch
off, that forced the computer to do a check up. Right after this check up,
the flickering was gone, but gradually came back.

anyone knows what's the cause and the solution to this problem?

Try using digital cables or really good (analog)VGA cables. I had basically
the same problem you did. The digital cables solved my "flickering screen"
problem. I was using VGA cables supplied with a new Samsung 24" monitor.
Great monitor cheap cables.
