Periodic blinking of Win7 display with external monitor

[Dabbler]

I've installed the 64-bit Windows 7 on my tx1410us notebook in a
separate partition while leaving the 32-bit Vista also on, though in a
much smaller partition than originally. Windows 7 installed a dual boot
loader, so I can boot into either OS. Then I attached a 23" Samsung
2333HD LCD monitor to it as an external monitor that also has a built-in
HD QAM TV tuner. Its native resolution is 1920x1080 at 60 Hz. The
notebook's GEForce Go 6150 graphics chip can drive the monitor at that
resolution with 32-bit colors. The external monitor's display looks
great except one thing: it blinks randomly, getting dark for about a
second and then everything is OK till the next blink. The notebook's
display blinks with the external monitor when they are set up in clone
display mode, both at the laptop's native 1280x800 res. However, the
notebook display does not blink when it runs without the external
monitor. There is no blinking at all in Vista WITH OR WITHOUT the
external monitor. I hope you could visualize my situation from the above
description.

It looks to me that the blinking in Win 7 has to do something with the
64-bit Nvidia display driver that was installed by the Win7 setup and I
wonder if anybody else experienced this problem and knows a way to fix
it.

Well this is just my opinion which might not mean much in this case, but
it seems most manufactures are having video card driver problems for
Windows 7 right now. I think we just have to be a little patient.

Well, I take your word for it. On the other hand, I hope posts like mine
help manufacturers to become aware of the problem.
