Vista Business with dual screens

[Richard Thompson]

I`ve noticed a problem on a couple of my Vista machines when a secondary
monitor is attached. I am running Vista Business at my company on 3
different Lenovo notebooks and when I unlock my machine the screen seems to
blink a few times before settling down back to normal.

Initially I thought it was due to an inferior screen card but then noticed
the problem on a much higher spec notebook. I`ve tried the following:
- changed the resolution on both monitors to match,
- changed the refresh rate to match,
- disabled Aero,
- optimized for performance,
- remove any desktop backgrounds, etc
- updated my display driver to the latest driver revision

None of these changes have made any difference regarding my specific
problem.

An interesting note, my Dell notebook which has a lower spec than the
Lenovos works perfectly with both the standard out the box driver and the
latest Dell driver.

Any suggestions welcome,

Richard

You can turn off the feature for User Access Control temporarily (in user
accounts) and you would see that go away. I recommend that you tolerate the
blink.

Hi Mark,

UAC is already disabled on my machine, still blinks!

Kind regards

Are you using Presentation Director to change screen mode? Fn + F7. Have
you tried making a fresh scheme, or tried others?
