Blinking & No Rotation- B3 & OS X 10.7.1

[greenkiwi]

Hello,

I have the MonoPrice USB2 Display adapter that goes to 2048x1152. I have it connected via DVI to a Dell 20" monitor. I've installed the software and everything works.

After about 3-5 minutes, the screen starts blinking on and off.... on and off... on and off. I sometime have a crome window with Gmail loaded on that monitor, if that might cause issues.

I also cannot get rotation to work with the default mac software, so I am currently using SwitchResX to allow for rotation. (though it blinked even more rotated, so I have unrotated my display.)

A final problem that I've see is that when switching spaces it sometimes goes blank.

Could you please the debug tool here http://www.displaylink.com/support/ticket.php?id=269 and post the output file? Thanks

Will do. Do you want me to get it into the "blink" state and then grab the info?

Here's the log, thanks for the help.

Did that contain the information you needed? Or do you need more?

Thanks for the logs. We haven't identified the problem yet. Did you captured the logs during the blinking state? If not could you please get into the blinking state and capture the logs again (reduce the verbosity to DEBUG)? Could you also temporary uninstall the gfxCardStatus app before capturing the logs? Try also to change the display arrangement (move to the left or right of the internal screen) and see if the problem is still there. Thanks

your screen will blink if you're in Better Battery life (the nvidia 9400 chipset) versus the better performance (the 9600 chipset) under energy saver in system preferences. I hope this helps you.

My system is using discrete graphics (set to always use and not dynamically switch). And it has the ATI card in it:
AMD Radeon HD 6750M 1024 MB

Btw, I'm only using the external display via DisplayPort at the time, not the internal display.

Is there any more debug information I can collect for you?
