Hi all,

I am currently experiencing flickering on my external monitor, connected via VGA from my laptop--flickering like a low refresh rate even though it is at 60 Hz. I have a Sony Vaio, model vpcsa490x. The laptop has switchable graphics cards and when I switch into the Intel 3000, there is no flickering. The flickering is only when I am using the Radeon 6630M leading me to believe its the graphics card's fault? I have the latest drivers installed so I don't know how to fix this.

Thanks for any help
