Interestingly enough, the 59Hz->60Hz switch DID cause my monitor to flicker momentarily, but after clicking OK, then going back to the Advanced settings again, it was back to 59Hz. Changing it to 60Hz a second time didn't cause the same flicker.
Weird.
I'll have to see if these settings stick...
First, thank you for posting this guide. It's been a big help... but I'm still not exactly where I want to be.
It seems the drivers didn't "take" after a second reboot and I was back at square 1, probably due to the drivers being unsigned =(
