Mavericks - USB to HDMI Monitors I'd like to update to Mavericks on my "mid 2012" MBP, but am worried about my monitor setup. I have two Samsung S22C300 Monitors attached to my computer, one via a thunderbolt to HDMI adapter, and the other through a Cable Matters USB 3.0 to HDMI adapter which has drivers only updated to Snow Leopard, but they work ok on Mountain Lion (with a little monitor lag, but I've gotten used to that). 

Has anyone had an issues with their "third" monitor with the new MacOS? More specifically, any issues with connecting monitors to USB with the Cable Matters adapter?
Nothing that I have run into personally but I just ran across this:

Which indicates major issues witht he author's USB monitor (DisplayLink) so I would not upgrade untill you are either sure you have updated drivers or can do without your second monitor.
