Q: The screen switching worked well enough. Not too many choices that have both DVI and VGA. However the operation of the keyboard/mouse was very choppy - virtually unusable. I am using a Microsoft wireless keyboard and mouse. Didn't matter if it was plugged into the keyboard port or the generic USB port. Also, when trying to sync an iPhone it would say disconnected halfway through. No choice but to return it. Going to try a ConnectPro setup, which is certified to work with my keyboard/mouse, but does not provide audio switching, which I don't need anyway.
A:
USB Not Right
