C120 Projector display not smooth

Question

My new C120 projector's display is not flowing, or you could say the refresh rate is low. It's not only the video but also in the desktop the mouse moves slowly. Simultaneously on my laptop display I can see the movement smooth as normal. What may be causing this?

I'm using it with an Acer Aspire One netbook, with Windows 7 Ultimate installed with all updates also on the AMD Radeon 6250 video card. I have installed the projector's software which runs automatically each time I plug it in and sets the display to 800x600i have tried all display options already  but I also tried all other display modes. None works.

And when I go to Acer support it says both my SNID and Serial numbers "does not appear to be valid."

What can I do?

I am having the same problem with the c120 video displaying slightly lagged and choppy. This is through a usb 2.0 port. The cpu on the pc is not labouring so I can only assume it has something to do with the port speed not being 3.0. I will have to send it to a shop and have them do trials on a machine with a 3.0 port.

Hi

I gather you need USB 3 for smooth flow.

My notebook only has 2 so video choppy.

Static display fine.

Haven't tried it on my desktop usb 3 yet.
