I have a bit of a strange issue. A standard Smartboard which was running ok but since I have put a Lenovo ThinkCentre on it with Windoes 7 OS the repeated image is not showing the top of that which is shown on the monitor. However, thatv said when a DVD is run it's fine.
The BIOS was set bwrong on the PC so I changed that but it's made no difference to the output to the Smartboard. Any ideas or suggestions on this one please?
