connecting to OHP


New Member
I want to connect my Laptop to an OHP for presentations. When I use a 1.5m cable to connect the VGA Output to the OHP everything works fine. When I use a newly purchased 5m cable I have a Problem. Every time I click the mouse the projected Image disappears and the message "Auto-Setup" shows on the Screen. After a few seconds the projection re-appears, until I click the mouse again.
Is there a fault in the cable (how can I test for this?) of have I missed some important step during the Setup?
