My Optoma DX607 will not sync up with the laptop.
Hey
Noting wrong with your projector, its a simple settings issue on the laptop, you need to enable the external video output, on the laptop, you need to hold down the FN button and then press one of the F1 to F12 keys, sometimes its FN+F8 or F5, F4 you need to look at the keys, one of them will have a icon of a display or two or two boxes or similiar, if noting else, try them all.
When you find the button you may have to press it a few times to cycle over the different settngs such as, laptop display, laptop display + external, external only etc.
that should do it, you can also right click on the desktop and select properties, and then settings, on the settings page right click on the display 2 and select attach. that should also give signal to the external output.
let me know if you need further assistance.
