I have an ACER Aspire ES1 500 series Model N15C4.  I have recently purchased an (unbranded) projector.  The laptop only has a HDMI output but I cannot get the laptop and projector to connect.  The laptop works with other devices and so does the projector but not together e.g.

ACER Laptop via HDMI to TV – working

Playstation3 via HDMI to projector – working

Old Dell laptop via VGA to projector – working

ACER laptop to projector – project displays “wrong format”

Any ideas?
