I have been connecting my ACER projector to my HP laptop using a HDMI cable without any issues for the past few months. 
However, now when I try to connect it I get the message "Input not supported".

The projector connects fine to other laptops but my laptop no longer supports it.
Any advice would be appreciated, thanks.
