Connecting projector to computer for golf simulator and HDMI cable isn't working,

the cable works from a PC to a monitor but from the computer to the BenQ projector it doesn't transmit signal. I have tried projecting from a laptop to the projector with a shorter cable and the projector transmits fine. The cable is 75 feet long and I think the signal might not be strong enough for the projector but not sure. Any insight on this?
