I have an Optoma HD65 that has been working well for quite some time. Today we decided to add digital cable into the mix and we're having a problem.
The digital cable box is hooking up with an HDMI cable. We have been using the cable and the HDMI port for our DVD player for months with no problems. The cable guy tested two different boxes and the projector is not detecting the signal from the box. He then took the box upstairs to our regular flat-screen and it worked just fine through the HDMI port. So it's not the box, it's not the HDMI cable and it's not the HDMI port on our projector.
What could it be??? Is there a setting that I'm missing?
HELP!!!
