We have one very long run at our church to our front projector. We used the HDMI extenders that convert to Cat6 at the computer and then back to HDMI at the projector. The problem is occasionally the signal drops for just a second and the screen goes blank and then comes back on. It is very random but obviously is unacceptable. Can I use an HDMI repeater on the projector end to boost the signal? All help is greatly appreciated! we used the same method for our rear projector but that cable run is shorter and it has no problems.
