Epson Pro EX9240 not working with our HDMI Extender
Frank Cruson:
Crazy issue - Our ViewSonic projector that was 10 years old died. I replaced it with a Epson Pro EX9240 that is mounted on the ceiling and connected to an HDMI extender on the floor using a high quality Monoprice HDMI cable. The Epson Pro EX9240 works if i plug in a laptop directly to the projector with the long HDMI cable, but not with the Monoprice Blackbird 4K HDMI Extender! The extender source in is our sound booth 100' away. The extender works with the monitor on the stage floor, but not the projector. We never had this issue with the ViewSonic projector. Epson said the projector will not work with an extender, crazy. Any ideas?

SDI. Aja or Black Magic Designs converters.

If you are just needing a long HDMI run, Get a fiber cable for the full run. They're reasonably priced and work up to 300'.

Frank, end of day, HDMI isn't reliable over 50 feet. It's not designed to do it, to be really candid. SDI is the professional way of getting video over longer distances (and then fiber once you max out the transmission distance of RG6 cabling for SDI signals). As to why the extender works with the monitor on the floor and not the projector, very likely that the monitor is more tolerant of out-of-spec video signal than the projector is.
We're local to you in the PNW (Seattle) and if you want to try out some HDMI to SDI (and back) converters and lengths of SDI to see if tit'll fix your problem, let me know! I'd start by testing end-of-main-HDMI-run (that's plugged into the HDMI extender) with an HDMI to SDI converter there, and then using an SDI cable there to an SDI-->HDMI converter at the projector. If that doesn't work, then dropping an entire SDI run from source_converter to projector_converter. It may also just be losing clock sync, and a Decimator MD-HX on each end may provide the needed re-clock. (We had a show where the client was using a basic BMD HDMI to SDI micro converter, SDI to the stage, and then back to HDMI, and that micro converter didn't have enough power to properly drive the signal over that length. Adding another MD-HX to the stage end re-clocked the signal and got us up and running.)

For an install, the HDMI fiber cables work perfectly. No external power supply needed, like the SDI converters. Literally plug and play. They are not limited to 30-50ft like copper.
