Anyone using a Fiber Optic HDMI for longer cable runs? If so what brand and length?
I have a new Epson HC 3800 4K Projector directly connected to a Telus 4 K PVR (VIP5662) using a Certified 4K 18gb (5 meter) HMDI cable, 4K Signal & picture is excellent.
I would prefer to have the PVR located at the front of the room, distance requires a 15 Meter HDMI cable to the Projector. I installed a Ruipro 15M Fiber Optic HDMI Cable to test if it works. When the PVR set to a resolution of 1080p all is good. If the PVR resolution is set to 4K the Projector indicates no signal. Ruipro has told it should work. Ruipro sent me replacement cable, same problem.
Many people are using these Fiber Optic HDMI cables a longer distances either this brand cable or a similar Monoprice Fiber Optic HDMI cables without any problems.
Here is a link to the specs of the Ruipro cable. My only thought on why 4K has a problem is the chips in the cable do use some of source (PVR) HDMI output voltage. And that maybe too much for the VIP5662W
Ruipro specs says:
Low Power Consumption: 250mW (max).(Power extracted from HDMI source)
Update: I installed an AmazonBasics Fiber HDMI 50' cable and it worked and I have not experienced any signal dropouts either. I have a suspicion the the Power Draw from Source(PVR) is less with the AmazonBasics cable. I do plan to get an newer AVR that will process/pass through 4K HDR 60 fps, perhaps a PVR=>AVR=> Projector setup will work fine with the Ruipro fiber.
