BlueJeans cable owner signing in here:
Well this seems like the right thread to post these questions in, as I'm now re-entering the horror show that is the world of HDMI syncing.
My system has the source components in one room, and I use two 45 foot long BlueJeans Beldon HDMI cables
(the top version rated for longest runs) to the room with my projector. This has worked great for the last 5 years, passing 1080p, 3D and also 4K signals (1080p upscaled to 4K and output from my Lumagen video processor) with no problems.
BUT...I just replaced my JVC projector (2 years old) with the latest model and now I can't get a picture. The latest models are fully UHD compatible "Dual Full Speed 18Gbps HDMI/HDCP 2.2 Compatible Inputs"
Hooking up the new projector to the existing HDMI cable run (back to my Lumagen doing the video switching) completely freezes the projector, not only no picture, it makes it unresponsive to all commands. I tried bypassing the Lumagen etc, running the one of the 45 foot HDMI cables directly into the projector, and that works fine. So it's something about the communication with the Lumagen.
On bringing this up in the Lumagen threads, they are suggesting I'm probably running up against a cable limitation - the chips in the Lumagen, and now my new JVC, are a bit more demanding and finicky, so this long passive run may have met it's match.
Does that sound about right to folks here?
(It's been suggested I place the Lumagen VP at the end of the long HDMI cable run, and run a 6 foot HDMI cable from the Lumagen into the projector, and if that works it suggests cable limitations being the culpurite).
Anyway....IF I have to re-cable like everyone else I want to do it right, especially as the cables run through basement ceilings through rooms etc.
Would a redmere type cable of 45 feet be a good bet? Or an HDMI Balun? I'm not sure what the advantages of one over the other are.
Finally, I see people say that Cat 6/7 is the cable to run if you just want to be more future proof. So why isn't everyone just using Cat 6/7 rather than fooling around rolling dice on all the HDMI cables? Would it make sense to just go Cat cables? (I guess they just terminate them with HDMI connectors or something?)
