Your issue could be to a cable, but you would have to test that. I'm pretty much positive the problem I experienced with the picture going dark watching Kaleidescape isn't due to a cable. I have Celerity Fiber Optic cables, so distance shouldn't matter. From my rack to projector is 80 feet. My Kaleidescape Strato sits in the rack. All the HDMI cables in my rack are certified Belkin HDMI cable from Blue Jeans Cable. My UHD player sits inside the theater connected by a 60 foot Celerity Fiber Optic cable.
I have watched a ton of 4K HDR movies from my UHD player and never once had an issue. Literally perfect every time. Out of the probably 100+ movies I have watched in HD or UHD on my Strato I have only experienced this issue twice. Once watching "Tomorrowland" in HD, where it went dark four times for just a few seconds in the first few chapters, but didn't do it again. I restarted and watched the first seven chapters again and it didn't do it.
The second time I experienced it going dark was last night watching "Hancock" in HDR. The picture went dark an estimated 25 times for about approximately 10 seconds each time. This behavior occurred even after I restarted the Strato.
I have never had an issue with any of my sources going dark except the Strato. If there was going to be a problem with cables, mine would probably come from my UHD player watching 4K HDR movies over 140 feet of Fiber Optic cables. All sources are connected to my Yamaha processor, which has one single cable going to the projector.
I'm about 99.9% sure it is the Strato, firmware or an anomalous download that is causing the issue in my case. I am hoping to get to the bottom of it, because after spending all the money I did on my theater AND of course the Strato, watching a movie continually go "dark" even once is a REAL downer!
