Well it was a combination. I think they were all monoprice, but it was sort of a hodge podge. I think the main cable to the projector was a 50' Monoprice 22awg. Not high speed, but had that far proven itself perfectly capable of up to 1080p60. I think the rest were either what came with products or some short, monoprice High Speed cables.
I think I replaced it all with BJC, the main run to the projector is now a 25' BJC Series 1 (certified HIgh Speed at that length) and the rest are IIRC, the Tartan 28AWG ones, 7ft from BJC.
I wanted to blame the Darbee/50V/etc too, but after a bit of reading around, and advice from Anthem and Lumagen I've seen, I bit the bullet and replaced my cables with known certified High Speed cables of reasonable length and my issues disappeared.
Oh, and it's not like it was super expensive or anything, the 25' Series 1 cable wasn't the cheapest you can get but it is about the longest actually certified high speed cable out there (at least that I'd seen)
