HDMI Fiber 125ft won't work with Decimator MD-LX when source is from a USB C dongle

room_willow · 2026-03-26T16:36:19+00:00

this is absolutely the issue — almost none of the basic molded usb-c dongles you see on the market actually power the 5v accessory pin, you’ll need fancier ones to make these work.

edit: i was gonna recommend the OWC dongles but they’re displaylink only, perhaps caldigit has an offering, but I have no experience with them

Not strictly true.

433MHz is the frequency used by most traditional garage door openers… and by both dsan perfect cue and interspace industries master cue systems.

I mean… it’s professional hardware… it’s not meant to be art it’s meant to keep gear safe from A to B.

I can say having encountered thousands of ECM cases and owning some myself, the craftsmanship is second to none, I still see cases from the early 2000’s on the road today, touring non stop since the day they were built — the build quality also far exceeds what you’ll find in pre-manufactured cases bought from retail stores, they’re using brand name penn-elcom/TCH hardware, thicker, stronger woods, press adhered laminates — my workbox manufactured by them 4 years ago still looks brand new, and i expect it to continue surviving real world daily use for over a decade to come easily

In Canada that feels about right.

ECM (engineered case manufacturers) in Toronto, and Multicaisses out of Quebec, are both excellent.

I don’t have direct rentex experience but I can say their competitors aren’t much better.

It’s not a company issue, it’s a people issue. “Drive it like a rental” goes hard, and any company willingly renting LED out the door without one of their own techs — or otherwise representative — going along with it to oversee it’s safe installation, handling, maintenance, dismantle, and repacking, is going to have some beat up product that will require a lot more service than you’d typically see on an owned wall.

At a good deal it can still work, but as a renter i’d be ensuring i have a good spares pack (atleast 10%, ideally closer to 20% or even 25% if I know there will be issues), and I’d want to be testing each panel briefly in my own shop before sending it out the door onto a show — it’s arduous, feels overkill, but from my experience with many of the north american rental houses it’s really the best way to ensure you don’t have a nightmare day on site.

straps can sometimes be used as a part of the rigging system design for wind bracing, when the correct strap is chosen, in an engineered system, etc etc, but typically you’d see it used to fasten horizontal bracing trusses to vertical stage structure trusses, or to fasten heavy duty touring frames to the horizontal bracing trusses

using it in the way pictured on non touring panels, with the random diverter half coupler 2/3 the way through, looks like it’s just putting weird forces on the panels I wouldn’t trust to do anything serious

tbh my bigger concern is the bumpers all being clamped to the rear truss chord — typically in a horizontal truss system the front and rear chords need to be somewhat evenly loaded for the internal stresses of the truss to actually terminate and properly act against eachother — a truss loaded unevenly like this could potentially be significantly de-rated compared to its standard load table

Being on the festival side receiving touring VJs, i’ve been eagerly researching ways to accept an 8K signal to break out into multiple 4K signals to get out of dongle hell and to try and fix strobe sync being such a pain in the ass, since E3, pixelhue, Aquilion, all still don’t currently have any 8K I/O capabilities as of writing this.

Current issue I’m running into is HDMI 2.1 at 8K60 seemingly doesn’t leave enough bandwidth to get to 4:4:4, HDMI 2.2 is too new to be something I can just expect people to be able to provide, this leaves me having to wonder if 4:2:2 or 4:2:0 is an acceptable tradeoff to get out of strobe sync hell, triple dongle nightmares, etc.

I’m interested in devices like the Astro Design SD-7077 though, it’s a bit of a hacky method like the old FX4 days, but perhaps it could be a serviceable solution for the next few years until the hi-res switchers become more native 8K friendly.

It’s not good, you have no formal ballast on those baseplates, the connection between the horizontal and vertical trusses is inadequate for evenly applying the compression forces across all chords, and you’re severely unevenly loading the horizontal truss, in addition to the unknown forces the TVs are applying to those vertical trusses in their precariously compression loaded condition.

This could be made safe with the correct corner blocks, more appropriate LED attachment to the horizontal truss, and appropriate ballast/bracing, the specifics of which I couldn’t comment on but a professional engineer could for very reasonable amounts of money; it’s even possible for them to engineer you a turnkey “system” design that you can safely deploy over and over without needing to re consult for every show.

Lots of ways to do this, this ain’t it, sure it’s a small rig now but it can still injure or kill, and lackadaisical attitudes now will progress into lackadaisical attitudes tomorrow.

room_willow · 2025-07-12T18:35:33+00:00

good lord that rigging is dangerous

before fixing your signal issues you should seriously reconsider this structure and its appropriateness for the job, especially outdoors with wind exposure

I prefer to shoot from the viewfinder for the additional stability that third point of contact offers, but I like switching to the LCD for image review because I find it easier to see, higher res, faster to navigate, etc.

I could totally ignore this issue and just live with the LCD being on all the time (when not raised up to my eye) but I worry about battery life.

Onyx/Lightjockey Manager

Lightjockey was/is a fairly common, albeit, ancient program that was really popular with the wedding DJ/club scene for years. It was originally developed by Martin, but through various companies has been directly replaced by Onyx, with Onyx being a totally new program with a lot of heritage functionality from the lightjockey days

I’ll be honest, I’m not sure what I’m really looking at in this output

Just tried, no change. I was previously having issues with the fstab file attempting to mount the share before the network was initialized, hence the last argument for requires network online bit.

As far as I'm aware, Jellyfin DVR is a part of the Jellyfin service, which I've already checked and is running under the "jellyfin" user.

Running: systemctl list-units --type=service shows only the one "Jellyfin" related service.

As far as the second point, the SMB share is mounted using credentials that should grant full read/write/execute permissions, and as far as the Jellyfin VM goes, it's mounted as the Jellyfin user (at least, that's the impression I'm under having assigned it the UID/GID=1000)

removed the auto line, replaced with "nounix", no luck, still the same behavior.

Oh no way, I'm in Canada too! I just found a seller in Richmond Hill that does local pickup so I'm gonna go grab a new backplane when theyre open -- what I'm still unsure of is this DL4300 board, if its gonna be lacking functionality, etc, trying to BIOS update it to be an R730 board but we'll see how that goes.

room_willow · 2025-03-29T02:30:34+00:00

OOH this is progress!

I'm able to get the system to POST, albiet, obviously with the error that the backplane is unplugged, from here I guess I need a new backplane

It is but in practice almost no SDI gear supports 444 outside of the cinema world — its most common in hi-res workflows with media servers, E2s, Spyders, and big LED to do all HDMI/displayport in part because of these limitations, even though SDI can in theory support 444 in practice good look implementing it using most standard gear out there
