I tried this once, and it totally didn't work. We ended up sending 1080p and upscaling on the datapath. But this was years ago and the boxes used had alot to be desired. but my gut instinct is that you need to send DVI-DL to get true 4k. Its the only way i ever got an X4 to take 2160@30. A good test is can you get 4k into the X4 with that same active adpater from a computer? If you can't get that working, you're cat5 box probably isn't either.Wasko wrote: ↑Tue Jun 26, 2018 20:30Hi Guys,
My goal is to output video from my server over distance to two datapath x4's to simplify setup (3840x2160 @ 30hz to be split to 4 1080p outputs).
I've heard of this being done with fiber optic cable, which is outside of the budget from what I've seen in my research.
This is the basic pipeline I am envisioning (in order):
2 Displayport Outputs @ Server
2 Active Displayport to HDMI adapters connected
HDMI to HDMI over Cat5 Transmitters
Cat5 to HDMI over Cat5 Receivers
HDMI to DVI-D Active Adapters
DVI-D to 2 Datapath X4's (3840x2160 @ 30hz)
I am not sure if such a thing as a HDMI to DVI-D adapter exists, for one.
I also know some HDMI over Cat5 extenders may not transmit 4k.
This seems convoluted to me at this point, I am confident there might be a better way to do this.
This would certainly be simpler with a fx4, but I have heard of others on this forum achieving this with an x4.
Please advise if you can, thanks!
If you're going 75ft, you should be OK with DL-DVI cables and a booster. I would do 50ft>booster>25ft. I typically use Cable Matters cables and they seem to work great and here is what I use as a DL-DVI booster.Oaktown - about 50 - 75ft would probably do it for the event that's soon on the horizon. In the future, the end goal would be to send the 4k signal up to my two datapath units on truss, as I have read you describe before. It was actually one of the deciding factors in buying these two x4's.
Using SDI out of your X4 works as well but now you're dealing with 1 adapter and 2 converters per output (DVI/HDMI -> HDMI>SDI and SDI>HDMI) AND you have to run SDI everywhere.Drazkers - I'm completely open to using SDI, and some of the AV companies in my city have some equipment for rental. Most of it from what I am reading will not support 2160p @ 30hz (like the Theatrixx Xvision SDI Converter). The other complication with SDI/HDMI converters (and HDMI in general) is the task of converting it back to DVI-DL to go into the Datapath, which is not as simple (or inexpensive) as I would have thought.
If you don't have the X4 hardware yet, I would say get the FX4 and use HDBaseT instead of fiber optic. If you already have the X4 hardware, I would think the way to go is fiber optic. I have used the Gefen extenders for years and love them as I have never had any issues! But my ultimate recommendation would be to sell the X4 and buy FX4 + HDBaseT instead of investing into DL-DVI fiber optic. You could also go HDMI over fiber optic, check out the datapath.us weblinkHaving said all this, I'm definitely open to getting the right gear to accomplish what I'm looking to do within financial reason. It's just narrowing down the right converters / cabling for the job.
I’ve ran countless shows and never had an issue so can you elaborate why you don’t trust HDBaseT?I personally don't trust HDbaseT for concerts. If it's an install you're golden. But that's not the case for me.
In my experience in concerts, companies that use HDbaseT, love buying the cheapest alibaba part. So black outs, flickering and randomness gets put on cat5, but really it’s the worst gear with poorly upkept cables ruining the rep.
I can see why cheap Chinese know-offs would be an issue but it would be the same problem whether you use HDBaseT or Fiber!In my experience in concerts, companies that use HDbaseT, love buying the cheapest alibaba part.

My tour rider prohibites cat5 not because of the tech but because of the chances of failure in the festival game. Also it’s easy to carry afew decinators to fix things. So that’s my reason, not the tech just the very wide range in quality.
