SIIG Ultra HD 4K EDID Emulator for HDMI 2.0 3D, CEC, HDCP 2.2, Programmable EDID Copier and Manager, TAA Compliant (CE-H24Z11-S1)

I bought this to debug a really unusual setup — two camcorders running into Atomos Ninja V recorders, daisy-chained into an HDMI to NDI encoder made by TBS Technologies that for some reason can't handle the output of the Atomos (audio popping). I wanted to see if the problem was related to the EDID that the TBS encoder is sending out. (I can work around the problem with a splitter on the way in — but I figured maybe with this, I could provide info that would help these two companies figure out their firmware compatibility issue so that other folks won't run into it in the future.)I have have only just started playing with this device, but I have verified (by decoding the EDIDs on my laptop) that it does correctly capture the EDID that each TV/monitor sends, and replays it when a different TV is attached. Depending on which TVs we're talking about, this either results in a working picture or it doesn't.1080p TV's EDID on a 720p: Unsupported mode (expected)1080p TV's EDID on a 4K TV: worked.720p TV's EDID on a 1080p TV: failed.That last one was kind of strange. The TV got the signal, but almost immediately dropped the signal, so it kept appearing and disappearing. I'm not sure if this was an HDCP issue or was caused by the 25-foot HDMI cable between this device and the TV in question. My guess is the latter, as 25-foot cables are right on the edge of where you would expect to start having signal integrity problems. But during the brief periods where the TV was visible on my laptop, it was showing the expected EDID. :-)I guess the bottom line is that you should use this close to the device you're driving, rather than close to the source, but if you must put it far from the device, use an optical cable, rather than a traditional wire-based cable.One other thing that surprised me is that this device does not send out the EDID unless there is a monitor attached to its output, i.e. you can't use this to act like a monitor is attached if it isn't. I kind of assumed that it would always make the EDID available, but perhaps doing so would cause problems because of HDCP. No idea.My biggest complaint about this product, really, is their limited (and strange) choice of built-in EDIDs. They provide six different modes for 1080p, two for 1080i, and four for 4K, but zero for 720p, and zero for anything other than 60 fps. That rules out a lot of relatively common configurations. (And who uses 1080i for anything? I mean, I do, but I assumed that I was the only one in the universe!)If I were designing this, I would have used a bank of 16 DIP switches, with one switch per capability rather than a bunch of pre-built profiles, e.g.1 - Learned or hard-coded (with a separate learn button).2 - 720p3 - 1080i4 - 1080p5 - 2K/4K6 - 24 fps7 - 25/30 fps8 - 50/60 fps9 - 10-bit video10 - 12-bit video11 - 3D video (if anybody still cares)12 - 2-channel audio (A.K.A. the DVI/HDMI switch)13 - 5.1 audio14 - 7.1 audiowith a couple to spare for future firmware expansions. Unfortunately, they didn't do that, so there are a lot of useful configurations that can only be generated by learning. I guess that's okay; it would just be more useful if the pre-baked configurations were more useful. All the 3D configurations are likely to be a complete waste for approximately everyone, whereas a 30 fps 1080p mode would be really useful, as would some 720p modes.Still, if this device happens to be what you need (it's kind of an esoteric tool, not really useful for the average person), it does work, and I've generally had good luck with other SIIG gear over the past couple of decades (video splitters, SATA docks, SATA and FireWire cards, etc.), so I bought it in spite of only having a single rating with one star saying that it didn't work. Not sure what went wrong for that other reviewer. *shrugs*

I followed the quick start guide (which is literally the only resource available) and the device does nothing at all. No matter what switch setting is used the device does nothing whatsoever. I paid an additional $20 to get this item vs an identical item from competitor because I needed it quickly and am highly disappointed. I also contacted the support number on their website and was unable to speak with anyone, only leave a message.
