There are 1,5m + 0,25 + 0,25 + 4m = 6m HDMI in total where the last 4m are "repeated" from the HDMI splitter ... and yes the contact resistance for the terminals and HDMI PCB Boards

The fact that this occurs just after a while might also indicate a temperature issue ... so yesterday everything was fine for 30minutes and suddenly starts with blackscreen dropouts ...

I connected now the input and output HDMI cables from the AV Receiver/TV directly to the splitter and dont expierienced any droputs for hours, but yes ... i don't have cec with this ...

Is it possible, that after a while the devices starting communication via cec and therefore "negotiating" signals leading to this droputs?

How to troubleshoot this?

Okay, the suggested HDMI PCB Boards finally arrived, but as far as i connect them between my current HDMI connections i again get dropouts of the signal every few seconds/minutes ... its the same as i had before with a broken socket of my housing ...

But if i remove for example the HDMI sockets ( the are just for pass the signal from the outside to the inside of my lightberry housing) from the chain and connect it directly to the PCB adapter its working fine again. But also without the PCB connector and only connect it to the housings pass-through sockets in the chain its working fine ... but both together does not seem to work somehow.

The non working chain is:

HDMI Cable Signal In (male) -> HDMI Pass through socket (female->female) -> 15cm HDMI cable (male/male) -> HDMI PCB Board (female/male) -> Splitter Signal In (Female)

The working ones (but not sufficient for use case):

HDMI Cable Signal In (male) -> HDMI Pass through socket (female->female) -> 15cm HDMI cable (male/male) -> Splitter Signal In (Female)

or

HDMI Cable Signal In (male) -> HDMI PCB Board (female/male) -> Splitter Signal In (Female)

I also replaced the hdmi cables with no luck.

I fear that HDMI doesn't like much transitions at all, so if you put adapter to adapter, at some point the signal is really unstable.

Its sooo annoying, since it feels like failing at 98% reached goal

If i do not downscale, i have similar effects like with the FeinTech splitter ... everything is pink etc. ... i think this was exact the issue for the FeinTech. The automatical downscaler did not kick in for my new grabber since it supports the 4k stuff ... if i have the downscaler on for output2 (grabber) on the ezcoo, everything works like a charm! Yes, the HDR/dolby vision is darker than the usual tv stuff, but in this case i like the decent ambient bringing the focus more on the dynamic picture instead.

If the CEC solution will work in addition, this is a nearly perfect solution for me ... the only thing i can imagine to be improved is the possibility of ARC ... but honestly ... i can't imagine a use case for now bringing the internal sound of the tv to the AV Receiver somehow ...

MS2130 only makes sense with USB 3.0 and a powerful device,

What do you mean by this? I have it run on an old raspberry pi 3b+ with no usb 3.0, but it works anyway ... do you think it might consume too much power over time and might "overheat" ?

if anyone is interested in the setup, i can post current one.

but where to buy?^^

Ahhh ... do you mean this? OTOTEC doppelseitige Breakout Board Stecker Mini Stecker Leiterplatte

That looks like an solution since its easy to solder^^

I the meanwhile i found out, that my "old" ezcoo 4k splitter is doing it very well with the new grabber ... i replaced it only because it cannot handle CEC which is absolutely dumb in my eyes, since its just connecting an additional pin ... so i have a ezcoo splitter which can also handle dolby vision / and even hdr (yes, really! The image is a bit darker overall which is ok, since its at least not pink but a bit less intensive) and i have the CEC compatible Feintech which cannot handle any 4k signal for the second output ...

Soldering in general might not be a problem but not in this micro scaling ... its pathetic ... but i dont wanna buy another splitter ...

Maybe i switch just to a fixed background light, its very exhausting at the moment^^

Hmm I tested with the capture device on my macbook and there its the same purple/green oversaturated colors. So I think its a matter of the capture device.

I think it has to do with the resolution at all, so my device before was just an analog capture box with much less resolution ... since the new device accepts 4k, the splitter will not downscale to any less resolution automatically. Doing it via EDID mode = "STD", any of the devices are in fullhd, which is also not wanted ...

Might it be better to just look for a "FullHD" capapble capture device to force the downscaler automatically to max FullHD?

On the other side, i dont know why the MS2130 is recommended if they dont work with 4k resolutions

I ordered this capture card recently https://www.amazon.de/dp/B08Z3XDYQ7?tag=hyperioforum-21 to replace my old fullHD setup with a 4k compatible one. It has a MS2130 chip as they mentioned on the product page.

The chain is the following:

Apple TV4k -> Denon xhr1800 -> feintech VSP01201 Out 1-> TV

Out 2 -> MS2130 Video Grabber -> Hypercon (Hyperion) -> LEDs

In usual SDR / FullHD content everything seems to work fine, but in any of netflix or amazon (4k) content, the video input turns pink/green, which messes up the led colors.

The EDID mode of the Feintech is in "TV". When i switch it to "STD" it works again with any content, but the TV then only receives FullHD which makes the whole setup obsolete.

By the way, I dont get this STD/TV mode at all ... following the description of the feintech support page it should also work with 4k in STD mode on output 1, if it supports it, but that might be another story ...

I am aware, that no dolby vision nor HDR content ist working with the hyperion project, but "usual" 4k TV should work, or doesnt it? What i am doing wrong?

Might it be, that the MS2130 video grabber is not capable of it? What else can i try?

Thanks

Got also APA102 from Aliexpress .. my grabber does not produce that noise so much ... i am sure, that has something to do with the software and not with hardware since the internal grabber and solid colors are very stable, no matter which brightness or speed ...

okay, with change to NTSC: no approvement ...

As a side note: I already ran this setup with a WS2812B Strip with no problems ... this may have to do something with the APA102 ... but i dont know what

Hi all,
i am running into exactly the same problem ... i got an RPi 2 with APA102 ...
On bright scenes, no problem but on darker scenes there is a nervous flickering on some LEDs, especially the non-white ones.
I tried / changed nearly everything. There is no flickering on my captured image. If i freeze the screen you can see it very clearly. This must be some interference stuff impacting the grabber chain since there is no problem with testing internal grabber or setting solid colors from hyperion client. Ill try the ntsc workaround but i am pretty sure that will make no difference ...
