HDMI 2.1 setup

  • I am coming from a Dreamscreen 4k with a WS2813 LED Stripes (44LEDs / M, 5.75m Roll, 253 LEDs) and am looking to upgrade. I now have a 4k@120hz 77" OLED, a powerful gaming home theater PC, and a PS5. I would like to be able to do 4k@120hz w/ ambient lighting and VRR. I think the following hardware will get me most the way:

    hdmi 2.1 splitter/downscaler https://www.amazon.com/gp/product/B0B7W94LHB?tag=hyperioforum-21 which will get me from 4k@120hz to 1080@120hz

    1080@120hz capture card https://www.amazon.com/dp/B073WJ2XTZ?tag=hyperioforum-21 will have to adjust for HDR in the software I guess

    Once I confirm its working with those I will get this splitter so I can have both PC and PS5 attached https://www.amazon.com/gp/product/B0BWCS32VC?tag=hyperioforum-21


    Now I am curious as to how I should attach this to my current LED strip. My plan is I would run Hyperion on my home theater PC. Then can I just use a ESP32 board like this https://www.amazon.com/gp/product/B09Z298QJQ?tag=hyperioforum-21 with WLED and send the signal from my PC over ethernet? Would rather not run a RPi if I don't have to, but if its better for latency I can. Should I change/upgrade my LED strip? Also looks like I can still use my Dreamscreen sidekicks as they can be flashed to use WLED https://www.reddit.com/r/dream…ick_with_wled_esphome_no/

  • You need a 4k@120hz splitter and switch and the splitter needs to be able to scale to 1080p 60Hz output for the grabber.

    The grabber must not be able to handle 120 Hz.

    The Y&H Grabber with Loop Out can only handle HDMI input resolutions up to 4K @ 30Hz.

    You don't need an RPI.

    The ESP with WLED is sufficient.

    Better results than WS2813 can be achieved with SK6812 RGBW or HD107S/HD108S


    If you have an LG TV, PicCap and Hyperion on the TV would also be an option, then you only need an ESP with WLED.

  • I haven't found anything that can change the refresh rate. Can Hyperion not accept 120hz even if its only at 1080p? Wonder if I got one of these if it would just drop the extra frames it can't handle https://www.amazon.com/dp/B09FLN63B3?tag=hyperioforum-21


    I was planning on getting the switch later once I got everything working. Here is a rough idea:

    Then later would add the switch if all works well:

  • That could work with the EZCOO splitter, then a grabber that can process 4K 60 Hz at the input.


    USB > HDMI Video Grabber, 1080p
    Mit diesem USB Grabber kann ein HDMI Gerät an einen USB Port angeschlossen werden. Der Grabber unterstützt Eingangsseitig Auflösungen…
    www.berrybase.de

    or a grabber with Macrosilicon Chip MS2109 and USB3.0.

    The lowest resolution that the grabber can output is sufficient for Hyperion, 640x480 60 Hz.

    The max. resolution of your LED is required, Hyperion has to calculate it down to that.

    60 Hz for the LEDs is more than sufficient.

  • Seem to be having trouble replying, my posts get auto deleted. Anyway, If you look at the details of the EZCOO on amazon it says it doesn't change the refresh rate:

    【4K 120Hz HDMI Splitter 1 in 2 out VRR G/Sync 】Aluminum 8K HDMI splitter for Dual Monitor Duplicate/Mirror; Distributes one HDMI source to two HDMI displays; IMAX HDMI splitter converter bypass HDCP strip for IMAX DIGITAL 2K-4K【Only OUT 1 support CEC; ONLY OUT 2 down-scale 4K 120Hz source to 1080P 120Hz TV, OR down-scale 4K 60Hz to 1080P 60Hz only. NOT down-scale 4K 120Hz to 1080P 60Hz,D-olb-y Vision input】To keep 4K120 stable quality,pls order together hdmi 2.1 cable B0BB78BFNJ

    So not sure if the grabber can downscale the refresh rate for me or not.

    NOT down-scale 4K 120Hz to 1080P 60Hz,D-olb-y Vision input

    Dolby Vision cannot be scaled.

    Ask EZCOO for this, Amazon is not a reliable source.

  • I know this was dated this is MY issue but, I was a big Hyperion guy on my setup. My Series X and PS5 could not be used with my setup due to HDMI 2.1 devices.


    Now that there is a flood of HDMI 2.1 devices, capture, splitters, etc, is there a solid HDMI 2.1 reasonably priced setup that blows away the Govee Camera setup I moved to that I hate ????

  • tell us your setup ( preferbly in schematics/diagram) and then i and others can help you.


    WHow many and what kind of HDMI sources?

    you have a AVR?

    setup TV?

    ARC?

    HDCP?

    Hyperion running on desktop/Raspi?



    etc etc.


    btw, You will never have a better screen grab directly from the source HDMI/screen grab instead of delayed images out of a camera pointed to a screen


    N-E-V-E-R ;)

  • Ok, I was a big Hyperion fan but, my setup is complex, I'll go through it....


    For the longest time, I had its setup like this. My AVR supports only HDMI 2.0b on this setup I have 2 HDMI monitor outs. I used to use this with Hyperion (PI 3b with a 4K 60hz capture device). Then the Series X and PS5 came in the picture with HDMI 2.1, my AVR does not support HDMI 2.1 but, my TV does.


    The AVR does deal with DVR and my Home theater PC so the HDMI switching is needed here.


    At this point running new consoles direct in the TV, then I was using ARC to run Atmos Audio back to the AVR, this worked fine but as you guess, my Hyperion setup didn't work with HDMI 2.1 devices. During this time, I decided this would never work with my setup (a lack of HDMI 2.1 devices for quite a wile) and moved to a $80 Govee camera setup and I HATE IT.


    Towards mid last year ARC just failed completely, something broke, spent like 3 months troubleshooting this and with 0 results. From that point could only get audio through the TV, no Atmos, nothing through my sound system.


    Now, I found a HDMI 2.1 Audio extractor. This solved the ARC failing problem. HDMI 2.1 devices run to this extractor, a passthrough cable goes to the TV, then an Audio only HDMI cable goes back the AVR, so I can get Atmos and other higher audio formats.


    Everything is completely macro'ed out via a touch screen remote, I can do complex wiring things and as long as it could be controlled via IR, you only hit one button to make the magic happen. I don't care about the device as long as it can be IR controlled; I can make it disappear.


    IN a nutshell, HDMi 1 on the TV gets AVR stuff and HDMI 2 gets 4K 120hz sources...


    What I was thinking... a HDMI 2.1 switch that is IR controlled, run the output from the Audio extractor on port 1, and AVR to port 2 (macro'd out on the remote), the ouput here would go into HDMI 2.1 Splitter, this pass through perfectly HDMI 2.1 devices but, one output would be 1080p 120hz, then go to Hyperion with a PI driving accurate LEDs.


    I think all I really need is a device that can take a HDMI 2.1 signal, OR a 2.0b (1080p @ 120hz is within spec on HDMI 2.0b) and capture video to import into Hyperion on a PI.....


    I am creative to find solutions for other things as you can see but, I want to get back into Hyperion for accurate LEDs...

    This should work with an ezcoo or FeinTech HDMI 2.1 splitter and a grabber that can handle 1080p 120Hz at input.

    There are now devices for this, for example an ezcap 321/Y&H HD60 or SIIG 4K120Hz HDMI 2.1 Capture Device could work as a grabber. Unfortunately there is no confirmed installation.

    So the question is what works with ARC/eARC, CEC, HDCP, HDR, and DolbyVision.

    Furthermore, which resolutions Hyperion gets and which devices can process the data stream.

    This shouldn't be a problem with Hyperion on a PC.

  • I actually own an Ezcoo HDMI 2.1 splitter (this is claimed to pass output and drop to 1080p 120hz on 2nd output). I was planning to use a PI 3b for this project if possible.


    Just posted here to see what works. I'm not worried about audio passthrough, just need something that by passes HDMI 2.1 VIDEO only without losing anything....


    ARC and CEC I don't care about but, HDR and Dolby vision are big ones..


    As I need to buy NEW LEDS and a capture card, I really want to know what works before dumping more money into this project.


    No one else here has run into HDMI 2.1 and Hyperion?

    There is no real confirmed install for 4K 120Hz.


    ezcoo and FeinTech should have no problem with HDCP, HDR, and CEC to TV. ARC/eARC none.

    With DolbyVision it could be difficult if scaling has to be done.

    The question is what matters to the grabber.

    Clearly HDR must be compensated for, DolbyVision no Ambilight.


    I only read about LG TVs with PicCap and Hyperion that can do this, but colors also have to be adjusted for HDR and DolbyVision.

    Unfortunately, I don't have any devices that deliver 4K 120Hz so that I can test it myself on my LG with PicCap.


    If you have an ezcoo HDMI 2.1 splitter you would still have to invest around €60 for the ezcap321 and could test and report. ;)

  • Of course, thank you for your help and the specs on devices. Do we know 100% that the Ezcap321 will work with Hyperion? Will Hyperion take in the 1080p 120hz signal over a PI and work with it?


    I see Aliepress has the Ezcap321 (one that does support 1080p @ 120hz) for like $48, it's fair cheaper there than on ebay, or what is on Amazon. It appears to be discontinued for a A/B/C version of it, but it's cheaper but, specs are lower. It might be the route I go.


    I didn't know anything or heard anything about PicCap, never saw it, my TV now (going to replace it in like a year) is a 2019 65" LCD based LG with WebOS on it... Noting you need to HACK the TV, don't care about that one. How do you get video signal out of the TV? It has no video out.


    I used cheap off the shelf LEDs last time, what is some of the better LEDs that work with a PI(3b)?


    Honestly, I am shocked that no HDMI 2.1 subject has not come up that much, or any confirmed installations. I figured this would be a very hot topic for those with this type of setup.

  • Ok, I was looking over things and realized that I needed to trash this project due to HDR. So far, it looks like I have all the hardware I need besides the LEDs and capture device (all sitting in my AliExpress wish list, ready to order) BUT, the ezcap321 does not support HDR.


    the horrible, laggy camera setup that I want to trash it, I use now, does work with HDR..


    This is a deal killer... it makes this kit worthless...


    I was looking into capture devices that support at least 1080p @ 120hz AND HDR and we are looking well over $250 for something like this that puts this project out of affordably. No way am I going to spend an extra $250 for this setup no matter how much I like it.


    I ran into this...

    GitHub - awawa-dev/HyperHDR: Highly optimized open source ambient lighting implementation based on modern digital video and audio stream analysis for Windows, macOS and Linux (x86 and Raspberry Pi / ARM).


    HyperHDR, this will work on the PI, analyze the video, when it detects HDR it will convert it on the fly.


    Has anyone used this with Hyperion? Or is this a whole different program? Kind of confused on what this is but, HDR is important to this project...

    HyperHDR is a hyperion.NG side fork software from developer Awawa

    if you have questions then he is your man.


    yes it runs on a Raspi, yes it can (sort of) cope with direct HDR signals/colourpalettes.


    the horrible, laggy camera setup that I want to trash it, I use now, does work with HDR..

    ofcourse, because you have no HDCP/DRM and all kind of protocols to worry about with a camera looking at a screen. But it's never the same quality than Hyperion in HDMI route.

  • Thanks for the info, looked deep into their GitHub and looks like it will deal with HDR and should work fine (with a bug that can be addressed) with my pi 3b that I will be using. I do need to find some more info how to set it up but, based on what I read it will deal with HDR and convert the colors on the fly.


    I'm 95% sure all my devices will deal with HDCP, as they should be compliant but, the 2nd out of the splitter dropping to 1080p 120hz, should still all work fine.


    I'll go forward and order the parts next week, once I set it up, I'll post back if it works and how well it works.


    Can't wait to trash the camera setup.... not even usefull...
