Wrong colours when using external grabber

hyseroh · 27. November 2022

Hi everybody,

now that I've spent the whole weekend setting up my Hyperion, I'm giving up and turning to you guys with hope.

When using the Hyperion remote control, all colours are looking good, so the LEDs seem to work properly.

But when using the USB grabber which is connected to my Google Chromecast colours don't match the colours of the TV screen.

Especially yellow parts of the screen seem not to be transferred to the LEDs.

I have:

- Raspberry PI 3 B

- WS2801 LEDs

- Power supply

- Grabber:

- Converter:

Config:

Could anybody help me troubleshooting?

Please forgive me for being a Newbie...

Thanks in advance!

hey, i made a schematics which make it easier to see how to connect.

can u make a screenshot of the grabber like this?

so led and live video ON.

also may suggest you increase the SPI bus speed> set it to 1400000

Thanks for your quick reply.

Here's the screenshot:

Get a modern digital grabber from €10 and you then no longer need the converter which probably causes problems in connection with the grabber. With a digital grabber you get even better quality.

PClin is right on the money,

there is your problem, buy a coffee black 2.0 RULLZ LOOP device without the audio jack option.

or try this,

you can try to login as expert in Hyperion and then alter the encoding format but thats a stretch..

Is this a 4K Google Chromecast and do you have a UHD TV?

What is playing?

And how does the HDMI signal get to the converter and the TV?

You're awesome thanks!

This is my current setting:

(I tried both)

So this should be my

future setting?

Do you think that this will work? I mean the two input devices - each having an HDMI splitter.

Each device should be connected to an own TV HDMI port - else I have to configure my TV every day...

Do you think that this will work?

it could, but maybe you interfere with HDCP and such, that really can be a bitch to sort out.

this signals : CEC/HDCP/ARC or E-arc >> what do you want to do with those?

HDCP you can't avoid, so you need a good route from splitter and switch.

i show you my schematics how i made it on a Onkyo Receiver 1080P >> and it works with HDCP/CEC and E-Arc

Setup wiring/schematics for building of HDMI 4k tv route and/or 1080p route trough receiver >>> Hyperion

hello Guys of hyperion.

Let me start by explaining this topic,
I made a sollution for normal 1080P receivers and 4k HDMI/TV to "connect" them together and still have all the functionality of CEC/ARC/E_ARC/HDCP2.2 / Dolby/ Dolby + and so on, for every source now i have the HDMI HDCP2.2 to Ambilight!

I am very happy with this because now i can use my old receiver and new hardware together without having to switch HDMI cables when i want to use my receiver HDMI inputs, for example watching Bluray on…

Whoohooo! It works with my new HDMI Grabber

But only with my Chromecast.

Now I have to check Lightning Guy's proposal concerning DHCP and so on.

The 2 splitters and behind them a switch makes no sense. Unfortunately, since you didn't write anything specific, we can't really help you either.

I decided to only use the ambient lights for my Chromecast.

But today i noticed that it again doesn't work properly.

When turning on my Raspberry everything works pretty well but after some seconds or minutes (seems to be random) the LEDs go off and on. When checking the live video, there's the same. The screen offen gets black and there's a delay.

After some time the Hyperion Control Website doesn't react and I have to reboot my Raspberry.

It's the same behavior when using my Raspberry 3 and 4. (I use the latest HyperBian version)

What could be the reason for this? A bad digital grabber?

pclin · 10. Dezember 2022

Is possible, test the grabber on another device, e.g. a PC.
