ISSUE What am I doing wrong?

What am I doing wrong? Brand new setup. I have the following:

The LEDs are reacting to the input, but the colours are all wrong. I’m using WLED to control the LEDs and they work OK with that but with Hyperion they are all wrong. See photo.

 

Maybe your ledconfig in localip:8090
Change the RGB setting into GRB or something else

 

I did try that. RGB is correct. At least. If I set a static colour in Hyperion the correct colour is displayed. It seems to be the capture that’s wrong.

 

Check the captured video in hyperion web interface. Is it correct? Also check the logical position of the first LED, direction, number of led etc.

 

It looks correct although the image doesn’t look 100% in the the web page. I assume that’s just because of some compression or something. The LEDs start top left and go across the top of the TV. Shown by the grey dots on the LED display.

 

Also check your USB grabber settings, if size decimation is too high then colours wander of also.

Set it on 4 and see what happens.
Set on PAL (ntsc will sometimes rumble colours)


Goodluck.

 

This is what the web page sees. (Attached).

just tried those settings and no luck I’m afraid.

 

Could it have anything to do with the Fire TV using Dolby Vision with my OLED TV?

 

The grabber seems to put a red colour on top over everything so that all colours are mixed with red hence why the resulting colour isn’t right. Even when the screen is black the LEDs are red.



not sure why the bottom photo is upside down.

 

I think it’s the Dolby Vision. If I set the display to 1080p and turn off Dolby Vision it works.

 

The preview is a garbled mess (which I thought was right through the webpage) when using DV.

 

yes. HDR still seems to work but when the TV detects a Dolby vision signal is when it stops.

 

If seems that the HDMI splitter supports Dolby Vision if you are just splitting it, but cannot downscale it. So on the lookout for a new splitter with DV support and down scaling.

 

So on the hunt for a Dolby Vision supported HDMI splitter, ideally with multiple inputs.

 

You can avoid the red lines, when you crop the screen in the USB capture menu. Had the same issue.

 

Sorry I should be more clear, it's not just read lines on the edge, it's the whole screen due to the capture device and splitter not supporting Dolby Vision.

(this is what it looks like - not my photo)

The HD Fury Diva is the only thing I've found that will fix your issue. I think they offer something else that would work, but it requires you to have an HDMI splitter that already up/down scales property. Plus the Diva offers a few extra HDMI ports that will work with DV and all the new DHCP standards. I highly recommend a Diva if you want the best out of your 4k display.

 

For now I'm just living with DV not working. I don't actually watch that much that is DV, most stuff is straightforward HDR which works fine.
