Just to update all, I've solved my cropping issue with the direct HDMI grabber (purchased the Nsendato version of aliexpress for $14). When I changed my hyperion config to PAL, it stopped cropping the right and bottom. It's almost perfect!

Here's the big issue and bc I do not understand the back feeding power concept, I wonder if my issue is due to this grabber. I've got the HDMI usb grabber plugged into my Pi (and to fast forward, now it's plugged into an external powered USB hub. My HDMI splitter is attached to the same power supply as my PI, the USB hub is on a different power source.

Without fail, watching the fire TV, every few min my playback pauses. I've pretty much isolated to the HDMI USB grabber. I'm fairly certain it's something to do with this back feed power issue? I think what's causing the playback to pause is either some surge or power overload with my splitter. The funny thing is that even with the splitter output going into my HDMI USB grabber, but not plugged into the USB hub, the video will still cut out occasionallly. This I don't understand but after reading some of these posts about the HDMI powering the grabber/Pi, maybe this is my issue.

Any ideas here on how to stop. I love the color over my HDMI2AV converters, but can't use this with constant pausing.

I tried and it's ok, but when the player switch to 24 Hz, crop again...

I tried one, but seems that in 24p mode, the capture is wrong. It's like the image is displaced to left...so the right side it's black. Anyone?

1080p@60 it's working perfectly, but at 24 hz...see the pic.

Yes, exactly:

SDR:

HDR:

More tests: DV it's working BUT Hyperion only detect the dolby layer like this:

4K HDR works fine but I think It's a litte washed...

Yes, I tested without grabber/cvbs and the same: DV its not working.

Finally I received mine. Works ok, but the second HDMI Out it's 1080p but not converted to SDR. So, looks like this (I played Blade Runner 2049 from my Apple TV 4K HDR BT.2020 10 bits, the other HDMI it's going to CVBS and then to the grabber and Pi3):

And Dolby Vision doesn't work. If I try to enable it from Apple TV 4K, the screen goes red/green like 2 bit gradation...

So we need HDR to SDR conversion...

Just got my Ezcoo splitter/scaler yesterday, not 100% but it does look like it strips HDR from output 2 when scaling is enabled. I can upload a picture from my tv and one from my video grabber for comparison.

Well, mine comes tomorrow!

The 1080p downscaled signal is in HDR or SDR? I would like to know if the ezcoo also convert HDR to SDR. Because If not, the grabber capture too washed out image.

Another one bought here.

Now the question is change the gamma from the capture, maybe with 3d lut correction.

We're talking about here: https://hyperion-project.org/t…d-3d-lut-correction.2594/

Hi!

I just bought this 4K Splitter (HDCP 2.2 + HDR) + Scaler, that works nicely downscaling 4K HDR 10 bits BT.2020 to 1080p: https://hyperion-project.org/t…ter-supposedly.631/page-5

The package has not arrived yet. I am using the APA102 directly in the Raspberry Pi 3 (with level shifter), any way to implement the 3D Lut correction in it?
