Oder der klassische Aufbau über diese teil am zweiten HDMI AVR Ausgang? https://www.amazon.de/dp/B07255TVMC/ref=cm_sw_r_cp_tai_rfvZDbKJ4YHEW da der 4K kann sollte es doch auch mit HDR (zumindest die Anzeige am TV geben)
I bought the same hardware (VGB500 Grabber) and was about to send it back when I stumbled upon your message. I have the same setup: Raspberry Pi 4 and `hdmi_force_hotplug = 1` in /boot/config.txt. Raspbian Buster is fully up to date too. I tried installing hyperion.ng in its latest version, but can't seem to make the grabber detected. Would you mind sharing your config ? Edit: Actually managed to make it work I am not sure exactly what was the issue, I couldn't get the module uvcvideo, modprobe was throwing errors. I installed libuvc0-devel just in case. In the end, I rebooted the Raspberry and everything was detected properly. As far as my early tests went, it works perfectly with Kodi on one side and the PS4 on the other.
