Initially, I'm not attempting any privateering activities. If that's the case, there are many more practical alternatives I could think of. Second, our shield is frequently used by children in the evenings, which means troubleshooting time is limited. My answers might take longer until I've had a chance to test them. My current configuration includes an Nvidia Shield Pro (version 2019) and a Samsung TV from 2014. I'm not planning to upgrade the TV because it still works adequately for me, and I don't want to spend excessively. When connecting an HDMI 2.0 cable between the shield and the TV, it operates normally. However, when I add a capture card with two HDMI inputs (identical on each side), the TV reports it doesn't support the resolution. The image captured from the card on the USB port appears as old-style TV noise, resembling an analog signal. The capture card in question is this one: https://www.amazon.com.be/-/nl/dp/B08X6X...ct_details. I suspect it's a generic model and the brand isn't crucial. Interestingly, it displays an image when booting the Shield in Safe mode (how to enter display safe mode) while the console menu remains active. But once I reboot into the normal menu, the display disappears. My assumption is that it defaults to 4K, which the card can't handle due to the TV's older panel, though I have no visual evidence. I've tried manually selecting a resolution in the shield's options menu, but it only offers 720p at 50Hz or 60Hz—no other choices. I prefer using a fixed resolution regardless. I understand the capture card might function because the console shows it, but I can't determine why it only displays that image. (For those curious, my goal is to use the card to power a Philips Hue backlight on the TV with Hyperion and an LED strip behind the screen.)

When using premium platforms such as Prime or Netflix, HDCP is necessary to prevent piracy via capture cards. ShieldTV likely enables HDCP by default, which is why it disables it in safe mode—this behavior probably accounts for your issue.

looks like i managed to fix it with a workaround. There is an app called Hyperion Android Grabber that sends my immage to my raspberry Pi running Hyperion. this is a low res immage but i only run 60LED's per meter anyway so i don't need HD capture. I had to sideload the apk as the store marks it as not compatible with my shield but it works fine. One sidenote. I only got it to work after i set the priority to 150 (it was 50 by default)
