I’m currently using a Hisense Roku TV with a custom DIY ambilight bias lighting setup. The bias lighting setup uses the TVs USB port to power a USB HDMI capture device. It’s awesome btw.
However; with the TV “off” the USB still powers this capture device and has enough power to slightly light up the LEDs.
Is there a way or can I suggest being able to control the USB’s power settings when the TV is “off”?
