This will allow your Android tablet to become a monitor for your AVR. I find this useful to show AVR screen instead of switching on the main TV/projector when listening to music or when I don’t need full size screen.
I used a USB Video capture card (bought this from Lazada for $14).
On my Samsung tablet, I installed a software from PlayStore called USB Camera.
Settings: Uncompressed, don’t flip.
Hope this might be useful to some people here…
