So just got a 2017 shield for less than $100. It’s very good hardware as the flexibility with android OS is very nice.
The shield remote was a little challenging to work with my ROKU TV. You can set the remote to work and control power and volume. But the HDMI INPUT is kind of hidden. You might need to select input to view your shield device.
The trick was to map/change the hamburger/menu button to use a double press to change HDMI INPUTS. At least that is what I did. You can map buttons to do anything as that is built into the shield. It’s just that the HDMI INPUT is not setup with anything at first with ROKU TV. Weird.
If anyone knows if a more simple way with the old 2017 remote for shield, please let me know.
