recently bought Nvidia shield TV giving "no signal" after nvidia logo with optoma uhd55 beamer in HDMI port 2 (only 3d input). HDMI which has no 3d works fine.

  1. Check your TV specs, because I would bet that the 3D input is limited to 1080p or something like that and your Shield is set to 4K.

  2. Try unplugging the HDMI from it, power cycle it, give it about 30s-1m to reboot then plug the HDMI back in? I've had this happen occasionally as well. I have to reboot every day to reconnect network drives.

  3. I've done that several times with no success. It just cant find signal after nvidia logo. Its like android kicks in with some type of configuration that is not compatible with my beamer
