The Tablo’s channel scan will display all channels your antenna is able to detect. It will also provide you with signal strength indicators.
One red dot:
You can expect video and audio break up in the channel’s stream, and it’s possible recordings will fail. If possible, try to improve your reception if you want to keep this channel in your Tablo’s lineup.
Three orange dots:
The video from this channel can be considered ’good’, with the occasional ‘blip’ in audio and video.
Five green dots:
The signal quality for channels with five green dots is considered excellent. There should not be any video or audio breakup in the stream.
What if your channels all have 5 green dots, but you’re still experiencing poor video quality?
