The output channel appears alongside regular digital terrestrial channels in the TV's channel list, with modulated resolutions up to 1080p. Unlike the standard TMX170HD, the TMX4KL includes a 4K-capable HDMI loop output, preserving the source signal at full 4K resolution for a directly connected display.\u003c\/p\u003e\u003cp\u003eRF Bypass ensures existing antenna signals pass through uninterrupted.
