Luma Delay
There are two options (0T and 1T) "Luma delay" is just what it says, a time delay
applied to the "Y" or brightness video channel. Its purpose is to allow you, if
necessary, to compensate for the fact that some displays (through a composite
connection) will delay the colour signal, so that the colour in the image is shifted
slightly to the right. This is normally not needed to be adjusted.

About HDMI
HDMI (High-Definition Multimedia Interface) is the newest interface for
audiovisual equipment such as high-definition television and home theatre
systems. With 19 wires wrapped in a single cable that resembles a USB wire,
HDMI is able to carry a bandwidth of 5 Gbps (gigabits per second). This is more
than twice the bandwidth needed to transmit multi-channel audio and video,
future-proofing HDMI for some time to come. This and several other factors
make HDMI much more desirable than its predecessors, component video,
S-Video and composite video.
HDMI is an uncompressed, all-digital signal, while the aforementioned interfaces
are all analogue. With an analogue interface, a clean digital source is translated
into less precise analogue, sent to the television, then converted back to a digital
signal to display on screen. At each translation, the digital signal loses integrity,
resulting in some distortion of picture quality. HDMI preserves the source signal,
eliminating analogue conversion to deliver the sharpest, richest picture possible.
Though standard HDMI or "Type A" has 19 wires, "Type B" will have 29 wires. The
latter is targeted for the motion picture industry and other professional
applications. Both varieties are "Intelligent HDMI," referring to the built-in
capability for HDMI-enabled components to talk to each other via the interface.
Auxiliary information can provide all-in-one remote functionality and other
interoperable features not possible in previous interface technologies.
HDMI supports standard video formats, enhanced video and high-definition. It is
also backwards compatible with DVI (Digital Video Interface).
