HDMI?
Yes, because HDMI is
If your DVD player is equipped with HDMI 1.2a, the HDMI connection will permit the transmission of 1080p (high definition) video signals.
Which is the best way to rescale the picture?
When using legacy components that require picture rescaling, it is better to use the monitor scaler to handle any picture resizing. You should try to use only one scaler in the system, so keep your DVD player set to 480p or 1080p. A 480p signal will be rescaled by the monitor and a 1080p signal will be seen by a monitor with 1080p resolution as a native signal.

Will the HDMI digital output improve the picture quality from old analog sources?
Analog picture sources from legacy units begin by being less good than digital signals, and while the receiver will translate them into a digital format, the final quality will be constrained by the original source, and the choice of connection (Composite,
Why does the HDMI connection sometimes not give a picture?
Although it is simple to use, the HDMI connection is actually a highly complex electrical circuit, and within it is a security system called HDCP (High Definition Content Protection). In some circumstances pictures may not reproduce, or may not reproduce properly, due to the action of DRM (Digital Rights Management) or the ‘handshake’ between
the two connected units. HDMI cables contain circuits that exchange a ‘handshake’ signal several times a second, designed to maintain the integrity of the transmission signal and to prevent attempted unauthorized copying of copyright material. However, these ‘handshake’ signals can be disrupted for several reasons. If problems persist, consult your Rotel dealer.
