There are two settings that do completely different things, Video Convert, and IP Scaler. The Video Convert setting, when turned on, allows the AVR to superimpose text on the display screen, such as the volume slider, status messages, etc. Normally, you would want this setting turned on.
The IP Scaler converts incoming video signals to a resolution that is negotiated between the AVR and the display, based on EDID information shared during the HDMI handshake. For example, if your cable box outputs a standard def signal, and the AVR IP Scaler is set to 1080p, than the signal gets up-converted to the higher resolution. If the input signal is already 1080p, than no up-conversion is required, and the setting of the IP Scaler doesn't affect the signal.
Even if you don't up-convert signals in the AVR, they will be up-converted by the TV display, so it becomes a question of which device does a better job of converting the signal. With today's electronics, it will likely be difficult to see any difference.
