You can specify the output resolution for the HDMI OUT 
and have the AV receiver upconvert the picture resolution 
as necessary to match the resolution supported by your 
TV.

■

`

Through:

Select this to pass video through the AV receiver at 
the same resolution and with no conversion.

`

Auto:

Select this to have the AV receiver automatically 
convert video at resolutions supported by your TV.

`

480p, 720p, 1080i, 1080p:

Select the desired output resolution.

`

1080p/24:

Select this for 1080p output at 24 frames per second.

`

4K Upscaling:

Select this for an output resolution four times that of 
1080p, resulting in 3840 × 2160 pixels.

• Depending on the incoming video signal, the video playback 

may not be smooth or the vertical resolution may be lowered. In 
this case select anything other than “1080p/24”.

If you connect a video component to an HDMI input, you 
must assign that input to an input selector. For example, if 
you connect your Blu-ray Disc/DVD player to HDMI 
IN 2, you must assign “HDMI2” to the “BD/DVD” input 
selector.
If you’ve connected your TV to the AV receiver with an 
HDMI cable, composite video and component video 
sources can be upconverted

*

 to HDMI. See “Video 

Connection Formats” for more information on video 
signal flow and upconversion (

Here are the default assignments.

BD/DVD, VCR/DVR, CBL/SAT, GAME, AUX, 
TV/CD, PORT

`

HDMI1, HDMI2, HDMI3, HDMI4:

Select a corresponding HDMI input to which the 
video component has been connected.

`

- - - - -:

Select this to output composite video and component 
video sources from the HDMI OUT. The video 
signal from the HDMI output is configured in 
“Component Video Input” (

Each HDMI input cannot be assigned to two input 
selectors or more. When HDMI1 - HDMI4 have already 
been assigned, you must first set any unused input 
selectors to “- - - - -” or you will be unable to assign 
HDMI1 - HDMI4 to other input selectors.

• When  an  HDMI IN is assigned to an input selector as explained 

here, the same HDMI IN will be set as a priority in the “Digital 
Audio Input” (

page 41). In this case, if you want to use the 

coaxial or optical audio input, make the appropriate selection in 
the “Audio Selector” setting (

page 49).

• The  “TUNER” selector cannot be assigned and is fixed to the 

“- - - - -” option.

• Do not assign an HDMI IN to the TV/CD selector while “HDMI 

Control (RIHD)” is set to “On” (

page 51), otherwise 

appropriate CEC (Consumer Electronics Control) operation will 
not be guaranteed.

• If you assign “- - - - -” to an input selector that is currently 

selected in “HDMI Through” (

page 52), the “HDMI 

Through” setting will be automatically switched to “Off”.

• If you connect a component (such as UP-A1 Dock with docked 

iPod/iPhone) to the UNIVERSAL PORT jack, you cannot 
assign any input to the “PORT” selector.
