JVC HR-1080-PRO Video Processor User Manual MKT-0027-UMN-1.002F
Input aspect ratio is determined by the JVC HR-1080-PRO video mode recognition circuitry. Only
two output aspect ratios are supported, 4:3 and 16:9
4
.
Inputs considered to have 4:3 aspect ratio are:
• Computer Graphics signals with a 4:3 aspect ratio appearing on the DVI and Analog
RGB inputs
• SDTV signals (NTSC and PAL derived) appearing on the Composite, S-Video, and
Component inputs
• SDTV signals (NTSC and PAL derived) appearing on the SDI input
• SDTV signals (NTSC and PAL derived) appearing on the HDMI input

The special case of 1280 x 1024 SXGA (an aspect ratio of 5:4) on output is treated as if it were 4:3. The output of
a 1280 x 1024 display will be slightly distorted; circles will appear to be vertically oriented ovals. Since the JVC
HR-1080-PRO is intended for Widescreen processing, the 1280 x 1024 SXGA is not a frequently encountered case.
Input of 1280 x 1024 will be treated as a pillar boxed 4:3 signal (i.e. it will have narrow black bars on the Right and
Left); aspect ratio of the picture content will be undistorted.
