Video Scaler (1080p to 4K) with Super Resolution

Ultra HD, usually referred to as 4K, is the next
generation ultra-high-resolution standard with
3,840 x 2,160 pixels or 4,096 x 2,160 pixels—four
times the current HD 1080p standard. By
detecting the fine texture in the image and
applying appropriate compensation, a more
detailed and beautiful image is created. This high-grade HD
video is further elevated to an even more detailed, natural and
realistic picture with the video scaler featuring super resolution.
The AV receiver upscales 1080p video sources up to 4K/60p
high-resolution images (4K/60p/4:4:4/24-bit, 4K/24p/4:4:4/36-
bit, 4K/60p/4:2:0/36-bit) for viewing on a 4K-compatible display.
The AV receivers support 18 Gbps bandwidth, allowing
reproduction of 4:4:4 colour format, and are ready to bring out
the best from the future generation Ultra HD devices with 18
Gbps transfer capabilities.

The feature lets you take advantage of the
highest-quality video source, by passing through
4K/60p signals for viewing on a compatible
display. The AV receivers support HDCP 2.2, so by
connecting to a compatible device, you can enjoy
premium content such as 4K videos with digital
copy protection.
* VSX-531 supports up to 4K/60p/4:4:4 on all HDMI terminals.
VSX-1131/VSX-831 support up to 4K/60p/4:4:4/24-bit with

Next Generation Video Standard Ready

The AV receivers are ready for the next generation video
standard HDR (High Dynamic Range) and BT.2020*, which were
adopted by Ultra HD Blu-ray™. HDR is a technology that
drastically expands the brightness peak, providing a higher
contrast between light and dark images, which creates even
more life-like pictures. BT.2020 is a new colour-recording
technology allowing a much wider gamut than the current BT
709 standard, enabling vividly rich colouration.
